As society gets more entrenched in the mobile world, we have to learn a whole new lingo just to keep up. In a previous blog post we talked about “Gs” such as 2G, 3G and 4G. The G as you recall stands for Generation, with 4th generation networks being the latest.
You may wonder why we have different Cel-Fi products for the market. The answer is simple. Cel-Fi is designed to work with a specific Generation of mobile device. It also has to support the right type of Mobile Technology and operate in specific Band(s) for your carrier.
To make it easier to decipher some of this mobile lingo, here’s a handy “cheat sheet”.
Let’s start with the type of Mobile Technology. In North America, mobile technologies can be grouped into two basic camps: GSM (Global System for Mobile Communications)-based or CDMA (Code Division Multiple Access)-based.
GSM-based technologies include GSM, EDGE, UMTS, HSPA. They’re offered by companies such as AT&T and T-Mobile. Most of Europe also operates with GSM-based technologies.
CDMA-based technologies include CDMA, CDMA2000 and EVDO and are used by companies such as Sprint and Verizon.The good news is that most phone companies are getting ready to come together and implement a common mobile technology called LTE (Long Term Evolution).
A band that doesn’t involve music…
Your mobile device is designed to support a specific frequency Band(s). The bands are numbered starting with 1 and move up systematically. Band 1, for instance, operates in the 2100 MHz range and is used throughout Europe and much of the rest of the world except for the USA. In the USA most operators use Band 2 and 5, except for T-Mobile and a couple of smaller operators who used Band 2 and 4.
So that in a nutshell is why there are different versions of Cel-Fi. Our advanced technology is designed to be carrier specific so that it will automatically work based on your combination of Generation, Mobile Technology and Band. We did this so you would never have to worry about the details. All you have to think about is how much you are going to enjoy the faster data rates and better coverage.
How important are faster data rates to you?
