    *  The 5 GHz Wi-Fi band offers faster speeds but shorter range, and is more sensitive to physical obstacles than the 2.4 GHz band.
    * Common causes of weak Wi-Fi include physical barriers like walls and ceilings, interference from devices like microwave ovens and cordless phones, channel conflicts with nearby routers, and poor router placement.
-   * **Too many access points close together can cause devices to hop between them, making connections unstable. Some devices will try to stay connected to multiples, which can trigger software like Acrobits softphones to re-register on many access points. This confuses where that two way handshake and audio stream should transit.  ** This might be a setting in the devices wifi settings that you can select. For example: Zebra and other commercial devices (non consumer oriented) have special WiFi Managers with complex options for commercial WiFi network implementation.  See example: https://techdocs.zebra.com/emdk-for-android/6-8/mx/wifi/
     * Positioning antennas vertically (for the same floor coverage) or at 30 degrees (for multi-story building coverage) can improve signal spread.
    * Switching your 2.4 GHz router channel to 1, 6, or 11, and 5GHz channel to 36-48 can reduce interference in environments with many overlapping Wi-Fi networks.
    * If your router’s current Wi-Fi signal doesn’t reach every corner of your location, you can add compatible devices to eliminate dead zones.
+====VoIP Specific====
+When the system has a WiFi device running Acrobits Cloud Softphone (or other softphone) registering multiple times quickly, it is often because of WiFi related issues:

 ===Symptoms===
 Weak Wi-Fi signal, slow Wi-Fi speed, **intermittent VoIP problems** or limited range.

 This narrowing effect becomes more pronounced with High-Gain antennas. Make sure the antenna is aimed precisely in the direction you need coverage, as misalignment can cause significant signal loss.

 Higher transmission rates, is essentially better performance. Signal To Noise Ration is important. Often people think more power is better, when it is often noisier. Think distorted heavy metal guitar of Wifi. Power bosters have to be installed carefully. **Mesh extenders, power line relays, and repeaters are NOT suitable for VoIP communications. They increase latency and jitter. **  The proper coverage of wired access points with good antennas suitable for the location is the best answer.
+==Extrinsic Factors==
+   * Physical barriers such as walls, floors, and partitions.
+   * Interference from other devices that use the same frequency band, such as microwave ovens, cordless phones, and Bluetooth devices.
+   * **More than one access point (AP) or wireless router operating on the same channel.**
+   * ** Poor placement of the AP or wireless router. Place the omni devices in an elevated, central location to reduce the impact of physical barriers and directional antennas in the proper orientation. **
+===Choosing the Best Antenna Location===
+. Position antennas for the best location and direction.
+For the same floor coverage, place vertical (rubber ducky style) antennas vertically, so the coverage is best on the same level. UFO/Frisbee shaped antennas are designing to be ceiling mounted, flat, as the "sector" style antenna is
+For multi-story building coverage, placing antennas at 30 degrees (diagonally) is more effective. Because antennas transmit weakly at the base, do not place your wireless client device directly below a TP-Link wireless router or access point..
+. Reduce interference from physical and electronic sources.
+Avoid physical obstructions within the wireless coverage area. Each wall or ceiling reduces Wi-Fi signal strength, particularly those containing metal or dense materials.
+Keep your device away from electromagnetic noise sources that generate radio frequency (RF) noise, such as microwaves, monitors, electric motors, and copying and fax machines.
+====Mikes Reccomendations:====
+Most consumer wifi routers work well in most small office applications. Larger locations may require 2 or more in ACCESS POINT (not router) mode. Larger locations, retail, warehouses, multi-building should have an technologist involved experiences with with the equipment they are maintaining or installing. They should have special tools (often just software on a mobile device) that helps them optimize the "controller" (brain) and "access points" (radio) so that they work together for seamless WiFi coverage for your devices and locations. There are special devices for doing WiFi surveys as well.
+Personally, I've had good results with both Unbiqiti and TP-Link systems in complex installs. Walking around and tuning the channels, coverage pattern and frequencies. Sometimes moving antennas helps.  I've seen problems with "reflection" off of metal shelves, freezers, and even walls with metal mesh in them. Seen one an office in what used to be an X-ray machine room. Lead lined walls do not pass WiFi.
+Add uncommon client devices to the mix, and that brings a new set of variables.
+Ring- can offer advice, share experience, but we are not able to be on-site. Complex locations and installs require a professional. It'll save you money and frustration in the long run. We'll help, but there are limits to what we can do.
