Key Factors in Backhaul Deployment
• Equipment plus Installation must meet market targets
• Equipment needs to provide services in a few hour, not weeks or months – with minimal planning and licensing
• Drive down ever increasing antenna lease and spectrum costs along with radio equipment site costs
• Must be enough for Backhaul Requirements of today and tomorrow – with an established capacity roadmap

Cost comparison: various backhaul technologies
•Forecast cost to transport data traffic: as traffic increases, the need to build or upgrade backhaul increases
•Voice traffic is assumed to be carried on E1•Cost increases towards the end of the forecast period due to volume of traffic•Deployed Fibre is second most expensive but is a long term option for some operators•Microwave technologies are the most cost efficient

WHAT ARE THE COST IMPLICATIONS?
Evaluating last mile backhaul for European Operators
Slide 12In ConfidenceCambridge Broadband Networks Ltd.
Mobile operators want backhaul solutions that cost less,
deliver higher performance and reduce the complexity of
their networks
Slide 13In ConfidenceCambridge Broadband Networks Ltd.
Cost comparison: Tier-1 UK Operator
The analysis presented has been undertaken for an international Tier-1 operator running a mobile broadband network in the UK. Calculations are for a 5-year period.
• Cost savings of PMP compared with TDM/fibre leasing for the total cost to transfer traffic amounts to US$497 million per year during 2010, increasing to US$2.8 billion per year for 2014
• PMP is expected to offer cost savings of US$26 million during 2010 and this will increase to US$248 million during 2014 compared to PTP microwave.
Source: Informa Telecoms & Media
• Cost comparison (Europe) between PMP and the other two prominent technologies, PTP and hybrid fibre (leasing)
• Although both leasing fibre and hybrid backhaul technologies are considered cost-efficient, analysis shows that PMP can provide better cost savings in backhaul, even compared to the widely established PTP microwave in Western Europe.

IS THERE A ANOTHER WAY?PMP Microwave Backhaul

Point-to-MultiPointPoint-to-point
PMP Microwave Architecture
PMP uses 1 frequency per sector. To backhaul 9 cell sites, VectaStar uses 8 fewer radios:10 vs. 18
Access point
PtP uses 1 frequency, 2 radios and requires 2 installations per
link
Single Hop = predictable latency

150MbpsSectorth’put
Stat-Mux and Aggregation
Point-to-Point backhaul planners have to provision for peaks, i.e. 30Mb/s per NodeB:
120Mbps
VectaStar aggregates cellsite traffic in sector
Built-in optimisation and statistical multiplexing reduces peak backhaul
requirement to 40 Mbps
Total provisioning: 4 x 30Mbps = 120 MbpsPTP: Bandwidth not used is wasted!

Case Study: LTE Network London
LTE PMP Backhaul solution for London:• 145 Cell sites• 8 Hub sites• 150Mb/s Peak• 30Mb/s Mean
Utilises overlapping sectors to increase capacity in dense, high traffic areas
Comparison showed that at 100Mbps, PtP exhausts available spectrum.VectaStar used less than half the spectrum needed for PtP
Slide 19In ConfidenceCambridge Broadband Networks Ltd.
VectaStar CAPEX advantage compared to Implemented PtP from 2 links:
Point to Point is 40% more expensive at 5 links Point to Point is 80% more expensive at 15 links
Deploy PMP Access Point Network for Lower Capex than PtP - AND save on OPEX
