  1. Horn → 80Mhz channel > Cambium Force 300-16 → Noise floor -90: MCS9 = 1.3km. Horn → 80Mhz channel > Generic 802.11ac 16dbi → Noise floor -90: MCS9 = 420m. I can't believe it! Is this a calculation error, or does Cambium have any special superpowers because the power regulation must be the same, or something else -what?
  2. I think it would be nice if entering basic data could retrieve a list of requirements for customer antennas. Example: Frequency 5500 MHz, EIRP 30db, Noise floor -90, with CC60, for MCS9 CPE(SM) need to be: Channel width 40Mhz up to 300m - 13 dBi (dish) 450m 16 dBi 700m 19 dBi 900m 21 dBi 1.3km 24 dBi 1.4km 25 dBi Channel width 80Mhz 220m 13 dBi 350m 16 dBi 480m 19 dBi 600m 21 dBi 900m 24 dBi 1km 25 dBi
  3. As a devil, I only help you find answers to questions that WISP doesn't always ask, but tend to make assumptions (right or wrong) 😜.
  4. What about EIRP? Perhaps this calculator could be made fairer and help to calculate it instead of the user, ie the calculation changes dBm instead of EIRP. And how far does it make sense to have horns with a different gain if the whole end is leveled at the transmitter's TX power to comply with EIRP? In this sense, I can take any, 5 gain, 15 gain, everything in the end will be equal to for example 30-36 EIRP (possible MCS has any requirements) 30 = Gain-TXpower.
  5. When planning a well-balanced WISP network, you are definitely working with calculators, one of which will be an angle calculator. As you know, between AP / antennas, an 80Mhz frequency protection band is recommended, but in reality, no one can afford it, so variants with small side lobes (to reduce mutual interference) and even GPS synchronization are not considered in ABAB mode, but simply for adjacent devices. (life hak). And now look at some of the chaos created by the horns. Everything is out of the planned angle is a potential mutual interference problem. Probably this is what many people see when they look at such pictures.
  6. After what you wrote, I repeat that I do not really know. From the comments, I conclude that only few know exactly how it works. Many experiment, but I want to stick to academic knowledge at first and only then experiment (eg with Fresnel / Arago / Stand waves specific). I previously assumed that 4x4 MU-MIMO is a group (possible in a different horizontal plane) and in a group it works according to the lowest MCS (if someone in the group has only MCS2 then it will be the whole group), therefore, MU-MIMO is used only if if SU-MIMO can no longer be effective (the AP itself calculates which option will be more efficient). The Cambium forum has WISP, which with horns placed on their side, trying to realize 4x4 and MU-MIMO - https://community.cambiumnetworks.com/t/epmp-3000-ap-and-dual-horns/67660 How is it really there - 4x4 SU-MIMO with THB, 4x4 with horns in different directions, with Cambium Dual Horn (I heard you developed) and MU-MIMO with / without band? Can you tell us now without waiting for a webinar, video, etc.?
  7. Some WISPs with epmp3000 and two horns achieve MU-MIMO by pointing each horn to the other side (each horn only sees its own CPE group). If I'm not mistaken, it's called the split sector. You could make such a bracket, where it is possible to place 2 horns (symmetrical and asymmetrical) and where each can be adjusted to its side (both horizontally and vertically).
  8. I think BE is more for CPE, but the FTB is a mast for colocation. "The fish is blowing from the head." I also think that the criteria for awarding a Carrier class need to be reviewed (for example P2P SAF FreeMile Parabolic Frequency: 24.05 - 24.25 GHz, Gain: 45.1 dBi (high-band), Half power beamwidth: 1.0°, Cross-polar discrimination: 30dB, Front-to-back ratio: 70dB). Of course PTMP will have a different FTB ratio, but not 27 dB.
  9. Do you have any idea why with ePMP ™ 3000 Dual Horn MU-MIMO Antenna will be MU-MIMO, but with THB will not?
  10. Thanks & if possible, please show what it looks like in a real installation.
  11. I find it strange that antennas with such an FBI rating can be assigned a class carrier. The question of why this is important also seems strange, but perhaps it was meant differently. Smaller FBI, more noise. It probably doesn't affect that much if everyone on the mast is horn, but in the case of a hybrid, it makes more noise than if there were no horn. Noise is the biggest invisible enemy.
  12. I'll try to post pictures of what's inside. Hopefully everything will be exactly as you described (highest carrier class quality).
  13. Carrier Class horn HG3-CC-A60-V2 Front-to-Back Ratio only 27 dB Its inside is not ribbed? Does any RF horn have a ribbed inside or is it too expensive?
