My take – Part 2

• • It's frequently costly
  • You end up tied to a single vendor

• WIFI derived technology is “unreliable” due to:

• • Shared spectrum
  • Shared collision domain
  • Diversity of implementations

• But:

• • Fast and unreliable (within limits) frequently beats slow and reliable (consider Ethernet vs ATM Ethernet vs SDH etc)
  • It's cheap...
  • • The wisp business consumes the older generation technology (RF, chipsets, etc) as the consumer electronics industry moved forward which means we benefit from massive economies of scale without having to invest in them.
