GPRS | EGPRS Design and Optimization Training:
GPRS | EGPRS Design and Optimization Training Course Hands-on (Online, Onsite, and Classroom Live!)
If you have a working knowledge of the air interface and operation of GPRS | EGPRS systems, through prior experience or training, and are ready to focus on advanced engineering issues, this GPRS | EGPRS Design and Optimization Training course can help you achieve an enhanced quality of experience for your data services subscribers
Wireless operators have, in recent years, pushed to provide data services to subscribers to help broaden their revenue base as well as the subscribers’ mobile experience. Wireless and cellular/PCS technologies have traditionally been designed for circuit-switched, voice-oriented traffic. So with the introduction of data comes the challenge of designing a network that provides superior quality of service for both voice and data users across the same, contended air interface.

- If you are familiar with some aspects of GPRS | EGPRS Design and Optimization Training, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the GPRS | EGPRS Design and Optimization course around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the GPRS | EGPRS Design and Optimization Training course in a manner understandable to lay audiences.
- Understanding voice versus data
- Deterministic and random
- Data services and a mix of data
- Voice versus data for system performance
- Standards overview
- GPRS/EGPRS nodal and interface definitions
- GPRS/EGPRS nodal and interface definitions
- GPRS bearer and signaling: Definitions, groups, and mapping of:
- RLC/MAC layer
- Random access requests and packet queuing notifications
- GPRS message sequence
- Attached request
- PDP context activation
- Primary/secondary PDP context
- GPRS homing
- Location areas and updates
- Routing areas and updates
Systems Engineering Considerations
- Mapping bearer traffic to total traffic: Class will walk through several real-world scenarios showing the impact of signaling overhead to various coding schemas
- Simple estimations of throughput with various time slot configurations: Class will be asked to predict and collectively model in simplistic terms throughput for various timeslot allocation with the effect of IP packet error rate to arrive at a simple, estimated throughput calculation
