Using lasers to improve internet access

A new high-speed laser link can replace the use of fibre cables for last-mile connections

Spotted: Up to now, mobile operators and broadband providers have relied on fibre cables to deliver last-mile, high-speed connectivity. This is because existing wireless solutions cannot reach high speeds, requiring a multi-gigahertz spectrum even to reach 10 gigabits per second (Gbps). At the same time, the use of fibre cables is expensive, especially when cables need to be laid over challenging terrain such as bodies of water.

Now, Singapore telecoms company Transcelestial Technologies has an answer. The company has upgraded the bandwidth of its Centauri 10G product to reach 25Gbps by using laser beams, eliminating the need for underground cables. It is also fast to set up — the system can be deployed in as little as a few hours.

Transcelestial’s proprietary wireless technology creates an invisible laser communications network between points such as buildings, cell towers, and poles without the need for physical wires. The compact links are able to withstand harsh weather and high winds. The result is faster communications at lower costs and is especially useful for last mile communications in rural areas.

Mohammad Danesh, Co-Founder and CTO of Transcelestial explains that, “The cost to connect the world is not commercially viable if upgrades depend on the rollout of new fibre cables. Upgrading to new fibre infrastructure amid challenging terrain can slow down improvements by years. With CENTAURI 25G, we’re glad to be the first to meet the demand for reliable wireless laser links above 10Gbps and provide a much-needed solution that’s not limited by spectrum.” 

Springwise has spotted a number of innovations aiming to reduce the environmental or financial cost of delivering internet access. These include the use of a smart glass system to send data, and technology that harvests unused energy from Wi-Fi signals to power electrical devices.
