The document describes traffic counter systems in RNCs (Radio Network Controllers) and cells in 3G WCDMA networks. It discusses key performance indicators for traffic, including Erlang load, throughput, number of radio bearers, and more. Counters are grouped by their measurement location (RNC or cell) and type (traffic, radio bearers, HSDPA, transmit power). The purpose is to understand and monitor traffic patterns and performance at different levels of the 3G network.
