| Introduction: |
| |
GPRS is the first technology to introduce packet switching to the world of mobile communications
in a meaningful, large scale context. As such, it adds two major, equally important, elements, viz., (i) packet
switching over the air interface and (ii) enhancements to the core to support packet switching on a GSM network.
Implementing packet switching over a highly unreliable and time varying channel, such as is typical in today’s
wireless communications, is not an easy task. In this course, you will learn how GPRS tackles this problem and
achieves a reasonable performance using packet switching over the air interface. You will also learn the new interfaces
that were necessary in the fixed portion of the network to support an end-to-end packet switched service. We will
not be shy about highlighting the shortcomings of GPRS, some of them quite serious. We will go on to learn which
of these shortcomings can be mitigated (along with how that’s done) and which are unsolvable within the framework
of GPRS |

| Audience: |
| |
| Engineers experienced in GSM who wish to learn more about GPRS. The standard presentation of
this course assumes a bachelor of science in Electrical Engineering, Mathematics, Physics, or a related subject
along with an appropriate background in communications. |
| |
| Prerequisites: |
| |
- Working knowledge of wireless network structure and operation, RF propagation and fading
issues, and link budget analysis
- Working knowledge of packet switching and associated networking problems and solution approaches
- At least two years experience in the design and optimization of a wireless network using
any major technology

| Customize it: |
| |
| This 3-4-day GPRS course will be customized to your needs and specifications. Eno.com will assist
you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training.
They will typically have a broad and general course, one size fits all, already developed and just put your organization’s
name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your
exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the
beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”,
one size fits all, class. |
