backtotop.gifTraining Course Description

Course Description

  • This training course addresses the needs of engineers and technicians who need to enable packet data applications on top of GPRS and UMTS.
  • The training course first introduces the student into the details of TCP/IP and its application protocols and operation. This section is followed by pointing out the different options for IP address allocation and advanced TCP/IP operation.
  • The next part clearly lines out the differences between the different Packet Data Protocols that are supported by GPRS and UMTS.
  • The training course concludes with the consideration of TCP/IP-performance measurements and possibilities to determine this performance in the wireless environment.
As in all INACON training courses we integrated several interactive exercises for a perfect learning experience.

Some of your questions that will be answered

  • Why is the TCP back off mechanism critical in the wireless environment
  • What can we do to minimize its impact in case of cell reselections?
  • Does it make sense to allocate private IP-addresses to our mobile subscribers? What are the implications of using Network Address Translation?
  • What is the difference between the GPRS application protocols PPP and IP?
  • How can we implement a virtual dial-up service to an external ISP over our network?
  • What is required to establish VPN access for our volume customers?
  • How does IPsec operate? How can we implement it in our network?
  • What options are there for authenticating a user? What differences are there between PAP/CHAP and RADIUS?
  • How can we measure and improve the performance of our GPRS-network?

backtotop.gifWho should attend this class?

  • Everybody who needs to optimize GPRS networks.
  • Everybody who needs to understand the implications of merging IP and 3GSM.
  • Content and Service Providers of Mobile Packet Data


  • A basic understanding of TCP/IP is required.
  • A basic understanding of GPRS and UMTS data transmission characteristics is required.

backtotop.gifTraining Course Target

  • The student is enabled to understand and judge the behavior and specific problems of TCP/IP in the wireless environment.
  • In addition the student learns the different options for allocating IP-addresses to mobile subscribers, incl. through VPN-access. In that respect, the student also learns about IPsec.
  • The student will be enabled to effectively communicate to content providers and IT-people when it comes to the configuration, restrictions and benefits of potential services for 3GSM packet data networks.
