THE CHALLENGE FOR SPECTRAL EFFICIENCY
AND HOW LEXTRUM SOLVES IT
TDD AND FDD LIMITATIONS
FDD, and later TDD, technologies have been the foundation of 2G, 3G, and most recently 4G networks. With the advent of 5G networks, and the continually growing need for both spectrum efficiency and increased throughput, these traditional technologies have reached their limits.
THE LEXTRUM FD SOLUTION
The Lextrum FD solution marries the spectral efficiency of TDD with the throughput advantage of FDD, making it the obvious choice for meeting the rigorous requirements of today’s developing 5G networks. The flexibility of the Lextrum FD solution means it can support legacy 4G protocols, and new 5G protocols, allowing a seamless transition from one generation to another, as networks evolve.
THE MARKET REQUIRES TRANSCEIVER INNOVATION
THE NEED TO MAXIMIZE SPECTRAL EFFICIENCY WILL BE EXPOSED BY...

GROWTH
occurs every year as devices innovate and increased media is transmitted.
SPECTRAL
EFFICIENCY
is essential to meet bandwidth demand when channels are limited.
WIRELESS
TRAFFIC
increases every year by user and the numbers of devices on networks
DENSE
ENVIRONMENTS
call for technology that improves spectral efficiency, without sacrificing throughput or performance
THE PROMISE
OF 5G
requires technologies that allow network operators to take advantage of all 5G will have to offer.
SPECTRAL EFFICIENT TECHNOLOGIES
-
Supports simultaneous transmit and receive in a single channel
-
Maximum spectral efficiency with 2x throughput increase
-
Merges best of FDD/capacity and TDD/spectral efficiency
-
Self-interference cancellation via passive suppression and active RF and digital cancellation
-
Achieves +120 dB aggregate self-interference cancellation
-
Reduces multi-path self-interference to below noise floor
Use of beam steering antennas controlled by smart antenna heuristics achieves spatial filtering of self-interference multi path
