Cellular Technology Definitions
Many GSM Networks have been upgraded to support HSUPA. GSM Networks use
SIM cards which are smart cards containing the account holder's details. A SIM can
generally be moved from one device to another allowing for account flexibility.
CDMA (Code Division Multiple Access) is the cellular technology used by Verizon in
the United States. The ICX35-HWC is certified by Verizon. To provide backward
compatibility and seamless connections in a wider range of locations, the ICX35-
HWC will fall back to 1x when EV-DO is not available.
1x
1x provides a digital cellular telephony system and can provide wireless Internet
access at speeds between 60 and 80 kbps, with bursts up to 144 kbps.
EDGE
EDGE (Enhanced Data rates for GSM Evolution) provides end-to-end packet data
services with an enhanced connectivity building on GPRS technology and using the
established GSM networks. EDGE provides higher transmission rates and better
transmission quality for data than GPRS. EDGE can carry data at speeds typically up
to 384 kbit/s in packet mode.
When EDGE is not available, your ICX35-HWC will fall back to GPRS for the
connection to your cellular provider to provide continued connectivity.
EV-DO
EV-DO (Evolution Data Optimized) provides a broadband-like cellular data
connection that is 10 times faster than 1x/CDMA service. With the high-speed
connection, users can experience faster downloading when accessing the Internet
and retrieving e-mails, including large attachments and other bandwidth-intensive
applications. EV-DO is often referred to as Mobile Broadband and Cellular
Broadband.
EV-DO revision A is an enhancement on the original revision 0 adding expanded
upload capabilities and a more robust connection overall. In addition to increasing the
downlink speed, revision A also increases the uplink speed. In addition, it is
backwards compatible and automatically connects with existing and broadly
deployed EV-DO Rev. 0 and 1x networks ensuring reliable and pervasive
connectivity.
GPRS
General Packet Radio Service (GPRS) is packet-switched with many users sharing
the same transmission channel, but only transmitting when they have data to send.
This means that the total available bandwidth can be immediately dedicated to those
users who are actually sending at any given moment, providing higher utilization
where users only send or receive data intermittently. GPRS provides speeds of 30-70
kbps with bursts up to 170 kbps.
