Qualcomm's new hardware will help mobile 5G get off the ground
If mobile 5G is going to become more than a nice idea, it needs the thorough coverage you expect today -- and that means putting it in the small cell sites that boost coverage in busy areas. And Qualcomm might just play a pivotal role in making that happen. The company is launching the first 5G New Radio platform (the catchily named FSM100xx) that brings gigabit data speeds to small cells. It can handle 5G on both regular frequencies and millimeter wave, and it promises to be helpful both indoors, where 5G's high frequencies don't always penetrate, as well as the great outdoors.
Verizon will speed up San Francisco data by installing 'small cells'
Some carriers use "small cells" to boost their coverage, because these relatively tiny transmitters are 1.) a lot cheaper, and 2.) more inconspicuous than their traditional counterparts. Verizon is one of those carriers -- in fact, it's planning to install 400 small cells in certain high-traffic areas in San Francisco starting this second quarter. These devices (designed by Ericsson) will be integrated into street lamps and will generally blend into the surroundings within SF's Financial District, SOMA, Market Street and North Beach neighborhoods. The cells do have a limitation, though: each one can only cover an area that has a 250 to 500-foot radius. That's why for this particular rollout, Verizon plans to lay down the structure for a dense network made up of numerous small cells covering some parts of the city only.
Virgin's small-cell networks to improve 4G coverage in the UK's biggest cities
The UK government has been pretty vocal about carriers needing to improve network coverage in rural areas, but that's not to say everything's hunky-dory in some of the UK's biggest cities. That's why Virgin Media Business -- the part of Branson's empire that deals with broadband infrastructure and the like -- is combining its fibre network with wireless expert Arqiva's knowhow to improve 4G coverage in cities including London, Birmingham, Manchester, Leeds, Bradford and Southampton. To do this, the pair will install small-cell technology (which, incidentally, EE is using to bring coverage to underserved rural regions) in "street assets" such as lampposts and CCTV cameras. These mini-masts will increase network capacity and improve 4G coverage in areas where buildings can get in the way of the signal. When the small-cell systems are up and running, the idea is carriers will pay Virgin and Arqiva to access them. That should be an easy sell, however, since they can immediately improve 4G services for their customers, no new infrastructure investment required.
Qualcomm aims to solve the coming mobile data crunch with small cell base stations
Qualcomm's been doing very well lately, and most of those chips it builds are for mobile devices that demand a lot of data to serve their owners' needs -- and as more and more folks jump on the smartphone bandwagon, the demand for data will continue to grow exponentially. Today at Qualcomm's What's Next in Mobile event in Santa Clara, California, the company told us more about its plan to help build a network that'll be able to serve up the data all its SoC's need. The goal is to give us 1000 times the capacity of what we currently have. One of the key parts, as Qualcomm sees it, is small cell base stations in homes, offices and retail spaces working in tandem with the large cell towers that currently adorn so many roofs and mountain tops -- the same thing ex-FCC head honcho Julian Genachowski talked about last year. You see, macrocells (read: towers) can blanket wide areas in signal, but they struggle to penetrate the innards of buildings, which is where small cells come in handy. For those who aren't familiar, small cell base stations like femtocells and picocells have been around for years, helping to boost cell signal in small areas by hooking into a local wired network. Until now, these small cells have served as a small-scale supplement to macro networks, but Qualcomm CTO Matt Grob sees them comprising a much bigger chunk of the network of the future. According to him, there are a few issues with using them in an expanded role, however.
Visualized: AT&T's network-boosting Small Cell
WiFi used to be the only somewhat reliable way for a carrier to plug up holes in its network coverage. It's a tactic AT&T's used to great effect in many metropolitan areas where it offers wireless service. But short of acquiring more spectrum -- a costly and time-consuming process littered with legal roadblocks -- the operator's been exploring an alternative solution: small cells. Testing for these stopgap signal boosters (pictured above) has already been underway since late 2012, with a trial case study in Crystal Lake Park, MO that proved outdoor reception could improve by almost 100-percent. And that test site is just the start of a greater small cell rollout that should place over 40,000 of these units throughout AT&T's nationwide footprint by 2015. So if you're tethered to the operator's network and sick of spotty coverage, help is most definitely on the way.
AT&T small cell site pilot due between late 2012, 2013
AT&T has been hinting for a while that it's getting closer to implementing small cell sites in its network, and at CTIA Wireless 2012 gave a stronger clue as to when and how the mini network hubs will operate. Executive technology VP John Donovan clarified to Reuters that a pilot is expected to start late this year and should run into 2013. If all runs smoothly, the below-tower-sized sites will be clipping on to lamp posts and other parts of the urban landscape to strengthen coverage in places where wide-area WiFi alone won't do. While Donovan didn't venture deep into the infrastructure at the trade show, Cisco had previously said that AT&T would be using sites incorporating 2G, 3G, 4G and WiFi when the provider did start experimenting with small cells. If so, there's a chance subscribers could get AT&T WiFi without having to turn to an airport, landmark or coffee shop.
