You make the mistake of assuming that I am talking about an
unlicensed 3.65
product Charles. We would not likely build a UL version of all that.
I am in
complete agreement with you on 3.650 in terms of the end reality and
utility
of the band in a licensed versus unlicensed allocation. That is why I
support essentially splitting the band.

Hi Patrick,
But all the "fancy schmancy" technology you implement won't do @#$@
unless
3650 is licensed b/c interference from 20 other systems in the area
(including several from our GPS-synced FM-based FSK friends) eats you

A. More power Tom. B. Much more sophistication in the equipment yielding
much higher spectral efficiency and system gain.
Frequency plays a major role, but you need to understand that other
factors
are of almost similar levels of importance. For example, our 802.16e
version
of WiMAX uses SOFDMA with beam forming and 4th order diversity at the
base
station and MIMO with 6 antennae embedded in the self-install CPE
with a SIM
card. Couple that with higher power available in a licensed
allocation and
you get zero truck roll self-install CPE with no external antenna.

3.5Ghz does,
I find that hard to believe. 2.4Ghz couldn't do it, which is why we
rely on
900Mhz.
What makes 3.5Ghz appropriate for the task?
With 3650 from what I understood, is only supposed to be allowed for
PtP or mobile service only (not indoor) based on the high power
levels allowed.
Not sure whats at the other 3.5G ranges in US.

The benchmark is the ability to provide NLOS, portable or fixed
service to at least a 2 mile radius per cell, indoors.
5.8 doesnt really give true NLOS to that distance indoors
5.4 doesnt really give true NLOS to that distance indoors
4.9 doesnt really give true NLOS to that disance indoors
3.5Ghz does, to "portable" devices similar to the equipment used by
clearwire. Airspan for example claims their wimax solution works
indoors to about 3 miles out, which is pretty good IMHO.
When you can deliver a zero truck roll model with 90% or above
availablity, is when operators by the truckload will deploy
equipment. At that point, you will see deployments in the thousands,
like the ones in mexico of 750,000 homes serviced.

Frankly,
The FCC should really hurry up and finish the rules to allow the
industry
to
really take off. The common view with most manufacturers I have
found is
that until there is 3.5ghz or near spectrum available, there will
be small
and limited deployments of wisp size and not many large scale
deployments
outside of 2.5ghz or 700 mhz operators.

In the larger scale of things- when you compare this to a carrier
deployment which would deliver thousands of CPE's service, this
is a test. I know
of
one company that has recieved 28 STA's for 14 markets, for over 2000
CPE.

Jeffrey,
I have to question the "judgement ability" (or the lack of it)
of anyone who abuses the FCC rules to the extent of taking a
licensed "experimental" system and using it for a commercial,
revenue-generating
purpose. Someone who would do this is (IMHO):
1. Someone with no business sense
2. Someone with no appreciation of (or experience with) the
enforcement powers of the FCC
3. Someone who will likely turn out to be their own worst enemy
4. NOT someone who I could rely upon to provide me reliable,
long-term
WISP service.

It doesnt change the fact that many have launched "limited"
deployments as a "test" but still charged for the access
service, banking on the fact that the FCC has set the band
aside for unlicensed anyways, and that the chance of the FCC
cracking down on them is very low.
Im not saying this is right, but reality is such that they
will be evenutally amending the rules and the gear according
to my sources that is available today will be compliant. *shrug*

Band -
Clarifications
Recently, there have been some misleading advertisements
promising turn-key 3.65 GHz licensing services as a means of
avoiding interference in congested license-exempt ISM/UNII
bands. Although the FCC issued adopted rules
back
in March 2005 to open access to new spectrum for wireless
broadband
in
the
3.65 GHz band, a "minor" contention-based requirement has
delayed the
deployment of wireless broadband services in this band as
equipment
manufacturers currently work behind the scenes to iron out the
details.
As
things currently stand, deploying a 3.65 GHz system today falls
under
Subpart 5: Experimental Radio Service of the FCC Rules.
Infrastructure Investment & Experimentation under Part 5
needs to be done strictly from a "curiosity" perspective
rather than one of "commercial network expansion." Part 5
permits experimentation in scientific or technical operations
directly related to the use of radio waves. The rules provide
the opportunity to experiment with new techniques or new
services prior to submitting proposals to the FCC to change
its rules.
Some useful excerpts regarding Experimental Licensing
47CFR5.3: Scope of Service
Stations operating in the Experimental Radio Service will be
permitted to conduct the following type of operations:
(a) Experimentations in scientific or technical radio
research
(b) Experimentations under contractual agreement with the
United
States
Government, or for export purposes.
(c) Communications essential to a research project.
(d) Technical demonstrations of equipment or techniques.
(e) Field strength surveys by persons not eligible for
authorization
in
any other service.
(f) Demonstration of equipment to prospective purchasers by
persons
engaged in the business of selling radio equipment.
(g) Testing of equipment in connection with production or
regulatory
approval of such equipment.
(h) Development of radio technique, equipment or
engineering data
not
related to an existing or proposed service, including field
or factory testing or calibration of equipment.
(i) Development of radio technique, equipment,
operational data
or
engineering data related to an existing or proposed radio
service.
(j) Limited market studies.
(k) Types of experiments that are not specifically covered
under
paragraphs (a) through (j) of this section will be considered
upon demonstration of need
47CFR5.51: Eligibility of License
(a) Authorizations for stations in the Experimental Radio
Service
will
be
issued only to persons qualified to conduct experimentation
utilizing radio waves for scientific or technical operation
data directly related to a use of radio not provided by
existing rules; or for communications in connection
with research projects when existing communications
facilities are
inadequate.
47CFR5.63: Supplementary Statements
(a) Each applicant for an authorization in the
Experimental Radio
Service
must enclose with the application a narrative statement
describing in detail the program of research and
experimentation proposed, the specific objectives sought to
be accomplished; and how the program of experimentation
has a reasonable promise of contribution to the development,
extension,
or
expansion, or utilization of the radio art, or is along lines
not
already
investigated.
For further information regarding experimental licensing, the
FCC has a nice online FAQ that gives a step-by-step how-to on
experimental licensing: http://www.fcc.gov/oet/faqs/elbfaqs.html
