Teletraffic engineering is a necessary field in telecommunications network planning to ensure that network costs are minimised without compromising the quality of service delivered to the user of the network. This field of engineering is based on probability theory and can be used to analyse mobile radio networks as well as other telecommunications networks. This article discusses the mobile cellular network aspect of teletraffic measurements. Mobile radio networks have traffic issues that do not arise in connection with the fixed line PSTN. It must be noted that a mobile handset which is moving in a cell will record a signal strength that varies. This signal strength is subject to slow fading, fast fading and interference from other signals, resulting in degradation of the carrier-to-interference (C/I) ratio.[1] A high C/I ratio yields quality communication. A good C/I ratio is achieved in cellular systems by using optimum power levels through the power control of most links. When carrier power is too high, excessive interference is created, degrading the C/I ratio for other traffic and reducing the traffic capacity of the radio subsystem. When carrier power is too low, C/I is too low and QoS targets are not met

Important aspects of cellular traffic include: quality of service targets, traffic capacity and cell size, spectral efficiency and sectorization, traffic capacity versus coverage, and channel holding time analysis.

I'm thinking blood cells in the capillary network of the body?!!!
LOL
Naw, the answer above is what you're looking for...hehehehee.
