In the U.S., Code Division Multiple Access (CDMA) is a popular cellular technology that's an alternative to GSM. CDMA uses Spread Spectrum Technology (SST), which allows a unique code to be attached to each conversation and to spread conversations across wide segments of the cellular broadcast spectrum. Each receiver decodes on the same frequency segment as the sender. Because multiple signals can be transmitted over the same spectrum, CDMA allows many more possible conversations when compared to other cellular technologies. Sprint PCS and Verizon Wireless use CDMA. 7.4.1 Connecting via Express NetworkThe Motorola v120e (Figure 7-10) is a data-capable phone that can connect to a CDMA2000 1xRTT network. Although it doesn't have Bluetooth (at the time of this writing, few Bluetooth-enabled CDMA phones were available), you can connect it to your Mac using a USB cable and get online at speeds faster than those currently available with a GPRS phone.
