One of the most important factors in a successful VoIP or unified communications implementation is ensuring that adequate server processing horsepower and network bandwidth exist to handle the load. Streaming audio and video are less tolerant of latency and packet fragmentation, and the infrastructure has to be capable of meeting the demands of unified communications. Mike Stacy, Director of Professional Services for Evangelyze, has created an OCS Capacity and Bandwidth Calculator. The calculations to determine the number of users a given server can support, or the bandwidth capacity necessary for those users to use unified communications technologies are contained in an Excel spreadsheet which Stacy makes available for free.

If you have ever set up or worked with a wireless network, you are probably familiar with the fact that the signal quality isn’t always the best. Depending on your wireless networking hardware and how you have it configured, the layout and materials used in the structure your network is in, and possible interference from other electronics and communications equipment, the wireless network connection can be erratic. The same can be said for those who may have worked with or set up a VoIP communications system. The issues are different, but the problems still arise with bandwidth and signal quality. It can be difficult to maintain the quality of voice communications over a VoIP network. Imagine then what types of issues you might encounter if you try to implement a VoIP communications system over a wireless network. Yikes! On May 1, Cisco is presenting a webcast entitled Extending VoIP to Wireless LAN’s which will cover six technical challenges you must address, capacity planning, roaming, security issues, and more.
