RTT - provide RF engineering and radio technology support to the cellular radio industry, broadcasting, two way radio and satellite industry.

We provide RF consultancy support to operators and vendors, helping them to make faster and better decisions on radio frequency (RF) technology, engineering and infrastructure investment with a specific focus on 5G and satellite technologies.


5G Research from RTT

To be economically sustainable, 5G will need to go faster and further at lower cost using less power than present and future 4G LTE systems.

In terms of the physical layer, considerable research is being dedicated to massive MIMO systems implemented in TDD spectrum.

However it is hard to see how this approach can deliver significant  benefit over present and future Wi-Fi technologies.

5G will need to be capable of supporting high data rate high mobility users in wide area large radius cells with a dynamic range of the order of 100dB.

This can only be done economically by exploiting fractional beam width antennas deployed into FDD spectrum with channel bandwidth ratios that are efficient both in terms of RF efficiency and multiplexing gain.

By default this requires 5G to be deployed into the centimetre band (channel bandwidths of 250 MHz) and millimetre bands (channel bandwidths of 500 MHz and 1 GHz).

This means that it is essential to coordinate 5G technical and commercial planning with existing and future satellite industry business models, satellite spectum and (FDD) band plans, satellite space assets, satellite network topologies and the satellite industry supply chain.


New syndicated research study from RTT, Policy Tracker and The Mobile World - coordinated in association with Collaborata.

'A timely and critical investigation into 5G and satellite industry supply chain economics and spectral and space asset value'

The study provides a definitive economic and technical analysis of the 5G and satellite industry supply chain with an associated forward forecast of future asset and business value and relative competitive positioning.

RTT Technology Topics

RTT Technology Topics reflect areas of research that we are presently working on.
We aim to introduce new terminology and new ideas to help inform present and future
technology, engineering, market and business decisions.

This  month’s (January 2017) technology topic GAFASAT analyses how technology innovation is reducing capex and opex in the satellite industry and increasing capex and opex in the mobile broadband industry and the associated implications for the 5G and satellite industry supply chain and other stakeholders.
 
On the RTT website there are over 200 topics ARCHIVED starting from August 1998. The archive provides a free valuable resource for researchers in the industry wishing to use past case study experience to validate technology, engineering, market and business decisions.
