Interoperability of Small Cells & the existing cellular networks - What’s the hold up?

Brought to you by The Small Cell Group

Small cells are proliferating in their many forms. To become a true part of the HetNet they need to be automatically and smoothly incorporated into the existing macrocell network, raising questions of standards, interoperability and performance.

Registration for this event is now closed.

About the event

3G femtocells created the first fully open interface in cellular history, with Iuh providing both control/data functionality and a management protocol on open standards. Plugfests and individual operator efforts have built on these foundations. Yet experience shows that there is a big gap between open standards and open interoperability, with a true multivendor environment still not being at anything like the level of, say today’s DSL modems. Is such open interop possible, or even desirable at this stage in the market?

While operators have called for interoperability between LTE metro/microcells and the macrocell network, the X2 interface has many different incarnations so a true open standard is not in place. Many vendors have small cell implementations which require tight coupling between their macrocells and small cells, sacrificing interoperability for claimed performance benefits. Operator initiatives have instead sought third-party SON ‘glue’ to unite the macro and small cell layers. Another level of interoperability is provided internally via interfaces such as FAPI (Femto Application Platform Interface) which aim to help vendors deliver consistent interactions between individual small cell subsystems.

Held at PwC London offices and kindly sponsored by Microlease & Keysight Technologies, this insightful half-day event will explore the need for interoperability, highlighting both the potential benefits and the associated sacrifices from both an operator and vendor viewpoint. It will capture current best practice, current challenges and chart the needs for the future. As with all CW events, there will be ample networking opportunities.

Small Cell/Macro Interoperability in the RAN: Impossible Physics, Hard Design or just Red-Tape?; Nick Johnson, Chief Technical Officer, ip.access

• Some anecdotes from history – interoperability failures on Abis, Iu-b, Load balancing with picocells –
doing it right this time
• Beyond standards – NGMN, SCF and other interoperability initiatives
• Buridan Telecom – a cautionary tale
• The schizophrenic vendor – can I protect my incumbency and attack the incumbent without
contradicting myself?

Progress Towards Maturing the Small Cell Multi-vendor HetNet Proposition; Neeraj Gupta, Senior Manager, and Kreso Bilan, Telecommunications Systems Architect, NEC UK

Through 3GPP, Small Cell Forum, ETSI and NGMN collaboration the industry has established the critical
interfaces and best practices necessary to gain interoperability proof points in multi-vendor HetNet
deployments. This was recently demonstrated by the successful completion of a plugfest in July, involving a broad range of macro and small cell eco-system vendors. Neeraj and Kreso, as chairs of core working groups responsible for providing direction to these activities within the Small Cell Forum, will highlight the challenges that have been overcome, and those that are still to be addressed.

How well do Small Cells fit within Heterogeneous Management Solutions?; Phil Claridge, Chief Innovation Architect, JDSU UK

This talk will explore the extent to which operators can gain a good planning and operational insight into their small cell networks (both licenced and unlicensed). The talk will focus on management solutions where the small cell network contributes to single view of a larger heterogeneous network, with a strong focus on per subscriber experience rather than just equipment and network health. Will include a perspective on the information that can or cannot be recovered from operational networks contrasting standards, vendor Implementations, and future mature solutions.

Evolution or Revolution of Interoperability for Small Cell; Alessandro Bovone, Senior Manager, Network Strategy, EE

What does interoperability mean in a small cell environment? Can a mobile operator afford the challenge to manage a multivendor environment and maintain on the small cell layer the level of customer experience that is now achievable on macro cell?
