Draft standard would alleviate rebuffering on mobile devices

HQME's P2200 standard, now under IEEE review, proposes "intelligent" content caching

A newly formed industry group has proposed a standard that could significantly boost the upload speeds of video content to mobile devices.

The High Quality Mobile Experience (HQME) Steering Committee said their P2200 draft standard proposes using local storage and intelligent content caching to relieve network congestion and thus accelerate data delivery to mobile devices.

HQME's P2200 draft has been accepted by the Institute of Electrical and Electronics Engineers (IEEE), and is now under review there.

"This issue affects all members of the mobile ecosystem, including content owners, network operators, device manufacturers, memory providers and app developers," said Flint Pulskamp, IDC's research director for wireless and wired communications semiconductors, in a statement. "The proposed solution requires an industry-wide approach so that it is both effective and sustainable."

The HQME Steering Committee includes hardware manufacturers, service providers and entertainment companies, such as SanDisk, SoftBank Mobile, Sony Pictures Entertainment and Orange.

According to Cisco, consumer demand for mobile content is set to outpace the needed spending and innovation in network capacity for years to come.

Bandwidth constraints today cause users to stare at loading animations as a video pauses to rebuffer over and over again.

Overall mobile data traffic is expected to grow at an annual rate of 92% between 2010 and 2015, which would keep the bandwidth constraints in place. The projected growth of 6.3 exabytes per month by 2015 represents a 26-fold increase over 2010, according to Cisco.

The rebuffering problem is expected to worsen over time as content size grows while bandwidth continues to be constrained, according to the HQME Committee.

The proposed IEEE P2200 standard would use memory on the mobile device as the last node on the network, which calls for compliant applications to download content when the mobile device is connected to AC power and Wi-Fi instead of during peak hours the next day.

Essentially, by utilizing the device's onboard memory it would preemptively download content to the device's local storage, allowing users to access the content they want while circumventing the bottlenecks associated with mobile network congestion during peak hours.

Susan Kevorkian, research director of IDC's mobile connected device service, said in a statement that HQME's intent is to align key mobile content delivery players in an effort to minimize the inconveniences associated with acquiring content over capacity-constrained mobile networks.

"Intelligently coordinating content delivery in advance to local device storage lets consumers enjoy their video, games, periodicals, books and music when they're ready, and may help mobile operators and service providers to reduce churn by improving the perceived quality of the experience," Kevorkian said.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
