 ====== AREDN ======
-  * [[https://www.arednmesh.org | AREDN]] is a project aimed at using wifi devices to create a computer network independent of the internet.  Since hams have access to sections of the 2.4GHz and 5.8GHz bands that regular wifi devices don't, those channels are quieter and longer distances can be achieved with better antennas.

 ===== Getting Started =====
-The easiest way to get started is to get a Microtik hAP AC Lite TC.  Once flashed with the AREDN firmware, the device will use the 5.8GHz band as a regular wifi for your computer to connect to, and the 2.4GHz band is used to mesh with other devices within range.  Realistically, the hAP is useful to tunnel to others on the network via the internet to get started.  To add RF links, an outdoor device will need to be added.  See the [[https://www.arednmesh.org/content/supported-platform-matrix |support matrix]] for more information.
+The easiest way to get started is to get a [[https://mikrotik.com/product/RB952Ui-5ac2nD-TC|Microtik hAP AC Lite TC]]. One can be purchased from [[https://solimedia.net/product/hap-ac-lite-tower/ |Solimedia]] (for less than $90 with tax and shipping), or [[https://store.mikrotikcanada.ca/wireless-for-home-and-office/56-hap-ac-lite-tc.html|Mikrotic Canada]].
+Once flashed with the [[https://www.arednmesh.org/content/current-software|AREDN firmware]], the hAP will use the 5.8 GHz band as regular wifi for your computer to connect to, and the 2.4 GHz band can be used to mesh with other hAPs nearby.  Realistically, the hAP is not useful to make long distance links since it would require an external antenna.  But it is useful to [[./aredn/tunnelling|tunnel to others]] on the network via the internet to get started with the system.
+===== RF Links =====
+Once you're connected into the AREDN network over the internet, the next step is to add an RF link.  For that, a second device can be placed outside and connected back to the hAP via CAT5e.  For this, you can use:

 ===== Services =====
-Now that you're connected to the network, here are some services that are worth looking into:
+When connected to the AREDN network, individuals can run different services on individual servers like the Raspberry Pi.  Note that these services are only visible to a given AREDN network and are **not** accessible to the wider internet.  A few examples we have running right now are:
-  * VE7ODG's [[http://kt-arednsrv.local.mesh:8065 |Mattermost]] service for chat.  See [[https://groups.io/g/Mid-Island-AREDN-Mesh-Network/message/704 |here]] to sign up.  You can also use a phone app instead of the web interface as long as your phone is connected to the AREDN network.

-===== VE7TOP - VA7FI / Nanaimo - Sunshine Coast 5.8GHz P2P Connection =====
+===== Individual Setups =====
+  * [[./aredn/ve7lse|Devan (VE7LSE)]]
-On July 4, 2021, Chris (VE7TOP) and Patrick (VA7FI) made a successful connection on 5.860 GHz (Ch. 172) between Nanaimo (49.227263, -123.975836) and Roberts Creek (49.45465, -123.64199) on the Sunshine Coast (a distance of 35 km).

-{{  :howto:path.png  }}
-==== VA7FI's Setup ====
-Patrick installed a [[https://www.amazon.com/MikroTik-Wireless-Satellite-Antennas-RBLDF-5nD-US/dp/B072LQMD7N|Mikrotik LDF-5]] (the ''n'' model, <fc #ff0000>not</fc> the ''ac'' model) on a used TELUS satellite TV dish.
-  * The first task was to mount the LDF-5 to the dish roughly where the old receiver was.  Unfortunately, the arm and the LDF-5 mounting bracket were both a bit too short:
-{{:howto:aredn:tooshort.gif}}
-{{:howto:aredn:1original.png?400}}
-{{:howto:aredn:2tooshort.png?400}}
-  * So a second arm was bolted on top of the first to raise the LDF-5 and move it a bit further away:
-{{:howto:aredn:good.gif}}
-{{:howto:aredn:3good.png?400}}
-{{:howto:aredn:1original.png?400}}
-  * Initially, the dish was mounted on a post with a 45° angle, but after field testing it, it was found to be unnecessary and a vertical post will be used next time.

-  * Here's Patrick's setup and the view from the dish.  The red circle marks the spot where Chris is.  The [[https://elkantennas.com/product/dual-band-2m440l5-log-periodic-antenna/ |log periodic]] was for VHF communications between Chris and Patrick to perform the adjustments.

-  * Here are Patrick's settings:
-{{:howto:screenshot01.png?800|}}
-  * For the first test, Chris used a dish (FIXME: add details).  After adjusting the dish's directions and elevations, the best signal strength received by Patrick was above -60dBm (which is pretty impressive!) with an SNR of over 35dB:

-{{:howto:screenshot03.png?800|}}
-{{:howto:screenshot04.png?800|}}
-  * For the second test, Chris switched to a 120° sector antenna (FIXME: add details).  Here, the best signal strength received by Patrick was a bit above 80dBm with and SNR of about 17dB:

-{{:howto:screenshot06.png?800|}}
-{{:howto:screenshot07.png?800|}}
-These two tests show that it is possible to establish a connection between Nanaimo and the Sunshine Coast.  The 120° sector antenna might be pushing it a little bit, but a 60° would be enough to cover Gibsons a
