India's Homegrown System for "Fixed Wireless" Has Legs

A novel way of providing plain old connected telephone service wirelessly is concocted in Chennai (Madras)

1 July 2003—No copper? No problem. Systems for connecting customers to the telephone system wirelessly rather than by means of the tried-and-true copper loop can be an attractive option in areas that have yet to set up a copper infrastructure. One such system, developed at the Indian Institute of Technology (IIT)�Madras (Chennai), is being extensively deployed in rural parts of India and has already attracted serious interest in a dozen other countries, including South Africa, Brazil, Russia, Egypt, and Iran.

Methods of providing local telephone service via radio connections to the home or office are generally referred to as ”fixed wireless” in the United States, or ”wireless in local loop” in India. The IIT system, called corDECT, was developed by a telecommunications and computer networking group under Ashok Jhunjhunwala, a professor of electrical engineering.

When the COVID-19 pandemic erupted in early 2020, the world made an unprecedented shift to remote work. As a precaution, some Internet providers scaled back service levels temporarily, although that probably wasn’t necessary for countries in Asia, Europe, and North America, which were generally able to cope with the surge in demand caused by people teleworking (and binge-watching Netflix). That’s because most of their networks were overprovisioned, with more capacity than they usually need. But in countries without the same level of investment in network infrastructure, the picture was less rosy: Internet service providers (ISPs) in South Africa and Venezuela, for instance, reported significant strain.

But is overprovisioning the only way to ensure resilience? We don’t think so. To understand the alternative approach we’re championing, though, you first need to recall how the Internet works.
