Mapping your wireless local area network: How to make your WLAN shine

This guide offers advice on optimizing your WLAN performance and reliability

This essential guide addresses the basics of wireless local area network (WLAN) and examines the steps enterprises need to take to improve the performance and reliability of their existing -- and future -- WLAN infrastructures.

BYOD

1. Maximizing the mobile workforce

We are living in the age of mobile workers -- employees who bring their own devices to work and expect to be able to use them while on the go. In this section of our guide, learn how to successfully support wireless local area network access even as the "bring your own device" (BYOD) phenomenon continues to grow.

  • WLAN troubleshooting for BYOD

    The BYOD era is upon us. Do you have a plan? Optimizing security is only half the battle when it comes to supporting a BYOD-tailored wireless LAN. The rest relies heavily on WLAN troubleshooting to guard against draining critical network assets. This feature details steps you can take to ensure you're practicing the most proactive BYOD WLAN troubleshooting tactics.

    Feature

  • Provisioning WLAN access for BYOD takes combined tools

    IT shops lacking resources to manually configure hundreds of personal devices are put in a tough position. Asking users to "do it yourself" can lead to security breaches and other problems. It is possible to automate wireless LAN access provisioning for BYOD with the right tools -- and this tip can help.

  • Penn tackles WLAN access for 46,000 BYOD clients

    As thousands of new students and their devices arrive on campus each fall, large universities face a particular challenge in managing BYOD. At the University of Pennsylvania, administrators have to handle up to 46,000 clients and 20,000 concurrent connections. In this tip, learn how to integrate WLAN features with mobile device management tools.

    Expert tip

  • Creating a WLAN architecture for a mobile workforce

    To deploy a robust wireless local area network architecture, start by evaluating a range of WLAN access control technologies and edge designs. In this tip, learn about the basics of WLAN access control, the proprietary extensions vendors offer to differentiate their products and more.

    Tip

  • Assessing the enterprise WLAN for the mobile workforce

    As the number of wireless devices and mobile workers continues to grow, does it make sense to run Ethernet to workspaces if employees are using mobile devices as their primary computing tools? Network engineers must reassess the business and technology needs behind building a distributed enterprise wireless LAN to support a mobile workforce.
