Fiber


“All the cheap fiber has

already been laid.”

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 9’s to a mile in 80% of the continental US

• Five 9’s to 0.7 miles in the rest (FL-LA)

• Europe: Longer ranges

– At Four 9’s, distance doubles, and at Three 9’s, 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

FCC Licensing


• 13,000 MHz

– (71-76, 81-86, & 92-95GHz)

– 50+ times all cellular combined

– “Gobs of spectrum”

• Licensed pencil beams

• Nearly free to all comers

• Lightening fast approval process

International


Outside the US, fiber is less available and

access costs are often double or more US costs

• CEPT—European 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
