  • How much faster will 802.11ac wireless data really be?

    Six months from now, enterprise IT groups will be facing a big change for their Wi-Fi networks: the shift to 802.11ac, which promises wireless data rates that start at 433Mbps.

  • A simple guide to gigabit wireless technology

    Today's existing state-of-the art wireless LAN can achieve 300Mbps using 802.11n with two spatial streams. Future developments will deliver three- and four-stream speeds of up to 600Mbps. But the 802.11 working group has set its sights on a more ambitious milestone: 1 Gbps throughput.

  • The future of wireless networking architecture

    With ever more devices needing greater throughput for video and voice content, today's wireless hub-and-spoke network architecture is showing its age. What's needed is a wireless LAN (WLAN) solution capable of greater intelligence at the network's edge to optimise traffic flow without compromising security or quality of service and driving up cost.

  • A guide to ARP spoofing and WPA2

    AirTight Networks says it's found a weak point in Wi-Fi Protected Access 2 (WPA2), the mainstay of enterprise Wi-Fi security. But has it? Security expert Matthew Gast says the attack seems to be a familiar ARP spoofing exploit that works as well on wired as wireless LANS. If so, it can easily be contained.

  • Timeline: 802.11n development milestones

    Here?s a snapshot of how efforts to create a 100+Mbps wireless LAN standard got started.

  • Cheaper or better? Vendors fight for 802.11n

    Did you think 802.11n was done and dusted? Aruba claims it can get massive speed boosts without breaking the standard, while Ruckus says its architecture allows it to slash prices

  • What's really happening at Bluesocket?

    The wireless LAN vendor that refused to die is still confident - we spoke to the CEO about 802.11n and staff cuts

  • Is fixed-mobile convergence worth the bother?

    FMC is usually presented as a Holy Grail, but how much do we really want it? For many people, it's a lot of work for not much benefit.

  • Will Belden treat Trapeze right?

    The cabling company bought the WLAN vendor - will it be happy ever after?

  • Cisco makes a bid for practical WLANs

    Cisco's big WLAN announcement isn't about the radio technology. It's about making it easier to get applications running.

The foundation for wireless without compromise

In this white paper, we have discussed the three phases of WLAN architecture evolution i.e. WLAN for convenience (limited adoption), WLAN as the network of choice (instead of wires) and WLAN for business critical applications. We have also compared legacy microcell architectures to Meru?s Air Traffic Control? architecture and provided guidance on selection of the right architecture.

Practical Considerations for Deploying 802.11n

Two major issues to consider when planning for 802.11n are power consumption and WLAN architecture. It is important to select an 802.11n solution that operates at full dual-concurrent 3x3 MIMO when using 12.95 Watts. Siemens is the only vendor supporting fully functional 802.11n within the 802af PoE standard.
