Unlimited wireless services from a single antenna? Maybe
Quite possibly, but right now 4 is considered a breakthrough if it works. Even if the transmission is digital, radio waves themselves are by nature analog, and conventional wisdom states that efficient antennas are dimensionally tuned to the wavelength of the signal. Enable a bunch of wavelengths in a single device and you consume a bunch of space with antennas, until now.
At the heart of all wireless communications lies an antenna, or in the case of today’s mobile phones and laptops that need to receive Bluetooth, Wi-Fi, EVDO, WiMax or DVB-H, sometimes two or three. Packing each of these antennas into a small form factor is expensive and can cause interference problems, so when I saw that SkyCross, an antenna company in Viera, Fla., had managed to receive several signals on one antenna, I thought that was pretty sweet.

Combining the new wave of software defined receivers and transmitters with a single efficient multi band antenna will drive unlimited innovation in the wireless space. We live in exciting times indeed!

What’s really slick, with software defined radio, should a new std come for cellphones, say LTE2. A flashable memory could permit the end user to download the new code and have a ‘new’ old cell and not be out of pocket an handset changeout. Sweet.
Intel rolls out multiband wireless on a single chip | @ 3:39 pm
[…] February 5, 2008Intel rolls out multiband wireless on a single chip Very large scale integration is coming to wireless devices. Recently, we reported that small, efficient multiband antennas are on the way. On the heels of that news, intel has release an single ship transciver that handles Wimax and WiFi: What Intel says it has accomplished is the building of a die that supports WiMax and Wi-Fi a/g/n. In integrating a transceiver capable of handling multiple frequencies on a single chip, Intel has eliminated the use of a “front-end module,” technology that performs the same function today on a separate die, Hossein Alavi, director of communications circuits at Intel labs, told InformationWeek. Eliminating the separate module would ultimately enable the building of a smaller processor with lower power consumption, two important attributes for portable Internet devices. […]
SDR Anyone? | @ 9:53 am
[…] February 7, 2008SDR Anyone? Following on the Bosses post here, there is a very Geeky article in Linux Journal to get your hands dirty if you wish. Yes software defined radio on your kitchen table, from the guy who started the whole thing. Our setup consists of a conventional FM dipole antenna, a cable modem tuner module mounted on an evaluation board and a 20M sample/second PCI analog-to-digital converter (ADC) card. The antenna plugs in to the input of the tuner module. The tuner module IF output is connected with a piece of coaxial cable to the ADC input on the back of the computer. The tuner module eval board is connected to the PC’s parallel port so that we have a way of controlling the module. […]
