What is the best way to place sockets for telephone and local network in the office?

Question

Computer networks

An office is under construction. The case is coming to the finish, you need to decide with the SCS gasket.
The structure is basically Open Space, except for the management offices. Almost all tables are along the walls. Almost all computers are either NetTops or will be transferred to small-sized cases. Computers will not stand on the floor.
Approximately 40 workplaces, 2 floors.
Near each workplace, 3 computer sockets (for a computer, IP phone, printer / reserve) and a telephone socket are planned. With them in a row - power sockets.
Actually questions:
1. At what height it is better to place sockets?
a) Low, about 30 cm from the floor (like European standard, everyone does it that way).
b) Just below the tabletop (the eyes are not callous, the wires do not hang on the floor)
c) Slightly above the tabletop (visible, accessible, convenient for servicing and connecting chargers, laptops, etc.)
d) Other options.
2. What is the best way to lay SCS around the office?
e) In the cable channel (a thick box sticks out around the perimeter of all Open Spaces, not aesthetically pleasing, but very convenient when rearranging furniture and transferring personnel, for connecting additional devices and installing additional sockets
) more aesthetically pleasing, nothing sticks out, but connecting a new workplace or moving furniture is a whole problem
)
h) Make hatches in the floor with power and information sockets (I used to make "racks" on the floor with sockets (they missed the layout by almost a meter, the racks were in the middle of the aisle ...), now I bought a hatch for testing)
and) Somehow
Please share the experience of those who did or used SCS in the office.

Answer 1

1) Make a cable channel above the table (~ 10cm). Take the installation cable channel with a separator (low current in one half, power in the other). In the cable channel you mount power (3 pcs., Better 4!) And computer sockets (2 pcs.).
2) For printers sockets 2x2 (power / rj-45)
3) Very carefully (very, very) calculate the installation of power sockets, they can hardly be moved! The power cable must be without twists and cuts and intermediate connections and have a minimum margin! (any electrician will tell you that). The wire must have the correct cross section ! The only possible type of installation is through the sockets.
4) All low voltage wires should be wrapped around the patch panel in the distribution/server room.
5) If desired (in 2-3 places), special power sockets are made, powered from the second machine! This is for teapots / vacuum cleaners, the section is appropriate, they are highlighted in color (usually red)!
6) Installation cable channel - any company, even Legrand, even DKM, even Efapel, from the same company and all other accessories. I don’t see a big difference between manufacturers, all three are good!
And of course you can lower the cables from the false ceiling. But absolutely all cables must be removed into the corrugation where it is laid along the ceiling. Power, so generally desirable in metal. You don't need to do this in a cable channel! It is not necessary due to the fact that our cable channel is motionless, and on the ceiling we have a free-lying cable and there is a possibility that it can be hurt and damaged (the probability, alas, is not small, as it turns out!).
If you make a laying under a false ceiling, then it is much better not just to put the cable on the ceiling, but to use cable trays (a piece of mesh with a side) around the perimeter, then the corrugation is not needed. But you need either two trays (low current, power) or power in the corrugation (on one tray) or a tray with a separator. In this case, you can lower it with a simple box with sockets at the end, or with installation racks.
But how gimmicky then fuss under the false ceiling ...
