In general, a location estimate may be derived based on measurements for satellites, base stations, pseudo satellites, and/or other transmitters and using one or a combination of positioning methods. Network(s) 120 may include a wireless network that supports radio communication for terminals ...
Apple on Friday enabled iBeacon location-aware transmitters at all of its U.S. retail stores, giving the company the ability to easily provide product information and allow shoppers to quickly check out via their iPhone. But initial tests byAppleInsidershow the use of iBeacons remains limited a...
The fakes have none of the RF suppression properties of the real thing. They will noise-up around plug-on transmitters and walkie-talkies. The output is about 3db lower than the genuine. (compensated for in the above sound file.) The painted lettering on the mic’s side is uneven and t...
Pioneering, early pinniped foraging studies used acoustic telemetry such as very high frequency (VHF) radio transmitters to describe at-sea movements [31,32] and formed the basis of our understanding of pinniped foraging. Feeding was inferred from breaks in the VHF signal from diving, assuming t...

Similarly, a study in the flightless Takahe (Porphyrio mantelli) found that daily energy expenditure increased 7.7% when using bird-mounted radio transmitters that weighed an average 1.8% of the birds' body mass though time budgets of the birds were not affected [27]. The authors suggested ...
