Expected Deployment
|
GSM
|
Circuit-switched data based on the standard GSM 07.07
|
9.6kbps or 14.4kbps
|
Available worldwide
|
|
High-speed circuit-switched data (HSCSD)
|
28.8kbps to 56kbps service likely
|
Limited deployment 1999 and 2000 as many carriers will wait for GPRS
|
|
General Packet Radio Service (GPRS)
|
IP and X.25 communications over kbps
|
Trial deployments in 2000, rollout of service 2001
|
|
Enhanced Data Rates for GSM Evolution (EDGE)
|
IP communications to 384kbps. Roaming with IS-136 networks possible
|
Trial deployment in 2001, rollout of service 2002
|
|
Wideband CDMA (WCDMA)
|
Similar to EDGE but adds 2Mbps indoor capability. Increased capacity for voice
|
Initial deployment in 2002 or 2003
|
IS-136
|
Circuit-switched data based on the standard IS-135
|
9.6kbps
|
Some may offer, but not expected on widespread basis beacuse key carriers already offer Cellular Digital Packet Data (CDPD)
|
|
EDGE
|
IP communications to 384kbps. Roaming with GSM networks possible
|
Initial deployment 2002 or 2003
|
|
WCDMA or Wideband TDMA (WTDMA)
|
Similar to EDGE but adds 2Mbps indoor capability
|
No stated deployment plans
|
CDMA
|
Circuit-switched data based on the standard IS-707
|
9.6kbps or 14.4kbps
|
Available by some carriers now
|
|
IS-95B
|
IP communications to 64kbps
|
Expected in Japanese markets by early 2000
|
|
CDMA2000-1XRTT
|
IP communications to 144kbps
|
Trial deployment in 2001, rollout of service 2002
|
|
CDMA2000-3XRTT
|
