Yuqing Niu, Chair of HomeGrid Forum MWG Asia gave a speech in SMAhome International Conference and Exhibition 2017 to present the latest technology innovations and development. She indicated that G.hn technology can enhance and stabilize the indoors Wi-Fi coverage by existing wires. Here is the summary of her speech.
The most crucial infrastructure for smart home systems are home networking connectivity, described as the “backbone” of smart home. No matter it’s wired or wireless communicated, the connection has to provide a reliable accessibility for users in anywhere, and in every single corner of their homes.
Traditionally, people used to apply networks in two ways, either a home gateway plus an Ethernet cable, or a gateway with a Wi-Fi network. But Ethernet requires every device at least a corresponding socket and switch, and the using area is limited; Wi-Fi connection relies on the stability and might be inactive while the network is unavailable. “Wi-Fi coverage is always an issue at home,” said Niu.
Carrying Out the Networking Solution for Future
As a result, G.hn technology was carried out. Matching the ITU-T Wireline Communication Standards, G.hn technology is able to turn all existing physical wires at home into Ethernet cables, including power line, telephone wire and coaxial cable, so every rooms are well connected to the gateway and have wireless connection inside the rooms. “G.hn technology is going to turn those physical media into Ethernet cable,” said Niu.
Apart from the ability to operate on multiple kinds of legacy wires, G.hn technology can keep a stable connection backed up by 128-bit AES encryption.
HomeGrid Forum started applying the G.hn technology in China. With over 200 million homeowners today, the usage for wireless network is tremendous. How to transmit stable contents and internet services has become a problem. In March 2017, HomeGrid Forum cooperated with China Telecom using G.hn technology through coaxial cables to support 4K IPTV. Also, the telephone wire is successfully used to support home connectivity for video service. (More: New Member in HomeGrid Forum Raises Service Providers’ Attention in China)
G.hn technology is also applied for surveillance IP camera networks in smart cities. Instead of a high expense on replacing the coaxial cables into Ethernet cables, G.hn technology reuses the old coaxial cables and supports many IP cameras on one shared cable.
“With all those media at home, you can set up a very strong home networking infrastructure. This is the key idea and the value in the future for smart home,” said Niu.
