  2. Estimado mwireless, primero de todo hay que decir que las ULD380 ya no las hacemos, hemos mejorado los parametros de las antenas y ahora mismo estaremos ofreciendo las antenas ULD-TP-400 y ULD-TP-550. Nuestras medidas nos dicen, que pueden llegar hasta 80 km, pero de pende de varias condicioines. Si quiere respuesta mas concreta, diga noslo que necesita precisamente y trataremos de responder mas detalladamente.
  3. Yes, it is possible to overlap two or more sectors if they are transmitting on different frequency.
  4. it is possible to overlap two or more horn 30 ° without losing performance?
  5. Q&A del webinar de 11 de Enero 2017: Distancia maxima en km que cubre en una comunidad..? depende, cubren de 10m hasta mas de 20km Cual es el software para calcular el angulo antes de ser colocado en la torre? donde puede simular todos tipos de nuestras antenas SYMETRICAL HORN con varios tipos de radios.www.towercoverage.com- estamos advertiendo a los clientes usar la pagina Cuantos usuarios soporta este tipo de equipos (conexiones reales) normalmente WISP utilizan com 50 clientes en una antena. Existe alguna version del adaptador para los ubiquiti Nanostation M5 o M2 no, no tenemos adaptadores para los Nanostation M5 o M Que altura se colocan en una zona llana de arboles altos mi torre es de 70 mts. no hay una altura definida donde colocar las antenas, hay que probar cual es la altura mejor. Vi en las fotos que se puede ajustar azimuth y elevación, pero no veo si se puede ajustar el ángulo de las cadenas H/V. Se puede? no, el angulo de los H y V no es ajustable. Se comenta aqui el tema de que no se usan pigtails, sin embargo en la versión carrier class si lleva cable, merece la pena adquirir las carrier class? hay muchos clientes que han adquirido estas antenas en vez de otras y estan muy satisfechos. Te advierto el caso de estudio de WIFI.TEAM en nuestra pagina http://www.rfelab.com/topic/134-new-case-study-delivering-the-connectivity-in-shipyards/ esta aqui con comentarios tambien. Que porcentaje de eficiencia es la diferencia entre una antena sectorial de las mas comunes en el mercado comparadas con las antenas rf elements?? esto es un numero muy subjetivo, a todos los clientes ha mejorado la senal significativamente, no es muy exacto hablar sobre el porcentaje porque este numero difierre mucho. Para el área de cobertura en valles, hay que variar el tilt? todo depende que tipo de valle es, lo mejor es tratar de encontrar el mejor angulo do colocacion en la torre. Si tengo dos antenas simetricas en la misma altura y dice que no se interfiere entonces podria elegir el mismo canal? si el area que estas cubriendo es la misma, no va a funcionar. Si quieres utilizar el mismo canal con las dos antenas, depende de que distancia tienes entre las dos antenas y que areas cubren. Tenemos clientes que utilizan el FREQUENCY REUSE y les funciona. Si tienes un caso muy especial, te advierto escribir el caso a la pagina RFELAB.COM para poder analyzarlo. Por ejemplo, en este video el cliente tambien habla del FREQUENCY REUSE. Cuales son las distancias que pueden alcanzar las antenas UltraDish-TP-550? hasta 80km Usar esas antenas es como tener varios discos normales cubriendo la zona? Entonces el uso de frecuencias es mayor ? Qué sucede entonces ahí con la cantidad de la torre? como he dicho, las antenas no interfieren una a otra, tenemos clientes que tienen hasta 7 antenas de las mismas en la misma torre sin interferir. Cuando estan en venta las nuevas antenas? si se refiere a las antenas UltraHorn, etsas seran disponibles al fin de Q1 de 2017 50 clientes por antena, con cual Radio recomiendan? Rocket,AirFiber,Empm1000, ... lo reportan clientes con varios tipos de radios las de 90 grados que distancia maxima puede cubrir? la cobertura siempre depende de muchas cosas pero normalmente cubren unos 3-4 km existen covers "tapas" contra el viento? hay tapa que cubre lo de adentro de la antena, no hay otras tapas que diferencia hay entre: TwistPort-Shielded-Adaptor-V2-for-RouterBoard y no V2 en la frequencia la version 2 tiene el rango mayor de la version 1 Existen covers "tapas" contra el viento? para las UltraDish-TP-380 y 550 no
  6. Good! With your excellent clarifications I now have a more detailed picture of how its done and yes indeed, as you say, there are more roads leading to Rome.....
