If you look back to the research report you'll find a few problems with wi-fi that Telkonet can solve.
A big issue with wireless technology is security, especially within the hotel industry where business men and women use the internet the most. These people have to be very careful about leaking company information. Within the wireless sector, it is easy for a hacker to find out what you are looking at and/or researching and with telkonet's technology this isn't a problem. Furthermore, many users at hotels have complained about abruptly losing the signal, which can obviously be desruptive and annoying. With telkonets system, you will never lose the signal - telkonet's service is similar to wireless in its portability, but will not lose the signal and possesses top knotch security.
Perhaps in the future wireless will become better than it is currently, however I can't see how they could secure their lines with a wireless signal. Either way, it will take a long time for things to change. For example, in the cable tv industry there already exists HD and satellite type services but the existing companies are still using CAT5 wires. WHY? Because they have invested hundreds of millions of dollars for their services and are going to make them last for as long as possible, as long as they can hold off and switch to something new and better.
Telkonet on the other hand is something new and better, but utilizes the existing wires that are already available to the consumer through their existing cable and telephone wires that go to the building or development. Therefore, EVERYONE that would consider wi-fi now has the opportunity to consider the same type of system without the problems - for less money and less time for installation - everyone wins in the end. Hope this helps.
