Abstract: Disclosed is a solid phase method of synthesising biomolecule-drug-conjugates (e.g. antibody-drug-conjugates) using photocleavable moieties. The method comprises: (i) providing an immobilised photocleavable group-biomolecule conjugate; (ii) optionally contacting the immobilised photocleavable group-biomolecule conjugate with a chemical modification agent or activating agent to provide an immobilised photocleavable group-biomolecule conjugate that is chemically modified or activated at the biomolecule portion; (iii) contacting the immobilised photocleavable group-biomolecule conjugate of step (i) or the chemically modified or activated immobilised photocleavable group-biomolecule conjugate of step (ii) with a drug component to form an immobilised photocleavable group-biomolecule-drug-conjugate; and (iv) irradiating the immobilised photocleavable group-biomolecule-drug-conjugate of step (iii) with radiation thereby releasing the biomolecule-drug-conjugate.

Abstract: A cellular communications service provider authenticates a provider of a location-dependent service, such as a wireless hotspot. Once the cellular communications service provider is aware of potential use of the service by the user, it authenticates the service provider and provides an authentication to the user. Users can thus avoid untrustworthy providers of local services.

Abstract: Access to a wireless data network to nodes located in a defined operational area is limited by transmitting a network signal within the defined operational area while transmitting a wave that can cause destructive interference with the network signal into a prohibited area adjacent to the defined operational area. The wave that can cause destructive interference is produced by phase and/or amplitude modulating the network signal. The modulation of the network signal includes sweeping the phase and/or amplitude.

Abstract: A network adapter capable of receiving data from a network, said adapter arranged to receive data at at least a lowest and a highest rate; said adapter comprising: sampling means arranged to sample said data; an equalizer arranged to receive, and equalize, said data samples, and said equalizer capable of being trained to equalize data, at at least, each of said lowest and highest data rates; and training means capable of training said equalizer to equalize data; wherein; said adapter is initially arranged to train said equalizer to receive data at said lowest data rate allowing data to be decoded and if upon decoding said adapter determines that said equalizer has been trained to equalise data at the incorrect rate to retrain said equalize to equalize data at the correct rate.

Abstract: An error correction method and apparatus passes received data onto higher system levels only if both a CRC check is determined to be valid and the forward error correction performed on the received data is determined to be valid.

Abstract: A wireless local area network comprising a plurality of computing entities communicating over a common communications frequency within a local area network operates a transmission deferral method whereby each computing entity defers its own transmissions if it receives a signal at said communications frequency which is above a threshold value set within said computing entity, and which is decodable. Each computing entity is capable of varying dynamically the value of its threshold level above which receipt of signals results in the computing entity deferring its own transmission. Received signals on the communications frequency which are less than the threshold value do not result in the computing entity deferring its transmissions, but are ignored by the computing entity. The threshold value is varied according to whether traffic from more remote signal sources are sufficiently intense that the local traffic cannot be decoded.
