What is WiFiber?
Is Point-to-Point Wireless Microwave Radio Upper
millimeter wave transceivers and antennas as a
package High frequency (71-76, 81-86
GHz) Multi-gigabit-per-second transmission
(Voice, Video, Data) Fiber-equivalent Line of
sight Small footprint Tower, rooftop, window,
pole mountable Development trajectory up to

Range and Reliability

• No RF is impervious to weather our sweet
  spot is the last 1-2 miles
• We ONLY see torrential rain (3 inches per
  hour)
• The tradeoffs
• In dry air 10 mile range
• Over the course of a year
• Five 9s to a mile in 80 of the continental US
• Five 9s to 0.7 miles in the rest (FL-LA)
• Europe Longer ranges
• At Four 9s, distance doubles, and at Three
  9s, nearly double again useful in the 3rd world
• In a properly designed ring, the distance of
  each link can be doubled rotational diversity
• To repeat, we do NOT see dust, fog, snow, ice,
  scintillation, oxygen, molecule absorption, light
  rain, medium rain

GigaBeam WiFiber

• Form Factor
• Radio 1ft cubed
• Antenna 12 or 24
• Mount mono-pole, tower, window, or rooftop
• Pencil beam low spread, low dispersion
• Rated radio draw - 70 Watts (less than a light
  bulb)
• Measured draw 50-55 Watts
• Power output - 100mw (less than a cellular
  phone)
• SNMP Monitoring
• Installation 4 hours or less
• Alignment typically 30 minutes of the four
  hours
• Web based filing to get the spectrum license
  20 minutes

International

• Outside the US, fiber is less available and
• access costs are often double or more US costs
• CEPTEuropean wide bandplan granted
• UK, Ireland, Norway, Spain, others showing
  progress
• Circuits approved for installation in Australia,
  South Africa, Bahrain
• Growing interest in Japan, China, and Middle East
