ViaSat to Provide Airtel Enterprise Services With LinkStar Satellite Network for Satellite Services in India

Posted on: Wednesday, 17 August 2005, 12:00 CDT

NORCROSS, Ga., Aug. 17 /PRNewswire-FirstCall/ -- ViaSat is supplying a LinkStar(R) broadband network to Airtel Enterprise Services, the enterprise arm of India's leading telecom group, Bharti Tele-Ventures Ltd. (BTVL), for shared-hub satellite communication services in India. Airtel is planning to offer a range of networking services, from low-rate point-of-sale data to broadband virtual private networks and Internet access. LinkStar VSAT options for network access and bandwidth management make it an efficient choice for all types of traffic. The Airtel network includes a LinkStar hub installation in Bangalore and an expected delivery of 5,000 remote VSATs during the first year.

The Airtel shared hub services will cater to many customer segments. Bank ATMs, stock brokers, and gaming applications need fast access and low-rate transactional data. Enterprise customers look for high-speed, secure client-server applications that extend their corporate networks for virtual private networks, enterprise-wide resource or customer management systems, and Internet access. The LinkStar satellite network includes enterprise-level features such as DiffServ QOS and multi-label protocol switching support that enable many customers to share a single VSAT hub, while keeping their data separate and secure from other users. ViaSat dynamic bandwidth allocation increases or decreases data rates on-the-fly to adjust to each customer and use the available satellite bandwidth in the most efficient way.

"We have chosen ViaSat because they have number of advanced VSAT technologies and a mature in-country support operation," said Airtel Enterprise Services CEO, Mr. Rajiv Sharma.

Ku-band transponders on the SES Americom AAP-1 satellite will carry the network traffic. Data rates will begin at 256 and 512 kbps on the inbound and 5 Mbps on the outbound (hub to remotes). The system can support up to 3.3 Mbps uploads from remote sites and up to 45 Mbps downloads from the hub.

The advantages of the LinkStar VSAT system can be traced to its versatility. The system is cost-effective for a full spectrum of applications, from low speed, quick-turnaround retail transactions to broadband multimedia applications. The LinkStar system can operate in a proprietary configuration from ViaSat or according to the DVB-RCS international standard.
