After acquiring a Toshiba laptop battery, to begin with, you need to know that it needs to be broken in first before you start to use the laptop computer. They need a first charge of twelve to fourteen hrs – and this must be done on the AC wall adapter – rather than any other charger, such as a car adapter. It doesn’t matter what any charge indicator sign says, wait the full time before disconnecting. It is recommended that you fully charge and discharge your new battery 2 to 4 times to allow it to reach its maximum rated capacity. This could fully condition the battery.

Generally speaking, the present notebooks drop its autonomy primarily by reason of a couple of reasons: Firstly the utilization, secondly the normal aging of the chemical materials. For that reason, regardless of what the tips that you will take your battery pack will wear as time passes.In general the life of a rechargeable laptop battery using is generally up to 2-3 years.

Just some normal proper care of the notebook battery can absolutely help to make a positive change in how long your battery will last as well. Here let me present to you some helpful suggestions on prolonging the lifespan of a Toshiba laptop battery to guarantee you can take most benefit of it.

The very first thing to understand is that it loses a little its load permanently even if you do not use it. More the temp of the battery is, more quickly it discharges. Hence to preserve your battery as fresh as possible is the first thing to do.

Moreover, by no means use or keep the battery in severe conditions, including leave your laptop computer in your car when it is either freezing out or in a hot summer time.best temp to keep the battery is about 15°C.In contrast, to cool too much your battery (such as for example by arranging it in your refrigerator) risk to damage it definitively. If the battery will not be in use for a long time, it is suggested to be detached from the machine and placed in a cool, dry, clean place.

Another idea to realize it is that the autonomy of the battery cut down a little bit with each charging cycle. Just what is not shocking, but when one combines it with the preceding point that can involve unexpected consequences: When a user leaves his battery in his device yet keep his ac adapter linked with the socket, the Toshiba laptop battery of its computer passes constantly by cycles of charge/discharge!

Toshiba Battery which remains to be utilized inside a laptop discharges somewhat more speedily than usual because of the heat revealed by operation from the laptop. Once that the level of load goes down less than a fixed amount (different for each manufacturer), the adapter reloads the battery until the maximum. As the battery ages this cycle is increasingly short what still speeds up the degradation of its autonomy.

Hence, when not using the Toshiba laptop battery, outside of your laptop in a fresh and dry location. Every couple of weeks exercise your battery. This is just a natural method that your battery needs to go through that allows you to retain its long battery lifespan. Toshiba laptop batteries are a product of first-class design, and need to be carefully care to assure they give you top performance and durability within their lifetime.

Are you looking for the best duplicate file finder? You must be bothered by the duplicate documents, songs, images or other unwanted files on your. Duplicate files are really annoying. They not only take up your disk space but also leave your folders unorganized. 

The easiest way to get rid of the unwanted files on your computer is to use a duplicate finder. What is the best duplicate file finder? I cannot give you an exact answer. There are a lot of duplicate file finders, scanners, removers and deleters.  It is hard to say which one is the best. But I can give you some tips.

I will list some important features that a good software should have. You can use them to judge which one is the best for you.

Supports A Variety of File Types

A good duplicate file finding software should support various file types such as Words, Excel, images, songs, emails and so on. If a finder can only search for a single file type, you can eliminate it from your selection list.

Multiple Search Criteria

Some file scanners can only search for files by the same name. Actually most redundant files don’t have the same name. You should choose the one that is able to find the files by file size, similar name, file type and other options. A scanner of multiple search criteria can thoroughly scan the files on your computer and enables you to effectively find all the unwanted files.

Scanning Report and Flexibility of Removal

Some programs do not export a search report after scanning and just remove the files directly. They do not even let you select which files to remove. That can lead to serious consequence. Some important files and documents can be deleted mistakenly. You need to make sure the one you use exports a detailed report, and let you know which files are unwanted and should be remove.

Support Other Removable Devices

I also attach great importance to this feature. You should use the one that supports all removable devices like data traveler, iPod, iPhone, Zune, Zip, PSP, Mp4 and so on. It will save you a lot of time if the software can also find duplicate files in your removable devices.

