Technology Review – Skyterra Innovation

SkyTerra Next-Gen satellites will use massive antennas, higher power, and integrate with terrestrial network…

…so devices can operate with small antennas at near-cellular power levels; enabling compact, consumer-attractive devices on the same platform

Current satellites are small, low-power, and do not integrate well with terrestrial networks…

…so devices require bulky antennas and amplifiers; they cannot replace or compete with regular cell-phones

3GPP2 L-Band Channelization Plan for ATC

► Skyterra intends to deploy an HRPD/eHRPD terrestrial network using ATC L-Band spectrum (i.e. 34 MHz)

► Skyterra incorporates a 50 kHz raster (i.e. channel center frequency separation):

• The channelization plan requires two 0.625 MHz guard-bands (at either ends of the uplink and downlink spectrum) resulting in 657 usable channels.

• The starting and ending frequencies for the Access Terminal and the Access Network will be outlined in a 3GPP2 work-item requesting ATC L-Band be added to the C.S0057-D 3GPP2 Band Class specification.

Wireless Evolution

Along with the industry, SkyTerra will compete in the next explosive growth phase of cellular…

► Mobile Data Growth• More availability of mobile content coupled with devices better

designed to drive greater Internet and data access• Future networks will be “Fat Pipes” built on all-IP 4G standards

► Smarter Phones• Along with software driving device value, key differentiators in the

device and network will drive adoption, stickiness and ARPU growth

SkyTerra’s Next Gen network will enable broadband, mobile communications on mass market wireless devices with the critical differentiator afforded by a powerful satellite system
