802.11n is delivering on promises to bring revolutionary advances in throughput and capacity to the wireless LAN. For the first time in the history of the development of IEEE 802.11 networks, wireless LAN speeds are comparable to commonly used wired technologies. Now that wireless LAN users have access to speeds well in excess of 100 Mbps, wireless LANs can no longer be treated as an afterthought.
Today's de facto standard architecture is commonly referred to as the, “controller-based” architecture, sometimes referred to as the “split MAC” architecture. It involves one or more controllers and controller-based (lightweight, thin) APs. The controller-based architecture was created to solve manageability, mobility (as opposed to portability), control-plane inadequacies, and high operational expenditure (OPEX) problems that were prevalent in autonomous (fat, thick, standalone) AP implementations. Find out how to eliminate the need to redesign your network in order to introduce a controller-based overlay infrastructure. That’s one less thing to manage, and one less thing to pay for.
While all Wi-Fi vendors understand the need for and are taking steps in the directions of a fully-distributed architecture, crossing the bridge from controller-based to controller-less takes a significant amount of time and effort because all system features and the user interface must be re-architected for a fully-distributed platform. We invite you to take the road less traveled: controller-less. Read on.
Security of a wireless network still ranks as one of the largest concerns of IT professionals planning to roll out an enterprise wireless LAN. Many people erroneously believe that a wireless LAN is inherently insecure. This is largely due to security flaws in early Wi-Fi protocols like WEP (Wired Equivalency Protocol), more recent vulnerabilities found in TKIP and lack of awareness as to how to deploy a secure WLAN. This whitepaper will help the wireless network administrator or security manager to understand the security capabilities in a modern Wi-Fi solution, where they should be used and how the WLAN integrates with other security devices in the network.
Mobile Internet Devices (MIDs) are easily the most exciting development in computing devices in the post-laptop era. By combining portability near to that of a phone with a larger screen, it is possible to interact with much larger data sets and to perform previously inaccessible computing tasks. From the user perspective, one set of credentials is used on all devices, including MIDs. However, only corporate-owned devices have access to the corporate network. Personal devices can be restricted to only Internet access, or can be given access only to a restricted set of resources such as a virtual desktop infrastructure. Read on.
Before Wi-Fi protocol analyzers, administrators and consultants alike were only able to troubleshoot by continually reviewing the network design of and device operation within the network infrastructure. With the introduction of Wi-Fi protocol analyzers, these professionals had the equivalent of RF goggles. They could now see what was happening and could reactively troubleshoot problems. Read on.
Although residential Wi-Fi applications are a primary focus for these 802.11ac technologies, they will also have a considerable impact on enterprise wireless LANs (WLANs). Both increasing the wireless bandwidth in a cell and the trend towards multiple antennas will make it easier to provide seamless Wi-Fi coverage around physical obstructions, such as elevator shafts and stair wells.

Four trends continue to drive changes in the field service market: an increased focus on workforce optimization, improved service quality levels, a move to more flexible software models (for example, software as a service or cloud), and wireless mobility. Read on.
SonicWALL and CIO magazine’s custom solutions group recently conducted a series of facilitated conversations with dozens of CIOs and senior IT executives throughout the
United States. The upshot: Most IT leaders are now building their technology infrastructure for growth. Their issue: How to seize new business opportunities while mitigating risk.
