A wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. It uses radio communication to accomplish the same functionality that a wired LAN has. WLAN utilizes spread-spectrum technology based on radio waves to enable communication between devices in a limited area, also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. |

Following a long period of development, fixed-mobile convergence (FMC) appears ready to arrive in the form of real carrier services for enterprises. The concept of FMC—the ability to access multimedia applications from a variety of end-user devices while roaming across a range of fixed-line and mobile networks—has broad appeal. Enterprises see FMC as a way to improve employee efficiency which may also help reduce telecom costs. Carriers look to FMC to help them survive and grow in a world where profits from providing mere connectivity and transport for voice and data are rapidly dwindling.

Like any network technology, wireless local area networks (WLANs) need to be protected from security threats. Though recent developments in IEEE standards have been designed to help ensure privacy for authenticated WLAN users, WLAN clients and enterprise infrastructure can still be vulnerable to a variety of threats that are unique to WLANs.

Today, resistance welding takes many forms across numerous applications in diverse market seg-ments. While each company must decide the most efficient welding technology for its various operations, the parameters that govern such decisions often change, sometimes rather quickly over short time intervals. This means decision makers must constantly monitor welding processes to ensure the right technology is applied to each application and done so in a cost effective manner.

Yesterday’s fat access points and legacy wireless LANs typically can’t handle mission-critical, real-time applications, nor do they have a migration path to 802.11n. Aerohive Networks has developed a new controller-less architecture that provides an innovative way to handle tomorrow’s wireless challenges – like voice over WLAN and migrating to 802.11n – without costing you a fortune. This paper discusses the benefits of this approach and the key underlying technologies of cooperative control, including best path forwarding and policy enforcement at the edge.

For many wireless broadband network operators, the term "unlicensed reliability" is seen as an oxymoron. For many, the idea of building a high-speed network in the unlicensed band isn't a good one. A great deal has been said about crowded frequencies, self-interference and costly network rips. About how microwaving popcorn can cause interference. About disgruntled and perplexed customers. And ex-customers.
