Can you tell us how this network is structured? How many Tropos units per backhaul radio are used? What platform is used for backhaul? Is it 5, 2.4 or 900 for backhaul? How is the performance of this network? Anything else you can share is appreciated.

    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

    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
    <http://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.
