OTFS is the industry’s most spectrally efficient airlink

Unprecedented Capacity, Performance and Coverage

Demand for broadband connectivity continues to grow at a meteoric pace. The advent of 4K TV, multiple high resolution display devices in the home and streaming technology is creating an insatiable demand for bandwidth that network operators are unable to meet.


Cohere Technologies has developed a 5G Cloud RAN solution that is based on the company’s groundbreaking Orthogonal Time Frequency and Space (OTFS™) technology.

The solution is a single platform for a wide variety of applications from Fixed Wireless Access, Mobile Broadband to Smart Homes and Cities to Industrial Internet of Things.

Network Operator Challenges




Demand for 1000x increase in capacity

Networks require a 1000x increase in capacity to meet the growing demand for data. Existing alternatives are incapable of meeting this demand.





Delivering fiber-like service everywhere

Operators want to extend the coverage of existing broadband networks cost effectively. Existing alternatives are incapable of meeting this demand





Enabling profitable broadband service

Cost to deliver bandwidth must compete with fiber. Fiber is too expensive to deploy ($1000-5000 per household passed).

OTFS performance proven in the field with OTFS for fixed wireless access

Cohere’s OTFS as an FWA solution is a flexible and scalable solution that delivers broadband access to rural, urban and suburban environments. OTFS is an entirely new multi-dimensional modulation that overcomes the inherent issues of wireless transmission far more effectively than the current modulations (e.g., OFDM, and CDMA) to dramatically increase bandwidth and coverage. OTFS builds a stable, deterministic and non-fading representation of a wireless channel to allow the receiver to coherently reassemble primary and multipath reflections of a transmitted signal. This maximizes the capacity of the channel to near Shannon’s capacity level. In addition, OTFS sustains the performance despite changes in channel conditions due to fading and Doppler. This ensures a guaranteed high capacity link under any condition.

Last year Cohere demonstrated a significant improvement in spectral efficiency for OTFS as compared to today’s available solutions. The fixed wireless access trial was conducted with Telefonica in Madrid, Spain along with 5TONIC Labs, and measured spectral efficiency of 57 b/s/Hz across 14 layers. With OTFS backwards compatibility, Cohere and partners help deliver on the promise of 5G with seamless 4G to 6G coexistence.
