I hope this works

12x times more battery life would be a big improvement for any 3g phone on the market. Especally with 4g right around the corner on Sprint's WiMax network. Cool

Why, does WiMax draw 12x the battery power that LTE does? Laughing

I think hes assuming that 4G technology will consum even more power than 3G. So, its good that this development is starting now so we wont have to mess with those issues when 4G becomes the standard.

Im just guessing though.

I would have to guess the same thing. However, the step from analog to digital reduced power consumption due to more efficient transfer of information.
It is obvious that 4G makes more efficient use of transfering information because of the speed involved. It is possible that the battery life in these devices will increase.

I would expect any 4G device to come beefed up in the battery department anyways counting on increased usage for internet. Just like when MP3 players started being put in phones. That might be where they were going with that also.
Just so there is more time to use a device before recharge, because people will undoubtedly use them more.

Who said anything about lte? Between WiMax and Lte no one knows how much battery life they will consume. hawkeye why would u bring up Lte without any facts other then to mislead people??? Eh?

Both LTE and WiMax are going to be consumption hogs. The Mbs demand on the DSP will be the factor for higher consumption. Since both LTE and WiMax will use OSFMD for downlink, they will be very much similar in consumption in that aspect. But LTE will use SC-FMDA on the uplink which will alow better power consumption as opposed to WiMax retaining OSFMD for uplink

LTE will actually be better in consumption over WiMax. But only marginal.

So any development of saving power is a plus for any of us and this student has stepped up an advancememt which will be welcomed.

I believe the article says it reduces the battery draw by 12x, referring to the amount of power the antenna draws. This will most likely not increase battery life 12-fold since the screen and other functionality will still draw quite a bit of power from the battery.

Think about it... When youre in a situation where you have low or no bars, your phone tends to search for service nonstop, resulting in a dead battery after usually about a half hour. So i think its safe to say that the antenna uses quite a bit more or the battery charge than the screen backlight or even the ringers.

that has to do with the antenna, but it is not the antenna itself. This is a programed function of the handset to enter a certain set of proceedures to communicate with the tower and try to resync the different channels that operate the data. The phone is not getting any information about what power level is needed to establish a connection, so the phone runs wide open trying to transmit to the best of its ability until it hears otherwise from the tower.
The antenna itself is not what uses up that much power, it is physically the uplink transmitter in the device.
