SkyLinx GSM

Delivering Profitable GSM/3G Access to Underserved Communities



FULLY INTEGRATED, LOW COST GSM/3G INFRASTRUCTURE SUPPORTING MOBILE APPLICATION SERVICES

ViaSat enables mobile network operators (MNO) to deliver GSM/3G voice, messaging, application and data services to underserved communities. Featuring a fully integrated cellular and satellite backhaul network allows MNOs to easily extend their existing networks to address underserved areas or create greenfield networks. For the first time, mobile operators are equipped to deliver profitable and sustainable services to underserved communities using a distributed architecture model connecting low-power remote VSAT terminals via lowbandwidth satellite links. The system interoperates with existing GSM/3G management systems and facilitates roaming and MNO inter-working.


SUPPORTED SERVICES

Services available to underserved communities include:
» SMS messaging – supports mobile banking applications
» Data – 3G/GPRS/EDGE
» Support for USSD services


BUSINESS BENEFITS

» Expanding geographic coverage increasing the number of urban and rural subscribers
» Very low operational costs – sustainable infrastructure
» Bringing support of e-initiatives to underserved areas
» Immediately deliver essential services to off-grid sites
» Ideally suited to micro-financing and universal service obligations

When compared to the cost of extending mainstream cellular networks using fiber, microwave or traditional VSAT back haul, this complete end to end solution significantly reduces both capital and operating costs.
