Performance is generally an issue with mobile data services. GPRS can provide performance equivalent to dialup (20 to 40 kbps), and CDMA 1xRTT provides higher speeds (on the order or 50 to 60 kbps). This is still much less then what can be achieved at an 802.11 public WLAN hotspot, a DSL line to your home, and certainly what you get when seated at your desk. What can be done to improve that performance? Higher speed services are starting to roll out from the mobile data operators, but this takes time. What can be done in the interim? As it turns out, there are products that will enhance the performance of the TCP protocol over the very challenging radio environment, as well as compress applications for more efficient transport over narrowband radio links. What are the issues involved in including these solutions in your enterprise mobile data environment? When and where would you use them? How well do they work? This white paper will step through each of these challenges in some detail.
