Qualcomm: we're flush with 4G patents
It looks like any hopes that the 4G intellectual property landscape would be a little less of a Qualcomm-controlled minefield are fading fast. Thanks in part to recent acquisitions, a senior vice president pointed out in a recent interview with IDG that the company now owns over 1,000 patents pertaining to OFDM, OFDMA, and MIMO -- technologies which'll prove crucial to 4G data, regardless of the standard(s) that ultimately win out. In other words, whether the networks of tomorrow are banging LTE, UMB, or some flavor of WiMax, Qualcomm's confident that it's in a position to cash in, just as it's doing now. Sorry, Nokia.[Via mocoNews]
Adaptix new SX-300 and SX-500 Mobile WiMax base stations
They may be jumping the gun, oh, just a little, but Adaptix is launching two new Mobile WiMax base stations, the SX-500 and SX-300, intended for mobile and vehicular uses, respectively. But doing IEEE 802.16e-2005 compliant OFDMA WiMax isn't just all this thing does; these devices will be imminently updatable and upgradeable as they're equipped with software defined radios. For example, already plans are in place to shoehorn in MIMO capabilities and 802.22 Wireless Regional Area data networks over TV bands into these units; in theory they could even be hacked to be WiFi APs or WiMax Bluetooth DUN modems -- but we'll not get ahead of ourselves here. No, as always we'll patiently wait for Adaptix get these in the hands of the users before we start letting our imaginations run away with us in wireless flights of fancy.
