IMPROVED BROADBAND
COVERAGE TO CITIZENS
GREEN - REDUCES
POWER CONSUMPTION
BLENDS IN WITH THE
ENVIRONMENT
SAFE – NOT SIGNIFICANTLY
DIFFERENT THAN Wi-Fi
• Improved in-building
coverage
• Improved network
capacity
• Eliminates dead-zones
• Lower transmit power
required
• Reduce macro power
• Greater signal strength at
lower UE power
• 70% less power than
macro cells
• Smaller footprint
• Lower UE power
consumption
• More aesthetic then macro
towers
• Unobtrusive – “blends in”
• Installed in discreet
locations
INDUSTRY REQUIRES: 1) DEFINED GUIDELINES, 2) FAST TRACK PERMITTING, 3) TRADE ASSOCIATION PROMOTION

CHALLENGE
Automation is vital for metro scale
Multi-Vendor SON available today
No need for rel-10 to launch HetNet
Some multi-vendor Rel-10 features
(COMP, eICIC) will require S1/X2 IOT
Industry collaboration is needed for X2 IOT.
Join us in making this happen!

REALITY
MELBOURNE FESTIVAL 2012 - THE DERBY, CUP, OAKS, AND STAKES DAY
GOOD PERFORMANCE IN A CHALLENGING MULTI-VENDOR, MULTI-LAYER, SHARED CARRIER HETNET
• Deployment of 7 lightRadio™ Outdoor Metrocells in
Multi-Vendor environment
• Macro: 2 x 850MHz W-CDMA, 3 x 2100MHz W-
CDMA
• Metro cell: Shared Carrier 2100MHz W-CDMA
• Metro cell provided good coverage and performance
despite high capacity. Traffic offload increased during
event due to higher performance of small cells
- >262K PS and 8.7K CS calls
- High aggregated DL throughput of 1 Mbps
- 95% PS success rate on Derby Day
- 98% CS call setup rate on Cup Day
- 98% metro-metro Handover
