can anyone ediucate me on if/why 4g power consumption is symetrical for transmit and receive?
Its something that been niggle me for a while now. I have started to listen to internet radio in the car using 3, getting more than adequate, nearly dropout free service on my commute through rural low population parts of the South East.
Now, on a radio set, receiving uses little power as there's no need to transmit at the same time.
With internet radio and IP traffic, you always need to have a 2 way link going of course. Hence the high power consumption when listening to streams...
BUT the vast majority of traffic is incoming, not outgoing, packets. Was not 3g designed to be cleverly asymmetric, and only use power in proportion to packets being sent? OK perhaps not.
But 4g surely HAS been designed this way in the light of experience, and the tremendous advantage that low power consumption can have?
