Communication

The F5521gw Mobile Broadband Module keeps end-users up-to-date by
providing them the best available mobile service wherever they are.
F5521gw is a dual mode device, able to connect via UMTS/HSPA and
GSM/GPRS/EDGE. The user will remain connected without having to think
about what system is being used – the handover between two systems and
network technologies is automatically managed by F5521gw. F5521gw comes
in one hardware version supporting both quad-band UMTS (Band I, II, V, VI
and VIII) and quad-band GSM/GPRS/EDGE (850/900/1800/1900 MHz).

Network Technologies

3.1.1 3G
3G (third-generation) services combine high-speed radio access with IP-based
(Internet Protocol) services. This not only means fast mobile connection to the
Internet, but also a totally new way to communicate, access information,
conduct business, learn and be entertained.
Compared to 2G mobile networks, 3G significantly boosts network capacity, a
much needed feature in densely populated areas. This means that operators
are able to support more users and offer them more sophisticated services.
3.1.1.1 HSPA Evolution
HSPA (High Speed Packet Access) Evolution enables downlink speeds up to
21 Mbps (HSDPA cat 14) and uplink speeds up to 5.76 Mbps (HSUPA cat 6).
Higher order modulation results in higher possible speeds in the network.
3.1.1.2 HSPA
HSPA is available in all developed 3G markets. With its HSDPA solution,
F5521gw is capable of downlink speeds of up to 14.4 Mbps and uplink speeds
of up to 5.76 Mbps. This, together with its antenna diversity technology, gives
F5521gw a fast and reliable connection.
3.1.1.3 WCDMA
The initial implementation of 3G networks enables Internet or corporate
network access at bidirectional data rates of up to 384 kbps.
