is given of a possible scenario where load balancing can be useful the access points ap 1 ap 2 and ap 3 as shown in fig1 give for the network station different signal reception levels srl and average noise levels anl and different traffic loads att in this example a linear cost function will be used to keep matters simple but it is to be understood that non linear functions also may be applied also for simplicity the comparison of average noise levels nlap and nlst observed by an access point and the network station respectively is omitted here the resulting values anl obtained as described in step 43 of fig4 are given here directly in the table below the network station 39 s signal reception level srl with respect to each access point its average noise level anl with respect to each access point channel frequency used and each access point 39 s averaged traffic load att are given clearly the traffic load in the network is somewhat unbalanced assume the network station 5 is associated with access point ap 1 in the connected scan state further assume that the weight factor weight is 0 5 as an example the value for the connected scan state and the load of the network station autt is 10 the threshold value thv is 30 30 db signal to noise ratio when the beacon frame is received step 41 the processing unit will calculate the cql value of the associated access point using steps 42 and 44 according to the description of fig4 according to equation 1 the value of cql is 13 in step 45 comparison of cql with the threshold value thv shows that cql is smaller than thv.
