Preparing your wired network for wireless network integration
This article is part of the Network Evolution issue of April 2011 Vol. 2, No. 2
In the first part of this series, we discussed how to make the business case for integrated wired and wireless LANs. In this tip, learn how to make the necessary upgrades to the wired network to prepare for wireless network integration. Today's 802.11n WLAN products hold distinct advantages over Fast Ethernet for enterprise network access. Pulling cable to offices and cubicles can take weeks and cause costly damage to walls and ceilings, while activating new wireless "ports" can be done without structural change or delay. Furthermore, in hard-to-cable venues like cafeterias and courtyards, 802.11n can be more desirable than Fast Ethernet for LAN traffic aggregation. For example, two 40 MHz-wide 5 GHz channels can backhaul half a gigabit of application traffic. Better yet, wireless mesh APs can automatically find the best backhaul path to the wired network's core, relaying traffic through neighboring APs to bypass temporary outages.

As iPhone OS Wi-Fi clients proliferate in the enterprise, IT must troubleshoot iPhone Wi-Fi connection problems and a host of other iPad WLAN problems. Here's how to solve basic iPad and iPhone Wi-Fi connection problems.
Tablets are taking the enterprise by storm, and tablet security is a major concern. Find out which mobile device security best practices you're already using can apply to tablets, and which you will need to revisit to keep tablets secure.
Wireless LAN integration means upgrading wired networks with new equipment and traffic prioritization to avoid bottlenecks between the networks and provide QoS for wireless multimedia applications, including WLAN voice and video.
Enterprise Wi-Fi coverage is a key aspect of communications infrastructure planning as dual-mode smartphones and mobile handsets replace desk phones. Successful Wi-Fi strategies must incorporate hybrid technologies like DAS, femtocell and FMC.
Combining wired and wireless LAN security solutions may be a plus for smaller companies, but larger enterprises fear security integration could result in vulnerabilities.
