My imagination never seems to stray away from the idea that getting away from the telcos or getting our services from an entity other than the telcos is a productive, cost savings pursuit.
I still entertain the idea of a Wi-Max end to end network, but expect a combination Wi-Max/Wi-Fi network, preferably with typical phone providers completely out of the picture. If you will note, it usually gets quite expensive to get on an IP network, when you do so through the cellular guys. They give you a limited number of messages or a limited amount of data exchange and if you exceed that, charges can go up quite quickly. The typical fee you are charged isn't exactly all that impressive.
You are going to see the telcos using Wi-Max in the future. That's probably going to be a likely scenario, but don't expect them to offer the Wi-Max the way we should be receiving it. It should be CHEAP. They will need it to complete many of their networks, but don't expect them to pass on their savings. Again, I think you must get away from telcos for cost savings or cheaper offerings.
If you get under some of these new city wide Wi-Fi umbrellas, in some cases you're going to be able to get the Wi-Fi service FREE. Google has enabled one of those free Wi-Fi networks I'm dreaming of, with more to come. Their revenue model will be built on their advertising strength. They'll get dollars from you if they motivate or generate sales from you in their area of expertise, but you will not be paying for Wi-Fi directly. Quite interesting, don't you think? Some of the pay for Wi-Fi city wide systems, like the kind Earthlink has provided, seem to be offered at a very reasonable starting price.
So, you're only one real ingredient away from taking advantage of these wireless IP systems and Wi-Fi. You're about to get salvation from the phone companies and be able to make your calls for next to nothing, if you focus on Wi-Fi and then begin to look in the direction of Skype. Skype may not be the only option, but they are interesting to say the least and have inspired many business partners to use their service to make some independent and unique service offerings.
What keeps you connected now and provides an uninterrupted phone call, deals with multi-band, multi-mode chips in your phone and roaming agreements between phone companies.
Coverage developments which will make this dream a reality aren't fully inplemented just yet, but changes come quickly for Wi-Max and Wi-Fi. One possibility has developed that could represent a quantum leap towards full coverage. This one form of nationwide blanket coverage may be able to be employed more rapidly than any one might have imagined. You'll find information about that technology at the globetel link at the bottom of this article.
Here's my links to some articles that may better echo my ideas or express a similar idea with a bit more clarity. :-)
