Squeezing Out More Bandwidth By Twisting Radio Waves

As data traffic grows at an increasingly rapid pace, wireless bandwidth is fast becoming a precious commodity. Enter Italian astrophysicist Fabrizio Tamburini and his proposed solution-- one involving "twisting" radio waves. 

The idea takes inspiration from the gravity black holes generate-- gravity so immense it causes light waves to twist. In a recent paper, Tamburini shows a means to twist radio waves in a similar way-- creating multiple subfrequencies distinguished by the degree of twistedness. 

You can tune the wave with a given frequency as Read more...

Wireless LAN Grows Thanks to Mobile Devices

The global Q2 2011 WLAN market (including access points and controllers) is worth $757M, shipping 1.6M units-- with 35% Y-o-Y growth, according to Canalys. 

The analyst attributes this growth to "the need for pervasive Wi-Fi connectivity due to the proliferation of mobile devices."

Internet and app use on smartphones and tablets are a key driver to the expansion of WLAN coverage in both private and public environments, together with the shift to the 802.11n standard.

The EMEA WLAN market grows by 30.7% Y-o-Y, with all industry sectors registering Read more...

Cisco Goes for Wireless Control

Cisco launches the Flex 7500 Series Wireless Controller, saying it allows network managers to manage a number of branch office WLANs without the need for a controller at each site-- reducing the number of controllers needed. 

The appliance handles up to 2000 access points across distributed sites, as well as local authentication and fast roaming. In the case of WAN failure, it authenticates on a local RADIUS server, keeping wireless clients connected. 

Features include layer 2 mobility, secure guest access and rogue access point Read more...
