Abstract: The invention concerns a compound of the Formula I wherein m is 1-2 and each R1 is a group such as cyano, halogeno, trifluoromethyl heterocyclyl and heterocyclyloxy; R2 is trifluoromethyl or (1-6C)alkyl; R3 is hydrogen and R4 is, (1-6C)alkyl or (1-6C)alkoxy; or pharmaceutically-acceptable salts thereof; processes for their preparation, pharmaceutical compositions containing them and their use in the treatment of diseases or medical conditions mediated by cytokines.

Abstract: A method and system for estimating the number of transceivers in a service area (100) are disclosed. A calibration area (102) is selected from the service area, and a defined number of transceivers are placed in the calibration area. Input parameters are determined for the defined number of transceivers, which are refined so as to ensure that the input parameters satisfy a customer-specified requirement. The measured input parameters for the refined number of transceivers are used to calibrate a Radio Frequency (RF) coverage prediction tool for the calibration area. The calibrated RF coverage prediction tool is further used to estimate the number of transceivers in the service area.
