But it can be interesting. One just showed up in an 18 June 2021 press release -- super wi-fi.

The press release came from Singapore-listed ISDN Holdings, whose core business is providing automation solutions to industries.

ISDN announced it is partnering Whizpace, a super wi-fi solutions provider spun off from Singapore’s national research organisation, Agency for Science, Technology and Research (A*STAR).

Let's get familiar with what super wi-fi is. 

1. Super wi-fi, also known as TV White Space (TVWS), are wireless spectrums in the TV bands that are not fully utilised by licensed services such as TV broadcasts and are made available to other users on a secondary basis.

DrOhSerWah WhizpaceDr Oh Ser Wah, CEO of Whizpace.2. There is endless demand for wireless spectrums but limited supply of it which leads to a spectrum crunch.

3. Meet Whizpace: It 
says its super wi-fi solutions can reach long distances of up to 10km and penetrate through obstacles. "These distinct features make previously challenging applications finally possible."

Whizpace’s connectivity products are the result of over 10 years of patented R&D.

4. Whizpace's addressable market: "
We aim to connect an estimated 3 billion people that are currently unconnected while also addressing the potential opportunities in the Internet-of-Things (IoT) and smart city markets."

Industry 4.0 must deliver intelligence and connectivity to every corner of the enterprise, including the fields, mines, transport pipelines and other wide-area spaces where many of the world’s biggest industries operate.

"Whizpace’s patented TV band connectivity fills an important gap in ISDN’s portfolio of industrial connectivity technologies. By providing reliable, low-energy connectivity in the 2km to 10km+ range, Whizpace allows ISDN to deliver important automation solutions to farming, transportation, utilities, pipelines, and other wide-area industrial operations.”

They bring not just 30 years of deep solutions experience with industrial automation, but also a formidable customer base of over 10,000 enterprises throughout Asia, along with a powerful sales force and access to hundreds of automation technology vendors and components.”
