Although it requires a RADIUS server to do the 802.1X authentication and is more complex to setup, it provides superior Wi-Fi security and can save you time and money in the long run.</p> <p>Here are several reasons why businesses and organization should utilize Enterprise-level Wi-Fi security.</p> Networking Security Wi-Fi Wireless LAN Network Security IDG Insider Wed, 09 Apr 2014 10:00:00 +0000 admin 240008 at http://www.infoworld.com Google asks US Supreme Court to review ruling on Wi-Fi packet sniffing http://www.infoworld.com/d/networking/google-asks-us-supreme-court-review-ruling-wi-fi-packet-sniffing-239622?source=rss_wi-fi <p>Google has asked the U.S. Supreme Court to review a decision by an appeals court that its collection of data from unencrypted Wi-Fi networks is not exempt under federal wiretap laws.</p> <p>The company argues that its data collection does not violate the Wiretap Act as it fell under an exemption that makes it lawful to intercept electronic communications that are readily accessible to the general public.</p> Networking Security Google Wi-Fi Federal Regulations Internet Privacy Wed, 02 Apr 2014 11:38:21 +0000 admin 239622 at http://www.infoworld.com HP makes printing easier, secure in BYOD environments http://www.infoworld.com/d/computer-hardware/hp-makes-printing-easier-secure-in-byod-environments-238474?source=rss_wi-fi <p>Using mobile devices for one-off printing tasks on office printers may not be a big deal, but Hewlett-Packard is trying to mitigate any security risk through direct wireless printing features it is bringing to enterprise printers.</p> Computer Hardware Hewlett-Packard (HP) Wi-Fi BYOD Printers Mobile Security Mon, 17 Mar 2014 15:15:24 +0000 admin 238474 at http://www.infoworld.com Gigabit Wi-Fi case study: Erickson Living upgrades to 802.11ac http://www.infoworld.com/d/networking/gigabit-wi-fi-case-study-erickson-living-upgrades-80211ac-236023?source=rss_wi-fi <p>Erickson Living, a company that manages 16 Continuing Care Retirement Communities in nine states, faces a unique challenge when it comes to installed a wireless network each retirement community has common areas where residents share available bandwidth, but there are also individual residential units where end users have their personal phone and Internet connections.</p> Networking Wi-Fi Wireless LAN IDG Insider Mon, 10 Feb 2014 15:35:56 +0000 admin 236023 at http://www.infoworld.com Movirtu turns your tablet or laptop into a virtual smartphone http://www.infoworld.com/d/mobile-technology/movirtu-turns-your-tablet-or-laptop-virtual-smartphone-235850?source=rss_wi-fi <p>Movirtu has unveiled CloudPhone, a software platform that lets users make and receive calls over Wi-Fi networks using their mobile phone numbers on tablets and laptops without a regular SIM card.</p> <p>Mobile operators have to find ways to compete with companies such as Skype, which offer Internet-based communications that are challenging traditional services.

But those older standards -- the once-popular 802.11b and an even slower spec from 1997 -- aren't nearly as efficient as most Wi-Fi being sold today.</p> Mobile Technology Networking Wi-Fi Wireless LAN Mobile Technology Tue, 28 Jan 2014 12:37:32 +0000 admin 235108 at http://www.infoworld.com Fon working with Qualcomm to expand Wi-Fi hotspots http://www.infoworld.com/d/networking/fon-working-qualcomm-expand-wi-fi-hotspots-234587?source=rss_wi-fi <p>With new Qualcomm-based products, more funds and a U.S. expansion, free Wi-Fi aggregator Fon expects to reach 35 million hotspots by 2016.</p> <p>Since its inception in 2006, Fon has been working to build a crowd-sourced network of hotspots, where users share their broadband connection via Wi-Fi and in return get free access to other hotspots around the world.
