  1. Why would Engenius not build it's own Wireless Access Points Enclosures? It will be good for our client's who's AP's are installed on hazardous or extreme environmental conditions.
  2. Lighting is one of Nature's brutal force that can cause damage to anything it struck. You can read this tips that might save your Outdoor AP's from being a victim of Nature's wrath: Antennas are magnets for static electricity in the environment. The element of an antenna and its ground structure collect energy through exposure and channel it through the access point to get rid of it. The best way to avoid damage to your antenna is to choose one that can be safety grounded to the support structure. This is primarily a concern with dish or large panel antennas. For smaller antennas, the ground of the antenna connector (the outermost exposed part of an RP-SMA or N type connector) should have a cable wiring it to ground.
  3. Here's some tips on how you can maximize the range of the DuraFon. Range depends upon the environment, but below are some guidelines: 1) 12 floors in building penetration 2) 250,000 sq. ft. in a warehouse or retail store 3) 3,000 acres on a farm or ranch The range can be maximized by: 1) Mounting the terminal base antenna as high as possible and away from obstacles. 2) An external base antenna can be used to provide coverage outside or to get above obstacles. 3) The optimal performance, tall handset antenna will provide about 20% more coverage than the low profile, stubby antenna. 4) If using an external antenna, be sure the antenna is mounted high and away from other antennas and obstacles. Be sure any remaining coaxial cable is un-coiled and laid flat in large 6 - 8 foot loops.
  4. Answer: The DuraFon Pro offers some improvements and new features over the DuraFon 4 X, including: Speakerphone capability of the PRO handsets Multiple base registration (allowing 2 way / broadcast with all), whereas the 4x is limited to base specific Up to 90 hasndsets in a system compared with 36 max. for the 4X Broadcast through a line port Supports the DuraWalkie for direct handset-to-handset operations
  5. Answer: What does Industrial Cordless mean? A. Industrial Cordless Phone Systems are designed for demanding business environments. Industrial Cordless Phone Systems offer: Long-range cordless and two-way capabilities Secure, private communication utilizing digital spread spectrum with frequency hopping technology of over 200 channels per second Digital, full duplex Two-Way Radio communications independent of the base unit Expandability External antenna capability Multiple line capacity Multi-user capability Call hold and call transfer capabilities Examples of customer applications: DuraFon 1X system connected to a PBX extension. This system is connected to a PBX system to serve as a remote call device for the administration office in a small community in Canada's North West Territories. The system is intended to allow the user to connect with one of the extensions in the main office, so when officers are out in the community, calls directed through the office extension can be received or made remotely via the DuraFon handset. Because the PBX extension is digital, and the DuraFon requires an analog connection, an analog line was configured on the PBX, and the system user simply forwards their extension to the "blind" analog line that the DuraFon 1X system is connected to when they leave the office.

    What is 5G?

    5G is a new network system that has much higher speeds and capacity, and much lower latency, than existing cellular systems. The technologies to be used in 5G are still being defined, but there are some general themes everyone agrees on. 5G networks will use a type of encoding called OFDM, which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though. The new networks can use frequencies as low as old TV channels, or as high as "millimeter wave," which are frequencies that can transmit huge amounts of data, but only a few blocks at a time. 5G may also bring in Wi-Fi as a seamless part of a cellular network, or transmit LTE-encoded data over Wi-Fi frequencies, which is called LTE Unlicensed. 5G networks are much more likely to be networks of small cells, even down to the size of home routers, than to be huge towers radiating great distances. Some of that is because of the nature of the frequencies used, but a lot of that is to expand network capacity. So 5G networks need to be much smarter than previous systems, as they're juggling many more, smaller cells that can change size and shape. But even with existing macro cells, Qualcomm says 5G will be able to boost capacity by four times over current systems by leveraging wider bandwidths and advanced antenna technologies.
  7. LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices. However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission. LiFi data is transmitted by the LED bulbs and received by photoreceptors. Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x. You can click the link below to give us better understanding on what's the difference between Wi-Fi and Li-Fi. https://www.quora.com/What-is-the-difference-between-lifi-and-wifi
  8. Directional antennas- as the name implies refers to signal coverage in a specified direction. Unlike omnidirectional antennas, directionals must be aimed in the direction of the signal transmitter or receiver which can be for example a router or WiFi hotspot. When it comes to aiming the antenna the user must be right on the signal for the best strength and quality. The way to ensure your aim is best is to know the width of the reception cone in which the antenna has. A good way to start without seeing actual lab data or knowing the specs is to judge by the dBi (decibel isotropic) rating. The higher the dBi rating the narrower the reception cone and knowing these data points you can then begin to narrow down the right antenna for you. As a rule of thumb to remember, high dBi rating = further distance covered but not area. Omnidirectional antennas are most commonly are used to create hot spots by transmitting a signal over a large area in all directions or receiving signals in all directions when the transmit location is unknown or close by. Omni WiFi antennas do not need to be pointed since their radiation cone is 360 degrees, working in all directions. Each specific antenna has a gain rating or dBi (decibel isotropic) number which coincides with the performance. The higher the dBi rating the larger the area the signal covers. Keeping that in mind and thinking about what your specific needs are you can begin to narrow down what antenna is best for you.
  9. Are we allowed to assist customer in upgrading the firmware through CLI, if he or she insist?
  10. Are Tri-Band Wireless-AC Routers Actually Faster? How many wireless client can it handle per band?
  11. Do we have an upcoming router 802.11ac wave 2 capable router?
  12. I would say you may or may not reset your AP/Bridge/Router after a firmware upgrade. I think it is not necessary to manually push the reset button because you can restore the settings back to factory default on the GUI itself.
  13. @Lee10114 Yes we do have AP/Bridge that supports Mesh Network. As of the moments, the model that support it are ENH1750EXT & ENH90EXT, which happened to be an outdoor AP's.
  14. Here's an article from @Jason D. Hintersteiner (just click the link below) that explains what fast roaming is. With regard to your 2nd question, If I'm not mistaken it will still work even if you're not using Enterprise/Radius authentication. http://www.networkcomputing.com/wireless-infrastructure/wifi-fast-roaming-simplified/1993108957
  15. When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is 100 meters or 328 feet.
