A back-to-school treat awaits students, faculty and staff at a Sichuan province medical college this fall: strong, clear wireless Internet service from what is due to become the largest campus Wi-Fi network in China, installed by a California wireless technology company.

Ruckus Wireless Inc of Sunnyvale, California, has teamed up with China Telecom, the State-owned telecommunications giant, to complete phase one of the state-of-the-art system at Luzhou Medical College in western China.

Covering 550,000 square feet of classrooms and offices and 338,000 square feet of dormitory buildings on two major campuses, the network provides "reliable, high-performance Internet access" to more than 15,000 faculty and students, Ruckus said.

Liu Yuqing, the college's network center director, said the upgrade - which wasn't announced until a nine-month monitoring period confirmed its success - has ended the frequent dropped signals and unstable connections that had baffled the college's technicians.

"We did not receive any complaints. We're now free to focus on other important tasks, like educating our students," Yuqing said.

Chris Yip, Ruckus' Asia-Pacific marketing director, told China Daily the installation represents a triumph over the technical hurdles involved in delivering Internet service to thousands of faculty and students who are increasingly using smartphones, tablets and other mobile devices.

More than 1.2 billion people are now connected to the mobile web via smartphones or tablets, and China is the world's largest smartphone market with more than 400 million mobile Internet users, according to Analysys International.

Mobile devices "have become increasingly popular with students in the last two years, highlighting the growing bring-your-own device trend in educational institutions around the world", Ruckus said.

However, when a large number of mobile devices are operating simultaneously in the same area, traditional Wi-Fi systems struggle with a lack of capacity, causing users to suffer losses of signal, or "drop-outs".

Conventional systems "simply can't accommodate" the challenges posed by high user density, Yip said.

"Mobile devices are different from desktop PCs and laptops as users carry them on the go, so the orientation of the built-in antenna of the mobile device changes constantly, which will in turn affect the Wi-Fi receiving capabilities," he said.

"User density" at Luzhou has surged "two to three times" in recent years as mobile device use soars, Yip said. Connectivity problems are particularly acute in dormitories in China because eight to 10 students on average may share a unit - more than at a typical US college dormitory, he said.

And with a greater number of indoor areas on Chinese campuses than in the US, "there are more walls, windows and doors for Wi-Fi signals to penetrate to reach the mobile device," Yip said.

Luzhou Medical, which is based in Luzhou, Sichuan, worked with China Telecom to complete the project's first phase last September, mainly covering dorms, offices and teaching buildings. Owing to phase one's success, the college plans to initiate phase two, which would extend the system campus-wide, Ruckus said. When completed, the system will be the largest of its kind in China, the company said.
