BPL comes into your house at the power company service box. Even if you don
not connect to it. FACT: The Cedar Rapids deployment has a WLAN link from the pole. The wires carry the 2-80 MHz. How does that go from 2-80 MHz --into-- the house? Umm..."rf propagation"?? I thought you designed antennas...you don't know THIS? It creates S9++ signals from 2 to 80 MHz. FACT: Sure, if you drive your 1972 Nova with 'HAM ON BOARD' sticker (for example) under the power line, this is a consistently true statement. Otherwise, there are some, few, circumstances in which an unacceptabel (pun and sic intended) level of 'hash' Hmmm...ok, this is for "rural internet access." "Looking out the window, what do I see? A POWER POLE!!" Oh, 50ft away or so from the house. Hmmm...BPL at 50ft....??!!?? (Oh, and the car is a T5 Volvo...5 spd manual, of course...no stickers...just speed & style) Based on assumption, the number of hams affected nation wide is in the hundreds. Of thousands? Last time I checked, most houses had powerlines SOMEWHERE in the general vicinity. FACT: Sure, if very nearby and unfiltered, this could be a problem. However, the FCC rules require filtering for RFI mitigation in such circumstances. See above. Ever tried to get the bloody power companies to fix an arcing insulator?? FACT: A vocal minority of hams want to 'kill BPL'. As opposed to working with the power companies to fix the problem. Hmm...Germany and Japan are a "vocal minority?" Both tried it, and discarded it due to interference. THAT "fixed it," but good. WLAN (mebbe 5.6 ghz or so? W/a cable feed?) is a good idea, tho. PLC is not. Duke Power (Duke Energy) is working on some trials.....I unwittingly drove thru one neighborhood w/PLC and later realized that I had done so....interference ranges from S5 to S9+ on my mobile. The houses are not much farther away from the PL than my mobile. Empirical data says that interference would be present there, also. I had shut off the mobile as I wished to save my ears. Thought something had started arcing nearby. Heh...and just wait 'til the sunspot cycle starts back upwards.... A |
