Amit Jain, VP Product Management at Spidercloud, explains the various small cell alternatives for enterprise small cells suitable for SOHO, SME and larger businesses. He argues that as the number of enterprise femtocells/small cells increase, more local control is required. Various solutions from individual small cells (femtocells) through to large scale DAS (Distributed Antenna Systems) all have a place to play.

Enterprise customers constitute 15%
of subscribers, 30% of revenues
Small cells expected to be 18% of RAN

8. Seven Considerations for Designing an
Enterprise RAN with Small Cells
1. Seamless mobility
2. Consistently high throughput
3. Enterprise-centered management
4. Self-organizing and rapidly deployable
5. Efficient use of backhaul
6. Local switching of voice and data traffic
7. Scalable – from small business to campuses

9. Two Architectural Approaches
1. Using Core Network Based Controller: three variants
1. Enterprise femtocells with hard handover
2. Enterprise femtocells with soft handover
3. Pico cells with soft handover
2. Using a Local controller in the Enterprise

10. Enterprise Femtocell with Hard Handover
Viable for few small cells in an enterprise if end user is willing to tolerate call drops
and does not need consistent throughput. Locally switched voice/data calls drop if
user moves from one enterprise femtocell to another.

11. Enterprise Femtocells with Soft Handover
Support soft handover to offer seamless mobility and consistent throughput but
requires more processing power per small cell and more backhaul bandwidth.
Local switched voice/data calls drop during handover. Scalability unknown
because this architecture has not been deployed.

12. Pico cells with RNC in the Core
Enterprise pico cells use soft handover to offer seamless mobility and interference
coordination. However, this architecture does not scale because it places very
stringent requirements on backhaul and does not allow SON. Local switching is
not possible because the RNC is in the core.

13. Small Cells with Local Controller in
Enterprise
Offers seamless mobility and interference management using soft handover, optimizes
backhaul utilization, enables local switching of voice and data, and provides enterprise-
centered management. Self-organizing features make it possible to offer service in
very large enterprises in weeks, not months.