Synchronize Folders

If the scanning tool can also synchronize the files between two folders, it will save you a lot of time and efforts. The duplicate finder that I use can synchronize the files between my computer and removable devices. I don’t need to spend a minutes to copy a file to other folders. This is one of the features I like most.

The above listed features are the most important criteria in selecting a duplicate file remover. Like the one that I use, it has all the features above. It enables me to find and delete all unwanted files on my computer and removable devices.

It brings me a lot of benefits. Now I can easily manage my files and keep the folders in order. You can click here to download the duplicate file finder that I am using. Or you can click here to visit my website to find out which is the best duplicate finder.

If you are someone who cannot afford to stay away from your laptop and would like to carry it whereever you go, you might consider buying a external laptop battery pack for it. Not only do these battery packs provide additional battery power on the move but can also work as a Toshiba laptop battery replacement incase your original Toshiba battery is not working anymore. For people who are always on the run, these laptop battery packs can help to greatly increase their productivity and performance by providing enhanced battery power.

All Toshiba laptop battery packs consist of removable, rechargeable, Lithium ion battery cells (All Toshiba laptop batteries use Lithium ion battery cells). These battery packs can be interfaced with the Power Utility built on Toshiba notebooks helping one to monitor the remaining power. The battery packs have a good design allowing them to attach and detach to the laptop easily and quickly. The quality is similar to that of a battery for Toshiba laptop.

The world of the mobile phone is a confusing one these days, particularly for those wondering how to start a cell phone business. Few things are perhaps as confusing as GSM frequencies and GSM phones that seem to work in some parts of the world but not in others.

Multiple band cell phones and GSM frequencies can be especially confusing for anyone wondering how to start a cell phone business.

So what is the background behind the GSM network?

The GSM network was first suggested by a group of European technicians and policy makers in 1982 and it didn’t take long for consumers and phone makers to adopt the new network after it first emerged in 1991. It wasn’t long before there was growing GSM coverage in an increasing number of countries.

The GSM world grew quickly. There were more than one million subscribers spread over 70 carriers in 30 countries by the end of 1993.

Not only did the new GSM mobile network send and receive all of its information digitally, making it the first 2G mobile phone to be developed it also gave users a great deal of freedom on what they did with it. For the first time they were able to send short written messages to each other for a fraction of the price of a phone call, they could change their carrier and/or go to a different country without getting a new phone.

All they needed to do was to take one GSM SIM card out and replace it with another GSM card and they were in business.

But, as the unknown powers of the world decree, things shouldn’t be that easy and the GSM frequencies set by most of the GSM networks had already been assigned to other purposes by the powers that be.

So, in a situation very similar to TV watchers and people with surveillance systems, a phone that worked in Sussex England wouldn’t pick up anything in San Antonio in the US. Basically it wasn’t a case of one GSM frequency fits all.

As a result, many cell phone makers create cell phones that can work with more than one band with some working with as many as 4 bands.

Still this doesn’t mean there aren’t questions and people are often left asking:
* What is GSM?
* What are the GSM frequencies?
* Why do GSM phones have more than one band?
* Will different frequencies work in different areas?
* How can I check if a phone will work in a particular area?
* How are multiple band phones defined and where will they work?

We’re going to attempt to look at those questions in this article.

What is GSM?
GSM, Global System for Mobile communications (or the Acronym formally known as Groupe Spécial Mobile) is a wireless transmission standard used for mobile phones and, recently wireless modems. GSM and CDMA differ because GSM networks use a SIM card to store all the necessary information to send and receive calls where with CDMA phones everything is kept on the phones.

If you are looking at how to start a cell phone business and you don’t have thousands in working capital GSM mobile phones will probably be a better option than CDMA as they won’t be attached to a particular carrier and don’t require you to be licensed to a particular provider to sell unlocked cell phones.

