Could Transpositional Modulation be used to solve the “spectrum crunch” problem
Transpositional Modulation (TM) permits a single carrier wave to simultaneously transmit two or more signals, unlike other modulation methods. It does this without destroying the integrity of the individual bit streams.
TM Technologies (TMT) is a wireless technology company offering dramatic data throughput increases for existing wireless and wired networks, using TM.
TMT’s In Band Full Duplex (IBFD) is a MIMO-compatible antenna and software technology providing signal interference cancellation via its Adaptive-Array Antenna which allows simultaneous transmit and Receive = Doubling Data Rates. TM-IBFD development has shown a combined 120 db noise reduction in two-way communications, which provides up to a 100% gain in wireless data transport efficiency.
TMT believes that the use of its patented methods can prevent or delay the onset of a wireless “bandwidth crunch” and focuses on developing products for a range of applications. These products will use core technology to provide solutions and create value for customers, the economy, and the global wireless infrastructure. The company says that the TM-IBFD is backwards compatible and complimentary with existing beam forming or beam shaping installations.

Using the latest Xilinx RFSoC devices, TMT has produced a Software Defined Radio (SDR) format with OFDM as primary modulation with multiple TM channel overlays. This is applicable to nearly any access or backhaul radio device with adequate head-space and operating within the 3GPP Rel 16 specifications.
Industry analyst Jeff Kagan wrote: “Spectrum shortage remains a problem that is not going to solve itself. That’s why new solutions like this are necessary….In the case of solving this spectrum crisis, there are two different groups to focus on. One, is the wireless carriers. Two, are wireless network builders. Either, the customer, which is the wireless network needs to demand this from their network builders. Or the network builders need to embrace this as a competitive advantage and as a solution to their customers.”
