TerreStar: I-HSPA for Satphones

Posted by Sam Churchill on

Nokia Siemens Networks announced today it has been selected by innovative satellite phone company TerreStar Networks, to deploy its Internet-HSPA solution for the TerreStar all-IP integrated satellite and terrestrial wireless communications system.

This will be Nokia Siemens Networks’ first commercial I-HSPA network deployment, a technology that Nokia Siemens helped pioneer.

Their Flexi WCDMA Base Station uses an Internet-High Speed Packet Access (I-HSPA) architecture, which eliminates legacy circuit-switched technology. Optimized for native IP applications, including voice and data, I-HSPA is the only commercially available all-IP solution, and is optimum for edge deployment within TerreStar’s MSS service, says the company.

“I-HSPA still isn’t a replacement for WiMAX, not providing the bit-per-hertz efficiency of the OFDMA technology, but it’s not intended to be”, said Mark Slater Nokia’s VP of sales, in Telephony Magazine. Nokia, in fact, is straddling both sides of the fence, building a WiMAX portfolio in parallel with its UMTS (3G) cellular portfolio.

Devices normally connect through a base station and then are routed through specialized cellular gear before finally hitting the Internet. I-HSPA eliminates much of that cellular gear, allowing the device to connect directly to the Internet through a base station. Smooth handoffs between ajoining cell sites is said to be the downside.

TerreStar Networks, a satellite phone company, will leverage Nokia Siemens Networks’ I-HSPA technology as the foundation for development of their LTE (Long Term Evolution) services.

“Today’s announcement marks a series of firsts for Nokia Siemens Networks: we’re deploying the first I-HSPA network, we’re delivering the first satellite band Flexi, and we’re deploying the first direct tunnel packet core,” said Sue Spradley, Head of North America, Nokia Siemens Networks. “We’re truly excited that TerreStar has chosen the advantages of Nokia Siemens Networks’ state-of-the-art solutions to be incorporated into their architecture enabling the first ever all IP-based 4th Generation Network Application environment.

When TerreStar’s network is deployed in 2008, the company will provide universal access and tailored applications to millions of users throughout North America via mass market commercial wireless devices and spot beams.

TerreStar will serve a range of customers including homeland security agencies, public safety agencies, rural communities, and wireless carriers. Terrastar is also unique in that it uses ATCs, or repeaters, that utilize the Mobile Satellite Spectrum around 2.1 GHz. TerreStar expects to be the first to offer customer-designed products and applications over a fully optimized 4G IP network.

The great majority of cellular carriers world-wide use variants of GSM technology (with over 2 billion connections), while the incompatible CDMA technology, preferred by Sprint and Verizon in the United States, as well as major carriers in South Korea, is a distant second.
