Devices in wireless networks can operate on multiple channels and automatically adjust their transmission rates for the occupied channels. While a higher transmission rate potentially contributes to a higher transmission throughput for wireless applications, it may result in a smaller area being covered.
With Internet traffic increasing three-fold during the COVID-19 pandemic, we at the Indonesia Network Information Centre (IDNIC), together with the Indonesian Internet Service Providers Association, were both looking for a better way to monitor domestic routing incidents, such as route leaks and prefix hijacking. We were also interested in growth in IPv6 and RPKI deployment.
Nearly all international data is carried by a mesh of submarine cables connecting virtually every region in the world. While the initial deployments of the submarine network date back to the mid-19th century, the recent explosion of Internet traffic has driven an exponential proliferation of the total capacity required from this infrastructure.
Bringing these shifts to the radio access domain is of particular significance, given that RAN has so far driven 70% of the network capex with equipment that typically comes from one, closed incumbent supplier. With 5G and specifically Open RAN, the opportunity now exists to allow for best-of-breed innovation in the radio domain in pursuit of cloud outcomes.
