Wireless network monitoring essential, says Aruba Enaya: The factors affecting the performance and security of a wireless network are more difficult to track

The need to monitor wireless networks, identifying bottlenecks and potential risks, has become increasingly pressing for Middle Eastern enterprises as they continue to rely heavily on their wireless infrastructures, according to Aruba Networks.

The vendor's regional director, Ammar Enaya, said that, because enterprises depend on their networks to deliver data and applications, any failure could adversely impact the business. He added that the need to monitor wireless networks was even more important than monitoring wired ones, as more factors can impact the performance of a wireless network.

"In this area, we find that monitoring is absolutely essential. This is because, unlike in the wired network, the factors affecting the performance and security of a wireless network are far more difficult to track," he told ITP.net.

"For example, we have to provide visibility into parameters such as radio frequency, interference, noise and number of users connected per channel, per access point. Unless this information is available, the administrator would be unable to efficiently manage the wireless network."

To gain real insight into their wireless networks, Enaya suggested analysing signal-to-noise ratio, signal strength, interference and noise, as well as the types of devices connecting to access points.

However, Enaya also said that any monitoring solution that provides these networks should also provide high-quality analysis and reporting. He said that a good wireless network monitoring solution should conduct deep packet inspection (DPI) of application traffic, so that enterprises can determine whether bandwidth is being utilised efficiently.

Enaya added that comprehensive reporting was also becoming a must when it comes to wireless network monitoring. He said that logs and detailed reports can be easily referenced to identify and troubleshoot problems that are only caught at a later point.

"Take, for example, the hospitality sector. Here, a guest when checking out may only say that the internet connection was not up to standard. The IT team would then be tasked with uncovering what exactly was wrong," he said.

"Using their reports, they would be able to gain insight into the cause of the problem and take the appropriate measures to prevent future occurrences."
