Also check if your jurisdiction will require using plenum rated cables indoors. Generally is the case here in North America and believe in Europe, for commercial / business use case

hmm.....From what I heard and what IT consultants said about it, there is literally no regulations for this yet. Remember we're ranked (in speed) #181 out of 207 countries. Since it's not very IT country, there is little or no regulations especially in IT field. Probably we can use any type that works for us and we should be good.



Looks like you are not leaving anything for the consultant as he / she should know all this and much more and you are probably leaving only the configuration part for that person to do. Anyway, you have now lots of knowledge to successfully implement the solution.

I learned very important things here, but I believe there is lots to learn, and IT consultant will be needed, but thanks for compliments :)

These are not IT regulations, but are health and safety and electrical code regulations for any type of cabling you will run. Plenum rated in our region is not limited to the data cabling.

Now it depends, but given you are talking about a 4 star rated hotel (irrespective of the country, these are at least relative ratings within the country), and when all this cabling and data / internet equipment will be fraction of the cost of the overall building, I will not recommend to try to save little money here. Please do the best and remember cabling will stay with the building and will probably last for 20 plus years easily. So if this all amounts to saving 0.0001% of the overall building cost, why will not use the recommended CMP / plenum rated cable. R1D2 also advised to use shielded cable and connectors, so as long as you can find a shielded Plenum cable, I will go for that. My understanding is that STP outdoors rated is generally not plenum, but there are STP indoors that is plenum rated. So please follow excellent recommendations made by R1D2 as well as few made by me and in the grand scheme of things, it will not cost you anymore.

This thread is becoming a very important design guidelines for anyone new to the field. R1D2, you may want to request the moderator to sticky this for others to use.

This is our planned to use Cat 6 shielded cable:



and if we put it in RJ45 it will be like that: (cat 5,5e and 6 have the same size)



Our EAP-225 Wall need RJ45 connecter in back in order to operate, but Cat 6 shielded can be field in RJ45.

In our case, we can use it since both Cat 5E and 6 have the same size and can fit into EAP-225



Is that correct ? Sorry if I miss something again

@R1D2 

Looks like CAT7 is a requirement in europe, but it is too expensive here in North America. Our requirements is to use CMP (Plenum) and CMR (riser) cables within building and STP gel filled outdoors.

@dpsguard 

Absolutely agree.

IT networking in hotel, it's one of the things, that we're trying to do very good. Before starting this post, I've been told to buy 2 AP for each coridor (15 rooms total) and it should be enough for entire floor. 
But now we decided to have EAP-225 Wall in each room, so each client can have very good connection, regardless of their position (close or far from AP). Also TV will be coonected using Ethernet from AP, so they'll not make wi-fi so busy. So no worries, we'll do our best to have best possible networking experience here.
