5. 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

6. 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

7. 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

8. Managing Cell Capacity
Users
Trade-off between users served and average
data per user initially, then expand capacity as

9. 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 3G
LTE
WiFi
And achieving an efficient TCO

ActiveRadio® : femtocell fundamentals
Automatic cell setup
zero touch installation
ActiveCell
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.

12. Backhaul defines small cell hotspot experience
Installed in public places: cafes, malls, stores, rail stations, venues etc
Multi-technology: 3G, WiFi and LTE in one box
Key characteristics High quality mobile experience
Small cells provide high-speed,
short-range signal with low
contention
But Backhaul is the limiting factor
Limited capacity, heavily loaded with 3G/4G/WiFi traffic,
highly variable performance

13. Now add our computing platform
Strategic collaboration
between Ubiquisys and
Intel
Compact, comms-­‐tuned
compute platform
Core® and Atom® variants
available, with hardware
accelerators
40GB+ SSD and 4GB+ RAM
Accelerators CPU
An ultra-compact server with massive inline processing capability