Another reason to select GSM over CDMA is that it will open up the potential customer base for each phone. As unlocked gsm phones can be used with any GSM networks. To date there is no such thing as an unlocked CDMA phone. When it comes to cell phone plans most providers (especially those in the states) love CDMA phones because it locks their consumers to them.

Why do GSM phones have more than one band?
GSM Phones come with more than one band so that they will work in more than one country as there is more than one GSM frequency and they are not universally transmitted.

As a result, wholesale cellphone manufacturers make GSM and GPRS phones with multiple cell phone bands so that they can work in multiple countries. Most cell phones work on two, three or even four bands. Quad band phones are the most flexible as they can be used all over the world and are often called international phones as a result.

How are multiple band phones defined and where will they work?
Multiple band phones are usually defined by how many GSM frequencies they can operate on and usually come in four different categories, dual band, tri band and quad band. If thinking about how to start a cell phone business it is important to remember the different type of bands as it could mean the difference between your customer getting a high performance phone that they’re happy with and can and them getting a shiny and costly paperweight.

Dual band phone works with two GSM frequencies and, depending on where the phone is made will probably work for the frequencies 900MHz and 1800MHz. These phones are usually less expensive than other types of cell phone and it can be a good way to get a cheap cell phone that will still send SMS MMS and act as a WAP cell phone.

The tri band phone runs on three frequencies and can be used in most countries. This unlocked GSM cell phone is a cheaper option than the quad band phone but safer than a dual band phone.

Quad band phones, or international phones as they are sometimes called, use four bands and can be used anywhere in the world. If you are looking to start a mobile phone business and you wonder what is an unlocked phone guaranteed to sell well and give you the least trouble with customers it will probably be this type of cellphone.

What Are The GSM Frequencies?
Almost all of the world works on the frequencies 850Mhz, 900MHz, 1800MHz, 1900Mhz and in some rare circumstances 400MHz although there are some other frequencies in other locations.

Thankfully too areas where each frequencies work is fairly easy to define in the very general sense (although it always pays to check). So when you’re looking for what areas a cellular phone will work in you should be able to follow a rough guide.

So which areas use GSM 900 and 1800 MHZ signals and which areas use the GSM 850Mhz and 1900MHz frequencies can usually be broken into two groups.

If you are traveling in with your cell phone in Oceania, Africa, Europe, Asia (except for Japan and Korea), the Middle East, Brazil and the Baltic region and looking for roaming networks then mobile network coverage will be either 900MHz, 1800MHz or 900MHz and 1800MHz.

If you are looking for a GSM world phone that will work in the US or South America then you’re better sticking with a wireless cell phone that’ll work on the 850Mhz and 1900MHz bands.

Will different frequencies work in different areas?
With the majority of the GSM world being broken into two main groups (those that take Most of the GSM world is roughly broken up into four main frequencies 900MHz and/or 1800MHz and 850Mhz and/or 1900MHz most unlocked GSM phones will work on one, two or three of the GSM frequencies around the world giving you some level of international roaming on an unlocked phone.

However, you possibly won’t get any joy if for example you take a dual band phone designed for Europe and Asia and then try to use that bluetooth phone in the US.

How can I check if a phone will work in a particular area?
There are two ways to check if a phone will work in a particular area; the first is to get the phone band, which can usually be found on the product description.

If you’re working through how to start a cell phone business and considering phones to stock, it doesn’t matter if you’re thinking about a multimedia mobile, WAP phone or GSM watch phone, the process should be the same. If you are sourcing cell phones from a wholesale supplier or wholesale dropship vendor put the ball into their court. They should have that information on their website or product advertising material for the unlocked cell phone.

Once you’ve got the GSM frequency the GSM phone worked on you can make sure it will work in your area.

If you are looking for a cellphone for yourself this could be as easy as calling your local service provider, or looking it up on sites like GSMworld dot com or worldtimezones dot com.

If you are wondering how to start a cell phone business then your best course of action is to list the frequencies on the description for the GSM cell phone, along with the phone’s other features (like if it is a music phone or it has a good cell phone camera) and tell the person who wants to buy unlocked cell phones from you which parts of the world it will probably work in.

