FCC and Part 15 Regulat ions
Frequency usage governed by FCC – Part 15 regulations for unlicensed usage Part 15 covers an assortment of electronic equipment that generates RF energy whether it ’ s intentional , unintentional or incidental
– Definitions Interference Harmful interference Spurious Emissions Intentional Radiator Unintentional radiator Incidental Radiator Digital Device Class B digital device Copyright 2009 WISP--Router, Inc.

Par t 15 Myt hs
Signal levels are very small not likely to cause harmful interf erence erence – Allowed levels to protect on neighbor’ s television from another neighbors video game as an example – Not enough always to protect sensitive reception equipment
“Type Accepted”
– Requirement Part-15 devices, transmitter and digital device are type type accepted has been written out of the rules
Verification
– Manufacturer self approved process (computer parts not connecte d to phoneline or contain intentional radiators such as Single Board Computers)
Harmful Interference – Rules require that manufactures test products to ensure that th ey do not exceed the absolute maximum limits and that products can not ope rate in such a way that they do NOT cause harmful interference. – Operators are responsible for correcting the interference or to stop using devices if harmful interference occurse

Type of Devices
High Power Intentional Radiators – Specifically authorized intentional emitters – Allowed – Allowed radio power as much as 1 Watt – Specific radio frequencies only – Device Certification Required – Examples: WiFi equipment Garage door openers Cordless phones Baby Monitors
Low Power Intentional Radiators – Allows – Allows usage on nearly any frequency – Very – Very limited to specific field strengths depending on frequency – Device Certification Required – Examples:
FM transmitters (MP3 docks for car stereos as example)
Unintentional Radiators – Radiated emission limits above 30MHz – Conducted emission limits below 30MHz – Most common are computers and similar digital devices
Incidental Radiators – PartPart-15 requires that they use good engineering and they not cause ha rmful interference to radio service – Include devices like motors and power lines Copyright 2009 WISPWISP-Router, Inc.
Unlicensed Fr equencies (700MHz) 900MHz 2.4GHz 5.15-5.25GHz (indoor use only) 5.25-5.35GHz (low power outdoor) 5.8GHz (high power outdoor) 24GHz 60GHz
