IWCE Conference: Mesh 101 Pres

  1. 1. March 2009 Mesh Networks 101 – Advantages and Uses College of Technology Track, Tues, March 17, 8:00 am - 12:00 pm (4 Hours) Martin Suter, VP, Business Development, BelAir Networks Lokesh Bali, Richmond CA Police Department
  2. 2. mesh is not a market
  3. 3. mesh is not muni
  4. 4. mesh is a technology
  5. 5. Suter’s definition of a mesh network: A flat network topology comprised of picocells, each of which with integrated, redundant backhaul, and capable of relaying data over multiple hops
  6. 6. How did I end up at IWCE talking about mesh networks 101?
  7. 7. In the past 8 years, I’ve… • Worked for 5 “mesh” companies • Been on both the “buy” and “sell” side • Evangelised both proprietary & standards-based approaches • Met with most companies in the industry, large and start-up, from chips to systems • Worked with the earliest adopter customers • Been to all the conferences, talked to all the analysts • Seen what has worked, and what hasn’t
  8. 8. Once upon a time… …a technology is announced that generates significant press and industry interest.
  9. 9. There’s a period of over-enthusiasm and unrealistic projections, a flurry of well-publicized activity by technology leaders…some successes, but more failures… The only enterprises making money are conference organizers and magazine publishers.
  10. 10. Because the technology doesn’t live up to its over-inflated expectations, it rapidly becomes unfashionable. Media interest wanes, except for a few cautionary tales.
  11. 11. However, focused experimentation and hard work by an increasingly diverse range of organizations lead to a true understanding of the technology’s applicability, risks and benefits…
