max transmit power on 5.8Ghz?

[D-Boy]

Hi, whats the maximum transmit power on the 5.8Ghz and is it also unlicensed like 2.4Ghz, because I want to link up 2 offices, but the big question is whats the max transmit power on that frequency? I don't have a license

What distance.
Line of sight.
What bandwith.
What antenna do you plan to use.
Only 2.4 is open and might be dirty.

Line of Sight? Distance?

Yes, 5.8 is also unlicensed, but I suppose only up to a certain power level.

Look at Mikrotik & Ubiquity.

More power is not always better.

2.4Ghz is messedup, 4 blocks away from me someone have a wireless cctv analogue "link" using 3W or more just to penetrate a couple of houses in the way, killing ch1,2,3,4,5 on 2.4Ghz and I can even pick up their feed with a small receiver with a 1dB antenna from my old 2.4Ghz cctv cam set

line of sight, yes, distance, around 1km max, I've been checking out those Ubiquity nanostations but it doesn't really look that weatherproof to me tho

.. ok so 2.4Ghz is 100mW max and 5.8Ghz.. is it also 100mW or 250mW ? this is the only thing that I'm not sure of now

I have one of these and its quite strong and "legal"

1Km is not much so you don't have to worry about max transmit power.

Mikrotik is very nice and advanced but if you want quicker and easier click and connect, go Ubiquity.

soooo true!

lol... I just want to know the max power ratting on 5.8Ghz for general knowledge

 

[UnUnOctium]

10 dBm for SRDs, 20 dBm for Wi-Fi compliant devices. Depends on application and modulation schemes. You have to ask ICASA if you want to be sure.

ohhh... thats going to be a mission :*(

I have 5725 - 5850 @ 4W eirp PtP & 200W PtP as per this document - http://www.ellipsis.co.za/new/wp-content/uploads/2011/02/GG-32769.5.8GHz.Regs_.pdf. Unfortunately they seemed to have got it wrong in the 2010 Radio Regulations.

lol yea hectic!!
