Omnipliance for analysis and performance monitoring of the entire WLAN traffic
New Gigabit wireless technologies require new monitoring solutions
Wireless networks are used everywhere and the number of connected devices is growing exponentially. A quick Google search reveals that, every day, billions of devices are tethered. If you depart from the “Internet of Things”, these estimates are too small.
We’re also experiencing another Wi-Fi revolution in terms of the speed and capacity of wireless network infrastructures. With the introduction of 802.11ac, WLANs are now moving in Gigabit speed range and introducing new versions of 802.11ac should easily see data rates up to 6,93Gbit/s.
Wireless users are excited about this new transmission speed but the rapid expansion of WLANs causes considerable difficulties for those who are responsible for managing Wireless Local Area Networks (WLAN). The solutions and methods that worked for 208.11a/b/g networks with 54Mb/s are out of date and can’t be adapted to today’s Wi-Fi technology. New solutions and methods must be found to ensure the performance and safety of 802.11ac networks.

Flexible data collection in high-speed networks
Mobile analysis has been a common approach for wireless analysis for the last two years. OmniPeek’s WLAN analysis software can be switched to listening mode along with special wireless adapters to simultaneously analyse data packets on multiple channels. Field engineers and IT consultants greatly value this type of software since mobility is one of the most important requirements.
The number of wireless networks is increasing constantly and managers need reliable 24×7 monitoring solutions for WLAN environments. If you use remote analysis, on-site troubleshooting is superfluous and you can easily evaluate errors together with other important safety aspects regardless of your location. OmniPeek’s remote analysis uses the existing network infrastructure to evaluate wireless data through the analytical processor. Using the remote capture process, information needed to monitor the access point via the existing LAN infrastructure can be forwarded to the appropriate administrator’s PC. This approach is always useful if the problem isn’t located in your immediate vicinity.
Distributed WLAN analysis
For distributed WLAN analysis in distributed and larger WLAN environments, data to be captured for analysis can be easily forwarded through WLAN Controllers to the Omnipliance Wi-Fi solution in just a few steps. Continuous and uninterrupted Wi-Fi analysis takes place locally within Omnipliance. This approach is particularly recommended for networks with a large volume of Wi-Fi data and in dispersed operating environments.
Omnipliance’s dispersed WLAN analysis enables you to carry out uninterrupted continuous Wi-Fi traffic recording. You can then analyse wireless problems in real time or through the process known as WLAN forensics. Using wireless forensics, you can shorten your response times to service shortfalls and failures, which helps to increase availability while saving IT costs. WLAN forensics is of great benefit in mission-critical environments and also enables security analyses to be carried out.
The advantages of OmniPeek professional wireless
WLAN capture from any location – independent of technology
WiFi networks are widely dispersed. In most cases, it’s almost impossible to be there on the spot when the problem has been reported. You must be able to remotely collect and analyse data with what’s out there and record wireless traffic over the latest wireless devices, including 802.11ac 3-stream and 4-stream. OmniPeek provides just the right support that you need to do this. No other product offers this level of flexibility.
Display who is connected and the APs used
Before beginning an analysis, you first need to get an overview. The wireless aspect in OmniPeek helps you to display all available networks, including which APs are supplying which networks and which clients are connected through which APs. You can also see in detail all associated configuration information (bands, channels, security settings, signals, noise, data rates, etc.).
Detailed analyses, suitable for any situation
Using its unrivalled fully fledged analytical skills, OmniPeek can trace the cause of any problem in your WLAN. OmniPeek’s applications range from dealing with problems such as poor availability or complete loss of an AP, to complex problems such as intermittent dropouts for individual BYOD devices.
Multichannel analysis – transparency for all Wi-Fi traffic
Most WLANs are operated on several channels to prevent each AP from interfering with the others. Analysis solutions that only consider individual channels don’t provide the level of detail essential for analysis and troubleshooting. Your WLAN analysis solution must be able to record all data simultaneously on several channels with no gaps and this is exactly what OmniPeek does!
Expert events – alarms when wireless problems occur
What use is WLAN network analysis when you need to spend all your time sitting in front of it? A solution that’s efficient, runs around the clock and performs the complete analyses for you leaves you free to attend to other important things. When problems occur, you’re notified immediately and can then take action quickly. OmniPeek provides more than 50 different wireless-specific expert analysis functions that continuously monitor and analyse your WLAN for you.
Roaming analysis – analyse past events as if they had just happened
Wireless networks are designed for mobile applications and this infrastructure is becoming increasingly important for users because it now also runs business-critical applications. As analysts, we know that we’re dealing with a broad range of problems, which we’ve never come across in traditional LANs. Once users connect to a wireless network, roaming will be “the” problem that has the greatest impact on user satisfaction. Passing from AP to AP (known as hand-off) takes time. Although a variety of 802.11 standards and enhancements have been introduced, this can cause serious problems for the user, such as bad VoFi (voice over Wi-Fi) quality due to falling VPN connections. OmniPeek’s permanent and 24/7 WLAN analysis identifies and records all roaming activities, whether these are from AP to AP, from channel to channel, or both. It reports on the roaming times from clients and APs and, with just a single click, displays detailed and transparent roaming activity with accuracy to the millisecond.
Filters only the relevant data
The Network Analyser captures large amounts of data very quickly. OmniPeek is obviously capable of this but, when it comes to analysing the data, smaller datasets can be much easier to manage, especially when you know exactly where to find what you’re looking for. OmniPeek allows you to set filters before you start recording so the data collected will be reduced or temporarily filtered out so it can be shown more easily. The collected data remains completely unaffected, so you can change the filter if necessary to find exactly what you’re looking for.
OmniPeek provides over 100 built-in filters, of which about half are specially designed for WLANs. Custom filters can be easily created using a graphical kit and integrated immediately.
Manage BYOD using rogue detection
Given the rapid development of BYOD (Bring Your Own Device) distinguishing friend and foe in your WLAN is an essential task. OmniPeek helps you to do this by using independent device classification. Once you’ve classified a device, it’s stored in the OmniPeek name table and is always recognised and classified in the same manner. Devices can be trustworthy (Trusted), known (Known) or unknown (Unknown). Trusted devices are usually your own or those over which you have control. Known devices may be, for example, neighbouring APs in that you know they’re there, but have no control over them. Unknown devices should always be examined because these could include prohibited or malicious IEDs (rogue devices).
