Cellular Data Transmission Speeds with RouteRider LE

August 2005

In the 1980’s cellular technology was analog based. General business use was essentially just voice communication. This was the first generation (1G) of cellular technology.

From 1990 to 1995 digital communication began with some data transmission at less than 20Kbps. CDMA and GSM made their debuts, this was 2G or second generation cellular technology.

The years 1995 to 2000 saw the beginning of GPRS and 1xRTT technologies, 2.5G, with data speeds at dial up rates of 30Kbps to 90Kbps.

During the last 5 years EDGE (2.5G) and UMTS and 1XEV-DO (3G) have evolved with the 3G networks running at data speeds anywhere from 144Kbps to 2Mbps.

Brief History of Cellular Technology

Cellular Formats GSM (Adopted in Europe, lastly in North America)

Cingular (AT&T Wireless), T-Mobile GPRS a 2.5G technology

30Kbps to 40Kbps data rates real world (50Kbps) EDGE a 2.5G technology

90Kbps data rates real world (384Kbps) UMTS a 3G technology

2Mbps but actual rates may be 300-400Kbps HSDPA a 3G technology (an enhanced UMTS)

14.4Mbps CDMA (Adopted in North America)

Sprint (Nextel), Verizon 1xRTT is a 2.5G technology 1xEV-DO/1xEV-DV

DO Data Only Speeds of 2.4Mpbs DV will enable data and voice
