That's right. I was referring to a place where all switches located. In other words, instead of getting switch on every floor, we're thinking about putting then in one room. If there is some hardware problems, it should be easily located. 

Totally agree with Omada SDN. That would make our life much easier.

Ground floor + 3 floors  

• 1st floor x 10 rooms  - 2 eap 225 - 1 POE switch to power the ap's of this floor  
• 2nd floor x 10 rooms - 2 eap 225 - 1 POE switch to power the ap's of this floor
• 3rd floor x 5 rooms  - 1 eap 225 - 1 POE switch to power the ap of this floor
• Ground floor has no AP's, it has coverage from the 1st floor AP with +60% strength !

Each POE switch has 8 ports total (4 poe ports + 4 gigabite ports) it is TL-SG1008P V3.1. The cable from each floor POE switch to AP's is not more than 10m and the cables are passed through drywall cealings which helps reduce cable length.

Are you able to get good reliable connection in last rooms ? (the one, that's far from AP)

Yes the connection is very good i keep checking in omada controller to see how it goes, maybe in rare cases for some devices using 5ghz the signal is not full, but im not sure if this has to do with 5ghz which is said it does not reach as far as the 2.4 or if has to do with the configuration i have set with the selected channels and channel width, first the basics to get it working then comes the fine tuning.

The EAP's are installed in position one towards the frontside and the other towards the backside of the building, the building length is approx 25 metres. 5 rooms are on one side and 5 rooms are on the opposite, 3rd floor is half the lengh the reason i have installed only 1 eap.

We're thinking about 1 room that has all switches and router and controllers and from this room all cables will connect to AP. This should make troubleshooting more easier for IT department ? Is that true ?  

Do you think it's good idea to put all switches in one place and lay the cables from one place, instead of separete them in each floor?

I thought of this option 1 room - all switches but speaking with our electrician and our engineer i was guided not to do this, so each floors cables are connected to each floors switch.

For maintance and troubleshooting be sure to buy managable switches, this will also help you setting limitations.

Of course what works for me might not work for you, each building is different and in our case from ground floor to the 3rd floor switch is one straight line and max 15 metres cable length. Be sure whatever you do always have spare ports on each floor for power,sfp or regular ports you never know you might need to expand and add a few EAPs, for this you will find out when your property is working and people are using your wifi.  

Every electrician and network engineer will confirm that such central wiring in a room is unfavorable.
Imagine you have to replace one 90m cable out of 70 cables b/c it failed in the switch's cable test. You will go crazy.

and imagine all the cable waste for this type of installation...

Good advise, thank you. This should also make putting cables easier and less complex.

Thank you for pointing this out. I understand this (finally). Each floor will have it's own PoE switch and have cables from the same floor. 

We're also adding 70 IP camera with remote view.

They're gonna be connected to PoE from switch. It will record and save information constantly to the NVR (network video recorder) that's inside hotel. 

70 cameras with Full HD should use around 280mb/s in total (4mb/s per camera). Since it's in our local network, it should not affect to the performance of the internet correct ? 

It will only affect when we're viewing video remotely using internet. In other words, 280mb/s that's traveling from IP cameras to NVR will not affect internet speed of the users at all. 

Is that correct statement ? 

@R1D2 


Awesome, thanks for confirmation.

@Boriy 

I fully endorse what R1D2 said.

If you are pumping a continuous stream of 280Mbps of traffic thru the SMB switches, you better have separate switches for the video traffic. And at the price point of Tp-link SMB, you can easily afford for a 4 star hotel. This will be like 0.0001% of cost of the overall hotel construction project :).

To give you an example, I have 8 cameras ( 4 MP) around my home and I have a super powerful destop that I sometimes also use. I display cameras on it and with all set to 4MP, max resolution, they produce about 7Mbps each, so with 50 to 60Mbps of total traffic coming into my PC (which has an Intel Gig NIC, 16GB of RAM and i7 (4 years old processor) and it becomes so sluggish that I really cannot do anything much on that PC. CPU is like 90%. If I stop the videos, then CPU goes down to like 2%.

So same thing happens with switches. SMB switches are designed to handle a bursty traffic. If you will push a constant large amount of traffic, they will cause overall slowdown. I will stringly recomemnd as did R1D2, that you add separate switches for Cameras and that is what I also do. I have few sites, where I have 30 to 50 IP cameras of 4 to 8 Mega Pixels and sending traffic thru the switches meant for private network or for Guets network has caused issues in the past, so split that traffic off and set up an isolated video network. And few sites I have Cisco catalyst, where this unified network works great, but you then spend many times over the TP-link SMB switches.

Very best
