| Cisco helps avoid security scrimping in cash-tight times Many Wi-Fi vendors have integrated dedicated wireless intrusion prevention systems (WIPS) directly into their 802.11n systems. Cisco, for example, recently released an application called Adaptive Wireless IPS integrated with a multifaceted attack correlation system in its Wireless Control System (WCS) network management and security policy platform. 802.11n support added to wireless intrusion defense Existing wireless-LAN intrusion-prevention systems have a blind spot: Until they're upgraded, they can't detect radio signals from 802.11n WLAN gear. Companies pair PoE with wireless IPS PowerDsine partnered with AirTight Networks this week to bring together PowerDsine's equipment for supporting Power over Ethernet and AirTight's wireless intrusion-prevention systems. Space invaders: You and WIPS This situation points to the need for a wireless IPS even if you haven't implemented wireless LANs internally, because all of your new notebooks have built-in wireless. Sprint WiMAX Begins the Era of True Wireless Broadband How fast does mobile Internet need to be for to you give up the wired connection you're probably using right now? Should You Upgrade to Faster Wi-Fi? What it is: There's a new Wi-Fi option waiting in the wings. Enterprise vendors such as Motorola and Cisco have recently started promoting gear that supports the 802.11n specification, which runs at about 100 megabits per second (Mbps). Meanwhile, the next generation standard--802.11n 450, based on chip sets made by Marvell, could easily top 200Mbps of throughput under ideal conditions. Sprint to deploy WiMAX in 10 U.S. cities in 2009 Sprint plans to deploy its WiMAX services to 10 major U.S. cities in 2009, with five additional major markets due to get services in 2010. Cisco zeroes in on e911 Cisco Subnet blogger Dennis Hartmann explains how the the ability to move mobile devices within a location without administrator oversight makes emergency calls difficult to track - and how the Cisco Emergency Responder may change this.
