One of the nagging problems of wireless convergence has apparently been at least partially solved.
As more and more technologies (cellular, Bluetooth, Wi-Fi, NFC, WiMAX etc) line up to gain a little bit of turf in a cell phone or other handheld wireless device, there has always been a question about how to deal with the number of antennas.
Some people call it "the porcupine problem."
NXP has launched a new producta highly parallel embedded vector processorthat reduces the number of antennas to three: one each for a high, middle, and low frequencies.
It seems unlikely that NXP will license the technology and it says its own products may be as much as two years off.
Still, the SDR folks (NXP calls it an SDR solution) should sit up and take notice. I was under the impression that the RF component was the toughest nut to crack. Maybe NXP had done it.
