The smart phone paradigm
Impact of Data growth
Evolving our Network
L.T.E London Trials 2011
Key thoughts
Dave Owens speaking introducing

3. Apple Re - invents the phone in 2007!
Every once in a while a revolutionary product comes along that changes every thing!
Wide screen iPod with touch control
Revolutionary mobile
Break through internet communication device
iPod + Phone + Internet are you getting it!
And they called it the iPhone
Apple had reinvented the phone, and we all know that now.
Key to Apple’s success was it made the iPhone both easy to use and smart

4. The Perfect Storm…
The iPhone made using the internet really easy and fast…
Break through App Store started to give customer easy ways to tell there friends what they were up to.
Coupled with all you can use data tariffs
Social Networking was born
This created a storm of access attempts
And lots and lots of traffic 

5. Smart phones are driving radical data traffic growth
Date Traffic Grew really fast ~33 times since June
Data Traffic continues to growth at a pace, doubling approximately every 6 months

6. Impact on the London network 2009
Data traffic growth started to impact voice calls…
Data performance falling below target…
We were receiving negative comments in press
Customer satisfaction levels questioned
O2 wanted to give our customers the network they deserved
We needed to get the right capacity in the right places for our customers.

7. Advanced thinking in 2009 – the smart phone paradigm shift
Capacity enhancement strategies
• Deploy 3G Microcells
• Upgrade sites to 6 sector
• WiFi offload approaches
Device insight
Understanding ‘hostile’ device behaviour (e.g. Fast Dormancy, poor RF sensitivity of iconic devices)
3G experience awareness
New customer-centric statistics to identify challenged sites
Using ariesoGEO to pinpoint data hotspots from within the network geography
Infrastructure pinch points
Resolve BTS & RNC pinch points with vendors
Roll out next generation of BTS

8. Pioneering new Offload strategies…
New solutions allow us to understand traffic & performance to a building resolution. Data traffic hotspot at UCL student lodgings.
First UK operator to rollout 6 sectors sites: 40% capacity uplift, 25% more connections
Microcell must be close to the source of traffic, giving 250% capacity uplift per square kilometer
Understand & solve complex areas, challenging radio environments
Huge flow of people at rush hours
High numbers of VIP corporate customers
O2 task force established– trialling new ways of working.
Nominated for 2010 Global Telecoms Business Innovation Award.
The programme continues to push new boundaries…

11. O2UK Radio Network 2013 (Heterogeneous 3G/4G)
Busy areas require 50m radius microcells
All microcell deployed with 4 carriers (2xU2100, 1xU900 & 1xLTE2600).
Limited to 7 macrocells within 1x1km area
Busiest 200x200m area requires 6 microcells plus 3 carrier picocells/public femto cells
Microcell range limited to 150m due to building loss and corner loss

12. Small Cells, Femtocells & Wi-Fi
Small Cells are required to cope with x5-10 capacity requirements
2011: O2 Wi-Fi – Free Public Wi-Fi deployment
2011: VIP/SME Femtocell Pilot, Corporate Trial
2011: Metrocell (Public Femto, Street Furniture 3G/4G Trial)
2012: Metrocell deployment

13. Preparing for The Mobile Data Olympics How we’ve tackled it
Target: Increase Twickenham bowl coverage from 4 to sector (x10 capacity)
Twickenham Rugby Stadium, West London is our Proving Ground.
Solution: Higher order sectorisation within Stadia - another first in the UK
Result: A template from which we can confidently build high capacity solutions at all key Olympic venues

14. LTE London Operational Trials 2011
O2 Femto
Smaller cells for 3G are the future. Backhaul is the problem. LTE to be trialled as a solution to small cell (2G/3G/4G) backhaul.
Friendly Users
LTE trial will allow backhaul of O2 Wi-Fi hotspots in All they’ll need is a power socket (literally plug & play)
Target high data uses/corporates in Central London to offload data from 3G
LTE is the future, but handsets/traffic will take time to come.
However can make it sweat from day 1 and offload our 3G network through novel 2G/3G offload techniques as described above - to be trialled in 2011

15. O2 network coverage
The same comments as the previous slide.

16. It was nice to get a pat on the back, but the hard work continues…

17. Key thoughts Apple did reinvent the Phone…
Smart phones, App & Social Networking have changed the mobile industry forever…
3G will continue to evolve to deliver faster speeds – but user experience is key
Location-aware data provides customer-centric decision making & network performance maximising network investment
Need to push the technical boundaries for ours customers
We now have new technology to take our performance from cell level to building resolution, and this will be key capability for the future data needs of our customers… 17
