Cel-Fi is a Smart Signal Booster created by Nextivity Inc. Cel-Fi DUO+ Signal Booster For T-Mobile is available for outright sale. This T-Mobile 4G LTE Signal Booster Duo supports non Wi-Fi calling capable devices. Therefore, Wi-Fi Calling capable phone is not required. It requires a minimum one bar of 3G, 4G HSPA+, or 4G LTE indoor signal and a 3G, 4G HSPA+, or 4G LTE device on T-Mobile network. It works with all 3G/4G UMTS or 4G LTE capable handsets compatible with T-Mobile network. They can be a T-Mobile or Bring Your Own Device (BYOD) phone. It also supports the new T-Mobile 700 MHz (Band 12) frequency. E911 location is determined by standard cellular triangulation. It is perfect for those that have atleast 1 bar of 3G/4G UMTS or 4G LTE signal coverage, and does not have or want to use high-speed Internet for boosting signal.
In general, similar to a cellular repeater, Cel-Fi devices have been specifically designed to improve mobile cell-phone reception indoors for data and 4G, in addition to eliminating in-building dead zones. With its smart antenna technology, the Cel-Fi system locates the strongest available signal then maximizes the signal boost to users of smart phones.
Cel-Fi covers spaces not covered before and solves the problem of low data throughput, poor voice quality, and dropped calls caused by weak cellular indoor signal. Cel-Fi optimizes cellular coverage, thus making it the perfect solution for multi-story homes, small businesses and other enterprise environments, boats and vehicles. Operating in spaces of up to 200,000 ft.², Cel-Fi has been created with technology that makes it network safe because it deters interference with mobile operator networks.
Cel-Fi automatically adjusts to changing network conditions. It provides optimal coverage and is installer friendly. Available in over 100 countries and approved for use on 200 carriers, Cel-Fi solutions range from enterprise level right down to plug-and-play as T-Mobile Cel-Fi DUO+ Signal Booster listed above, always providing the industry's highest Max Gain.
When it comes to performance and value per square footage of coverage, Cel-Fi delivers a low cost per dB of gain. No longer must you tolerate dropped calls in your home or office because with a Cel-Fi signal booster you will achieve greatly enhanced cellular connections in addition to boosted data speed.
Unlike a standard repeater, the Cel-Fi system was designed to be network friendly, provide maximum coverage, and be easily installed by end user. With Cel-Fi, there are two wireless devices that work together to increase mobile broadband connectivity throughout a building – the Window Unit and the Coverage Unit. The signal is received by the Window Unit, which is relayed to the receiver, which in turn cleans, converts, and amplifies it.
How Cel-Fi Works.
Cel-Fi mobile repeaters have been designed specifically to distribute a mobile signal within a building without interfering with the mobile network. The two boxes that comprise the Cel-Fi system are the Window Unit and the Coverage Unit. The Window Unit connects with the mobile base station, amplifying the signal, then passing the signal to the Coverage Unit through a wireless link. The mobile signal is then disbursed within the building to mobile devices via the Coverage Unit.
What makes the Cel-Fi repeater system so unique is its ability to maximize indoor coverage. The Window Unit and Coverage Unit can be up to 30 meters apart, and the further apart these two units are, the better the indoor coverage will be.
Cel-Fi Offers Improved Mobile Coverage Indoors and Increased Mobile Data Speeds.
All that is required for the Cel-Fi to provide indoor coverage is a location in your home that achieves a minimum of one bar of 3G or 4G signal. The number of walls in the home and the mobile signal strength at the Window Unit are two factors that determine indoor coverage. Cel-Fi means you no longer need to go outside your home to make a phone call.
Anyone who has endured the frustration of trying to access the Internet will understand just how annoying slow Internet speeds can be. With Cel-Fi, the mobile signal will be amplified and your data speed will increase dramatically. There will be no more frustrations with social networking, video, Internet, and email.
Cel-Fi Means Extended Mobile Phone Battery Life.
When mobile phones are used in poor signal areas they use a lot more battery power because, attempting to boost the poor signal, the phone will adjust its internal power in compensation. With Cel-Fi, you will have a high indoor mobile signal, resulting in longer battery life, which means longer for you to browse the Internet, check Facebook, and so on.
Improved Voice Quality with Cel-Fi.
The quality of any voice call is typically determined by the signal strength of the phone and any nearby interference. Therefore, with no interference and full signal strength inside the home, Cel-Fi will deliver clear voice quality for your mobile devices.
Decreased Radiation to Mobile Users.
Research shows that when your phone is closest to your body and using maximum power, mobile radiation is at its greatest. Therefore, when you use Cel-Fi to increase indoor signal strength, your phone is not being pushed to its limits, resulting in decreased radiation for the user.
When Nextivity created its Cel-Fi Smart Signal Booster the aim was to develop a plug-and-play solution that resolved the challenges incurred when users experience ineffective indoor cellular coverage. Typically, customers experience no issues at all with Cel-Fi installation. However, there are always going to be instances where things don't go according to plan. Let us help to ensure your installation works perfectly - Understand the concept and you will know how to install it correctly.
The Cel-Fi installation process could be described as the creation of a bubble, with the center being the Coverage Unit and the outside edge of the bubble being the Window Unit. The aim with Cel-Fi is to place these two units as far apart as possible in order to create as big a bubble as possible, but without losing any signal between the two.
Below we have listed some handy tips for users who may need a little extra help in achieving the very best results:
- Referring to the Cel-Fi Duo, Cel-Fi Pro, The First-Generation RS1 and the Second-Generation RS2, the Window Unit reveals a number of bars. This number refers to the amount of signal you're receiving from your carrier's network.
- There's a numeric indicator in the display on the Coverage Unit which shows the relative size of the bubble. The higher the number the bigger the bubble.
Please Note: The information on the Cel-Fi Pro is shown as a number of radiating semi-circles; whereas it appears as a number between 1 and 9 on all other models.
- If the Coverage Unit shows a low number, this is irrelevant to how many bars are showing on the Window Unit. Instead, it tells you how far apart the devices can be placed. If you place them too close together they could interfere with each other, while the connection could be lost if they are placed too far apart. Keep in mind that the higher the value, the bigger the bubble; meaning that it is better to have a higher indication on the Coverage Unit.
- If there's a specific area of your home that you require coverage, then the Window Unit should be placed where you achieve the most bars on the Coverage Unit within the targeted area. This is the area displaying the strongest coverage.
If you're still experiencing problems with your Cel-Fi installation, please don't hesitate to contact our knowledgeable support team. We're here to help, and our aim is to ensure that all installation issues are resolved as quickly as possible.
