In the future, network communication will not be limited to 3G broadband, wireless network (WiFi) and satellite communication. The "white space" known as "super WiFi" is expected to make up for the limitations of the existing technology, even in dense forests Golf courses or boats away from the coastline can also enjoy high-speed Internet.
TV white space refers to the radio spectrum that is not used in the TV broadcast band. With the proliferation of mobile devices such as smartphones and tablets, wireless network traffic has become more and more crowded, radio frequency spectrum has become a rare commodity, and the use of off-the-shelf TV white space has become a relief for "band tension" Possible solutions.
"Super WiFi", which has a lower frequency than ordinary WiFi, not only has a wider coverage, but also has stronger penetration, which can make up for the shortcomings of existing wireless networks and broadband networks, including penetration of buildings, trees and bad weather.
The Singapore Island Country Club used these advantages of "Super WiFi" in the pilot program to strengthen the wireless network in the club.
Facing the jungle, hills, reflective water surface of the reservoir and the unique terrain environment with frequent rain showers, the club ’s previous attempts at broadband wireless solutions, including some extreme methods such as installing antennas on balloons, ended in failure.
After the adoption of "Super WiFi", the club has achieved initial success, and in the future it can be further extended to use network technology to manage water and energy, eliminate wireless blind spots between existing buildings, and provide WiFi for four 18-hole golf courses service.
Xinghe also used the "Super WiFi" signal to send farther features to launch a test plan. Its equipment installed in Changi can provide network services for ships 10 kilometers away from the shore.
Liu Wangfa, manager of Xinghe Innovation and Development Department, said that currently the crew mainly uses 3G broadband and satellite communications, but the signal of 3G broadband will weaken after two to three kilometers offshore, while satellite communications are expensive, so "Super WiFi" provides Compromise solution.
In addition, "Super WiFi" can also reduce network costs and promote the application of network technology in other areas.
One example is the pilot program of the Information and Communication Research Institute in the university town of the National University of Singapore. Through the Advanced Metering Infrastucture installed in the dormitory, schools and students can effectively manage electricity usage.
The team launched a series of test plans
The above three examples are all a series of test plans announced by the Singapore White Space Pilot Group (SWSPG) established in April this year. Microsoft Singapore, ICT Research Institute and Xinghe are the founding members of the group.
During this one-year plan, the team will provide data and user feedback to the Information and Communications Development Authority (IDA) so that the authorities and other regulatory agencies can establish a corresponding regulatory framework.
At present, the United States Federal Communications Commission (FCC) has approved the setting up of "Super WiFi" in Wilmington, North Carolina, to facilitate residents to access the Internet in public places such as parks.
However, "Super WiFi" is still in its infancy. Because the frequency of this new technology is different from ordinary WiFi, special equipment is required. To use "Super WiFi" on computers, mobile phones and other equipment like WiFi, manufacturers must It will take a while to produce chipsets that can run on both systems.
