The CDMA wireless network
This is the worldwide infrastructure providing the radio coverage that allows you to
stay connected. Made up of radio towers and a variety of network switches,
routers, and servers, the network is an interconnection of many service providers.
Note: More information about CDMA networks is available on the CDMA
Development Group web site, www.cdg.org.
There are CDMA networks that operate in the frequency bands supported by the
Modem throughout North America and parts of Latin America, Asia, and New
Zealand. However, each service provider operates a network that covers a limited
geographical area within the overall CDMA coverage area.
Note: Some service providers have coverage maps on their web sites.
