  • VMware one-ups Microsoft with vSphere 5.1

    The race for virtualisation dominance between Microsoft and VMware has become more interesting with VMware's recent release of vSphere 5.1. We obtained vSphere around the same moment as the final release of Windows Server 2012, whose newly included virtual switch and enhanced Hyper-V features were designed to clobber VMware.

  • Six home networking technologies to watch out for

    Most of the tablets, TVs, ultrabooks and smartphones on display at International CES this week ultimately are bound for someone's home, where they'll have to talk to each other. Six major home networking technologies to make that happen will be on display at the show, some of them making significant strides to keep up with the demand for instant information and fun.

  • 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.

  • Defcon Wi-Fi hack called no threat to enterprise WLANs

    Enterprise Wi-Fi networks can keep using WPA2 security safely, despite a recent Defcon exploit that has been widely, but wrongly, interpreted as rendering it useless.

  • Securing your hybrid cloud

    The debate over public cloud versus private cloud continues to rage within the IT industry. As most organisations take an ad-hoc, evolutionary approach to new technologies, the environment over the next five years is likely to be a mixture of the two.

  • Virtualisation - Don't let security lag behind technology maturity

    Virtualisation is mainstream, with virtualised servers, storage, networking and software featuring in most enterprise IT departments. Applications and workloads are assigned to virtual machines (VMs) and moved from machine to machine as a matter of course, and as a result, deploying physical servers is now the exception rather than the rule.

  • Five focus areas to keep Avaya in the race

    New Avaya data networking chief Marc Randall has five focus areas in his sights to help the company sell its Ethernet switches, gain market share... and perhaps stave off irrelevancy.

  • Rethinking software development, inspection and testing

    Setting the Scene - Where Formal Inspections Were Born: The early 1970s were a bit like the old Monty Python Skit "The Four Yorkshiremen," having a reel-to-reel tape drive was "luxury" and most people still had physical punched cards. Robert C. Martin, a co-author of the Agile Manifesto, described this era in his book The Clean Coder

  • Gigabit wireless gets closer as 802.11ac standard approved

    One gigabit wireless LAN products should enter the retail channel for the 2012 holiday season thanks to the fact that the 802.11 working group concluded balloting on the proposed 802.11ac standard last summer, meaning enterprise-focused products should follow in 2013.

  • High-speed Ethernet planning guide

    Standards-based 40- and 100-gigabit Ethernet switches and routers are starting to show up in enterprise networks, following ratification of the IEEE 802.3ba specification in mid-2010.

What to expect from 802.11AC

The extensions of the physical-layer wireless techniques pioneered in 802.11n which make up the final 802.11ac Wi-Fi standard will have a considerable impact on enterprise wireless LANs (WLANs). Use of multiple antennas will give increases in the amount of wireless bandwidth in a cell, improving throughput and giving crucial capability in environments that serve high densities of Wi-Fi clients, such as stadia and other large public venues. This trend will also vastly improve the reliability of Wi-Fi connections, making it easier to provide Wi-Fi coverage around physical obstructions like elevator shafts and stair wells.

802.11n Access Points and Power over Ethernet: Key Considerations

Farpoint Group Technical Note - The problem with current PoE technology, is that a very limited amount of power is available in compliant implementations. The idea of powering a .11n AP via .3af, however, has been met by a justifiable level of scepticism. We recently jumped at the chance to test a product that claimed to be able to accomplish this feat.

802.11n Access Points and Power over Ethernet: Key Considerations

As we have noted before, IEEE 802.1n is the only wireless-LAN (WLAN) technology that matters today. The outstanding improvements in rate, range, and price/performance now being seen in both residential/SOHO-class as well as enterprise class products, as demonstrated by our own testing, have previously led us to conclude that the time to install .11n is now and that waiting will only result in an investment in last year?s technology.

Wi-Fi Location-Based Services

802.11 wireless has truly blossomed in the past decade, moving from a technology that was primarily a productivity enhancement for verticalized industries to one now pervasive in the modern technology-aware society.
