Hi Tom,

The WHOLE PURPOSE of a WiFi Mesh Network Strategy is to AVOID THE COST OF
THE CPE & TRUCK ROLL

Now -- whether this theory works in practice is a whole nother issue

-Charles

P.S. FWIW - personally, I find the the concept (from an ROI perspective) of
a service provider WiFi mesh to be a bit far-fetched, but then again, 10
years ago, I told the founder of half.com that you was bonkers, and proceded
to get into the wireless biz =/

The primary difference being that in the Canopy Fixed Wireless you are 
including end user CPE. The largest cost to detur take rate when WISPS make 
subs pay for it.

Its likely that one can assume that many of the subscribers will need to 
install outdoor equipment (adding $100-$300 BUCKS), to reliably connect to 
the mesh.  So you could easilly add $1.5 million to the mesh cost for CPE, 
or remove $1.5million from the Fix Wireless plan if you were going to 
compare apples to apples.

What Mesh still has on its side is mobility.  The question is what value 
should a WISP put on that. Mobility can be easilly be the reason to justify 
why a muni should support a oublic interest project. (cable and DSL go to 
the home but NOT mobile for teh community to share.).  Mobilty also allow 
Muni type applications, such as to support travelling users (commerce), or 
Mobile government work force.  Mesh also gives Muni bargining power in the 
deployment, as it uses an asset of value that the governement has to trade 
and offer (easements, light poles, and power from them).

In a Fixed Wireless deployment it could easilly be argued that teh 
givernemnt has little assets of value to the provider. Its usually the 
independant property owners tht have the preferred assets for signal 
distribution.  For example, in my county, I am allowed free access to city 
infrastructure as a requirement that allowed tower building restrictions to 
be passed years ago. But yet I chose to pay for broadcast sites, because teh

Governement do not own the best sites that are advantageous to me.

Part of my point is that its not jsut the radios costs that are relevant.

I'm starting to think that the Tropos, use all verticle, use only one 
channel all across the network, design may not be to bad an ideas after all.
If it solves the challenge to get mobility well, and does not work well for 
subs inside their homes, it still allows lots of spectrum for the high 
quality Fixed Wireless providers.

Part of the arguement is that its possible that MESH may be the only way to 
get mobilty well. And maybe the answer is to deliver it with the least 
impact on everyone else.

Of course Alvarion mobile products have shown otherwise for vehichle mobile 
solutions.

So what would happen if more Fixed Wireless manufacturers made Mobile CPEs? 
Would it get rid of some of teh need of mesh? Sure mesh gives person/laptop 
mobility, but will any one really use it?  There is a good arguement that if

usage of hotspots is low in public areas (parks, cafes, etc) it would be 
even lower on the streets and such.  There is still very little evidence 
that communities will get the MESH signal insidet heir home reliably without

external CPE equipment.

>a whole 49 square feet, eh ?  Real hard.  :)

Some interesting thoughts for Friday

I forget the exact numbers, but Tropos recommends something like 20 APs /
square mile to get 95% coverage at b/g rates

49 square miles = 49*20 ~ 960 Aps

Part# MTR-52103000-500AA is a 500 pack of HotZone Aps on their price sheet
that goes for about $1.5 million list So that's $3 million in Aps -- for
simplicity -- lets assume that mounting hardware, power taps, etc is equal
to the equivalent in discount Then we need to add in the additional
infrastructure, like backhaul SMs, Routers, Servers, etc and the services
required to install / implement the system...

