1. Why HC should be applied!

2. Center for TeleInFrastructure 2 Network Provider’s view  Increased quality of service for the user  Delay (web pages, download)  Bandwidth  Cost (?)  Capacity  Installed cells can support more users  $  Cells that will be installed with larger coverage, which results  $

3. Center for TeleInFrastructure 3 Network Capacity  How can a network provider calculate its potential saving?  A very simplified view  Thumb rule

4. Center for TeleInFrastructure 4 Notation  P = mean payload size  H_u = uncompressed header  H_c = compressed header  RR = Ratio = no. of users with HC / total number of users.  G: Capacity gain. Capacity gain can be defined e.g. how much more users in percent we can serve if some of them will activate HC (total number of users with HC activated / total number of users without header compression)
