    Below are some SFP modules that have been tested either internally or by community members and reported to be working with EnGenius EGS/EWS Switches.

    Hi shalobelle, The model was phased out for a long time from EnGenius. As I remember, commanding via console port is the only way to reset unit to factory default. The document from you mentioned link is great and clear, but i am not sure the baud rate is "57600" or not. You could try other rate number once "57600" selected is not workable.

    To address the pressing demand for speeds surpassing 1Gbps ahead of completion of the IEEE 802.3bz standard, the NBASE-T Alliance, a 45+ member consortium of industry leaders representing all aspects of the ecosystem, is developing prestandard specifications and products in parallel, and in tandem, with the IEEE process. Using NBASE-T specifications, users may begin deployment of 2.5GBASET/5GBASE-T technology today. Individuals from NBASE-T companies have been key contributors at every stage of the IEEE process. As a result, the 802.3bz draft standard relies on a technology baseline similar to the NBASE-T specification. End users, therefore, can have a reasonable expectation of a seamless transition to the IEEE standard when it is ratified. NBASE-T 和 IEEE802.3bz 技術和量測.pdf

    IEEE 802.3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. This is generally a local area network technology with some wide area network applications. Physical connections are made between nodes and/or infrastructure devices (hubs, switches, routers) by various types of copper or fiber cable. 802.3 is a technology that supports the IEEE 802.1 network architecture. 802.3 also defines LAN access method using CSMA/CD. http://standards.ieee.org/news/2015/ieee_802.3bz.html

    Hi Caila, Due to the different mechanism on SW side, the WDS connecting throughput may be greater than AP-CB connection. The difference may exist 10~20Mbps difference.

    http://blog.csdn.net/zhandoushi1982/article/details/4603443 Here is the introduction for the bad block issue of the NAND flash. Nand flash is the good choice for the flash. Because it has large capacity, cheap. but in the same time, it has the bad block issue.

    Trending products. http://www.androidpolice.com/2016/07/06/exclusive-google-is-building-two-android-wear-smartwatches-with-google-assistant-integration/ QUOTE: Speaking to Android Police, a reliable source has told us that Google is currently building two Android Wear devices - possibly Nexus-branded - for release some time after the latest Nexus phones are announced. One watch will be larger, sportier, and more fully-featured (LTE, GPS, heart rate), the other will be smaller and lack the aforementioned mobile data and GPS.

    The user cannot set Daylight Savings Time on his ENS202EXT. He cannot set the day setting beyond the 6th. Fix: It is only up to 6th because it is describing the nth week not the particular day of the month. For example DST for USA would be like: Start: March 2nd Sunday 2am which is March 8, 2015 2AM End: November 1st Sunday 2am which is November 1, 2015 2AM

    The LEDE(Linux Embedded Development Environment) project is a Linux based embedded meta distribution based on OpenWrt and targeting a wide range of wireless SOHO routers and non-network devices. https://www.lede-project.org/ The LEDE announcement was sent on May 3 by Jo-Philipp Wich to both the OpenWrt development list and the new LEDE development list. It describes LEDE as "a reboot of the OpenWrt community" and as "a spin-off of the OpenWrt project" seeking to create an embedded-Linux development community "with a strong focus on transparency, collaboration and decentralisation." https://lwn.net/Articles/686767/

    Nice formula! It seems to be based on the inverse square law (1 / x^2). http://hyperphysics.phy-astr.gsu.edu/hbase/forces/isq.html However one thing to note is that it is for free space loss, meaning direct line of sight and in outer-space. So if you were calculating for a transmission from Earth to Mars, then this formula can work well. However on Earth ground level, you have things like gases in the atmosphere (air), how much water vapor (humidity) is in the gas can impact signal propagation. This will change with altitude. Also for outdoors long distance reflections from the ground, and diffractions from surrounding objects also impact the signal retention. http://www.wirelesscommunication.nl/reference/chaptr03/pathloss.htm For indoors, need to consider building materials...... http://ftp1.digi.com/support/images/XST-AN005a-IndoorPathLoss.pdf There are many things to consider, hence answering "how far can I transmit" is not so easy to answer.

    Depends on your settings. Below are the 3 options you can use to authenticate connected users. Choose "Splash & Go" and connected users won't have to authenticate upon logging on. Choose "ezMaster Authentication" and connected users will be authenticated using ezMaster's internal user database. Choose "RADIUS Server" and connected users will be authenticated using the user defined RADIUS server.

    How about EnGenius devices supporting Facebook WiFi. It is like having a captive portal using a Facebook account. Companies with guest networks and would like to promote themselves would probably like to have Facebook WiFi.

    For EWS Switches that were launched before 2014: EWS2910P/EWS5912FP/EWS7928P/EWS7928FP/EWS7952FP First numeric digit is for the form factor of the device 2: Desktop 5: 13" 1U Rackmount 7: 17" 1U Rackmount Second numeric digit is fixed at "9" Third and fouth digit is the total number of primary and secondary ports. P/FP is for total PoE budget P = half PoE, only half the number of primary PoE ports can support 15.4W PoE output simultaneously (although all primary PoE ports are PoE capable) FP = full PoE, all primary PoE ports can support 15.4W PoE output simultaneously For EWS Switches that were launched after 2016: EWS1200D-10T, EWS1200-28T, EWS1200-52T
