One more 'just to be sure' : the subnet mask is correct ? Otherwise try to get a PCAP from traffic within the VLAN (or from of the port of the non-functioning APs) and see what happens with DHCP requests and offers.

Hi, just to be sure: have you checked the size of the DHCP scope ? (been there, done that, smacked my face...) Grtz

There are a few scenarios where you want to avoid DFS-channels (VoWLAN designs for example), not disable them. In that case you might want to avoid the Cisco 1500-series because these are DFS-only and you might want to ruggedize an indoor AP (E.g. AP in an IP65 enclosure with heating). The fact is that outdoor APs have nice ruggedized features out of the box which make them interesting for harsh indoor enviroments (cold/heat/humidity). The lack of non-DFS-channel support on the 1500-series got me wondering if the Meraki outdoor APs also followed this 'design'.

You're right about the regulations but I wondered if the outdoor APs are limited like the outdoor APs from Cisco (1500-series). These cannot use the UNII-1 and 2 bands which is a bit odd considering the fact the indoor AP can be used on every allowed frequency and you can use them outdoor with an enclosure (you would have to disable the lower UNII bands). The reason I'm asking this is that the outdoor AP's are suitable for indiir use where the enviroment is harsh (heat/cold/etc.) but that would automatically mean you would have to use DFS-channels. So for a VoWLAN design these are not the first choice, then I'd rather use an external antenna on an indoor AP in an enclosure.

Hi all, Maybe I have overlooked some documentation but can anyone tell me if the MR74/MR84 access points use DFS--channles only (ch. 100+) in the ETSI-domain (Europe)? I know that the Cisco outdoor APs are limited to DFS-channels. With kind regards, Marcel.

I've considered the MR84 with a stadium antenna for a wharehouse because this antenna has a narrow beam ideal for getting the signal between the racks but we went for the MR42E with the narrow patch antenna fot the initial design. Things might change, have to get feedback about what the enviroment will be in the wharehouse. Acceltext has a great range of products. The AP mount looks great.

There are two 4-lead antennas for the MR42E/53E and for the MR84 you can use the Stadium antenna or a third party antenna. The 2 antenna setup is a bit odd and I wonder why they designed them the way they did (considering the fact that Cisco Enterprise has enough templates for antennas to use).

a few weeks ago I opened a thread about the MR84 and how to use the antennas https://community.meraki.com/t5/Wireless-LAN/MR84-and-dual-band-antennas-vs-MR74/m-p/54414 Take a look maybe the discussion has some useful information for you.

I ran into the same issue concerning documentation. The distance between the antenna’s should be at least one wave length. Have no idea what the maximum distance is but keep in mind to far apart will increase the coverage angle and that might affect your intended coverage.

Hello Brad, as they say in the wireless community 'it depends'. What might work in your warehouse might suck in the other. If you have racks which are not filled to the brim or the materials stored are 'wireless friendly' (when looking at attenuation) you can have great coverage with only a few access points. Things get tricky with metal parts or with food. Omnidirectional antennas can be great in offices but can completely screw up your wifi performance in a warehouse. So it really depends... Here's a great video about Warehouse WIFI: https://www.wlanpros.com/resources/warehouse-wi-fi-francois-verges-glenn-cate-wlpc-phoenix-2018/ and this is a great blog post on why chosing a different antenna can make a big impact: https://blog.theitrebel.com/2018/08/27/warehouse-wireless-design-ideas/ With kind regards, Marcel Tempelman.

Hello Dave, thank you for your extensive reply. You answered a lot of my questions I had. I hope we win the deal. I look forward doing a large scale Meraki wireless infrastructure . Until now it has been Cisco Enterprise only. With th kind regards, Marcel Tempelman.

Hello Dave, thank you for your reply. The APs will be placed in a warehouse and it depends on the enviroment if you can use indoor access points. That's why we looked at the MR74/84 in the first. The MR84 is a bit strange in my opinion: - it is a top level access point (in my opinion) with only 1 radio per frequency (compared to the Cisco 2800/3800) - there is no Meraki dual band (sector) antenna with 4 leads - the construction with 2 sector antennas is quite big and i'd prefer a single antenna in front of the AP. Having 2 anntennas next to each other (vertical or horizontal) will increase the coverage angle. This is why I wanted to know if the AP works with 1 antenna and what the impact would be. The 4x4:4 functionality is nice but not necessary for aisles with one or two handscanners.(there is also no documentation on the mounting of both antennas; I asume they need to be mounted at least 5" apart). It seems the MR84 is designed for omnidirectionals in mind not with directional antennas. For now the MR42E is our best option (unless we need to adapt to an harsher enviroment). with kind regards, Marcel Tempelman.

Hello all, I got an answer from Meraki : The MR84 can work with one dual band antenna. They did not specify the difference between using 1 vs 2 antennas. When using 1 antenna you need to terminate the unused antenna ports with RF Load terminators (https://www.pasternack.com/50-ohm-rf-load-terminations-category.aspx). with kind regards, Marcel Tempelman.

Hello Brecht, Thank you for your reply. What you describe is my assumption also : decreased functionality when only one antenna is in use. We were certainly not planning using the anntennas is different directions because in that case the MR84 should have had an extra radio like the Cisco 3800. Hopefully someone will update the documents so that we don't have to assume things. This morning I was discussing the situation with my colleague and I tested some antenna patterns in Ekahau and the MR42E with the 3F antenna (narrow patch) is probably a better option. The 'Universal AP and Antenna Articulating Mount' from Acceltex makes the installation also a bit easier. If the (exptected) warehouse enviroment is friendly for this type of access point than we will go the MR42E way. Nonetheless I would like to have an official Meraki statement about the MR84 antennas. With kind regards, Marcel Tempelman.

Hello all, We're looking into a warehouse wireless solution based on Meraki access points for one of our customers. The MR74 and MR84 are candidate access points. What bugs me a bit is the lack of proper documentation on how to combine access points and antennas. For example nowhwere in the documentation of the MR84 can you find if you can use the AP with one or two antennas and if you are able to use it with one, what the benefit would be if you'd use two. As far as I know the MR84 can be used with one antenna based on this 'if' statement in the installation guide: Reminder: Both 2.4 GHz and 5 GHz client serving radios are diplexed onto each antenna port, so if using multiple antennas it is best practice to aim all in the same coverage area. Using 2 antennas in this case makes installation extra complex because you need to align them in a proper way and the construction needed for mounting the aps will be bigger. I'd say the stadium antenna or a 3rd party dual band antenna with 4 leads is a better fit for this access point. The MR74 can use single band and dual band antennas (will be reduced to singe band antenne on the MR74). So my question is; what is best suited for a warehouse setup? The MR74 of a MR84 ? And if it's the MR84 what's the best practice concerning antennas (1 or 2) ? Thanks in advance, With kind regards, Marcel Tempelman.
