What is 4G? WiMax and LTE don't qualify

If someone is trying to sell you 4G wireless these days, don't believe them. The truth is, neither WiMax nor LTE (Long-Term Evolution) qualify as 4G (fourth-generation) technologies, according to the International Telecommunication Union Radiocommunication Sector (ITU-R).
A simple guide to 802.1x networking security

Understanding what the IEEE 802.1x standard is and why you should care means understanding three separate concepts: PPP, EAP and 802.1x itself.
A guide to ARP spoofing and WPA2

AirTight Networks says it's found a weak point in Wi-Fi Protected Access 2 (WPA2), the mainstay of enterprise Wi-Fi security. But has it? Security expert Matthew Gast says the attack seems to be a familiar ARP spoofing exploit that works as well on wired as wireless LANS. If so, it can easily be contained.

802.11n Access Points and Power over Ethernet: Key Considerations

Farpoint Group Technical Note - The problem with current PoE technology, is that a very limited amount of power is available in compliant implementations. The idea of powering a .11n AP via .3af, however, has been met by a justifiable level of scepticism. We recently jumped at the chance to test a product that claimed to be able to accomplish this feat.

802.11n Access Points and Power over Ethernet: Key Considerations

As we have noted before, IEEE 802.1n is the only wireless-LAN (WLAN) technology that matters today. The outstanding improvements in rate, range, and price/performance now being seen in both residential/SOHO-class as well as enterprise class products, as demonstrated by our own testing, have previously led us to conclude that the time to install .11n is now and that waiting will only result in an investment in last year?s technology.
