Even that did not help. 11b/g/n, dual-chain Wireless regulations Specific frequency range may be limited by country regulations Antenna gain 1. So MikroTik boards will use antenna-gain value to limit the power going into the antenna to 16-19dBm, thus capping the effective transmit power at the required 20-23dBm. The simple whip antenna commonly used in AP will have omnidirectional ring-shaped pattern, with gain over 2dBi. Antenna -gain of a "hAP ac Lite" is 2 dBi. In practice it mostly brings the TX/RX strength out of balance, with bad wifi performance as a consequence. passphrase="XXXXXX" . So while antenna gain doesn't help achieve higher radiated power<*> (due to country limitations), it does help to An important point, be aware that by using any other antenna than the one which came with the device you are breaking the conditions of the FCC certification of the device, even materially if the other antenna has a higher gain than the original one in some direction by more than the attenuation of the extension cable. wAP & Hap lite: Sensitivity: -71, Tx Power: 16 dbM 951Ui: Sensitivity: -78, Tx Power 23dBm 951 has a much better radio as AP, why? - it has 7dB Right. 4 wifi coverage in the hap ax2 is better? Top. 4GHz+5GHz+5. Yes, that's my understanding too. Since WifiWave2 drivers appeared it is like this, it is fixed to your country regulations. Hi, i'm running capsman on an RB4011 + 2 additional HAP AC3 + 1 Groove 2Ghz. AC3 has more antenna gain, but less radio transmit. Value for the internal antenna of the hAP ac2 is 3. Unanswered topics; Active topics; Search Hi, I bought hAP ac3 router and I want to decrease TX power a little because I have a small flat and I don't need so much 'radio smog'. Afaik signal "quality" is more or less proportional to (host_power * host_antenna_gain * receiver_antenna_gain) please correct me if I'm mistaken. 5 dBi: Antennas quantity : 2: Features. 8GHz+Dual+Band". Top. 1) Regular dipole antennae like on the ax3/ ac3 are omnidirectional like a donut ("round" in the XY plane but not spherical in X, Y, and Z axes). 4Ghz is stable, and The difference between different antenna designs are the “shape” of the RF field. Posts: 13502 Joined: Thu Mar 03, 2016 10:23 pm. 4 GHz: 3. 5 Any rumours about frequency-mode: manual-txpower or whatever it could be called in the future for experiments in wifi-qcom-ac package?

That EIRP limit is usually the case ! The hardware specs on the mikrotik website says: hap ax2: Antenna gain dBi for 2. Skinfaxi just joined Posts: 6 Joined: Wed Aug 02, 2023 7:08 am. This is nice for an outdoor (free field) signal level at the client if one is not limited by the regulatory domain EIRP level. The RB4011iGS+5HacQ2HnD-IN has four antennas because the 5Ghz interface supports up to 4 wireless chains. When using a high gain antenna your router has to reduce tx power to stay withing the legal boundaries, so the max signal strength you get is the same. 5 Any rumours about frequency-mode: manual-txpower or whatever it could be called in the future for experiments in wifi-qcom-ac package? Top The problem with unrestricted antenna gain settings is that it is possible to set it lower than actual value and the resulting EIRP is higher than allowed. 4 GHz chip model: IPQ-4018 : Wireless 2. But as indicated, the stronger signal received from the AP is not the way to evaluate the benefites of an antenna (gain) Down rated because Mikrotik did a terrible job on chain 2 antenna design, should have just made the board 1" longer and done 6 integrated, get rid of that and just use the integrated antenna's and gain 0 is stable and best range. Unlike what one could imagine from intuition a higher antenna gain is not necessarily correlated with "better" or "faster" connection. 11. Then another suggestion of setting antenna gain to 0 and no improvement again. Have a questions on wireless interfaces. 4 GHz chip model: IPQ-4019: Wireless 2. 4 wifi coverage) But higher antenna gain does help in Rx direction as well, which means that cAP ax will be able to capitalize this in Rx direction (compared to hAP ax2). 5 Any rumours about frequency-mode: manual-txpower or whatever it could be called in the future for experiments in wifi-qcom-ac package? Top While antenna pattern is not exactly circular in horizontal plane, the difference in antenna gain of slightly less than 5dB doesn't make it "directional" IMO. As long as that EIRP level is not your limiting factor, fiddling with 0,1,4,6 antenna gain will do nothing. This is my first MikroTik router . An antenna with more gain than an isotopic antenna only gain in certain directions and less gain in other directions. So by default, there are two causes for Tx power AC has a more powerful radio, but less antenna gain. On 2. I'm asking because hAP lite and mAP lite and maybe "normal" mAP seem to be the only 3 models powered via 5V USB thus they're the only 3 models that can be actually powered from powerbank or antenna-gain=0 -> antenna gain must be set to be legal for the country set. The reason is that to comply with the regulations, the maximum signal strength in the concentrated direction is defining the limit. Gain varies from 2dBi to 8 dBi. 4 GHz generation: Announcements; RouterOS; ↳ Beginner Basics; ↳ General; ↳ Forwarding Protocols; ↳ Wireless Networking; ↳ Scripting; ↳ Virtualization 8 Antenna gain parameter will act on the EIRP regulation, which limits "radio+antennagain power", to a value specified per frequency.
