  • Cisco Cius: A hands on preview

    Toss all preconceptions of the Cisco Cius out the door. This is not just another Android tablet. Instead, Cisco has taken great pains to position the Cius as a very different type of tablet. This is one device whose primary purpose lies less in competing head-to-head with the tablet masses, and more at changing how the enterprise does business.

  • 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.

  • Rivals offer switch alternatives to Cisco

    Cisco have dominated the enterprise switching market for years. Can other vendors muscle in with better value products, or will Cisco's market clout hold off all-comers?

  • The five best router and switch features that you don't use

    Don't fork out on unnecessary products, the feature that you're looking for could be on your existing switch or router and you've not found it yet. Here's the rundown of five of the most needed.

  • 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

  • Does Motorola's 802.11n kit put it back in the Wi-Fi game?

    Motorola took its time bringing out an 802.11n AP for its enterprise Wi-Fi, but it may not be too late for the product to make an impact.

  • 802.11n access points on the starting blocks

    With few customers as yet, 802.11n Wi-Fi vendors are going to get very competitive about the performance of their kit.

  • 802.11n won't happen overnight

    Faster Wi-Fi is on its way - but it needs more electricity. Could that delay it seriously in business?

  • Which way to NAC?

    Choosing between stand-alone NAC and building it into the infrastructure.

  • Cisco switches don't make the grade, say US universities

    Cisco's dominance in enterprise networking doesn't necessarily mean it is the only game in town ? or that you jeopardise job security by bypassing Cisco.

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.

3Com® Power over Ethernet Solutions

Simply stated, Power over Ethernet (PoE) provides a way to distribute low-voltage power across the network using existing Ethernet data cabling. This centralized, reliable source of power enables network devices such as IP telephones, wireless access points, and network jacks to operate without additional power adapters, cords, or AC outlets. PoE isn?t a new concept. Until now, the only real issue has been the lack of a standard implementation scheme. The demand for voice over IP (VoIP) telephony and wireless LAN (WLAN) has resulted in a number of different, and often incompatible, inline power solutions currently being offered on the market.

3Com Soultions: Power over Ethernet

Organizations gain the convenience and cost-savings of reduced power cabling when they take advantage of Power over Ethernet (PoE). This centralized, reliable source of power enables network devices such as IP phones, wireless access points, and network jacks to operate without additional power adapters, cords, or AC outlets. Using PoE-compliant devices, they can take advantage of low-voltage power distributed across a network on existing Ethernet data cabling.
