I very much disagree:
Wireless has been moving towards multi-mode and multi-spectrum capabilities.
While WiFi has been limited in bands of spectrum and way the standard has
been devised and must be used (contention based rather than managed type
access networks), the major trend for wide area cellular and access networks
has been towards networks and devices that use multiple spectrums and
multiple modes of operation. WiFi devices do that only to a limited extent.
New multimode WiFi+cellular phones to a greater but still limited extent
because they switch modes of operation - phone service remains castrated.
If we wanted to think from the perspective of engineers we would likely
devise wireless based on what could be implemented now and within a
realistic time frame: we would think about developing products that take
advantage of various spectrum based on how the signals propagate not just on
one or two spectrum that are available or based on the limited focus of
earlier standards.
I would take 700 MHz and think that would be good for providing rural
access, suburban and urban VoIP, messaging and video broadcast/multicast
service. And a 'basic' level of urban environment broadband service as a
gap filler and backup for higher density of deployment, higher frequency
services where multiple spectrum reuse is advantageous. And I would combine
that with ability to operate in multiple other spectrums and standards
modes.
We already have an example of that, albeit in a prescribed 'walled garden'
service network: Qualcomm's MediaFlo combined with Verizon's 3.5G cellular
network: 700 MHz OFDM based system combined with 2.3 GHz mobile service.
The 700 MHz spectrum offers among the last available spectrum to provide
wide area rural service where number of connections can be expected to be
limited and very high penetration and low cost possible for digital
broadcast service IPTV, digital radio, messaging, localized adverting,
meter reading, traffic control, public safety/first responder services, and
many other services that can overlay more densely deployed, higher bandwidth
services.
Part of this picture is also 'graceful degradation' and redundancy of
fall-back connections: 700 MHz has the benefits of long range signal
propagation and penetration but that is a catch 22 in terms of bandwidth
density achieved through frequency reuse; network granularity, MIMO and beam
steering and use of smart distributed networking methods. But what users
most want, even more than bandwidth,is to easily get connected and stay
connected: most users will accept occasional lower bandwidth than being
dropped or not connecting altogether. So, if you can deliver a basic, or
'maintenance level' of bandwidth for generalized access (Internet) that can
be switched on seamlessly in shadow areas, inside buildings, or in rural
coverage areas, then that goes a long way to improving the user experience
at a relative low cost of spectrum acquisition and deployment cost.
Google recently submitted a statement to the FCC saying they would bid for
spectrum and make it commonly available if the FCC goes along with Chairman
Martin's open access proposal for the 700 MHz auction. They said they have
put up $4.6 billion which they estimate it will take to acquire spectrum to
provide national coverage. That seems like a lot but it is very cost
effective if used properly. And that is based strictly on what I know can
be done in the near term (next 3-6 years) .. technology is unlikely to stop
evolving anytime soon.
The major shift for wireless is in new business models:WiFi community access
'free' networks have an hidden cost of difficulty of getting and staying
connected, hassling with equipment, etc. We should rejoice each new sliver
of spectrum that becomes open access and advocate for more unlicensed
spectrum. Unfortunately, that battle was not effectively engaged for 700
MHz and the best hope for community wireless advocacy is for 20-30 MHz to
become open access. That will help make reasonable services available that
allow current and innovative new applications and content that can be used
on public access IP networks such as 2.4 and 3.6 GHz unlicensed.
