Radisys marry DAS with Small Cells

Renuka-Bhalerao-Radisys-150DAS (Distributed Antenna Systems) are usually positioned as the very expensive competitor against the up-and-coming, low cost small cell products. Radisys have been at the forefront of small cell development, providing software solutions for many ODMs and OEM players , so it's something of a surprise to see them talking about DAS.

We asked their senior line product manager, Renuka Bhalerao, for more detail.

DAS Congress Europe event report

DAS Small Cells Congress EuropeThis popular US event came to Europe for the first time and drew a larger than expected crowd. Although the full event title includes Small Cells, I think it's fair to say the content and exhibits were very heavily DAS focussed. It provided a good perspective of how DAS products are evolving, but I felt was still somewhat US market oriented and lacked a deeper European operator perspective. Frankly, I'd hoped for a bit more lively debate with the small cell community too. I attended only the first day of this two-day event, which seemed oversubscribed and more popular than anticipated.

Alan Law, New Small Cell Forum Chairman, sets out expanded scope of activity

Alan-Law-SCF-Chairman-150The Small Cell Forum has just elected its third Chairman in seven years, with Alan Law moving up from Vice-Chair. He's been a long time Small Cell proponent, active Forum Member and focal point for Small Cells within Vodafone Group. Alan reaffirms the Forum's primary role, reveals how the Forum's Virtualisation workstream is leading towards a much wider scope, and answers some challenging questions about the difficult choices facing the mobile industry.

LTE Advanced increases timing and synchronisation requirements for Small Cells

clocksHigh spectral efficiency and smooth performance of mobile networks is aided by accurate and reliable timing synchronisation. This is even more important in an LTE HetNet environment which co-ordinates transmissions across macro, micro and small cell layers.

Leading oscillator vendor Rakon has published a white paper discussing this topic and we've extracted the salient points below.

Broadband World Forum 2014 show report

bbwf logoThis was quite a wide-ranging event, trying to cover all aspects of wireline and wireless connectivity with multiple specialist streams including one for mobile backhaul. There was relatively little Small Cell activity overall. I chaired part of the Mobile stream and participated in two panel sessions, which included several very good presentations. Retiring European Commission VP Neelie Kroes gave a well attended speech reflecting on some of her difficulties as EU Digital Commissioner, contrasting strongly with FCC Tom Wheeler's positive speech at CTIA last month.

Rajesh Mishra, co-founder Parallel Wireless, imagines a different future for HetNet RANs

Rajesh Mishra Parallel Wireless 150Rajesh believes that technology disruption from low cost silicon, COTS hardware and smarter software will drive the industry towards a different RAN architecture. He explains why his startup venture Parallel Wireless have adopted this alternative approach, pointing out the advantages of an LTE gateway and mesh interconnected small cells.

Distribution of people in sparsely populated areas favours Small Cell solutions

VillageAt this year's CW Future of Wireless conference, Simon Saunders of Real Wireless characterised the cost of servicing remote and rural areas. This is quite topical, since the Small Cell Forum is currently developing its next release on that subject. It seems that people who live in rural regions aren't quite as anti-social or equally dispersed as we city-dwellers might think. They often live in groups within villages or hamlets, providing adequate return on investment for a low cost deployment. This favours infill using pockets of coverage rather than increasing capacity through a heavy-duty macrocell approach.

Designing Stadium Wi-Fi for successful offload

amex-stadiumPeople often tell me that you couldn't use cellular small cells to cover a sports stadium – other more expensive cellular systems are required. At the same time, we've seen Wi-Fi successfully deployed in these same stadium environments. ATT carried 1.5TBytes of data over Wi-FI at the SuperBowl, three times that of their cellular traffic. Sami Susiaho explained at BBWF how The Cloud (a UK Wi-Fi network) designed and deployed a Wi-Fi solution at Brighton and Hove Albion stadium during summer 2014.

Every telegraph pole across UK now a potential outdoor small cell site

Telegraph-PoleOpenreach, the UK national wireline infrastructure provider, launched a new service this month called MiiS. It offers to sub-let any of its telegraph poles for use as a small cellsite, providing a small street cabinet, backhaul, mains power and even a pole-top antenna. This promises to make it easier for network operators to target and deploy large numbers of smaller outdoor sites, especially in suburban areas, accelerating take-up.
