GPRS Training Fundamentals

GPRS Training Fundamentals


GPRS Training Fundamentals Course Description

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 GPRS Training Fundamentals 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.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
