As a leader in the design, development, and deployment of cognitive radio technology, xG was asked to provide featured commentary for an article appearing this week in FierceBroadbandWireless titled "TV White Space Rules Open the Door for Even More Innovation."
The article details how white space spectrum is fast becoming a proving ground for what could be ground-breaking devices and services. Moreover, lessons learned from employing the technologies necessary to make white space commercially viable could also drive innovation over a host of other spectrum bands in time.
The article explains that, while the idea of using TV white space spectrum is novel enough, one of the keys for successful implementation is the use of enabling technologies like cognitive radios. These allow for "the opportunistic use of spectrum" either through a combination of a spectrum database to identify which channels are available at a given location, and/or employing spectrum sensing capabilities. Cognitive radio systems, as well as other technologies being developed by xG Technology like advanced interference mitigation and MIMO antenna technology, are key components required for the deployment of cost-effective, wide-area mobile broadband networks using white spaces.
A key differentiator is that, while the spectrum databases will let devices know which channels can be used, cognitive radio technologies can take that information, enhance it with their own spectrum sensing capabilities, and determine which channels they should use to maximize throughput and minimize self-interference.
xG's Vice President of Marketing, Rick Rotondo is quoted extensively in the article. Speaking about ways of utilizing spectrum more effectively, Rotondo said,
"You actually can utilize spectrum far better and increase your network capacity far more by using all that processing capacity in your cognitive radio to do interference mitigation. Enabling devices to identify interference and then null it out allows them to continue operating on a channel full of RF pollution. Such an approach provides a solution for the spectrum 'have-nots'–the guys who don't own a lot of spectrum."
