Code Division Multiple Access (CDMA) is an increasingly popular method for handling higher volumes of calls. This spread spectrum technique is resistant to inference and jamming, provides for more calls to be made on a single frequency, allows for frequency reuse, and permits soft handoffs. Evolution Data Optimized, or Evolution Data Only (EV-DO) is designed as an evolution of the CDMA 2000 standard that supports higher bandwidths, enabling a wider range of wireless data services.
Both the CDMA and EV-DO standards require an in-depth understanding for engineers to correctly and efficiently implement them. Our 3-day CDMA and EV-DO Technology course offers an in-depth look into the technology, standard, algorithms, and issues associated with the two wireless standards. We emphasize the basics surrounding each standard and delve into the current issues related to manufacturing next-generation devices.
What Will I Learn By Taking This Class?
Semitracks' CDMA and EV-DO Technology course introduces the high data rate 1xEV-DO technology. By focusing on the basics of the technologies and the issues surrounding them, participants will learn how to optimize performance and efficiently implement the standards in a wireless network.
- 1xEV-DO design philosophy and operational processes. We'll compare the performance of 1xEV-DO with competing technologies in the marketplace and explore network architecture, terminal functional architecture, and air interface operation. Additionally, the course reviews the IS-856 core EV-DO standard and the IS-871 interworking standard.
- The foundation knowledge of event processing necessary for troubleshooting and optimization of 1xEV-DO networks. The course describes the behavior of 1xEV-DO Subscriber Access Terminals and the Access Points of the EV-DO network over the air interface in both Rev. 0 and Rev. A modes. System Acquisition, Idle Mode, and Connected State. We'll also review the Physical and MAC layer steps, indications, and Layer-3 Messages.
- The objectives, philosophy, and steps involved in optimizing the over-the-air performance of 1xEV-DO networks. The course describes the key performance indicators and the 1xEV-DO parameters requiring optimization to obtain best performance. We'll fully explain the role of the RF environment in 1xEV-DO problems.
- Rationale and strategies for managing the RF environment. We'll cover example field test data showing normal and abnormal operation and events. Throughput and latency performance of 1xEV-DO networks depends not only on the RF environment, but also on the basic performance of the IP network beyond. Basic techniques are discussed for determining whether data problems are the result of air interface impairments, AP/RNC configuration problems, or IP network problems.
This course is appropriate for engineers and technicians in equipment manufacturers designing 1xEV-DO products and network operators building and optimizing 1xEV-DO networks. Our instructors work hard to explain the standards without delving heavily into the complex computer science algorithms that normally accompany this discipline.
- The seminar will provide participants with an in-depth understanding of CDMA and EV-DO technology and its use in today’s high volume wireless data applications.
- Participants will understand the basic concepts behind the two standards.
- The seminar will explain the IS-856 core EV-DO standard and the IS-871 interworking standard.
- Participants will work a wide variety of sample problems to help them understand the fundamentals of the two standards.
- Participants will learn the objectives, philosophy, and steps involved in optimizing the over-the-air performance of 1xEV-DO networks.
- The seminar gives participants the opportunity to use CDMA and EV-DO equipment and see the code and behavior first-hand.
- Participants will be able to make decisions about how to construct and evaluate CDMA and EV-DO wireless networks.
Our courses are dynamic. We use a combination of instruction by lecture, problem solving, experimentation with CDMA/EV-DO equipment, and question/answer sessions to give you the tools you need to excel in the failure analysis process. From the very first moments of the seminar until the last sentence of the training, the driving instructional factor is application. The course handouts offer hundreds of pages of reference material that the participants can apply during their daily activities.
Our instructors are internationally recognized experts. Our instructors have years of current and relevant experience in their fields. They're focused on answering your questions and teaching you what you need to know.
