2G – General Packet Radio Service (GPRS) Support Node

iCore® 2G – General Packet Radio Service (GPRS) Support Node

The iCore 2G is a compact, carrier-grade General Packet Radio Service (GPRS) support node facilitating GPRS and EDGE packet data access. The platform can be deployed as a Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN) or both. Designed to cost-effectively introduce data services to a 2G network, this node fits into the iCore 2G-3G-4G product portfolio as shown on the left. This architecture enables operators to evolve to future generations through software plug-ins, increasing flexibility and reducing cost of upgrades.

As with all Tecore products, the GSN is fully compliant with the applicable 3GPP standards, is available on a standalone basis on a range of carrier-grade hardware platforms, and can also be integrated as a blade in a complete iCore network system. The iCore 2G GSN has been deployed in standalone and roaming networks connecting with infrastructure and devices from the industry’s leading vendors.

Target markets include:

Rural network operators introducing data services or needing to add packet data support to maintain roaming agreements
Remote islands, villages, and oil fields
Operators in developing markets offering data services
Rapid deployment systems for emergency communications restoration
Transportable networks including vehicle-mounted, airborne and maritime systems
Government and military data applications
Enterprise and university campuses
