1.2 GW1000M Series router overview and features 
The GW1000M 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.