  7. There is no only way to solve a problem. We tested many ways, many equipment... and then we solve the deployment. 1. Yes XL CARRIERCLASS is used as AP and is the best solution, the signal is OUTSIDE the decks and send the signal inside. All de ceiling or indoor solution requires to put one cord throw the sealed doors. With our solution all the AP are outside and no need to pass cords across the sealed doors. The RF signal with de XL CARRIERCLASS is EXCELENT and is capable to reach 2 decks with one AP. 2. Wrong, the ships moves, not a long distance 50-100m, this is the reason to use the horns with 30º. Horns are capable to reach the signal in that case without need of repositioning or move the PtP horn. 3. Only one netmetal in PtP, the another are Mikrotik inside XL CARRIERCLASS and all the solution is conected with a POE switch, only 1 in the ship. 4. All equipment is in good state, you need to protect and not damage the bolts in the second tight.... use the correct tools and the needed force. 5. All the solution is linked from outside the indoors, this is the best solution to avoid sealed doors, distribution inside, meters of cords... We can mount and umount all the solution in less than 1 hour. The other providers and solutions requires to deploy too much cords, ceilings, meters of cords... TIME IS MONEY, and de RF singnal is below our solution. 6. Ships has 110v or 220v. Use the correct conversor to our standart in spain who is 220v All your alternatives can be possible, test it and improve it, but we are proud to say we make a working one....
  8. Estimado mwirelesspr, el webinar no fue grabado sin embargo el siguiente lo puedes ver en vivo el primer de Febrero a la misma hora. Para registrarte utiliza la pagina https://www.rfelements.com/support/webinars. Gracias.
  9. Saludos, cuando estara disponible el ultimo webinar que dio? o donde esta disponible para repasarlo; fue muy bueno!

  11. Maybe an add on for the ignitenet scope (http://www.ignitenet.com/products/metrolinq-scope/). Many operators start to user their 60Ghz product line more and more too. A clip that sits around the smallest ring of any horn (they are all the same dia?) where the scope then gets attached too. RF Elemenents is great in making such add-on devices for 3rd party products.... The target cross in the scope should be pointed towards a landmark that you'd calculated in Google Earth first. (Take a copy of the picture with ya!) All that is needed is that the scope indeed is H+V parallel with the centre of the horn...
  12. I've been reading the case study and have some questions: 1. Why use the XL CARRIER CLASS 2.4 GHz on each deck? Is it used as AP antenna for client's devices to connect? This is a directional antenna, that looks to me a bad choice in any building like environment. Especial since its a shielded type of antenna. A better choice to me would have been a ceiling fit omni directional or something like StationBox InSpot housing. A typical ship superstructure is internally also divided by metal bulkheads (= walls) that are highly reflective and non penetrable. Hence in my opinion a multi path multy antenna AP, preferably 4x4 with beam forming would be a much better choice. The signals can then enter cabins and other spaces through doors etc. 2. Although on the outside the horns are used to pickup the signal from distant AP I hope these ships are not regularly moved to another part of the quay. If so you need to re-align the ship unit each time again. But this is not a common practise I know (the moving of the ship). 3. Since it seems this is a temporarily situation for ships occasionally berthing at the dock it means the horns are to be moved and used again on the next ship each time again? I happen to have to move a horn once after two months and at the second attempt to tighten the screws one of the bolts 'locked' by the destruction of the tread. The alu bolts already corroded. I had to replace it.... This is in a very arid hot climate miles away from any salty sea air...... The guy using these horns in this environment better greases the bolts otherwise he need regular replacements... (The materials of the bolts are a weak point in the furthermore splendid design! :-) ) 4. How is the network distributed from the CPE-Netmetal to the netmetals on each deck? He must be using a switch or router with many Ethernet ports. One for each device? 5. The cables, do they run over the decks? On the bulkheads? Walls? How to enter the accommodation superstructure? Usually a ship's superstructure is made watertight, so unless doors/window are left open cables have no simple way to enter. To run and fit and later remove the cables seem a lot of work to me each time again. And then most cables don't like to be moved a lot. Or they tend to be a hazard if loose and trip people. I know, I'll tell you! 6. How is the power supply of all the devices arranged? You need a set of 110/220V and maybe even other type of voltage power supplies that also need to fit the different socket types that are to be found on ships... Ships have as many standards as there are on the world and probably even more..... I have one suggestion that might proof to be workable; Have the CPE unit fit on the bow mast of the ship. Also fit a second directional (Just enough to cover the whole superstructure from there.) Another 30 degree horn could be perfect) These units in the mast are well out of the path of most workers and can be fit with short cables and one power supply only. No more risks of somebody tripping over a loose cable or braking the cable and only one socket needed to fit ship's (or yard's) power supply. Then on each deck, behind a cabin's- or recreation room's- or the brige's- window place an indoor dualband (5Ghz for CPE and 2,4Ghz for AP) device. If this device is placed direct behind the window it will pickup the outdoor 5Ghz signal and on the interior now distribute a 2,4Ghz signal in that cabin/bridge/deck (if there are not metal bulkheads blocking it). No need to run cable to each indoor AP. And most rooms/spaces have wall sockets available so it won't be hard to find one for the 'window-'unit. And if the signal from one such device is not penetrating the whole deck, just fit another one behind another window..... To me this looks a much cheaper, more manageable solution also less vulnerable (no loose cables = security item!) to incidents or accidents. No extra router needed (one of the Netmetals in the fore mast can do all the client's authentication, limiting and routing etc.) since all deck AP's are wireless connected to the one AP. The indoor CPE-AP units can be much cheaper too. So cheap that you can leave them as a bonus to the crew! (And where to hang the big XL's? A rb hAP-ac with its 2x triple chain radios is a perfect high capacity unit that presents the deck with some Ethernet ports too!) And we don't have to use any cables! Regarding the 5Ghz signal penetrating the glass of the superstructure; When the outdoor AP is in the foremast, it will hit the glass of the superstructure under an almost 90 degree angle. I think the signal passes that without too many losses. If the AP would be located at the side (on the quay for instance! Even less work!) then I am not sure. It could be that when the signals hits the (thick!) window glass under a smaller then 45 degree angle it might get reflected.. The bottom line is I can pick up outdoor signals inside my house with a device better behind a window then behind a wall and in fact years ago we've had 5Ghz ubnt nanostations with a special vacuum nap device to fit it on the inside of the window picking signals from an AP a kilometre away..... it worked fine. I've been working on ships 25 years of my life and now for 15 years am a wireless network operator with RF as my main field of interest. Probably from the days as radio licensed officer with basic background educations on the behaviour of radio wave propagation..... If my suggestions are appreciated by the operator he can send me a pm rudy@marucom.es if he'd like to discuss any other aspects. I even have an idea to avoid the need of the foremast CPE-AP setup to save even more costs and hassle. Nice article though!
