Small Cells Deployment Scenario Examples
Macro site issues
•
•
Site cost, availability, leadtime for new site
Site is too far from optimal
location
RF Regulation
•
Safety / Health regulations
limit the transmitted power
Strategic Areas
•
•
High ARPU subs satisfaction
is key
High roaming revenue area
(event, airport)
Urban Fill-in
>
Street canyons, street
corners, tunnels,
underground car parks
Public Indoor
•
Transport links, shopping
malls, etc…
Rural / Sub-urban
>

Cellular tower or pole is not
accepted by authority
community
New macro site is overkill
Enterprise
•
Enterprise customers
buildings guaranteed QoS
Compulsory Coverage
>
Universities, Hospitals,
Government buildings, etc…
Hot Spot / Hot Zones
•
Macro sites cells capacity is
not enough
Protected Buildings
South Europe – Special events performance
Capacity Underlay / Improve experience @ the event
Set up
• 5x FZ Micro/Pico @ 2.6GHz deployed as underlay in the event
• LTE Competitor Macro underlay @ 1.8GHz (5 sectors covering the area)
• Hot Spot type deployment – Ratio of 1 FZ / macro sector in that area
• FZ ISD 20m to 150m with RF Power 250mW (cell range ~30m) to 5W (cell range ~120m)
