Worth Reading: Using multiple rates and multiple channels to improve wireless performance

9 February 2021


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.

Technology can damage our state of mind, and new research is bearing that out: Computer giant Dell Technologies, in partnership with neuroscience firm EMOTIV, put people through a gauntlet of bad tech experiences, and then measured their brainwaves to gauge their reactions.

Worth Reading: How critical are submarine cables to end-users?

3 February 2021


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.

2 February 2021


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.
