After all the standardization around MCoA/IFOM, building all the
hype/coolness around driving one flow on path and another the other path,
its sad to note that we simply don't have the devices/or the battery
technology that can keep multiple radios up at the same time for a
reasonable length of time (except few exceptions). Most devices/operator
configuration still try to keep only one radio active at a time, so they can
claim better battery serving time. So, we are not there yet, but from what I
believe with LTE radios, the power requirement is only going up. Hopefully,
there will be a major breakthrough in the battery technology that will allow
all the radios to be up for a day with a recharge ...
