<div dir="ltr"><div><div>The Bullet M5-HP has max 25dBm (aka ~300mW) output power while
the M2-HP has max 28dBm (aka ~600mW), at least according to UBNT
datasheet.<br><br>If the OP is referring to an M2, my advice would be to
not use such a high power radio in 2.4GHz if you're wanting wifi
clients to connect directly to it. Setting very high TX power can
saturate the receiver and drown out lower-power and/or distant clients.
Similarly, using a high-gain (aka highly directional) antenna greatly
limits the beam width over which clients could connect. Something like a
Nanostation M2 or Picostation M2 would be better suited for direct
2.4GHz client access.<br><br>Also, long-distance 2.4GHz links,
especially in urban areas, are barely viable these days. A bullet M5
would likely work much better for any high-power/long-distance use. <br><br></div>Either
way, OpenWRT should include some tx power limits per the country code
you set. For example, a Bullet M5 running AA r42647 with country code
US will give this in response to "iw phy0 info":<br><br> Frequencies:<br> * 5180 MHz [36] (17.0 dBm)<br> * 5200 MHz [40] (17.0 dBm)<br> * 5220 MHz [44] (17.0 dBm)<br> * 5240 MHz [48] (17.0 dBm)<br> * 5260 MHz [52] (23.0 dBm) (no IR, radar detection)<br> DFS state: usable (for 291882 sec)<br> * 5280 MHz [56] (23.0 dBm) (no IR, radar detection)<br> DFS state: usable (for 291882 sec)<br> * 5300 MHz [60] (23.0 dBm) (no IR, radar detection)<br> DFS state: usable (for 291882 sec)<br> * 5320 MHz [64] (23.0 dBm) (no IR, radar detection)<br> DFS state: usable (for 291882 sec)<br>...<br> * 5745 MHz [149] (30.0 dBm)<br> * 5765 MHz [153] (30.0 dBm)<br> * 5785 MHz [157] (30.0 dBm)<br> * 5805 MHz [161] (30.0 dBm)<br> * 5825 MHz [165] (30.0 dBm)<br><br></div>Also,
this page provides some handy antenna gain limits w/r/t to max
permitted EIRP in the ISM bands. For example, a 2.4GHz radio with 28dBm
output could only use an antenna with max 12dBi gain.<br><br><a href="http://www.wisp-router.com/page.php?11" target="_blank">http://www.wisp-router.com/page.php?11</a><br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Apr 16, 2015 at 5:41 AM, Adam Steele <span dir="ltr"><<a href="mailto:adamrobertsteele@gmail.com" target="_blank">adamrobertsteele@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">What frequency is your Bullet made for?

Hi All:<br>
<br>
What is the top omni DBI i can use with a 600 MW Ubiquiti bullet<br>
without running into regulatory issues in the US ?<br>
