+	# Mid Testing
+
+	# Mid Testing
+
+	Sydney is currently split into two distinct radio settings.
+
+	* Narrow: This is primarily used in the Northeast Sydney and Newcastle
+	* Wide: This is used in Western Sydney, Southwest Sydney, and the Blue Mountains.
+
+	There is a new setting that is being tested by several people dubbed "Mid".
+
+	\| Setting \| Mid \|
+	\| ---------------- \| ------- \|
+	\| Frequency (MHz) \| 915.075 \|
+	\| Bandwidth (kHz) \| 125.0 \|
+	\| Spreading Factor \| 9 \|
+	\| Coding Rate \| 5 \|
+
+	Problems that are trying to be solved:
+
+	1. Sit at the bottom of the AU ISM Band and avoid conflicts with [LoRaWAN](https://www.thethingsnetwork.org/country/australia/) gear (which starts at 915.200 MHz).
+	2. More speed benefits closer to Narrow; by increasing the Bandwidth
+	3. Distance benefits of Wide; Western Sydney has a sparse node distribution with long distance links.
+	4. Find common settings that the whole Sydney Mesh can agree upon to resolve the Wide/Narrow split.
+
+	## Testing
+
+	If you want to temporarily test these settings on a router:
+
+	`tempradio 915.075,125,9,5,120`
+
+	This changes a repeater to the mid settings for 120 mins. It will revert to the previously configured settings after 2 hours or if the repeater is rebooted.
