GSMnet (3G)

SiRRAN Communications Ltd provides world leading 2G, 2.5G, 2.75G, 3G & 3.5G mobile solutions which range from tactical network deployment to advanced global network switching infrastructure, these solutions seamlessly link the full range of our solutions in a highly secure and resilient environment.

Traditional 3G core network infrastructure has been physically large, expensive and heavily engineered. This has made it difficult to justify where either tactical units or low entry cost standalone 3G capability is demanded.

The SiRRAN all-IP 3G technology integrates the essential elements of 3G core network infrastructure, eg RNC, MSC & HLR/AuC, and provides fully functional CS and PS/HSPDA services on a simple, easily deployable single system platform with SIP interconnect.

The SiRRAN GSMnet product range allows its Customers to leverage the availability of femtocell technology and extend 3G coverage to otherwise isolated areas, allows military and emergency aid agencies to rapidly deploy a cellular network.

SiRRAN has a commercially available 3G products, this groundbreaking core network infrastructure solution offers the significant benefits of 3G cellular voice and data coverage but engineered to run in the smallest footprint and most cost-effective package ever seen for 3G CN infrastructure

GSMnet (3G) brings together the standard 3GPP architectural elements of RNC, MSC and HLR/AuC into a single processing platform, suitable for standalone femtocell market trials, small government or commercial 3G deployments and rural networks. CS voice calls are supported between handsets and over SIP to a separate SIP server if required, and PS/HSDPA data services are supported to the local LAN.

GSMnet (3G) software is available on a range of hardware platforms, from an embedded to higher capacity rack servers. A functional CS and PS UMTS core network can be operated without the need for any other expensive and physically large 3rd party hardware or software
