Abstract: A node 100 for a communications system comprising a plurality of nodes is disclosed. The node 100 comprises a plurality of antennas each configured to transmit and/or receive a beam for communications with other nodes of a communications system. The at least one beam deflector is located in a housing 104,106 detachably attached to an external portion of the node 100. The or each beam deflector is located and arranged to deflect a beam transmitted and/or received at one of the plurality of antennas.

Abstract: A wireless node (10) comprises an RF modem (12), an RF switch array (14) connected to the RF modem (12), the RF switch array (14) comprising a layer of circuit board (18) sandwiched between layers of conductive material (20, 22) and a plurality of antennas (16) connected to the circuit board (18) of the RF switch array (14) via waveguides (36) present in the layers of conductive material (20, 22), a first subset of the antennas (16) arranged in a first horizontal plane H1 and a second subset of the antennas (16) arranged below the first horizontal plane H1 in a second horizontal plane H2.

Abstract: A wireless node comprises a central core (100) of interlocking horizontal layers of circuit boards and conductive material comprising, from bottom to top, an RF modem comprising a layer of circuit board (24) sandwiched between layers of conductive material (26, 28), a duplexer (30) connected to the RF modem, and an RF switch array connected to the duplexer (30), the RF switch array comprising a layer of circuit board (18) sandwiched between layers of conductive material (20, 22).
