1. A base station for controlling access by wireless devices of mixed types to an uplink frequency channel comprising:

  • a transmitting antenna;

    a receiving antenna;

    a despreader which receives a composite spread signal from the receiving antenna and uses unique codes to partially despread the composite spread signal, each unique code corresponding to a particular wireless device;

    a first processor for determining the type of each particular wireless device; and

    a second processor for updating a current load value and a population value for each type of wireless device, the second processorstoring the current load values and population values for each type of wireless device;

    determining a current load share for each type of wireless device;

    determining a population share for each type of wireless device; and

    determining an equivalent current load value and an equivalent population value for all types of wireless devices admitted by the base station, wherein the equivalent current load value is proportional to the sum of the current load shares and the equivalent population value is proportional to the sum of the population shares, andwherein indicia of the equivalent current load value and the equivalent population value are sent to the transmitting antenna for transmission to wireless devices.
