Can you be sure that your applications will perform acceptably over a wireless network before you roll them out into production? How well will your wireless applications deal with the dropped connections and bandwidth constraints that wireless users have to contend with in the real world? Can your developers validate application behavior in real-world wireless environments in the early stages of development?
Wireless and cellular networks introduce a unique set of impairments that can dramatically impact an application’s performance and functionality. These impairments include:
- Differences in bandwidth constraints as users move closer or further away from wireless base stations
- Connection problems as users pass from one cell to another
- Performance issues that occur when users lose “line-of-sight” access to the base station
Wireless and cellular network impairments present a whole new set of challenges to developers, QA professionals, and network designers. At the same time, overcoming these challenges has become increasingly critical as people become more dependent on wireless services to stay productive and meet business needs.
That’s why anyone who develops, tests, maintains or supports business applications must be able to accurately determine how well those applications will perform over wireless enterprise and/or carrier networks.
A Virtual Wireless Environment for Testing, Planning and Troubleshooting
In the past, many organizations attempted to test their wireless applications by setting up their own dedicated cellular network – sometimes by creating a number of pico cells in the lab. This approach, however, is very expensive, inflexible, and inaccurate.
Shunra VE offers a far more cost-effective and flexible solution. 
It accurately replicates conditions on the wireless network – including mobility, inter-cell handoffs and loss of line-of-sight – along with traditional network impairments such as latency, jitter, packet loss, and bandwidth limitations – over an Ethernet LAN, enabling testers to use PC-based cellular emulators to validate applications with ease from the earliest stages of the development and testing lifecycle.
With Shunra VE its easy to create “mobility scenarios” that let you to model the end-users’ actual quality-of-experience as they move across and between cells. You can also create “what if” scenarios to effectively plan for increases in utilization, making it an ideal solution for both network managers and developers.
With Shunra VE, you can effectively ensure the performance of all of your critical wireless applications before you roll them out on the production network - without the need to build a dedicated cellular testing environment.
- Discover application design flaws early in the development cycle to avoid project delays and cost over-runs
- Assess the impact of new wireless applications on existing ones to avoid disruption of critical services
- Avoid unnecessary infrastructure investments by modeling the impact of proposed network build-outs and/or improvements on end-to-end application performance
- Reproduce intermittent performance problems in the lab to ease troubleshooting and improve service levels
- Establish an application certification process for cellular and wireless networks
