Won’t adaptive technology in BPL protect others from interference?
Adaptive technology was proposed by the FCC in the Notice of Proposed Rulemaking in 2003 as a way to mitigate interference. While sounding high tech, this technology is actually administrative functions that are present in most BPL equipment today. This includes: · Power control, dynamic or remote · Frequency notching · Harmful interference shut-down feature First off, these techniques do not provide any protection for mobile or portable stations. Dynamic power control is an obvious no-brainer and should be a requirement as this would keep power levels on the lines as low as possible. Frequency notching, while a possible solution for local interference complaints, doesn’t address long range interference that would be created by ionospheric propagation or the cumulative effect on the noise floor in the HF bands. The harmful interference shut-down feature is rather ambiguous in the NPRM, but it seems to be a manual remote control on/off switch.