Experience from a similar type deployment (~40 square miles) pegs the entire
project at about $5 million for E,F&I

Market Data:

Census information puts Anaheim w/ a population of 328k people (97k
households)
Median income for a household is $47k
According to the March 2006 PEW Internet report -- in 2006, 46% of the
population that makes between $30-75k / year have broadband at home So the
total addressable broadband market in Anaheim is 46k subscribers of which
99% today are probably using some sort of landline cable / dsl broadband
solution that is bundled together w/ their TV/phone service

With a 10% penetration rate (that's ~5k subscribers) -- total revenue comes
out to about $110k / month

Assuming ZERO marketing, provisioning, customer service, bandwidth, support,
repair costs -- the breakeven point for this system is 5 years (ouch)

Lets look at fixed wireless

49 square miles is basically equivalent to a 4 mile ring around a tower
Remember

Area = (Pie)(R)^2
A = 3.14*4^2

A Canopy SM (averaged b/n 900 & 5 Ghz) costs about $300 complete (w/
antenna, mounting hardware, power supply, etc) A Canopy AP costs about $2k
complete (dividing up GPS sync, etc)

5k Canopy SMs would cost me about $1.5 million
The associated install costs (@ $50 / install) costs about $250k At 50 SMs /
AP -- the AP costs runs around $250k Infrastructure / Hardware / Switches /
Site Ac / Engineering / etc would cost about $100k (remember -- this is only
a 4 mile radius =)

Interesting Thoughts:

Moto-Mesh System Cost to service 5k customers within 49 square miles: $5
million Canopy Fixed Wireless System Cost to service 5k customers within 49
square
miles: $2.5 million

Hrm...

EarthLink Unwires Anaheim, Announces Wholesale Program By Tara Seals Posted
on: 06/29/2006

EarthLink Inc. launched a municipal Wi-Fi broadband network in Anaheim,
Calif., and announced a wholesale Wi-Fi access strategy on Thursday.

EarthLink has won bids in several cities to provide citywide wireless
Internet access, including Philadelphia and San Francisco, but Anaheim is
its first commercial launch. It's also the first piece of a strategy to
create a nationwide footprint of municipal Wi-Fi networks by tying together
all EarthLink municipal markets under one service.

Hand in hand with creating the footprint will be an open-access wholesale
program. The ISP already has two national wholesale partners, announced
today: PeoplePC Inc., EarthLink's wholly owned subsidiary, and DIRECTV. It
also plans to partner with local ISPs that want to provide Wi-Fi service in
their respective markets.

The portable, wireless service will provide high-speed Internet access for
residents, businesses, visitors and municipal employees. Anaheim's
49-square-foot buildout is expected to be completed by the fourth quarter.
Curt Pringle, the mayor of the city, officially unwired the city at a
wire-cutting ceremony this morning.

"The days when Anaheim residents, workers and visitors are tied to a desk to
access an affordable broadband network are coming to an end," said Garry
Betty, president and CEO of EarthLink. "The launch of this network enables
people to make a choice about how, and from where, they want to access the
Internet securely."

For $21.95 a month, Anaheim subscribers receive eight mailboxes and
protection tools such as a spam blocker and security, and will be able to
access the Internet from across the municipality, whether sitting in a park,
at a café or elsewhere. Customers also can purchase a Wi-Fi modem for
at-home use. In addition, EarthLink has reached a nonbinding agreement with
AOL LLC and is discussing ways to offer its AOL.com content and Web assets
on the municipal footprint.

The network also will serve city departments and businesses; EarthLink's
wireless network offers speeds comparable to existing T1 solutions, the
company says.

For occasional-use customers, EarthLink offers rates ranging from $3.95 for
a one-hour pass to $15.95 for a three-day pass. Occasional-use customers
will connect and access account information from the EarthLink portal page.

Consumers can visit www.EarthLink.net/wifi and provide their phone numbers
and addresses to see if the network has been built out in their area. If
unavailable, they will be added to a waiting list and will be notified when
the service is available.

As for infrastructure, EarthLink has deployed Tropos Networks' MetroMesh
Wi-Fi routers on light poles throughout the city to form a wireless mesh
that is operated and optimized using Tropos Control and Tropos Insight, a
suite of end-to-end configuration, monitoring and maintenance tools.
EarthLink also uses Motorola's MOTOwi4 portfolio of products, including the
Canopy high-speed backhaul and Wi-Fi mesh network equipment.
