And the industry is prepared Or is it ?

Small cell per macro forecast, 2013-15

So…

HOW FAR CAN WE STRETCH ?

• How does VoLTE change the game?

• How will on demand video affect customer experience?

• How does mobile cloud computing affect device + network dependency?

40%of advance mobile broadband users will churn in the next 12 months

The Quality of Experience will be the key differentiator for converged operators

COVERAGE, CAPACITY, COST: “THE 3Cs”

• Elastic Backhaul Coverage:– Be able to cover a wide area with a

single radio unit to prevent overcrowding

– Be able to extend the range of your backhaul coverage easily through relay nodes

COVERAGE, CAPACITY, COST: “THE 3Cs”

• Elastic Capacity:– Supply more capacity than demand– Be able to scale capacity as demand

grows– Look at providing at least 10x more

capacity than existing wireless backhaul solutions

COVERAGE, CAPACITY, COST: “THE 3Cs”

• Elastic Cost:– Pay as you grow business models

will be required– Be not only capex but opex efficient– Minimise installation, site rental

and operational costs with compact units that can generate area coverage

Fibre• The ideal backhaul

solution

• Penetration limited to 20-50%, typically urban coverage with issues over trenching and slow deployment

• This directly impacts on operator revenues and time to market

• Ideally suited for low-medium capacity

• Delivers required capacity (>100Mbits guaranteed) to sites at a good Capex

• 70-80% network coverage driving a large Yearly Opex

• PtP Evolved e-Band 60-90 GHz bands

• Block spectrum allocations to deliver increased link capacity

• Still have the same PtP Opex concerns as existing PtP MW

• 1st Generation PMP, fast time to market in 10.50/26/28GHz

• Filled the short term gap in 2G/3G deployments to max revenues

• Now not enough capacity for 4G

• 2nd Generation PMP technology 42GHz offers 1GHz radio

• Scalable 2Gbit sector capacity with 100-400Mbit Terminal capacity

• Delivering PtP capacity within PMP architecture

• Predicting demand in network planning is increasingly difficult

• Service providers’ backhaul solutions need to stretch across all the sites that will need it, with no compromise in performance, coverage, and total cost of ownership

• HetNets are here, and will continue to evolve• A solution is required that can:

– easily extend gigabit coverage– allow providers to plan and delivery for peak cost effectively– Seamless integrate with small cells, wifi offload strategies

• This will enable converged service providers to cost effectively deliver massive network capacity with no compromise on customer experience