So it looks like cell phone bands and GSM frequencies aren’t that scary after. It’s just a case of knowing where to look and ensuring you’ve got the right phone for the right location.

It is that time of year again when you have to start thinking about buying presents for your friends, family, work colleagues and loved ones. Mind you, it is always that time of year; what with all those birthdays, anniversaries, occasions for impromptu congratulations like the fact that your nephew has just passed his driving test after taking it 5 times. Now that warrants an unusual gifts. And then there are the neighbours who are expecting their first baby any minute now, and of course Great Grandma has made it to 100, so she’ll probably really appreciate a personalised trinket box, or possibly a helicopter ride, depending on what type of granny she is

If, like me, you get into a flat panic at the first sound of Jingle Bells in the supermarket, because it signals the start of the crazy season yet again, have no fear. You can work your way through the present list in a flash by getting every single person a fabulous and unusual gift, something that they will not be expecting and yet something they will be really pleased with.

There is definitely no point in buying a mobile phone for anyone as a gift, as nearly everyone has one already, except me if anyone’s wondering what to buy me. They are all happy with their ring tones, camera facilities and whatever other gizmos they have as features. However, I’m willing to bet that nobody will have a Little Miss Naughty MoPod. What on earth … I hear you cry. This little beauty is a truly unusual gift that is suitable for anyone aged 5 to 105. Purple faced Little Miss Naughty spins and flashes as she interacts with your mobile when it has an incoming call. How can you resist this unusual gifts entertainment and practical value? You will probably decide that you need one for yourself, so be generous and buy an extra one.

For all your friends who spend most of their time on another planet, they will really appreciate this weird and unusual gift of a Mystery UFO. This little gadget will entertain everyone at the office party this year. It appears to float without the help of batteries, magnets or any other force, other than…. Well, only the lucky recipient will know how it works, but it is guaranteed to be a conversation piece, never the less. If you have friends or family members who like to play tricks and are real wind up merchants, they will love to receive unusual gifts from you. What could be more suitable than a remote controlled fake black widow spider? Sit back and watch Auntie Betty leap out of her chair as this life like arachnid creeps silently over her shoulder. Better still, you can really worry the cat with this fabulous toy, but be on your guard. Someone may decide that it’s your turn to be given a shock.

How many people have you got on your gift list that could be classified as senior? I have had senior moments since my 20s, and so a collection of Signs for Senior Moments makes a fantastic gift for almost everyone who manages to forget what whatsisname is called, and exactly where oojimerflip lives. This unusual gift consists of 46 witty but apt signs which you can put on your desk to make you chuckle, especially at those increasingly frequent times when your mind goes blank. For the young, or just the young at heart, a Dennis the Menace catapult kit includes cans and tomato shaped foam balls for safe and friendly target practice. Perhaps this is just what your workmates need after a hard day of dogsbodying or distributing loud orders, depending on how far up the greasy pole they are. Either way, it will put a smile on their face and give them oodles of pleasure as they aim and fire, letting their inner child out for just a while. They will need to keep an eye out for the boss though; otherwise they may soon be catapulted back into the job market.

I expect there are squillions of us who have trouble getting out of bed in the morning. The alarm clock is always within reach and it is too easy to turn over and go back to sleep. Some people even go to the extreme of having more than one alarm clock on the go, perhaps spread around the bedroom to force them out of their nest. The Clocky Clock Alarm Clock is the perfect solution for all those lazy bones sleepy heads who never quite make it to work or school on time. This gizmo bleeps at you, but if you do not respond in time, it goes walk about around your bedroom, still bleeping. Not happy with this alone, it then finds a cheeky hiding place and continues to witter on until you find it. This is bound to get you up and running in no time, and you will earn your gold stars by never being late in the mornings again.

All men have an innate love for gadgets. Even men who aren’t really into techie stuff won’t really complain about getting a cool new gadget as his Christmas present. So the chances of making the gift recipient extremely pleased when he takes out that new gizmo from the Christmas box is definitely bigger than when you put any other stuff in it.

