+setOutputPower
+~~~~~~~~~~~~~~
+
+.. code:: cpp
+
+    void WiFi.setOutputPower(float dBm)
+
+Sets the max transmit power, in dBm. Values range from 0 to 20.5 [dBm] inclusive, and should be multiples of 0.25.
+This is essentially a thin wrapper around the SDK's system_phy_set_max_tpw() api call.
+
+If wifi connection issues are encountered due to signal noise, one thing to try is to reduce the Tx power.
+This has been found effective in cases where STA mode is in use with 802.11n phy (default). Reducing to
+e.g.: 17.5dBm or slightly lower can reduce noise and improve connectivity, although max range will also be reduced.
+
+setPhyMode
+~~~~~~~~~~
+
+.. code:: cpp
+
+    bool  setPhyMode (WiFiPhyMode_t mode)
+
+Sets the WiFi radio phy mode. Argument is an enum of type WiFiPhyMode_t, valid values are:
+-  ``WIFI_PHY_MODE_11B``: 802.11b mode
+-  ``WIFI_PHY_MODE_11G``: 802.11g mode
+-  ``WIFI_PHY_MODE_11N``: 802.11n mode
+
+Per the NONOS SDK API Reference document, the AP mode only supports b/g, see notes in section on wifi_set_phy_mode() api.
+Returns true success, false otherwise.
+
+Some experiments have shown that 802.11b mode has longest LOS range, while 802.11n mode has longest indoor range.
+
+It has been observed that some wifi routers may degrade from 802.11n to g/b if an ESP8266 in g/b phy mode connects to them. That 
+means that the entire wifi connectivity of all devices are impacted.
