Wireless Backhaul
    Brian Hollister
        Increased Bandwidth Demand at Cell
                      Sites

• Leased backhaul lines account
  for as much as 25 percent of
  some mobile operators’
  operating expenses
• New architectures and
  applications will require double
  the bandwidth in the near term
  and the demand for more
  reliability is skyrocketing
    – Wireless Data: CDMA, HSDPA,
      & EVDO
    – Applications: IM, Video, gaming,
      etc
• ILECs faced with meeting this
  rapid demand cost-effectively in
  order to stem competitive
  encroachment
       Hurdles Associated with Fiber Based
                    Ethernet

• Ethernet posed to be best alternative for mobile
  operators…problem is ILECs have limited fiber
  deployments to cell sites
   – <10% of the 140,000 cell sites in the US have direct fiber
     connectivity
• ILECs struggle with marginal increase in incremental
  revenue and high cost of fiber deployment for optical
  based Ethernet
• Average fiber build out (e.g. trenching) can cost $50 –
  200K, depending on the terrain and distance involved
  and right-of-way issues
• Solution: ILECs will need to leverage their existing
  copper assets and utilize broadband over copper
  technology
               Broadband over Copper (BBoCu)
                         Backhaul

•   Aktino & customer win Globalcomm award for innovative cellular backhaul solution
•   Case Study:
     –   Site fed by 7 DS1s with no additional available copper and required an significant
         bandwidth upgrade
     –   Fiber build out was to costly to ILEC and the build out wouldn’t meet customer
         timeframe
     –   Aktino’s MIMO on DMT technology was installed in hours on the same 14 pairs that the
         previous 7 T1s used and provided capacity for a full DS3 (28 T1s and/or 50Mbps
         Ethernet on 14 pairs)
                                                14 Pairs @ 12Kft Feet

                   Summary

• Carrier class Ethernet posed to be best
  alternative for cell site backhaul
• Limited deployment of fiber and high cost of new
  deployment will limited Ethernet availability for
  years
• ILECs will need to leverage existing copper
  infrastructure in order to stem competitive losses
• BBoCu solutions provide ILECs with a tool that
  provides significant increases in bandwidth and
  reliability at a fraction of the cost of fiber
