We contest the idea that copper wire is the answer to in-building high-speed communications and that ultra wideband has somehow shot itself in the foot. The current debate about ultra-wideband wireless standards is a normal part of the new technology introduction process, and simply demonstrates the high level of interest that this particular technology has.
It is clear that the consumer wants low cost, easy to use, seamless connectivity without wires. This is evidenced by the strong success of Bluetooth in providing connectivity between a wide range of devices. So, whilst we share some of Mr. Gomes's concern about the situation being "deadlocked for almost two years because of different technical approaches," we are convinced that ultra wideband will eventually be an even greater success. The benefits of a truly wireless, converged entertainment environment are overwhelming. Content can be delivered through any number of delivery channels, stored centrally, and then distributed in real-time to a listener or viewer in any room, to any type of fixed or hand-held device, or indeed to a user moving around the house. This is so compelling that disagreements about technical standards will be ironed out - either by the parties themselves or by the market insisting on products.
On the other hand, HomePlug is a derivative of a technology that has now existed for over 20 years. Some companies have commercialized low-bandwidth utility solutions (such as connection of doorbells) where the quality of signal is not a problem, but the high-bandwidth solutions, such as HomePlug, have yet to find real demand. There are a number of problems inherent in this technology, including major variations in electrical wiring topologies, interference from mains-powered equipment, and the fact that it inherently fails to serve portable appliances.
The debate raging at present around ultra wideband is a very natural one - revolving around how companies maximize their commercial position in this new application. This inevitably means fighting for their IP to be incorporated into any new standard. This process has worked for cellular standards, for wi-fi, and will work for ultra wideband. In our opinion the debate is a good thing, since without it there would be a real danger of the deepest pockets forcing a solution, which might not be the best result for the customer.
Many millions of dollars are going to be invested in ultra wideband over the next ten years - let's make sure they back the right technology.
