Why has 802.11 flourished while Bluetooth has essentially failed? Should we even care about Bluetooth? The crux of the problem is that 802.11 represents the Internet and Bluetooth represents the faux ...

Fig 1. Among the protocol stack layers for IEEE 802.15.4, only layers 1 and 2 belong to the standard, while the upper layers are defined by the specific protocol (e.g., ZigBee, 6LoWPAN, and ...

The latest update to the Wi-Fi protocol standard, 802.11ax, has been designed to transmit data even faster, to better negotiate bandwidth among several computers and other devices connected to a ...

Wi-Fi is everywhere and we can’t really do without it. But the current-gen Wi-Fi standard is limited to data transfer between devices, and with every new iteration, we just see better speeds and ...

Implementing applications with wireless networking is becoming commonplace. From consumer devices to industrial applications, there is a growing expectation that our devices will have built-in the ...

In response to reader requests for a refresher in basic wireless LAN operations, I’ll finish up a discussion I began last time of 802.11 WLAN channel assignments and user access. Some of you have ...

A designer of wireless applications has multiple choices of standards and protocols ranging from the simple to the amazingly complex. The most familiar choices are Bluetooth and Wi-Fi. Bluetooth has ...

Two security organizations have issued alerts warning of a flaw in wireless LAN equipment based on the 802.11b Wi-Fi standard that leaves the devices vulnerable to a denial-of-service (DoS) jamming ...
