Report on Recent FCC Ruling on Wide Band Frequency Hopping
Steve Shellhammer, Symbol Technologies

2. September 2000
Background
Over that last two years the FCC has been evaluating a modification to FCC Part 15 section 247 which regulates the operation of devices in the ISM Bands.
Rule change proposed by HomeRF
The proposal was to modify the rule to allow for wide band frequency hopping.
The IEEE has opposed the change due to the potential increased interference.

WBFH Ruling
Recently (August 22, 2000) amended Part 15 section 247 (See FCC ).
The purpose was to allow for high rate Frequency Hopping Spread Spectrum systems in the 2.4 GHz ISM Band.
Intended to give “parity” of data rates with DSSS systems (e.g. IEEE b)

Impact on TG2
Currently we are focusing our efforts the mutual impact of Bluetooth and IEEE
With this amended rule 10 Mbps HomeRF systems are now allowed.
This represents a new interference source in the marketplace.

Impact on TG2
Should we model the impact of the interference of HomeRF on Bluetooth?
When should we start?
