Wi-Fi / WLAN / 802.11 channels, their channel frequencies and bandwidth allocations around the globe, spectral mask and summary of which channels can be used together for WLAN solutions. The IEEE 802.11 Wi-Fi / WLAN standards set the attributes for the different channels that may be used. These attributes enable different Wi-Fi modules to talk [...]
Remote Authentication Dial-In User Service (RADIUS) is commonly used to provide centralized authentication, authorization, and accounting for dial-up, virtual private network, and, more recently, wireless network access. This article provides an overview of RADIUS and the Extensible Authentication Protocol (EAP) and discusses how to minimize or resolve various security issues of the RADIUS protocol using [...]
When building your wireless network some basic installation techniques and rules must be followed to ensure optimal performance. The bullets below outline some of the basic steps that are required for a successful installation.
