Abstract: A switchable element, a device and a method for analogue and programmable computing operating on electromagnetic waves having a frequency, wherein the switchable element is configured to configured to, in response to an activation signal, switch from having a first dielectric permittivity for electromagnetic waves having a frequency to having a second dielectric permittivity for electromagnetic waves having the frequency, and the device comprises a plurality of the switchable elements that are adapted to be switched individually in accordance with the computing operation.

Abstract: This document discloses a solution for performing channel selection for a wireless network. According to an aspect, a method comprises: detecting, by a first network node, at least a second network node; determining, by the first network node, a primary channel of the second network node and a set of channel bonding configurations supported by the second network node, wherein the set of channel bonding configurations defines one or more configurations for combining the primary channel with auxiliary channels; determining, by the first network node, channel utilisation factors of the second network node for a set of frequency channels by using the set of channel bonding configurations; and selecting, by the first network node, a primary channel on the basis of the channel utilisation factors.
