The burgeoning interest in on-demand streaming video, together with the proliferation of internet-enabled devices is putting an enormous strain on in-home networks, which can struggle to cope with the growing demands on bandwidth and reliable speeds throughout the home.
Speaking at the Broadband TV event in California this month, HomeGrid Forum president Donna Yasay (pictured), highlighted how these trends are adding to bandwidth congestion and the need to find reliable ways to deliver these vast amounts of traffic. "More and more people are choosing to opt out of traditional broadcast TV in favour of all-IP services," said Yasay, "and they generally no longer have just one entertainment point or internet outlet in the home - it's more likely to be one in every room."
OTT streaming services are predicted to reach over 330 million subscribers globally by 2019, according to a recent Juniper Research study, published in May of this year.
A UK YouGov survey conducted last year reveals that the UK home already has an average of 7.4 internet-enabled devices. The demand is driven by the availability of new devices that provide streaming video, such as connected TVs and streaming media devices, game consoles and set-top boxes, and a plethora of other new gadgets on the market, from wearable technologies to smart devices in the home. Yasay said that this number is likely to continue increasing rapidly as more and more homes install smart metres, security systems, CCTV monitoring and other such systems.
"So what is the downside?" asks Donna Yasay. The answer is, of course: "None, providing your in-home network is up to the task of handling so much bandwidth and dispersing content to all four corners of your home. And of course, if you live in a dense residential environment, such as an apartment block, you need to know that the network can handle the close proximity of other networks, something wireless often struggles with."
Yasay argued that the quality of experience these services require and the bandwidth block that can arise with so much going on in one small space, can only be handled in multi-room, multi-device homes and multi-dwelling units (MDUs) by mixing and matching the wireless and wireline networking to fit individual consumer's or family's needs. "What makes most sense is to take the best of all the networking technologies and combine them," said Yasay. "Wireline technologies of any description, running at Gigabit speeds around the home with G.hn make a robust, reliable backbone, connecting static devices such as TVs, smart meters, desktops, whilst access to the internet from individual mobile devices can "piggyback" with WiiFi onto the network."
The key feature of G.hn is that it is a gigabit networking technology and that it works over any existing wireline medium in the home by simple plug and play. It can send high-speed digital content over any wire and work seamlessly with the wireless networking technologies in the home to build a hybrid system for seamless in-home communications.
