RTT - provide RF and optical engineering support to the 5G and satellite industry..

We provide RF and optical engineering consultancy to operators and vendors, helping them to make faster and better decisions on radio frequency (RF) and optical (fibre) and free space (FSO) infrastructure investment and help 5G and satellite supply chains identify emerging risks and opportunities.

The auction of 100 MHz of C band spectrum in the 3.5 GHz band for $80 billion dollars in the US earlier this year has helped to drive global investment in a new wave of high capacity terrestrial cellular networks. In the 5G community we think of these as radio systems but in practice these networks are dependent on the efficient integration of RF and optical transport at optical C band (191 THz to 195 THz).

In parallel for $8 billion dollars a satellite operator can have a LEO constellation with several thousand satellites covering all latitudes and longitudes with multiple payloads including GNSS, multi spectral sub metre imaging and global Wi-Fi. Increasingly these networks are deploying inter satellite and inter constellation optical switching and optical uplinks and downlinks to provide cost effective power efficient bandwidth and added value to terrestrial networks.

These are not new technologies. The industry has been deploying terrestrial fibre now for fifty years and RF over fibre for thirty years and today’s high count LEO constellations are a second iteration of Ku and Ka band networks planned thirty years ago (Skybridge and Teledesic).

Over the past fifty years, losses per kilometre in terrestrial fibre have reduced from 20 dB per kilometre to 0.2 dB per kilometre. In space, 60,000 kilometre links are being deployed at low power and low cost transforming the delivery economics of long distance broadband backhaul. Ever higher levels of coherent modulation make these links ever more efficient.

RTT bridges the gap between RF and optical terrestrial and space engineering and provides guidance on how the integration of RF and optical technology can change the economics of present and future terrestrial and non-terrestrial networks.

If you are interested in writing a book for Artech House or have research work you would like included in future 5G and 6G and satellite titles then email geoff@rttonline.com who can put you in touch with the Artech commissioning team.

Our next LEO, MEO and GSO and 5G NTN workshop presented in association with the Continuing Education Institute will be held in Munich from 25th to 29th November 2024



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 is the last Technology Topic until October 2024.
I am writing a new book and developing a new workshop, both called How to Design a LEO Network in Ten Easy Steps.

If you would like to know more about this ongoing project, e-mail me at geoff@rttonline.com or phone or message me 07710 020 040

On the RTT website there are over 280 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.
