Is your network PhaseReady?

attend the Phase Ready Seminar from Chronos

Phase Ready?

As you think about the evolution of your network, don't limit your thoughts to the frequency stability you need now. We want to help ensure that network roll-outs today will still be relevant come the explosion of HetNets and Small Cells.

Free PhaseReady Event - London, Wednesday June 3rd

Registration is now open for the latest PhaseReady event at Kings Place London on Wednesday June 3rd. This is the latest in our series of events at this excellent venue, addressing the challenges and solutions available for timing in next generation networks as these networks, services and applications have evolved.

Entitled "Supporting Your Phase Network", we will be discussing the keys areas of preparing for, planning, testing, rolling out and monitoring your timing network to reliably deliver microsecond phase to the edge of your network.

We will be joined for keynote addresses from industry expert Zahid Ghadialy, Transmode's Hans Sjöstrand and Microsemi's Simon Butcher.

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.”

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!

Join us at 'Phase Ready' in London on 8 May and win an iPad mini

Join the sync experts from Chronos and Symmetricom and Industry Keynote Prof Simon Saunders and Operator Keynote Martin Kingston of Everything Everywhere at Chronos’ complimentary event in London 8 May 2013 to find out if your network is phase ready.

The migration from SDH to Carrier Ethernet continues; moving from the “certainties” of SDH timing to PTP and Synchronous Ethernet.  Now we see the next timing challenge on the horizon – PHASE synchronisation at the network edge.  And the key driver for this requirement is not that networks will be using Time Domain transport technologies like LTE-TDD, but the coming of LTE-A, Heterogeneous Networks (HetNets), Small Cells, Enhanced InterCell Interference Coordination (eICIC) and Coordinated Multipoint (CoMP).

There will be an opportunity to win two Apple iPad minis supplied by Chronos and Symmetricom.

Why Phase Ready?

Many of us have been, and are still, involved in the migration from SDH to Carrier Ethernet in networks; moving from the “certainties” of SDH timing to PTP and Synchronous Ethernet. The crossing of the “Bellhead / Nethead” boundary has mostly got beyond “Ethernet doesn’t need sync” and, in a surprisingly short period of time, getting good frequency performance to the edge of networks over Carrier Ethernet is just about done.


Now we see the next timing challenge on the horizon – PHASE synchronisation at the network edge. And the key driver for this requirement is not that networks will be using Time Domain transport technologies like LTE-TDD, but the coming of LTE-A, Heterogeneous Networks (HetNets), Small Cells and Enhanced InterCell Interference Coordination (eICIC).
It’s a given now (or seems to be) that in next generation mobile networks the Macro layer will simply not have the coverage and spectrum to deliver data densities and rates customers now require. The latest Small Cells Market Data white paper from the Small Cells Forum looks at the scale of likely rollouts. For example “Mobile Experts published a new forecast claiming that 70 million small cells will be shipped by 2017, including Femtocells deployed by mobile operators and picocells used for high-capacity urban networks. LTE small cells are a major part of the forecast growth over the next five years, with more than two-thirds of small cells deployed in 2017 devoted to LTE-FDD or TD-LTE.”


A blog post from leading industry consultant Frank Rayal called “More and More Small Cells, But Where’s the Gain?” notes that “In the absence of advanced interference management solutions, most capacity benefit will be obtained from deploying small cells in a targeted way with intimate knowledge of the location of traffic hotspot and interference profile. In other words, forget about mass uniform deployments for now. Planning will remain essential.”


Effective eICIC requires stringent phase synchronisation between deployed Small Cells and the Macro cell(s) under which they operate. And effective eICIC will be the tool to enable “mass uniform deployments”. This requirement and the issues around it are why we’ve launched phaseready.com.
