An access point for use in a point to multipoint wireless network comprising the access point and a plurality of subscriber modules, the access point comprising: a sector antenna arranged to receive signals from a sector of an area of coverage of the access point at a first polarisation and at a second polarisation, different from the first polarisation; an antenna array of antenna elements, the antenna elements not including the sector antenna, and the antenna elements being arranged to receive signals from the same sector as the sector antenna at a third polarisation and at a fourth polarisation, different from the third polarisation; a first beamformer configurable to form a first beam from signals received at the antenna array at the third polarisation; a second beamformer configurable to form a second beam from signals received at the antenna array at the fourth polarisation; a selector switch switchable to at least a first state and a second state, wherein the selector switch is configured such that in the first state of the selector switch, signals received at the sector antenna at the first polarization are connected to a first receiver and signals from the second beamformer are connected to the second receiver , and in the second state of the selector switch, signals received from the first beamformer are connected to the first receiver and signals received at the sector antenna at the second polarization are connected to the second receiver ; and a scheduler configured to set the selector switch to the first state for at least a first receive timeslot and to set the selector switch to the second state for at least a second receive timeslot. a sector antenna arranged to receive signals from a sector of an area of coverage of the access point at a first polarisation and at a second polarisation, different from the first polarisation; an antenna array of antenna elements, the antenna elements not including the sector antenna, and the antenna elements being arranged to receive signals from the same sector as the sector antenna at a third polarisation and at a fourth polarisation, different from the third polarisation; a first beamformer configurable to form a first beam from signals received at the antenna array at the third polarisation; a second beamformer configurable to form a second beam from signals received at the antenna array at the fourth polarisation; a selector switch switchable to at least a first state and a second state, wherein the selector switch is configured such that in the first state of the selector switch, signals received at the sector antenna at the first polarization are connected to a first receiver and signals from the second beamformer are connected to the second receiver , and in the second state of the selector switch, signals received from the first beamformer are connected to the first receiver and signals received at the sector antenna at the second polarization are connected to the second receiver ; and a scheduler configured to set the selector switch to the first state for at least a first receive timeslot and to set the selector switch to the second state for at least a second receive timeslot. <EOS>
