This ensures that the call travels exclusively through the least cost route, and also ...
Able to produce a reasonable call with lower signal (cell phone reception) levels. Uses soft handoff, reducing the likelihood of dropped calls. IS-95's variable rate voice coders reduce the rate being transmitted when speaker is not talking, which allows the channel to be packed more efficiently. Has a well-defined path to higher data rates.
GAN often provides lower rates when roaming internationally. [ 16 ] GAN is currently the only commercial technology available [ 17 ] that combines GSM and 802.11 into a service that uses a single number, a single handset, a single set of services and a single phone directory for all calls.
