AirMobile enables service providers and enterprises to protect networks from wireless security vulnerabilities whether or not they deploy a wireless network.

AirMobile solution is a secure and cost-effective solution using mobile sensors to send alarms about the Wi-Fi security status.

This means you don´t have to install large amounts of sensors in complex buildings and you don’t need to worry about shaded areas as our mobile sensor will move around the buildings or area of concern. Sensors are totally automatic so they don’t need to be operated by the company’s network experts. The automation and ease of use opens doors for security industry to expand into Wi-Fi security service offerings.

WiFi Hopper is a WLAN utility that combines the features of a Network Discovery and Site Survey tool with a Connection Manager.
Sporting a comprehensive arsenal of network details, filters, RSSI graphing and built-in GPS support, WiFi Hopper is invaluable for identification and advanced characterization of neighboring wireless devices.
Additionally, WiFi Hopper can connect to unsecured, WEP, WPA-PSK and WPA2-PSK networks directly from within the application. With editable network profiles and dedicated Connection Manager execution mode, WiFi Hopper can be used as a significantly more transparent replacement for Windows and manufacturer-provided wireless clients.

KisMAC is an opensource and free stumbler/scanner application for Mac OS X. It has an advantage over MacStumbler/iStumbler/NetStumbler in that it uses monitor mode and passive scanning.
KisMAC supports several third party PCMCIA cards - Orinoco, PrismII, Cisco Aironet, Atheros and PrismGT. USB Prism2 is supported as well, and USB Ralink support is in development. All of the internal AirPort hardware is supported as well.
Please note: This program is not intended for novices, but for professional users. Take this as a warning

NetSurveyor Professional is a new type of diagnostic tool that puts a different spin on WiFi troubleshooting -- emphasizing performance metrics over measurements of RF signal strengths. NetSurveyor-Pro is used to test the performance and reliability of a WiFi network and help identify and troubleshoot problems. Furthermore, NetSurveyor-Pro also allows you to concurrently test multiple (up to five) WiFi connections. NetSurveyor-Pro is a software-only product that uses your 802.11 adapter(s) and access point(s) -- no additional proprietary hardware is required. Novices through experts will find NetSurveyor-Pro most useful when installing, testing, and troubleshooting 802.11 adapters and wireless networks. At a fraction of the cost of more expensive solutions, NetSurveyor-Pro provides a more accurate picture of a WiFi network from a performance perspective.

Ultimately, the bottom line for any network (wired or wireless) comes down to throughput performance -- that is, how many bytes-per-sec can be transferred from one node on the network to another. The dBm and RSSI values that are often referred to in the context of wireless networks don't mean much if you can't somehow relate them to a performance metric. Before we can really begin to troubleshoot a wireless network we need a way to benchmark its performance, so as modifications are made we can determine whether or not they really make a difference in the network's performance. This is where NetSurveyor-Pro comes in. It is a simple tool that allows benchmarking of one or more wireless networks.
