In various embodiments, pollution is reduced by associating a pollution credit with a consumer product or service. The values of EBNO are stored in a look up table in the BTS and each mobile; the BSC generates values of semi static rate matching factors and spreading factors for each service and transmits them to the BTS and mobiles so that the mobile can calculate from the received values and the values stored in the look up table the number of bits to be punctured or repeated. The input threshold voltage of the second inverter is set up at a lower level than the low-level offset potential of the first inverter as the level of supply voltage Vdd falls below a predetermined reference level. The antenna module is attached to a radio receiver. A video latency time is determined for transmission of the video signals over the computer data network.
