Increased Bandwidth Demand at Cell SitesIncreased 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
21
Hurdles Associated with Fiber Based Ethernet 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
22
Broadband over Copper (BBoCu) BackhaulBroadband 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)

Ethernet Broadband over Copper: SummaryEthernet Broadband over Copper: 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