So if you need a Christmas Gift idea or two for men, follow the glimmering lights of today’s coolest gadgets.

But which gadget should you get? There are so many different gadgets out there. How do you know which one will be most appreciated? Well, there’s a perfect match for every man. Here’s a helpful Christmas list guide.

Cell Phone Booster & Cell Phone Repeater FAQ
What to know before you buy a cell phone signal booster / cell phone repeater — What is a cell phone repeater system? A typical system consists of an outside antenna, an amplifier that requires AC or DC power and an inside antenna. The inside antenna is sometimes attached to the amplifier on less powerful systems.

How do cellular phone repeaters work? For incoming calls, the outside antenna, called a “donor” antenna, picks up the signal, boosts it and sends it to the amplifier via a coax cable that connects the two devices. The amplifier boosts the signal again and projects it wirelessly over a given area, through the inside antenna. For outgoing calls the sequence is reversed.

What is a cellular signal? Cell phone signals, like television and radio signals, are radio frequency signals, or waves. Technically, they are electromagnetic waves.

What are cellular frequencies? They are radio frequency levels. The FCC controls the air waves in America and approves different frequency levels for each service provider, or carrier. Typically, 800 MHz to 894 MHz and 1850 MHz to 1990 MHz are reserved for Canada, North America and South America. The 800 MHz and 1800 MHz frequencies are reserved for other continents.

Why can’t I get a cell phone signal inside a building? Radio frequency signals at the cellular level just will not penetrate solid building materials any more dense than, say, sheetrock. They will not penetrate asphalt or concrete shingles, radiant barriers, brick or most wood, even pressboard types. If you can use a cell phone or computer air card in a building, it is likely because it is close enough to the cell phone tower and situated so the signals go through uncovered, non-tinted windows.

If you have a good signal outside, the least expensive solution will be to set a high gain antenna like our 9 dBi Blackcat! on an inside window sill and connect it directly to your cell phone withan adapter made for it.   If your cell phone doesn’t have an external port, your likely solution will be a cellular phone signal booster / wireless repeater system, like the Wilson DeskTop Repeater Kit, which broadcasts signals over an area, so there is no need for an antenna port on your cell phone.

In the US who uses which cellular frequencies? Typically, Sprint and Tmobile use 1900 MHz. ATT, Verizon and Alltel use both 850 MHz and 1900 MHz. Nextel, the walkie-talkie part of Sprint/Nextel uses 806/866 MHz.

What do the cell phone acronyms mean? They refer to various digital code reading technologies for cell phones and computer air cards / data cards. See below:

CDMA: Code-Division Multiple Access (CDMA) is a digital wireless service that transfers data at rates from 40 to 144 Kbps. Unlike GSM, which assigns a specific frequency to each user, CDMA uses every channel to use the full available spectrum.

EDGE: Enhanced Data for Global Evolution (EDGE) is a faster GSM wireless service, that can give data rates up to 384 Kbps. It is based on the GSM standard and uses CDMA.

EV-DO: Evolution, Data Optimized (EV-DO) is a high-speed wireless data connection technology in the CDMA network. This technology allows users access to high-speed internet through portable devices up to 3.1 Mbps.

GPRS: General Packet Radio Service (GPRS) is a packet oriented Mobile Data Service available for 3G cell phones. It provides data rates from 56 up to 114 kbit/s and us used with services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access.

GSM: Global System for Mobile Communications (GSM) is a digital cellular system that uses TDMA, allows a frequency to admit multiple calls and simultaneous channels of data.

HSDPA: High-Speed Downlink Packet Access (HSDPA) is a 3G (third generation) cellular phone data code reading technology in the HSPA family, working with UMTS to have higher data transfer speeds and capacity. Current HSDPA deployments support down-link speeds of 1.8, 3.6, 7.2 and 14.4 Mbit/s.

For operational reasons, service providers may cap this rate to lower rates than the typical maximum 3.6 Mbit/s that most HSDPA handsets support. Voice calls are usually prioritized over data transfer.

