morcheeba's Journal: Satellite radio wants 802.11b/Bluetooth emissions restricts

Commsdesign is reporting that Sirius Satellite Radio is petitioning the FCC for stricter emission requirements, which could cause serious problems with license-exempt services in the 2.45GHz band such as 802.11b and Bluetooth. Even though Sirius knew what the acceptable levels of pollution were in its band (2.320-2.345 GHz), they now want these lowered. Motorola's response indicates that vehicle ignition systems may be the biggest contributor of noise. Intersil (a maker of 802.11b chipsets) had an even more scathing response, blasting Sirius for a poor design (link margin only 6.7dB) and even claims that the new restrictions would be below the thermal noise floor.
