Small Cells World Summit 2017 Summary


I realised that I never got round to writing a summary post for Small Cells World Summit 2017. In fact I was waiting for summaries for various publications before writing a post but there was much less coverage this year.

Having said that, there were reasonable number of operators and most major vendors present. Small cells have sort of gone mainstream from their niche as many operators are now talking of small cells for 5G (mainly higher frequencies).

Anyway, here are some links with what I found interesting that you can explore further.

Here are some things ThinkSmallCell reported. Full report here:

SCWS, now in its 9th year, remains a regular feature of the small cell calendar. Now a two day conference, attendance was lower than some years ago but stable with noticeably more system integrators/installers actively participating. There was a little more focus on business enablers rather than technology this year, addressing deployment issues and neutral host opportunities for enterprise, urban and rural sectors.
...
The scope of SCWS is intended to embrace all of Small Cells, DAS and (Public Access) Wi-Fi. We saw one or two more DAS vendors participate but there was relatively little public Wi-Fi content. Perhaps that reflects the limited interest for that in Europe, as we saw at the recent Wireless Broadband Congress. The program included a few keynote speakers from operators (EE, O2, ATT, KDDI, Softbank) and some industry verticals (AEG, which operates the O2 dome and other stadiums; Grange Hotels etc.)       

Many mature small cell products are available today for both 3G and LTE. Form factors continue to shrink, software is becoming further automated and refined. The backhaul conference stream has been dropped with CCS now the most prominent independent small cell backhaul vendor.
...
The event provides an excellent opportunity to meet and reconnect with industry players, both old and new. The emphasis and participation has evolved over the years, but it remains a key focal point to assess the current state of play for the industry.

Here are some things The Mobile Network reported. Full report here:

The day before the Summit started Nokia assembled a few journalists in a meeting room and gave them a portfolio update. Of note in this was the revelation that the company will be shipping tens of thousands, in fact more than 50 thousand, of its Mini Macro cell sites to Sprint. This is on top of another wide scale roll out of the boxes – which are 2x20W sites in a 5 litre box – in China and Japan where the vendor expects to ship another 40,000. There are 3,000 headed to Brazil, as well, to be deployed as an underlay under Ericsson macro cells.
...
One notable aspect of the event was the amount of talk about using small cells in rural, in dense indoor and in other hard to reach areas. Mansoor Hanif spoke of some of the work BT is looking at to enable it to spread coverage to hard to reach areas. There is a real range of work, best summed up in this picture.

Of note is its work with TIP, where it hopes to be able to plug in open base stations as part of its Kuha community-run small cells programme – as per its project on the island of Harris supported by Nokia at the moment. With Lime Microsystems it is delivering a software defined radio base to Open Source, and hopes to attract developers to build applications on top of the Lime SDR platform. Hanif wants to move the cycle for introducing a new feature into a network from months to weeks – but he added that he doesn’t think any operator has the skills to manage that internally – hence the move to Open Source.
...
KDDI’s Fumio Watanabe presented some findings from the operators trials of mobile mmWave systems. The operator’s field trial use 40GHz and 60GHz bands, with a user moving between different bands and being “handed over” between access points. This sort of mobility requires dual interband connectivity and multi-site CoMP to handle the mobility between different sites and bands as a user goes out of line of site of an access point.

It may also require some architecture shifts Watanabe said, including the likes of ICN and MEC.
...
Backhaul provider CCS has a couple of things going on. First, it is involved as the backhaul provider to Telefonica O2’s deployment of outdoor WiFi and cellular small cells in the City of London. Steve Greaves, CEO, said that the company will support 450 small cells and 150 WiFi access points by siting its backhaul nodes at 30 Virgin media fibre points – with each backhaul node supporting 3-5 WiFi access points. The backhaul nodes are providing 1.2Gbps capacities at 24/26/28 GHz bands.

Greaves is also enthused by an upcoming product launch from CCS, as the company enters the 60GHz band with a 10Gbps product. Greaves says that CCS will go beyond products from the likes of Siklu, by modifying the basic WiGig chip that providers currently use, to add tighter carrier grade SynchE 1588, and greater interference control. The product will not be available until early 2018, he added.

Another interesting aspect of the City of London deployment – the concession model between the City of London and Telefonica – means that Telefonica must host other operators’ small cells within the deployment if asked. But these may not be on the same pole as Telefonica’s small cells, given there is a limit of two boxes per pole. From a backhaul perspective – that obviously introduces more complexity – as Telefonica must introduce a V-LAN for each operator, with different QoS.

Virgin Media Business, by the way, has 100,000 cabinets in London alone, and wants to use them to act as potential hosts for small cells, by adding a small pole to the cabinet, said its adviser Paul Coffey. The company is also looking at enabling neutral host model using its street infrastructure. Its wholesale business supplying backhaul to the UK’s operators already runs to £150 million per year, Coffey said.