IDEN: Integrated Digital Enhanced Network (IDEN) uses TDMA technology to give cellular communication of voice, messaging, digital two-way radio and data transfer.

PCS: Personal communication service (PCS) is a second-generation mobile communications technology also referred to as digital cellular. The digital service, which works over CDMA and TDMA interfaces, operates at the 1900 MHz frequency range. People sometimes think PCS is a SPRINT product, they were, in  fact,  just one of the first companies in America to use it.

UTMS: Universal Mobile Telecommunications System is one of the third-generation cell phone data code reading technologies. It is used in the US and Canada by ATT. Currently, the most common form of UMTS uses WCDMA as the underlying air wave interface. On some smart cell phones and computer air cards the screen may show WCDMA when UTMS is in use. Technically, they would both be in use.

It works GSM interfaces. UMTS, using W-CDMA, supports up to 14.0 Mbit/s data transfer rates in theory (with HSDPA), although at the moment users in deployed networks can expect a transfer rate of up to 384 kbit/s for R99 handsets, and 7.2 Mbit/s for HSDPA handsets in the downlink connection.

W-CDMA: W-CDMA (Wideband Code Division Multiple Access) is a type of GSM digital cellular network. W-CDMA is a wideband spread-spectrum digital technology that achieves higher data speeds and supports more users. W-CDMA using UTMS, supports up to 14.0 Mbit/s data transfer rates in theory (with HSDPA), although at the moment users in deployed networks can expect a transfer rate of up to 384 kbit/s for R99 handsets, and 7.2 Mbit/s for HSDPA handsets in the downlink connection.

Is there a “passive” cell phone repeater? No, even though some people claim to make or sell them. Radio frequencies need power to be pushed, or repeated. That’s what cell phone towers are, repeater towers. They require huge amounts of power (just look at the size of the cables on one),  like radio and television towers. If power was not needed to push the signals, your service provider would need only one tower to serve the world. In other words, if “passive” repeaters worked, there would be no need for “active” ones.

How far will a cell phone repeater broadcast the signal? That depends on a number of things: the current outside signal strength at the place where the cellular phone repeater’s outside antenna will be installed, the gain of that antenna, the amplifier, how much cable will be used and which frequency you want to boost. To compute the coverage area for your application call us and we will do it for you.

How do I know what components to buy for a cell phone repeater? That depends on a number of things: the current outside signal strength at the place where the repeater’s outside antenna will be installed, the gain of that antenna, the amplifier, how much cable will be used and which frequency you want to boost.

To make it easier for our customers, we have assembled cellular phone amplifier / cellular phone repeater kits for both building and mobile use.  The cellular repeater system that will cover the area inside most homes and small offices is the Wilson Model 801245 B.

Can a cellular repeater system boost a weak outside signal? Yes. However, setting up a cell phone amplifier / cellular repeater it is not for the amateur to attempt. It is a normal part of our business, so give us a call if this describes you and your situation.

My next door neighbor can use her cell phone inside, why can’t I? For the same reason you can talk on your cell phone on one side of the street and not on the other. Your house may be blocked from the signal by a tree(s), it may be blocked by her house, it may be lower in elevation and, of course, she may have a different service provider with a tower better located.

Why do I get a good signal in the winter but not in the spring and summer? The trees between you and the tower have leafed out, most likely. You can likely solve this problem by using a pole mounted Yagi antenna elevated to a height that will allow it to “see” the signals it is going after. Usually, between 50%-75% up the tree height, they have thinned out enough to allow you to find a sweet spot. You will then either connect the Yagi directly to your cell phone, if it has the required connection port or air card, connect to an amplifier as part of a wireless repeater system or connect to a Wilson 811210 amplifier that can connect to the devices even if they do not have that are otherwise required for direct connection.

