Acronyms

1G		First Generation
1XRTT		A spectrum migration technology for existing IS 95 bands and systems. 1XRTT phase employs 1.25 MHz of bandwidth and is expected to provide up to twice the Radio Frequency (RF) capacity of current technologies. It is expected to support speeds of 144 Kbps for stationary and mobile applications.
IS95		Interim Standard 95
2G		Second Generation
3G		Third Generation
3XRTT		A spectrum migration technology for existing IS95 bands and systems. 3XRTT will support all channel sizes (6x, 9x, and 12x) and will use 5 MHz of bandwidth. It is expected to allow up to 2 Mbps for stationary applications
