Some rules relaxed while measures added to prevent interference to wireless networks
Back in early 2013, the FCC took steps to help consumers deal with the dreaded cell phone phenomenon of dead spots by allowing the use of private signal boosters. (Readers should recall that boosters receive and re-transmit cell phone signals to improve coverage in their immediate vicinity.) And now, underscoring its interest in encouraging such devices, the Commission has tweaked its rules. But be forewarned, the tweaks are highly technical and unless you’re deeply involved in the manufacturing side of the booster universe, you shouldn’t expect to notice any dramatic changes.
To recap, there are two classes of approved boosters, Consumer and Industrial. Consumer boosters, in turn, come in two flavors, Wideband Consumer Boosters (designed to boost signals of more than one cell provider) and Provider-Specific Consumer Signal Boosters (designed to boost the signals of just a single cell provider). All Consumer Boosters are subject to “Network Protection Standards” (NPS), although those standards differ somewhat between the two different types of Consumer Boosters.
Among the NPS imposed on manufacturers of Wideband Consumer Boosters was a testing requirement – involving downlink noise limits, if you really must know – which proved problematic for manufacturers. (As it turned out, neither the FCC’s Office of Engineering and Technology nor most Telecommunications Certifying Bodies had the filtering equipment necessary to measure the downlink noise as required, which obviously complicated the testing process.)
So several manufacturers, noting that the downward noise testing element was not included in the NPS as a means of protecting against interference, suggested that it could be tossed. They also suggested that bidirectional capability, which was what the downward noise limit test was designed to help achieve and confirm, could be addressed in other ways (for example, by adding downlink gain limits to the Transmit Power Off Mode requirement – we warned you that the tweaks are highly technical, didn’t we?).Continue Reading...
