In technology, speed is almost universally the enemy of power, and that rule certainly holds true in the world of cellular data standards. You heard it from His Steveness himself -- one of the main reasons we don't have a 3G iPhone on store shelves is because he isn't happy with battery life on HSDPA chipsets yet (consumers' opinions be damned, apparently), and in general, runtimes on 3G handsets large and small flag their 2G cousins, sometimes by a significant margin. Happily, the wiz kids at NTT DoCoMo are on the case, crafting Super 3G / LTE chipsets on 65nm dies capable of burning through 200Mbps at "sufficiently low power consumption" for mobile use. There's still no word on when NTT DoCoMo (or anyone else, for that matter) will be launching a commercial network at LTE speeds, but the company's hailing this latest batch of chips as a "milestone" on that journey -- and let's be honest, odds are good that Japan's gonna be rocking this stuff years before the rest of us anyhow.

Hot on the heels of a snazzy new CMOS sensor and newfangled plastics, NEC's engineers are cranking out yet another innovation to make our next phone a lot more useful (for a whole lot longer). The M2 system LSI chip can purportedly "drastically cut the energy used by a cellular phone" by halving the energy needed by each element on the chip. Notably, the firm has suggested that a cellphone battery currently lasting seven hours would be able to maintain that life even if "twice the power is required for high-speed telecommunications." A host of sophisticated technologies and software regulations are behind all the energy conserving magic, but the news you care about is that NEC plans to start shipping samples of the ¥5,000 ($41) device in the very near future, and it should hit a variety of 3G handsets by the year's end.

We've got phones so tiny we can barely dial our intended contacts, Bluetooth headsets that allow calls to be placed by just lifting a hand, and now Sanyo Semiconductor is giving the couch dweller in us all another glimpse of jubilation with its latest chip. Although typical BT earpieces combine a speaker and microphone for an all-in-one conversation solution, even the tiniest of units aren't exactly discrete, and if your surroundings happen to drown out your voice, your only solution is to escape the racket or yell louder. Sanyo is hoping to ease the frustrations of current handsfree applications by creating an LSI chip that can be worn in one's ear and yet still transmit outgoing audio. The device operates by picking up the faint diaphragm movements that occur whenever you utter even a whisper, and magnifies the vibrations into spoken words that your recipient can comprehend. While the eardrum emits voice signals "at a strength of about one-30th that of the voice itself," the circuity can reportedly transform comments made under your breath into phrases heard loud and clear. The company isn't handing out release details nor giving any indications on how much these will cost, but it looks like we'll all be one step closer to double-agent status should these ever hit store shelves.
