Strategic EHF Comms Wideband SHF Protected Comms Wideband L, C, Ku, Ka- band Comms

AEHF WGS Commercial

  • Mix of packet and circuit switched

capacity

  • Adaptive links for channel

conditions – built-in protection

  • High bandwidth trunks/circuits
  • Support for small user terminals
  • Integrated EHF, SHF, Ka band

services

Circa 2000 Circa 2005 Circa 2015

  • Circuit switched
  • Unconnected, separate services
  • Limited support for small terminals
  • Low protected capacity
  • Internet-like transport with

interconnectivity and cross-banding

  • Support for small, mobile terminals
  • High protected capacity

  • AFRL leads the way in space technology

– New affordable means for reusable access – Smaller, cheaper, more capable payloads

  • Partnership counts!

– Collaboration with NASA is strong and growing

  • Need attention to assure tomorrow's talent pool
