‘CENTAURI’ – Transcelestial’s laser communications systems

Transcelestial Singapore based startup founded by, Rohit Jha & Mohammad Danesh have developed a CENTAURI’s wireless laser communications technology that is reliable, secure connections for essential applications across a range of industries. ISPs.

Transcelestial’s laser communications systems do away with underground cables, which are expensive to install and maintain, and radio-frequency-based devices, with their complicated spectrum of licensing regulations. As a result, Jha said Transcelestial can offer a significantly lower cost per bit option. Transcelestial’s shoebox-sized devices, called CENTAURI, have already been deployed in South Asian and Southeast Asian markets.

The startup recently proved that its laser technology can deliver 5G connectivity during a demonstration at the University of Technology Sydney. Its next stop is space: Transcelestial is working on bringing its technology to a low-earth-orbit (LEO) constellation, with the goal of deploying its wireless fiber optics from orbit directly into cities and downs.

Transcelestial is on a mission to make the internet more accessible by building a network of shoebox-sized devices that send lasers to one another, creating a fiber-like network.

Fastest time to market
No spectrum approval needed. No right of way required. Rapidly connect point-to-point with line of sight over distances from 200 m to 3 km and beyond, in less than a day per link. Flexibly expand your network edge to better utilise the capacity of your fiber infrastructure.

Cost effective
Spectrum Costs? Zero. Integrated with commercial off-the-shelf components and network management systems. CENTAURI can augment existing capacity or help rapidly extend coverage ahead of permanent fiber installation.

High bandwidth and throughput
From 1Gbps to 10Gbps, CENTAURI’s high-throughput technologies support modern network traffic levels that would overwhelm traditional RF/mmWave, older generations of FSO and satellite communications

Centauri’s laser-light technology provides low-latency, highly secure connectivity, preventing signal interception and disruption from jamming. Build redundant links and disaster recovery capabilities to ensure business continuity in the most challenging scenarios.

Advanced AI tracking & control
CENTAURI’s patented telemetry and AI-based tracking system automatically adjusts alignment and laser power in near-real-time, with micro-scale precision. Maintain and improve link performance over time, in a variety of environmental conditions, including rain, pole sway or vibrations.

Compact and easy to deploy
CENTAURI looks as good as it performs. Older FSO technology was large, heavy, hard to deploy, and used enormous amounts of power. CENTAURI is sleek, weighs less than 2.5kg per device, deploys in less than 4 hrs, and requires only 25-32W of power to run.

Future proof
CENTAURI uses lasers in the 200 THz spectrum, supporting nearly unrestricted headroom for future upgrades and the ability to scale to 100s of Gbps transmission rates in the future. This technology can scale with you, as your bandwidth needs grow.

Transcelestial has proven that it is possible to deliver 5G connectivity wirelessly using laser technology at a 10Gbps capacity. The technology showcase took place at a new demonstration site at the University of Technology Sydney (UTS Tech Lab).

Transcelestial launched the new public 5G demonstration facility in collaboration with UTS Tech Lab, along with partners – Mavenir, a leading global Open-RAN vendor, and ALLDAS Solutions, an Australian wireless technical consultancy group, specialising in next generation in-building coverage solutions and use cases.

The demonstration took place at UTS Tech Lab, which has one of Australia’s largest near-field antenna anechoic chamber, and conducts cross-layer research into 5G/6G technologies and systems. These facilities allowed the demonstration to model and analyse next generation technologies via reliable, high capacity, low latent and highly secure communications. The demonstration captured a 5G signal on site A, and via two of Transcelestial’s CENTAURI devices mounted on rooftops sent it to site B using CPRI protocol which housed a Mavenir multi carrier, multi band Remote Radio Unit, delivering 5G signals to multiple devices.

CPRI – Common Public Radio Interface

The purpose of CPRI is to allow replacement of a copper or coax cable connection between a radio transceiver (used example for mobile-telephone communication and typically located in a tower) and a base station (typically located at the ground nearby), so the connection can be made to a remote and more convenient location. This connection (often referred to as the Fronthaul network) can be a fiber to an installation where multiple remote base stations may be served. This fiber supports both single and multi mode communication. The fiber end is connected with the transceiver device called Small form-factor pluggable transceiver.
