CDMA2000 (Code Division Multiple Access 2000) is a 3G mobile communication standard, derived from CDMA and CDMA1X network and the radio interface of IMT-2000 standard.  It is approved by the International Telecommunication Union ITU and is considered as the extension of 2G CDMA1X standard.

As a new technology, CDMA2000 evdo dual band router is rapidly sweeping the world and has occupied 20% of the wireless market. Until 2012, more than 156 counties have adopted the global CDMA2000 technology and own over 256 million users. Dozens of global OEM manufacturers launched EVDO mobile intelligent terminal.

CDMA2000 is an upgraded version of CDMA. CDMA is the second generation communication protocol standard, CDMA2000 is the third generation, that is, the 3G standard. 3G's advantage is faster speed internet access, video phone, etc

The advantages of 3G CDMA2000 routers

Times are changing very fast, now we have entered into the information age. Various kinds of mobile phones emerge one after another, most of the mobile phones now are touchscreen-based smartphones. We all know that surfing the Internet with your mobile phones will consume traffic. Since wireless routers have been invented, where there is a 3G CDMA2000 router, we can connect it with our mobile phones after turning on the "WI-FI" function. The wirless net speed is far faster than that of mobile phone traffic and it is free of charge. It seems that 3G wireless routers have a lot of advantages, then how much do you know them?

Introduction of the functions of 3G CDMA2000 routers:

1. WIFI technology has combined with 3G technology perfectly, high-speed surfing has been achieved completely.

2. They have net card modules inside, you can insert the SIM cards into them and they will dial automatically, they are easy to operate.

3. The linear transmission distance is 300 meters outdoor and 20-50 meters indoor.

4. They are small and portable, people can use 3G anywhere and at any time.

5. They can support more than 10 computers surfing the Internet simultaneously, both wire net and the wireless net can be used.
