A Wireless ISP Primer

           Tranzeo Wireless
 BC3/FNTC Regional Workshop
Who is Tranzeo?
• Tranzeo Wireless Technologies Inc.
  (TSX:TZT) has emerged as an industry
  leader in designing, manufacturing and
  distributing high-speed wireless
  broadband communication systems
  globally.
Tranzeo’s Competitive Advantage
• Ease of doing business with us
• Quality & Reliability of our products
• Our very qualified Tech Support Group
• Sales Support – help design the most
  efficient & cost effective solutions
• Cost effective solutions/low risk solutions
Key Wireless Elements
• Proper preparation through site surveys,
  marketing and business plan
• The right equipment chosen for your
  unique location
• Great support staff to service all your
  wireless needs
• Professional Installers
• A strong working relationship between
  client and vendor
There is no WISP in a box
• Every location has unique needs
• There is no “Swiss Army Knife” of radios
• A good vendor will help you plan out the
  system based on your plans and your
  locations
Bandwidth Feed
• Make sure your feed meets your needs for
  the short term, and can be scaled up for a
  reasonable cost in the future
• The supplier of your bandwidth holds your
  business in their hands, choose wisely
Bandwidth Control
• Wireless requires bandwidth control
• Bandwidth should be controlled on two
  levels, intranet and internet
• Kazaa, games, virus of the hour, are not
  the only issue.
• Speeding up some classes of service at
  the expense of others makes for happier
  customers, i.e. high speed for Mail,VoiP,
  Video; low speed for Kazaa
User Control
• Get paid for your bandwidth
• WEP - Wired Equivalent Privacy
• MAC AUTHENTICATION
• WPA -     Wi-Fi Protected Access

• Radius Server -        provides remote
  user authentication

• PPPOE - Pt.toPt. Protocol
  over Ethernet

• QOS -     Quality of Service
Site Survey
• Not a option in more crowded environments
• Calculations must be tested in the real world
• Put it up and see what happens is a recipe for
  disaster
Site Survey
• A site survey will:
  – Suggest the quantity and position of access
    points
  – What antenna type to use
  – What channels are available and work best
Access Point Location Selection
• Generally, cost determines the location,
  not RF, in the real world
• Where can you get tower space?
• Where can you get bandwidth?
• How much is it going to cost?
802.11b
• (DSSS) Direct Sequence Spread
  Spectrum
• Cost effective solution for Point to
  Multipoint
• Uses 2.4 GHz bandwidth.
• Bandwidth is becoming crowded in many
  areas
802.11a
• OFDM (Orthogonal Frequency Division Multiplexing)
• Cost effective solution for Point to Point
  feeds- up to 40 miles plus.
• Point to Multi-Point solutions for high
  throughput requirements
• Low cost client units now available
• Uses 5.2 to 5.8 GHz
Channels – 2.4GHz
• 802.11b operates in an unlicensed area of
  the 2.4GHz ISM (Industry, Scientific Medical)
  frequency band.
• Each channel is 22MHz wide
• To minimize interference each radio needs
  to be spaced 25MHz apart
Channels – 2.4GHz
• Since the spectrum is only 80 MHz wide,
  that means that in any area, you can have
  at most three non-interfering access
  points.
• Studies have shown that a 20 MHz spread
  has minimal effect
802.11a – 5.8 GHz
• 5 non-overlapping channels in upper band
• 4 non-overlapping channels in middle
  band
• Lower band is illegal in North America
• Channels are 20 MHz apart
Line of sight is more than being
     able to see the tower
Fresnel Zones

• The Fresnel zone is a elliptical area which
  can not contain obstacles
Polarization
• Horizontal vs. Vertical
• Horizontal Benefits
  – +20 db from most sources of ISM (Industry,
    Scientific and Medical Band) noise

  – Better multipath results
• Vertical Benefits
  – Less Expensive
  – In the past it was easier to find Vertical
    Equipment
Weather
– As a general rule, wireless frequencies are
 not impacted by rains, snow, or thick fog
– At 2.4 GHz, attenuation is 0.01 dB/Km for
 150mm/hr of rain
Signal Propagation/Free Space
              Loss
• Radio Waves lose power over distance,
  according to a fixed formula, called the
  Free Space loss. The greater the
  distance, the more will be lost.
TX Power
• TX power is the amount of power a radio
  transmits. Generally, the longer the
  distance you want to go, the more power
  you need.
• Power is not the most important element
  of a link, receive is!
RX Power
• Rx Power is the lowest level at which a Radio
  can detect signal from noise.
• The Lower the level, the better the radio.

