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 access femtocells 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 Café 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 café in a business district, where people get their coffee and immediately fire up their browser or social network page

Trade-off between users served and average data per user initially, then expand capacity as needed

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


Ubiquisys G7 series Multi-mode Small Cell

3G LTE WiFi

Automatic cell setup zero touch installation


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 spikes of 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 factor Limited capacity, heavily loaded with 3G/4G/WiFi traffic, highly variable performance

High quality mobile experience Small 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 Key characteristics
