"Smart grid features a two-way flow of power and information, which is built as a highly automatic and widely used energy exchange network. To achieve real-time information exchange and instant demand-supply balance on equipment, smart grid makes full use of distributed computing and communication networks." "Smart grid infrastructure integrates the energy and communication systems. Where there is a smart grid, there is a reliable two-way communication network to support power services."

High Valued by Zhuhai Power Supply Bureau

“This is the first application of TD-LTE technology in the

power industry.

It has helped us to solve the problems of difficulty in

constructing optical cable, poor reliability and security of

using public network and the complicate maintenance of

old network.

It has enabled us to have multiple services of high

speed data, VOIP and video surveillance under NLOS

condition and different scenarios which has improved

the overall performance and efficiency of grid network

and improved the online rate of power distribution

terminal.”

Challenges of Zhuhai Power Supply Bureau

• Difficult optical network deployment because of

complex power distribution grid structure, grid

coverage areas, and millions of power terminals

• Reliability and security of public network is poor

and is prohibited from carrying remote control

service of distribution automation.

• WiMAX industry is shrinking and cannot guarantee

long term availability

• PLC,PON and Ethernet has limitation for

distribution automation due to cable mode.