• As opposed to:
  RX Sensitivity – which is a measurement of the
  weakest signal a receiver can receive and still
  correctly translate it into data (-75dB is better
  than -90dB in actual performance)
EIRP (Effective Isotropic Radiated Power)
• A measurement of the total output of the
  system, including the antenna
• Legal limits exist on the amount of power
  you can emit.
DB vs DBi vs DBm
• A dB is unit of measure that allows for
  easy calculations. Every 3 db increase
  means a doubling of power. 20 db = 100
  mW, 23 db = 200 mW
• A d(Bm is means a db at a certain level of
  resistance. In RF, its 50 ohms. Therefore,
  0 dbm = 1 mW at 50 ohms
• A DBi is a measurement of how much an
  antenna focuses a signal (gain).
Radios
• Integrated Panel - combining both a radio and
  an antenna - some have fixed dBm output and
  the are some with controllable high gain output –
  can be used for outside or inside environments
• N-Connector Panel – radio only with an N-
  Connector – LMR cable is used to connect the
  unit to a separate antenna
• Indoor radios – radio with connector to allow a
  separate antenna to be connector inside or
  outside
Antenna Types
•   Omni
•   Directional (Parabolic Grids & Dishes)
•   Sectorized Panel
•   Panel
Omni
• Put out a flat, circular pattern
• Best used where AP and clients
  are at the same heights
• Patterns change as power changes
• Generally have vertical polarity
Sector
• Highly Directional
• Cover a wide range both
  horizontally and vertically
• Common degrees of beamwidth are 60, 90
  & 120
• Allow for use of a greater
  number of channels and
  higher radio densities
Parabolic Grids
•   Highly focused beamwidth
•   Excellent for dealing with trees
•   Low cost
•   Highly recommended for
    backhaul use
Interference Countermeasures
1. Try to keep links short, as Fresnel
  increases over distance
2. Avoid the noise by using tight Beam
  Antennas
3. Use a different Frequency or polarization
4. Try a different Antenna
5. Move the Antenna to a different location
Customer Premise Equipment
• Key to your success
• Proper device selection means no “truck
  rolls” (on site service)
• Improper solutions cost you customers
  and waste your time
Why not use a cheap SOHO device
• SOHO (small office, home office) devices are made
  to go hundreds of yards, proper CPE
  equipment is designed to go miles
• Generally vertically polarized
• Not FCC certified if modified.
• Warranty usually voided if modified
• Not tested for outdoor use
• Often use Omni or vertical Antennas
Power Over Ethernet
• Makes installation simpler and cheaper
• No cable loss
• Must follow manufacturer instructions
Cost of Equipment
• Lowest cost is not always the best for
  bottom line
• Neither is high cost a guarantee of
  success
• Tranzeo Solutions
  start at as low
  as $157 CDN
Support Costs
• Like any ISP operation, there will be
  support costs.
• If the head end is set
  up right, and the installer
  follows the basic rules,
  the install should work
  without an issue
Other items
• Plan for a 1% equipment fallout rate per
  year.
• Weather should not increase support calls,
  unless it is freezing rain
Optimizing ROI
• Standardize on two or three models.
• Use gear that can be repurposed.
• (Our products are backward compatible)
• Avoid proprietary standards if possible
• Plan to recover CPE costs as soon as
  possible
• Investigate leasing the equipment
What should a vendor Provide
• Support
  – How long is the support period? Ours is life of
    product.
  – How can I get in contact with support – toll
    free line
• Warranty
  – 1 Year from purchase
Vendors

•   Are they familiar with operating a WISP?
•   Tranzeo is – Whistler, Port Coquitlam
•   Do they offer training?
•   Are they FCC certified/certifiable?
•   What do other ISP’s think of them
•   Do they upgrade their technology in new
    units or firmware (internal software)