How do I get a cellular signal in my 20th floor office? Three ways, assuming you do have a good signal outside, on the ground. One, set our BLACKCAT! Antenna on the floor, a table, filing cabinet, etc., next to the window and connect it directly to the cell phone, if it has the required connection port, connect the BLACKCAT! Antenna to a Wilson Model 811210 amplifier that can connect to the devices even if they do not have that are otherwise required for direct connection, or use the Wilson Model 801245 DeskTop wireless repeater system that is a kit made specifically for such applications .

Are cellular repeaters legal? Wilson’s are and their’s is the only brand we carry. Legal and FCC approved.

Will audio/visual coax cable work with a cellular repeater? No, it is a 75 OHM resistant cable and cellular uses 50 OHM. It has the wrong connectors and loses too much gain.

What kind of coax cable should be used for a cell phone repeater? LMR400 or 9913.

What is the gain loss of LMR400 & 9913? 3.9 dB @ 850 MHz and 6.5 @ 1900 MHz. RG8X loses about twice the that loss and RG58 loses about 4 times that loss.

How much coax cable can I use

Who makes the best cell phone repeater amplifiers? According to 3rd party verification of test results, Wilson Electronics, for consumer level amplifiers.

Why a Yagi vs. omni-directional antenna for cellular repeaters? Yagi antennas have roughly twice the gain of omni-directional cell phone antennas. Also, all of the Yagi antenna’s gain is pointing in one direction and it’s elements collect and hold the signal better, so it is more efficient. Therefore, more coax cable can be used with a Yagi antenna vs. an omni-directional antenna.

Can multiple inside antenna be used with a cellular repeater? Yes. How many depends on many of the variables used in determining the coverage area of a system with a single inside antenna. We don’t recommend guessing at it. Call us and we will run the formulas for you at no charge – 888-713-1243.

Can multiple service providers be covered with a single cell phone repeater? Yes. It is something we do daily for our customers. The cost is increased with the addition of each service provider. When covering all four major providers, the cost increase can be significant.

Can Nextel be repeated in the same building with other 800 MHz companies? Yes, no matter what you have heard. It requires some knowledge and experience to engineer the system, but it is just as E-Z to install as the others.  We engineer these type applications regularly for our customers.

Is a special repeater needed for the new Sprint/Nextel hybrid cell phones? No. Just use the dual band parallel system and substitute the Wilson Nextel amplifier fo the standard 800 MHz amplifier. The cost is the same.

How can I boost my cell phone signal in my RV wirelessly? You have a number of options. A few are: Use the Wilson Model 901104 chrome mounting bracket to mount the Wilson Model 301101 Trucker Antenna on the back ladder or on a rooftop luggage rack of your RV. Or use the Wilson Model 301189 RV Trucker Antenna, which should be professionally installed at a service center, because it is to be permanently mounted, which requires a hole to be drilled in the RV’s roof.

With either of these antennas you can then either connect directly to the cell phone, if it has the required connection port, or to an air card, connect the BLACKCAT! Antenna to a Wilson 811210 amplifier that can connect to the devices even if they do not have that are otherwise required for direct connection, or use the Wilson Model 80201 mobile wireless repeater system that is a kit made specifically to cover an area about the size of an RV driver/passenger area.

If you prefer to have cell phone and/or air card coverage throughout your large RV, check out our Wilson Model 801245 RV repeater system that was designed by the Director of the Wilson Technical Department and tested by him in numerous RV’s at the Wilson Plant and subsequently by many of our customers.

Now for less than you can set our BLACKCAT! Antenna on the dashboard, a table, filing cabinet, etc., next to the window and connect it directly to the cell phone, if it has the required connection port, or connect it to the Wilson 811210 amplifier that can connect to the devices even if they do not have that are otherwise required for direct connection

What is an NMO cell phone antenna? It is a permanent mount antenna that requires a hole to be drilled into the vehicle’s roof, trunk or hood. It comes in two parts: the “mast”, or top part and the “mount” or bottom part. The mast and mount screw together above and below the surface to hold both securely. The mount of Wilson’s NMO cellular antennas come with 14′ of RG58 coax cable with a FME Female connector attached. An example of a NMO cell phone antenna is our Wilson Model 304203.
