OK let’s review some Radio 101. Receivers use less electricity than Transmitters. (Please note Period at end of sentence, there will be a quiz on this.)
Wi-Fi is a Transmitter/Receiver, aka Transceiver. Wireless Telecom is a Transceiver. GPS is a Transceiver. 4G data (aka Wi-Max) is a transceiver (Lower case because really who has it?). Bluetooth is a Transceiver. 3G data is a Transceiver.
Quiz:
What will use more power:
A) Wireless Telecom with no other radios on unless needed?
B) Wireless Telecom w/ GPS, Wi-Fi (not connected and roaming needlessly) , BT (with no associated device nearby), 3G data, and 4G data (which is a ghost in most markets, is searching needlesly and does not exist in even major markets ubiquitously).
C) Wireless Telecom, GPS, BT (If you have a speaker phone or ear piece, if not consider it off) and WiFi off.
I apologize to the Mods in advance. It is not my intent to Hijack this thread from Appkiller to Radio 101. I just felt it was necessary to do some elementary education.
