Chapter 12 Interfaces • You can set the 3G device to connect only to the home network, which is the network to which you are originally subscribed. • You can set the 3G device to connect to other networks if the signal strength of the home network is too low or it is unavailable. Aside from selecting the 3G network, the 3G card may also select an available 2.5G or 2.75G network automatically. See the following table for a comparison between 2G, 2.5G, 2.75G and 3G of wireless technologies. Table 69 2G, 2.5G, 2.75G, 3G and 3.5G Wireless Technologies NAME TYPE MOBILE PHONE AND DATA STANDARDS GSM-BASED CDMA-BASED DATA SPEED 2G Circuit- GSM (Global System for Mobile Interim Standard 95 (IS-95), the first CDMA- Slow switched Communications), Personal Handy-phone based digital cellular standard pioneered by System (PHS), etc. Qualcomm. The brand name for IS-95 is cdmaOne. IS-95 is also known as TIA-EIA-95. 2.5G 2.75G Packetswitched Packetswitched GPRS (General Packet Radio Services), HighSpeed Circuit-Switched Data (HSCSD), etc. Enhanced Data rates for GSM Evolution (EDGE), Enhanced GPRS (EGPRS), etc. CDMA2000 is a hybrid 2.5G / 3G protocol of mobile telecommunications standards that use CDMA, a multiple access scheme for digital radio. CDMA2000 1xRTT (1 times Radio Transmission Technology) is the core CDMA2000 wireless air interface standard. It is also known as 1x, 1xRTT, or IS-2000 and considered to be a 2.5G or 2.75G technology. 3G Packet- UMTS (Universal Mobile Telecommunications CDMA2000 EV-DO (Evolution-Data Optimized, switched System), a third-generation (3G) wireless standard defined in ITUA specification, is originally 1x Evolution-Data Only), also referred to as EV-DO, EVDO, or just EV, is an sometimes marketed as 3GSM. The UMTS evolution of CDMA2000 1xRTT and enables uses GSM infrastructures and W-CDMA high-speed wireless connectivity. It is also (Wideband Code Division Multiple Access) as denoted as IS-856 or High Data Rate (HDR). the air interface. 3.5G Packetswitched HSDPA (High-Speed Downlink Packet Access) is a mobile telephony protocol, used for UMTS-based 3G networks and allows for higher data transfer speeds. Fast A. The International Telecommunication Union (ITU) is an international organization within which governments and the private sector coordinate global telecom networks and services. To change your 3G WAN settings, click Configuration > Network > Interface > Cellular. Note: Install (or connect) a compatible 3G USB to use a cellular connection. Note: The WAN IP addresses of a ISG50 with multiple WAN interfaces must be on different subnets. 252 ISG50 User's Guide
