RF Engineering

This one-day class introduces the importance of traffic analysis in the provisioning of optimum wireless networks. The course is divided into four general areas that cover terminology and background knowledge, traffic models for voice applications, traffic models for data applications, and engineering applications and techniques. The goal is to provide the trainee with sound engineering and statistical techniques useful for the appropriate allocation of traffic resources for wireless networks under a variety of operating conditions and growth scenarios. Class topics include Erlang B, Erlang C and data traffic models, traffic planning for a startup system vs. an established system, and strategies for relieving traffic congestion. Objectives  Define all units of measure in traffic engineering  Describe the concept of Grade of Service (GOS) and it's impact on the number of required voice channels  Learn how to do traffic planning in circuit switched voice cellular networks  Familiarize with implementation of data services in 3G cellular networks  Learn traffic planning techniques for data traffic in wireless cellular networks  Explain the traffic trending methodology  Explain the most important methods for traffic congestion control  Optionally – analyze traffic dimensioning in CDMA systems and packet data traffic modeling in GSM/GPSR systems. Prerequisites The student should be familiar with college level algebra and basic cellular engineering concepts.