  13. That is right just in case that the antenna is transmitting directly on the other AP. Since horn antennas do not have any side lobes, the other AP has to be in the main lobe. As you can see, this is not happening here, APs are not in the main lobe of the antennas, the APs are shifted and only streams are crossed. The proof that such an installation works is very positive feedback from customer who install it:
  14. I wouldn't agree. At such short range signals from one will penetrate heavy in the radio circuits of the other. This is noise and at a very high level. Unless the radio has really good filters or out of working channel frequency rejection I think it is not good. I would never fit them like that...
  15. Thanks for feedback. We will definitely look into this in order to provide you with an easy tool that will help you to aim our horn antennas.
  16. A TwistPort spotting scope would truly be awesome to have, especially once the UltraHorns hit.
  17. Read our newest case study from Wifi.team. Find out how our Symmetrical Horns Carrier Class help them to deliver connectivity to vessels in very demanding conditions of Navatia Shipyards.
  18. sabra los alcances de las ultradish? 380 y la 550? punto a punto?
  19. Yes, you got it right. At 21 degree - it is defined symmetrically so it means 10.5° from the center on both sides - the signal will be 3dB less than the maximum so the antenna has 15.5dBi gain there. At 30° (15° from the center on both sides) the signal is 6dB weaker comparing to the maximum so the gain of the antenna is 12.5dBi. The maximum gain of 18.5dBi is always defined at 0°. At 5° the gain of the antenna is 17.7dBi and at 10° the antenna has 17.2dBi gain.
  20. It does not matter if the streams are crossed when you are using them on different frequencies.
  21. Can you explain the gain of the 30 degree horn at the 3dbi and 6dbi sides? I have 3 of the 30 degree horns and I'm wondering if I should go to the 40 degree when doing 360 degree coverage. I guess what I want to know, are we getting 18dbi at the edge of the 20deg mark or 15dbi? and would the 30 degree edge only be 12dbi? If this is true then what is the 5 and 10 degree points? Is the 18dbi in the center at only 4 degrees?
  22. Take the cover off the front and the radio off the back. You can look through the port to gauge the target zone. You can proof in google earth when planning the site. Twist port alignment scope/tool. The tool could be your cell phone camera in a twist port that holds the phones camera in the right place (or a GoPro). And an app for PC or other device that allows you to look at the target coverage area in google earth to make a target picture. Then when you are on the tower with the twist port alignment tool it will show you the google earth picture as an overlay or simple cross hair or ring. The app could have a selection to choose the horn you are using. Or maybe a simple tube with an eyepiece, it could slide in and out to the correct field of view to match the horn. I think a clip on spotting scope would be easier to manage on the tower. Maybe clipping to the back/smallest ring where the set screws are. Or even something that clips to the front. Just my thoughts, Sorry for rambling.
  23. Shouldn't those horns locations be switched? They seem to be pointing into each others stream. And I think we all learned by watching Ghostbusters, "Don't cross the streams".
  24. MimCom is making good point on how to approach as in general. It works very well in hundreds of installations. The wider beam / higher antenna gain / more side lobes you go, the more issues you cause to yourself and to others. If you can share site info with us, we can advise you what to do. Otherwise it will be generic discussion without much value for you at the end. If you prefer to take it offline, shoot PM to Mike or me.
  25. jober, do have a problem with the ring? Usually it does not happen often, just in very few cases. However if you follow a standard RMA process - through your distributor - we will try to do our best to help you.
  26. jonwamg, Were you able to get a replacement ring? If replacement parts are not available we all need to factor that into our decision when buying these. (As with any product)
  27. Well, with the global warming this issue melts away! lol. You are right, but to me its not a single problem. Sub zero temps would hit the papers here where I live (East Spain)
