Ericsson and Deutsche Telekom say the results of a wi-fi backhaul trial show the technological innovation can give a genuine option to fibre for 5G networks in the long run.
The two firms attained speeds of 40Gbps more than a distance of one.four kilometres at Deutsche Telekom’s services centre in Athens, Greece. This is four instances the existing 10Gbps limitations of millimetre wave (mmWave backhaul).
But just as crucial is latency. The full spherical-trip latency was fewer than one hundred microseconds – an critical milestone for 5G networks that assure ultra-minimal latency properties.
5G wi-fi backhaul
The use of wi-fi backhaul could change the economics of 5G network deployment and assistance operators bring protection to spots exactly where there is an absence of suited set backhaul. Operators have often voiced their requires for extra fibre networks to support rollout and have supported any transfer to ease laws.
“Microwave proceeds to be a important technological innovation for mobile transport by supporting the potential and latency prerequisites of 4G and long run 5G networks,” explained Per Narvinger, Head of Product Location Networks at Ericsson. “Our joint innovation challenge exhibits that bigger potential microwave backhaul will be an crucial enabler of substantial-quality mobile broadband solutions when 5G turns into a industrial fact.”
“A substantial-overall performance transport connection will be important to support substantial information throughput and improved consumer knowledge in future-technology networks,” included Alex Jinsung Choi head of Method & Engineering Innovation at Deutsche Telekom.
“While fibre is an crucial portion of our portfolio, it is not the only alternative for backhaul. Together with our partners, we have demonstrated fibre-like overall performance is also possible with wi-fi backhauling/X-Haul alternatives. This provides an crucial extension of our portfolio of substantial-potential, substantial-overall performance transport options for the 5G era.”
Although Ericsson will be buoyed by the results of its newest exams, investors will be anxious at a six.one billion SEK (£540m) charge to its accounts just after failing to achieve the desired results from tis Enterprise Guidance System (BSS) division.
