    6. 6. MARKET CYCLES
    7. 7. Does this story resonate? Once upon a time, a technology is announced that generates significant press and industry interest.
    8. 8. Does this story resonate? Once upon a time, a technology is announced that generates significant press and industry interest. 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.
    9. 9. Does this story resonate? Once upon a time, a technology is announced that generates significant press and industry interest. 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. 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.

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. 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.

Broadband Access with Integrated Backhaul <ul><li>High capacity wireless microcell network </li></ul><ul><ul><li>Wi-Fi access today </li></ul></ul><ul><ul><li>LTE & WiMAX tomorrow </li></ul></ul><ul><li>Flexible and Easy to deploy </li></ul><ul><ul><li>Cable strand mounts, multiple pole mounts </li></ul></ul><ul><li>Industry leading capacity </li></ul><ul><ul><li>Patented multi-radio switched mesh backhaul </li></ul></ul>
    71. 71. Thoughts on Unlicensed Spectrum <ul><li>Spectrum is a valuable and scarce resource </li></ul><ul><li>FCC has allocated 4 significant bands as “unlicensed”, effectively an RF Commons </li></ul><ul><ul><li>~80 Mhz @ 2.4GHz (ISM band) and ~450Mhz @ 5.xGHz (the UNII bands) </li></ul></ul><ul><li>FCC Part 15 regs dictate use (i.e. max EIRP), in an attempt to equitably share the commons </li></ul><ul><li>2.4GHz is particularly dirty, with potential interferers like microwave ovens, and its inherent propagation characteristics </li></ul><ul><li>Technologies have been developed to mitigate the challenges of operating in unlicensed bands </li></ul><ul><ul><li>Particularly effective in backhaul scenarios </li></ul></ul>
    72. 72. Unlicensed Spectrum: Access vs. Backhaul <ul><li>2.4GHz </li></ul><ul><ul><li>3 x 20MHz non-overlapping channels </li></ul></ul><ul><li>Low powered radios (battery powered handsets) </li></ul><ul><ul><li>~35mW typical </li></ul></ul><ul><li>Omnidirectional antennas </li></ul><ul><li>Associated with a single AP; no alternate routing </li></ul><ul><li>5.xGHz </li></ul><ul><ul><li>21 x 20MHz non-overlapping channels </li></ul></ul><ul><li>High powered radios (AC powered) </li></ul><ul><ul><li>1-4W EIRP </li></ul></ul><ul><li>Directional antennas </li></ul><ul><li>Mesh protocols re-route in presence of interference </li></ul><ul><ul><li>Adaptive modulation, packet-by-packet error detection, etc. </li></ul></ul><ul><li>Propagation characteristics work in your favour </li></ul><ul><li>Access </li></ul><ul><li>Backhaul </li></ul>Unlicensed for 4G backhaul is absolutely feasible

BelAir Key Conclusions <ul><li>Wi-Fi will remain a ubiquitous wireless broadband technology for access post-2015 </li></ul><ul><ul><li>Cellular handsets, music players, gaming devices, laptops </li></ul></ul><ul><li>Fixed-Mobile convergence & Mobile Internet are fast becoming “must have” by consumers </li></ul><ul><ul><li>Well-funded ecosystems are being built to fund and deliver rich mobile apps (Apple iPhone developers, Google Android, Windows Mobile, etc.) </li></ul></ul><ul><li>Proliferation of devices + rich content will require 2 orders of magnitude greater network capacity than exists today with cellular </li></ul><ul><li>ILECs, wireless carriers and cable companies are all vying for the same subscribers </li></ul><ul><ul><li>Lines are blurring with UMA/VoWLAN over cable; wireless broadband access vs cable and DSL; IPTV vs satellite and cable </li></ul></ul><ul><li>Microcell topology is required to deliver data rate and capacity for wireless broadband in densely populated areas </li></ul><ul><ul><li>Wi-Fi today, Wi-Fi & LTE in 2011 and beyond </li></ul></ul>
