Booster Choices: Dual Band CDMA (Model BST800): Most CDMA handsets are capable of digital PCS band, digital Cellular band and analog communication. CDMA coverage is normally deployed in major cities using the PCS (1900 Mhz band) and cities are normally covered with large numbers of towers and repeaters. Coverage is usually very good. Because of the large numbers of towers and their close proximity to handsets, towers (which control the transmit power of the handset) rarely command a handset to transmit at maximum power, therefore using a PCS 1900 Mhz booster on a dual-band cell phone would be of no benefit because the tower would command the handset to reduce power when the booster is connected. CDMA coverage in non-urban areas is usually in the Cellular (800 Mhz band) and this is where towers are spaced at greater distances from each other. This is also the band that analog is on. This is the band where spotty coverage exists and using a Cellular 800 Mhz booster is advisable. A dual band CDMA phone with Analog capability used with a Cellular 800 Mhz booster will get coverage in as many places as possible and have the best coverage of any CDMA phone/booster combination. When using a Sprint phone that you have set to home only and use this phone only in the PCS band, then a PCS 1900 Mhz booster for CDMA phones is your only and logical choice whether it used in a city or in urban areas. Chapter 15 covers this in more detail. |
