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.

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 technology topic From Smoke to Smart Phones telescopes one million years of communications history into 1000 words.

For additional articles on wIreless history go to our wireless heritage page which includes our
recent article on the 100th anniversary of the first radio transmission between the UK and Australia on September 22 1918

This will be commemorated by events both in Australia and the UK.

Our thanks to the Overseas Telecommunications Veterans Association and David Solomon for providing additional material on the Australian National Broadband Network.

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.
