2 Introduction
The GW1000 Series router can contain either a 3G or 4G wireless modem. The modem
together with a SIM card establishes a WAN connection to the Internet or private
network.
3G is the third generation of mobile phone standards and technology. It is based on the
International Telecommunication Union (ITU) family of standards under the International
Mobile Telecommunications programme, IMT-2000.
3G and 4G technologies enable network operators to offer users a wider range of more
advanced services while achieving greater network capacity through improved spectral
efficiency. Services include wide-area wireless voice telephony, video calls, and
broadband wireless data, all in a mobile environment.
Data bearers are frame protocols that transport data streams. The GSM (3G) modem
supports GPRS, EDGE, HSDPA, HSUPA, UMTS and CSD. The 4G modem supports 4G
frequencies and fails over to 3G, GPRS and EDGE technologies.
2.1 4G LTE
4G LTE is the fourth generation of mobile communication technology standards. It is a
successor to 3G and provides greater bandwidth.
2.2 GPRS
GPRS (General Packet Radio Service) uses packet-switched technology to transmit small
bursts of data. The 3G or 4G modem on the GW1000 Series supports multi-slot class 6,
which allows a maximum data rate of 384Kbps class 3. The maximum data rate available
to the 3G or 4G modem depends on provisioning by the network operator.
2.3 HSPA+
High-Speed Packet Access + is an improvement on UMTS with achievable download
speeds of 21Mbps.
2.4 HSDPA
HSDPA (High-Speed Downlink Packet Access) uses circuit-switched technology to
transmit data at speeds of up to 7.2Mbps.
2.5 HSUPA
HSUPA (High-Speed Uplink Packet Access) is a 3G mobile protocol with uplink speeds of
5.76Mbps.
2.6 UMTS
UMTS (Universal Mobile Telecommunications System) is a third generation technology
providing higher transfer rates.
