The terminology can be confusing, but let's take a closer look.
There are terms specific to the network range or utility like:
None of those terms specify what technology is used in that range.
PANs can be IR or Bluetooth or even Wi-Fi
WLANs can be Wi-Fi or microwave
WANs can be CDMA, GSM, or Wi-Fi
Are you equating peering with the software controlled mesh of Tropos
or does this mean something else to you? While there are mesh networks for
consumer use like http://www.locustworld.com . This is a completely
business model than those of Vivato, Cometa Networks or Tropos.
As for the importance of the type of connectivity I think that's truly an
application. If I'm a traveling consultant my solution would look vastly
than the PDA solution for a dock worker of a trucking company. There would
also be different requirements for the PDAs carried by a Federal Express
As for Wi-Fi being there, first. Um, well what about CDPD? Why wasn't it
a success? The wireless operators were certainly around before Wi-Fi
products hit the market. This is an important indicator. End users found
Wi-Fi could be used to solve their problems. Wi-Fi has also been a better
choice for extended corporate LANs and allowing more mobility within the
enterprise's geography. Now, that some innovators are making this same
technology available at greater distances, it will continue to be attractive
for the same reasons, at least for data communications.
