My article that appeared in EE Times this week prompted a response from a reader who asked me to look into another problem: The issue of which mode to select when both are available.
It is more complex than one might think at first. In today's environment the choice between 2G and 3G is based on the strongest signal and uses proprietary solutions.
WiMax/LTE negotiation is a different ballgame. If both signals are available it might be likely that different operators would be involved. In that event, a protocol based on a de-facto standards at the very least would be needed.
User cost, desired battery life, and maximum data rate might also be part of the negotiation.
Look for more on this topic later. Multimode may take a long time to happen but it is coming and it will have a big impact.
The article that started it all is available at Endgame: Will WiMax and LTE find happiness in multimode?
