Power Up WiMAX Base Stations in Wireless Broadband Services
2007-Enterprises, Internet Service Providers, and Mobile Network Operators are all looking for cost-effective ways to move voice and data among multiple, separate locations at broadband speeds. Copper and fiber optics solutions often fall short due to up-front costs, recurring leases from telecommunications companies, and a lack of flexibility to scale with the operating organization. Broadband Wireless Access (BWA) in WiMAX technology has emerged as a means to fill these gaps and to provide a lower total cost of ownership than wired solutions.
snom technology Launches Interoperability and Technology Partner Program
New program addresses market demand for plug-and-play VoIP solutions by ensuring interoperability between manufacturers.
PoE Plus Installed on Trains and Public Transit System
Korenix provided a total solution that met the increased demand for industrial products to connect IEEE802.3af/t PoE compliant units to Ethernet-enabled devices. The Korenix JetNet 4706 Managed PoE Plus Switch combines with WiMax network devices on the trains in Europe to provide the business persons the best mobile sevice. Mobility is of course the key to the success of mobile systems and now users can travel at high speeds through a cellular networks on a train or public transit system and enjoy an uninterrupted connection as they are handed over from one mast to another.
Power over Ethernet: How High Can You Go? The 60W Standard Is Nearly With Us.
An informative article on the progress of PoEPlus by Daniel Feldmanon Product Line Manager, Microsemi; Voting Member, IEEE802.3; PoE/PoE+ Technical Committee Chairman, Ethernet Alliance.
The Tolly Group & Sifos Technologies; PSE Testing Comparison
The increasing use of PD equipment such as VoIP and wireless access points has to assume that the selected Power Sourcing Equipment works to the 802.3af standard. Recent test by Sifos Technologies shows that you have to look deeper into a PSE rather than just the data sheet. The Tolly Group worked closely with Sifos Technologies to study two different PSE's extensively and to report on observed ranges in performance in categories such as Static Power Delivery, Transient Power Delivery, Safety, Power Management Behaviors, and Interoperability Characteristics. Approximately 50 different parameters were analyzed with many surprising results.
Application Note on Electrical Transient Immunity for Power over Ethernet
Texas Instruments have produced a white paper that is aimed to help designers prevent damage to their devices from external unwanted voltage sources. Common and differential mode examples of induced voltages are discussed as well as ESD and EFT. The abstract is printed below.
Power over Ethernet - The Reality of Designing a Powered Device
There have been many technical articles, white papers and product application notes that explain the theory on how to make a powered device. They give an overview of the IEEE 802.3af standard for Power over Ethernet and explain how to extract the power from the CAT5e cable. The following is a practical guide to help take that information and to design a PoE enabled powered device.
Power over Ethernet – The Last Frontier in Industrial Communications Standards
Perhaps the final frontier in the battle for dominance in industrial communications between field buses and Ethernet, is the ability to transmit power and data across the same wire. Shared use of cabling reduces costs, and in some applications, is the only viable solution for extending power to the very edge of an industrial operation.
Phihong's PoEPlus Midspan Family Meets New Proposed IEEE802.3at Specs
Phihong USA is offering a broad line of high-power Power-over-Ethernet midspans providing up to 33.6W per port that are in full compliance with power specifications released in draft 3.0 of the IEEE802.3at that was approved for ballot at the end of March. Available in single-, 4-, 8- and 16-port models, the high-power midspans meet the latest specifications for POEPlus in the IEEE working group that is close to finalization.
This latest unit Supports IEEE802.11n Access-Points, PTZ Security Cameras, WiMAX Transmitters, Thin Clients and Video-Phones.
