Metro Indoor: the small cell sweet spot

Acute growth in data demand

from smartphones Abundant sites and backhaul

Key Asian city deployments in

malls, coffee shops and

transport hubs

50,000 public access small

cells deployed

200,000 open accessfemtocells deployed

Example Metro Indoor hotspot stats

Smart phones up to 90% of phone types in cell

Traffic dominated by data/signaling Channel occupation data/voice - up to 10 to 1

Data sessions in 24hrs up to 10,000

Voice sessions in 24hrs up to 1,000

Average UE voice traffic up to 70mE

Average UE data traffic up to 200mE

Data dominated by chatty

smartphone apps

Signaling procedures per UE in

Busy Hour

up to 50 per user

Highly transient users

Average time in cell

- from 7mins to 30 mins

Smartphone traces Caf hotspot

Macro cells average traffic in a medium/large size area, while a small cell covers a specific area

where traffic is heavily correlated.

Example is of a caf in a business district, where people get their coffee and immediately fire

up their browser or social network page

The challenge for public access small cells

The challenge IS NO LONGER about headline data rates or call

capacity.

The challenge IS ALL about meeting network KPIs in a highly

variable high traffic environment:

Cell overloading

Camp-on attempts

Data vs signalling

And achieving an efficient TCO

ActiveRadio : femtocell fundamentals

Open Mode operation

Automatic cell sizing:

preserves the target quality of service in hotspots.

Loaded cell adaptive radio resource management:

continuous monitoring of the radio environment even while

serving active users.

Hotspot robustness:

ensures the best possible quality of service during high spikesof transient users.

Edge processing of smartphone signalling :

to significantly reduce the load on the core network.

Backhaul defines small cell hotspot experience

But Backhaul is the limiting factorLimited capacity, heavily loaded with 3G/4G/WiFi traffic,

highly variable performance

High quality mobile experienceSmall cells provide high-speed,

short-range signal with low

contention

Installed in public places: cafes, malls, stores, rail stations, venues etc Multi-technology: 3G, WiFi and LTE in one box

Summary

Small Cells come in many flavours for different use cases

Home Femtocells, Enterprise Small Cells, Metro Indoor, MetroOutdoor and Rural

We need Metro Indoor and Outdoor to meet the data demand

As proven in Asian Markets already

Optimised Femtocell based technology 3G/LTE plus WiFi willdeliver the majority of Small Cell segment needs

Smart Cells

Optimise the end user experience

Optimise the backhaul performance Offer new Edge Cloud opportunities for Service providers
