More on Packets
  • A packet can contain any kind of information
  • Web text (about 1/3 page per packet)
  • Music (about 1/10th of a second)
  • Low-definition Video (1/5th of a second)
  • HD Video (1/200th of a second)
  • Digital photos (1/2000th of a high-resolution
    photo)
  • Phone (about 1/5th of a second fits in a big
    packet, but usually phone uses small packets with
    1/20th of a second or less)
  • One connection can carry different services to
    your home,
  • so long as they all use the Internet Protocol
    (IP)

12
Streaming
  • Streaming is where you watch or listen to a
    program while it is being downloaded or uploaded
  • Packets are received, played, and discarded,
    instead of being saved to permanent storage (like
    a hard drive)
  • Streaming a high-resolution TV episode requires
    2mbps
  • Streaming a satellite-quality TV channel requires
    8mbps or more
  • Streaming upload of low-definition video (eg,
    video chat) requires .5 mbps or more
  • New services will require more bandwidth.
  • Streaming allows you to start watching or
    listening much sooner than if you had to download
    a whole program but you have to stream it again
    next time you want to watch it!

13
Bandwidth
  • The Bandwidth of your connection determines what
    content is usable
  • Upstream bandwidth determines how quickly you
    can send something for someone else to look at,
    read, watch, hear, or play
  • Downstream bandwidth determines how quickly
    your connection can receive something for you to
    look at, read, watch, hear, or play
  • Bandwidth packet size (in bits) packets per
    second
  • Download Download Start video
  • Speed Song Movie
    (Streaming) Upload Photo
  • 1mbps 36 seconds 1.6 hours 5 seconds 24 seconds
  • 10mbps 3.6 seconds 36 mins .5 seconds 2.4 seconds
  • 100mbps .3 seconds 3.6 mins .05 seconds .2

Wireless Analogy
  • Wireless communication is like talking in a room

17
Wireless Analogy
  • Wireless communication is like talking in a room
  • You can talk fast or slow (fast more BPS)

18
Wireless Analogy
  • Wireless communication is like talking in a room
  • You can talk fast or slow (fast more BPS)
  • Harder to hear if
  • Youre farther away
  • There are more people talking
  • Theres more background noise
  • Youre talking faster

19
Wireless Analogy
  • Wireless communication is like talking in a room
  • More data per second talking faster
  • Harder to hear if
  • Youre farther away
  • There are more people talking
  • Theres more background noise
  • Youre talking faster
  • You can break people up into groups
  • They can talk quieter and faster to each other
  • The groups leaders can talk to each other

20
Wireless Topology Options
  • Determines who can talk directly to whom

21
Wireless Topology Options
  • Determines who can talk directly to whom
  • Dependant on physical topology (distance,
    obstructions, etc)

22
Wireless Topology Options
  • Determines who can talk directly to whom
  • Dependant on physical topology (distance,
    obstructions, etc)

Compare Urbana (Tree City USA) to Manhattan
(big buildings)
23
Wireless Topology Options
  • Determines who can talk directly to whom
  • Dependant on physical topology (distance,
    obstructions, etc)
  • Dependant on radio characteristics (speed, power,
    congestion control)

Wireless Topology Options
  • Determines who can talk directly to whom
  • Dependant on physical topology (distance,
    obstructions, etc)
  • Dependant on radio characteristics (speed, power,
    congestion control)
  • Options
  • Star (aka hub and spoke)
  • Mesh
  • Volo

25
Star topology
Internet
CPE (Customer Premise equip.)
2.4 or 5.8ghz radio signal 2-30mbps
Radio Tower
RJ45 Ethernet Wall Jack
Customer Site
Customer Site
2-5 Mbps Ethernet Link
Customer Site
26
Star notes
  • Cheap
  • Simple
  • BUT
  • Doesnt scale well (gt100 users)

27
Mesh topology
Internet
CPE (Customer Premise equip.)
Customer site
RJ45 Ethernet Wall Jack
Customer Site
Customer Site
2-5 Mbps Ethernet Link
Customers access net through other customers
Customer Site
28
Mesh notes
  • Organic
  • Low overhead
  • Community brownie points
  • BUT
  • Very inefficient (slow)
  • Unpredictable (who is offline if a customer
    quits?)
  • Short range (no towers)

29
Volo topology
Umbrellas of coverage
30
Volo notes
  • Hierarchical cellular design
  • Low overhead initially
  • Wide coverage
  • Unlimited scaling
  • Predictable coverage
  • BUT
  • More towers

Overview
  • About me and Volo
  • How Volo works
  • How the internet works The big picture
  • Wireless last mile
  • Volo Topology
  • The Federal Stimulus Package
  • The rural digital divide
  • Champaign County Backbone
  • Champaign County Volo
  • Discussion

32
The Federal Stimulus Package
  • 7.2 billion of Federal stimulus money is set
    aside for broadband
  • Targeting unserved (no internet) and underserved
    (slow internet) areas
  • Collaboration with and letters of support from
    Cities, townships, increases the likelihood of
    being funded
  • Applications submitted in August, grants will be
    awarded in December

33
The Rural Digital Divide
  • Infrastructure costs money
  • Time costs money
  • Rural areas have few people per unit area
  • Fewer people per infrastructure dollar
  • More wasted in support logistics
  • Service providers make up costs with high rates,
    up-front charges
  • gt Rural areas make less , gets less
    infrastructure, and has high barrier to entry

34
Volos solution CCBB
  • Champaign County Broadband Backbone
  • Bring C-U backbone resources to towers in rural
    areas
  • Requires a fiber backbone and 17 towers around
    the county
  • Goal encourage local providers to service rural
    areas, provide better connections to schools
  • Cost 1.5M for all of Champaign County
  • CCBB gt Lower infrastructure costs gt better ROI
  • Local providers gt lower support costs

35
Volos solution CCV
  • Champaign County Volo A CCBB proof of concept
  • Deliver connections from the towers to households
    in rural areas
  • The speed of the service would be 5-25/mbps
  • Cost per household with stimulus 45/month
  • Cost per household without stimulus 300-500
    Installation plus 45/month
  • Goal Subsidize initial investment for 1200
    subscribers, to allow future subscribers to have
    0 up-front cost
