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 be done at centimetre and millimetre wavelengths using fractional beam width antennas but could potentially also be achieved in longer wavelength spectrum including existing LTE bands below 3 GHz including sub 1 GHz, an option which could potentially deliver improved EBITDA for the mobile operator community.
Wherever 5G is deployed it will be essential to coordinate 5G technical and commercial planning with existing and future satellite LEO/MEO and GSO business models, satellite spectrum, satellite waveforms, FDD band plans and space assets.

New Book Project

RTT, The Mobile World and Policy Tracker are working on a new book project on 5G and Satellite Spectrum and Standards and related regulatory and competition policy issues prior to WRC 2019. The book will be published by Artech House in June this year.

If you are interested in knowing more about this project or are developing products and services that you feel should be included or a regulatory and advocacy position that you feel should be reflected then please email us for more information.

5G and Satellite Workshop in the Caribbean - 23-25 April 2018

We are pleased to announce that our next 5G and Satellite workshop, presented in association with Niche Markets Asia will be held in the Caribbean this April. For details, including the early bird registration booking offer, follow this link.

5G spectrum and standards bookLearn about the real life performance trade-offs between the metre band (300 MHz to 3 GHZ), centimetre band (3 GHz to 30 GHz) and millimetre band (30 to 300 GHz) by ordering Geoff’s new book 5G Spectrum and Standards

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.

In this month’s (January 2018) Technology Topic, STEAM SHIPS AND SPACE SHIPS - a new golden age of connectivity? We look at how physical scale improved the performance of steam ships, and how the same effect is delivering efficiency gain in high count satellite constellations.

On the RTT website there are over 230 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.
