Optical fibre alternative proves to be “six times better” than competing technologies, say developers.

5TONIC Labs, Telefónica, and Cohere Technologies report that they have cooperated in “successful trials” to test Cohere Technologies’ latest 5G turboConnect Fixed Wireless Access solution.

The solution uses Cohere’s patented OTFS modulation to deliver broadband access to urban, suburban, and rural environments. Based on the results of these tests, Cohere’s spectral efficiency was proven to be nearly six times better than other solutions, providing unprecedented coverage and capacity at a fraction of the cost of fibre or alternative technologies.

The tests, conducted over three days at 5TONIC Labs and Telefónica headquarters, were designed to demonstrate high spectral efficiency via joint equalization and linear scaling.

In the tests, Cohere achieved aggregated throughput of 300 Mbps in 10 MHz, with a measured spectral efficiency of 57 b/s/Hz across 14 layers in a 90 degree sector.

The partners say that this “clearly demonstrating the industry-leading capabilities of Cohere’s 5G turboConnect access platform and its ability to deliver impressive performance under real world conditions.”

Linear scaling
The tests also showed 5G turboConnect enables capacity to scale linearly with antenna layers and channel bandwidth, making it applicable to a variety of fixed and mobile broadband use cases.

“The objectives of the tests were to show the spectral efficiency based on measured throughput, and evaluate coverage, the role of interference, peak data rates, linear scaling with MIMO order, real time processing, and the ability to scale. These are key performance indicators required for a successful deployment of Fixed Wireless Access service,” said Arturo Azcorra, vice-chairman, 5TONIC.

“We are very happy with the results obtained, that clearly improve on those obtained with other technological solutions. We look forward to continue cooperating with Cohere in the testing of its OTFS solutions, both for FWA applications as well as for other use cases, such as ultra-reliable communications and connections with high-speed vehicles.”

Introduced at Mobile World Congress 2018, Cohere’s 5G turboConnect leverages standard architecture and components to implement a state of the art software-based cloud RAN solution. This reduces total cost of ownership and enables the operator to quickly deploy services.

10X capacity per cell
The new Massive MU-MIMO Antenna technology produces 10X capacity of LTE per cell, with 100% coverage and 100% spectrum re-use. It is interference resilient and provides uniform SLA across cell. An entirely new multi-dimensional modulation, OTFS overcomes the inherent issues of wireless transmission far more effectively than the current modulations to significantly increase bandwidth and coverage.

The tests conducted by 5TONIC were designed to assess the suitability of OTFS based radio equipment for supporting fixed wireless access, a potential 5G use case that Telefónica and other operators are actively exploring. 5TONIC administered tests over three days where several links with different lengths and propagation conditions were established at two different locations: the 5TONIC lab, and Telefónica headquarters at Distrito Telefónica.

“The true star of these tests is OTFS, proving once again the technology delivers a guaranteed high capacity link under any conditions,” said Shlomo Rakib, Chief Executive Officer at Cohere Technologies.

“Working with Telefónica and our 5TONIC partners, we were again able to demonstrate in a real-world scenario how OTFS is an ideal candidate for 5G and beyond, achieving spectral efficiency nearly six times better than any other competing solutions. With this milestone, Cohere continues its successful track record of demonstrations and trials, completed in cooperation with a broad range of operators around the world,” he added.
