 Please comment on the expected difference in achievable range using 20 dBm vs. 23 dBm output power. Any details, assumptions, questions, etc. would be appreciated. 
 Thanks, David</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 24 Feb 2020 14:30:41 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/58187/nrf9160-difference-in-achievable-lte-m-range-using-20-dbm-vs-23-dbm-output-power" /><item><title>RE: nRF9160: Difference in Achievable LTE-M Range Using 20 dBm vs. 23 dBm Output Power</title><link>https://devzone.nordicsemi.com/thread/236008?ContentTypeID=1</link><pubDate>Mon, 24 Feb 2020 14:30:41 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:66612259-f59a-49fa-b10b-1afc3856db9b</guid><dc:creator>Amanda Hsieh</dc:creator><description>&lt;p&gt;Hi,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;A rule of thumb is that 6 dB increase in link budget will give a doubling of range. This assumes quite ideal conditions such that a &amp;#39;free space model&amp;#39; can be used. Due to logarithmic relationships in this, a 3 dB increase does not give 1.5 times the range, but rather ~1.41 (square root of 2)&lt;/p&gt;
&lt;p&gt;Typically due to real-world effects, most accurate propagation models give a lower increase than this. Exactly how much is hard to say, and will likely depend on the environment near the respective customer.&lt;/p&gt;
