Slide 8
Cost comparison: various backhaul technologies
Source: Informa Telecoms & Media
•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

Slide 11
Mobile operators want backhaul solutions
that cost less,
deliver higher performance
and reduce the complexity of
their networks

Slide 12
Cost comparison: Tier-1 UK Operator
• 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.
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.

PtP uses 1 frequency, 2 radios
and requires 2 installations per

PMP uses 1 frequency per sector. To
backhaul 9 cell sites, VectaStar uses
8 fewer radios:10 vs. 18

Slide 16
Stat-Mux and Aggregation
Point-to-Point backhaul planners have to
provision for peaks, i.e. 30Mb/s per NodeB:
Total provisioning: 4 x 30Mbps = 120 Mbps
PTP: Bandwidth not used is wasted!
Traffic measurements from
4 HSPA Node Bs in a
VectaStar network sector
VectaStar aggregates cellsite traffic in sector
Built-in optimisation and statistical
multiplexing reduces peak backhaul

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
