A material for 3D printing is described. The material comprises a polymeric composition comprising a thermoplastic polymer; and from 50 to 99 wt. % ceramic particles comprising a metal, wherein at least 50% by weight of the particles have a diameter in a range from 10 to 100 &#x3bc;m; wherein the material has a dielectric strength of at least 5 kV/mm and/or a dielectric constant of at least 5.

Material for 3D printing and a 3D printed device

A fiber-radio communication network includes a base station () and wireless access nodes () coupled by fiber optic cables (). The base station () includes a switch module () arranged to switch Ethernet signals on a local area network, and a media converter rack module () comprising media converter units MC1-MC6 arranged to convert between a baseband Ethernet signal carried by the fiber optic cables () and an Ethernet digital signal for the switch. The wireless access node () comprises a media converter module () which converts between a baseband Ethernet signal carried by the fiber optic cables and an Ethernet digital signal; and a wireless access point module () comprising a local modem which converts between the Ethernet digital signal received over the fiber optic cables and a wireless transmission in a 60 GHz range for wireless communication with a client terminal () in the vicinity of the wireless access node ().

Fibre-radio communication network and apparatus and fibre-radio communication method

An analog modem circuit and carrier recovery method are disclosed for use between an RF receiver and a digital modem circuit configured for receiving a baseband RF input signal, and including an up-converter with frequency supplied by an up-converter voltage controlled oscillator, VCO; a down-converter with frequency supplied by a down-converter VCO; a Costas loop sub-module; and baseband outputs from the down-converter to a digital modem circuit. The up-converter feeds the down-converter, and the Costas loop module performs Costas loop functionality on the output of the down-converter to control the up-converter VCO frequency output to thereby control modification of rotation of symbols of the baseband signal.
