7 GSM Communication (AT&T
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.
7.1

HSUPA

HSUPA (High-Speed Uplink Packet Access) is a cellular technology which most
closely resembles a broadband synchronous connection. The upload and
download speeds are maximized to provide a faster throughput, reaching speeds
up to 2.0 Mbit/s for the uplink and 7.2 Mbit/s for the downlink. Please check with
your network provider on the availability of HSUPA.
7.2

HSDPA

HSDPA (High-Speed Downlink Packet Access) is a cellular technology allowing
for higher data transfer speeds. In HSDPA mode of operation, max speeds are
up to 7.2 Mbit/s in the downlink and 384 kbit/s in the uplink. HSDPA uses
Adaptive Modulation and Coding (AMC), fast packet scheduling at the Node B
(Base Station) and fast retransmissions from Node B (known as HARQ-Hybrid
Automatic Repeat Request) to deliver the improved downlink performance vs.
UMTS and EDGE.
HSPDA (and HSUPA) falls back to UMTS, EDGE or GPRS (in order of
precedence). This feature allows you to have seamless connectivity no matter
where your ICX35-HWC is located.
7.3

UMTS

UMTS (Universal Mobile Telecommunications System) supports up to 1920 kbit/s
data transfer rates, although most users can expect performance up to 384
kbit/s. A UMTS network uses a pair of 5 MHz channels, one in the 1900 MHz
range for uplink and one in the 2100 MHz range for downlink.
7.4

LTE

Long Term Evolution (LTE) commonly referred to at 4G LTE, is based on the
GSM/EDGE and UTMS/HSPA network technologies, increasing the capacity and
speed using a different radio interface together with core network improvements.
LTE offers the highest link rates currently available.
