NATO releases major report on effects of BPL
NATO (the North Atlantic Treaty Organization) has issued a report of the expected effects that widespread BPL application would have on the HF spectrum. Particular emphasis is placed on ambient noise in “quite rural” zones and the “Absolute Protection Requirement”. The calculations assume ubiquitous installation of BPL. The report concludes: a) High probability that BPL would cause increased noise levels at sensitive receiver sites given the projected market penetration; and b) The percentages are highly influenced by assumptions on transmitter EIRP, BPL market penetration, and duty cycle.” The entire report (9MB) can be downloaded at: http://ftp.rta.nato.int/public//PubFullText/RTO/TR/RTO-TR-IST-050/$$TR-IST-050-ALL.pdf [WIA]
