Technology Review – Skyterra Innovation 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 / Sky. Terra Next-Gen satellites will use massive antennas, higher power, and integrate with terrestrial network… …so devices can operate with small antennas at nearcellular power levels; enabling compact, consumer-attractive devices on the same platform March 30, 2009 C-20090330 -049 5
