Kings Place - another successful day

Thanks to everyone who attended our Kings Place (@Kingsplaceevent) event yesterday. I think it was a great success and as well as provoking thought about how best to deliver phase to the edge of the network in an operationally supportable way, we also had time to debate the future of engineering!

Use of TDD spectrum also had a good airing; interesting developments in Japan at 3.5GHz could mean phase is essential not only to ensure you use your own spectrum efficiently, but that you don't compromise your competition!

Special thanks to our independent Keynote speakers Zahid Ghadialy (@zahidtg) from TechUK and Hans Sjöstrand from Transmode.

Small Cells World Summit - sync is creeping on to the agenda!

Had the pleasure of contributing to a panel discussion at the Small Cells Backhaul Summit at the ExCeL last week. We had half an hour on the topic "Time and timing distribution for small cells". My co-panellists were Martin Kingston, Principal Designer at EE and Richard Strike, Business Development Manager, Ethernet Access at ADVA Optical Networking; and it was ably moderated by Rami Yaron. The discussion really centred on getting phase to the edge of mobile networks, and how the business case stacks up to achieve this.

Now half an hour doesn't seem like much, and in fact the discussion could have gone on for a LOT longer, but it is half an hour more than last year's event! There were a lot of presentations in the Backhaul Summit that mentioned to various degrees how difficult getting phase to the network edge is going to be, but no real expansion on that at all.

I was pleased that my view of the world chimed pretty well with Martin's; I've known him for many years now and respect his judgement and so if we are in accord I know I'm doing something right! Interestingly the area where we parted company was an unexpected one for me. I've thought that Small Cells would be more expendable than Macro Cells, and that operators could probably stand availability levels less than the five-nines we're used to in the Core. Martin was quite clear that if it is on his network it needs to be available! This will have quite an impact on timing and backhaul technologies; and pose some interesting questions for Small Cell holdover capability.

Chronos participating at Small Cells World Summit: 10-12 June 2014

Chronos participating at Small Cells World Summit: 10-12 June 2014

Wednesday 11 June 2014, 11:50 at London ExCel

Steve Newcombe of Chronos is participating in the Panel Discussion: Time and Timing Distribution for Small Cells at the Small Cells Backhaul Summit at 11:50 hours on 11 June.  Topics include the latest developments in timing standards and what this means for small cells; how timing equipment affects the network architecture; ToD sync methodologies in cellular networks; strategies for delivering ToD accuracy at low cost in LTE and small cell networks.

Chronos’ extensive practical experience in deploying industrial grade GPS systems, traditional synchronisation networks and current research with indoor UTC traceable time using the new eLoran technology has helped us to understand the real challenges operators face as they move to deployment of LTE-A services.  Phase synchronisation between macro and small cells must be achieved if key services such as eICIC and CoMP are to operate effectively and reliably.  Chronos is now offering a new range of services designed to help network operators assess and prepare their networks for these new challenges as they prepare to rollout LTE-A services.

Chris Roberts, Strategic Marketing Manager at Chronos said, “Achieving precise phase performance at the edge of complex networks now requires planners and installers to have knowledge of Radio Frequency (RF) engineering. Anyone can install a cable from a GPS antenna to a Grandmaster clock to enable a green LED to light but it is far harder to find contractors with the RF engineering skills to ensure it will operate as expected in large scale, complex networks. Chronos has this experience; come and talk to us.”

Achieving phase synchronisation between macro and small cells

Achieving phase synchronisation between macro and small cells

Phase synchronisation between macro and small cells must be achieved if key services are to operate effectively and reliably.  With over 25 years’ experience in industrial GPS systems and network timing solutions, Chronos has now developed three services to help operators assess and prepare their networks for these new challenges.

PhaseReady™ Design and Test: A consultancy service that has already been deployed in a number of equipment manufacturers helping them prepare their products for the market. The service is tailored to meet the objectives of the client and a recent example was a study of the impact of enabling SyncE to support PTP timing transfer.

PhaseReady™ Core: A service that uses advanced tools to assess the suitability of existing GPS / SSU / Grandmaster system locations to supply phase aligned timing signals into the network for distribution.  In-house developed testing methodologies combined with the use of tools including TimePortTM to ensure the phase performance of key GPS sites is properly engineered.

PhaseReady™ Network: A service that works with network planning and operations teams to assess how best to engineer the sync distribution within the network so that the application performance requirements are met. This service identifies the design decisions and parameters in the network that may or are affecting the delivery of good enough phase to the application that requires it.

Small Cells World Summit Report - David Chambers

Good overview of the Summit from Think Small Cells's David Chambers HERE. Particular interest for me in the embedded video of interviews David conducted is Todd Mersch of Radisys talking about the two key areas that will be exploited from LTE-A. Todd can of course speak for himself but the two areas he identified - Carrier Aggregation (CA) and SON / Interference Mitigation - will have stringent phase sync requirements!

First Small Cells Backhaul Summit a success

Just back from the Small Cells World Summit and decided to sit in on the whole of the inaugural Backhaul Summit track. Had to sit on my hands at times to not ask the "what about phase sync?" question, but I was pleasantly surprised that there was some awareness at least of the challenges coming our way.

Some very interesting battles to come in the sub 6GHz non line of sight area if the debates at this summit were anything to go by!
