World : Huawei promotes 4.5G-based wireless for smart grid

Chinese technology giant Huawei released for electric utilities its 4.5G-based, 5G-oriented eLTE Discrete Spectrum Aggregation (eLTE-DSA) solution at the CEBIT conference in Hannover, Germany, the firm said Friday. It gives energy firms ubiquitous all-service "internet of energy" (IOE) through fast wireless access, low latency, greater connectivity, and reduced power consumption, the firm said.

"Huawei has proposed the vision of 'Leading New ICT, Bits Drive Watts' in the electric industry," said Jerry Ji, president of the Energy Industry of Huawei Enterprise Business Group, reportedly in remarks at the event. "Huawei is committed to bringing digital technologies to every electric power company."

The firm debuted many smart grid innovations at the event, and called eLTE-DSA "a killer technology" to optimize power distribution and consumption. As energy consumption increases globally and the industry moves toward renewable energy, the implementation of the IOE will become an important way to advance the energy revolution, driving clean energy and sustainable energy development, the firm said.

IOT is the foundation for the IOE, and with clear advantages in security, reliability, ubiquity, economy, and flexibility, private wireless networks have proven to be the ideal access solutions to develop the IOE, it added.

Spectrum is a critical component for building private wireless networks and poses challenges when deploying these networks. Traditional narrowband solutions based on VHF (30 MHz to 300 MHz) and UHF (300 MHz to 3000 MHz) bands are flawed, with low data rates, long latency and small capacity – and are thus unable to meet the demand for sustaining IOE growth, the firm said.

Huawei designed eLTE-DSA to overcome the obstacles of traditional narrowband solutions and support IOE developments through leading advantages in wireless communications developed over the years, it added. By aggregating discrete narrowband resources, this solution achieves access with an end-to-end delay as low as 20 MS (milliseconds) and a huge capacity of up to 4,000 users in a single cell.

The transmission rates reach KB/S (kilobits/second) to MB/s (megabits/second) and the module power consumption is as low as 0.15W, the firm said. This solution noticeably improves spectrum efficiency, capacity, and performance of the networks, enabling the energy industry to move seamlessly towards 5G-oriented IOE, it added.  

"Going wireless will provide the foundation for the internet of energy," Huawei Enterprise Wireless Business President Eric Sun in prepared remarks. "4.5G technology will enable the internet of things, and 5G will accelerate the connection of people and things.

"With leading technological advantages in 4.5G and 5G, Huawei has successfully developed the 4.5G-based, 5G-oriented eLTE-DSA solution."
