Hi All

I have been charged with investigating the possibility of creating a residential gated community network in my apartment block.

The apartment block is fairly small with only 18 units. These units are laid out over 3 floors, each floor with 6 units. There are already service hatcehs that are currently being used to run piping for water, gas and some DSTV cabling, 3 service hatches in total, which each one servicing 2 apartments per floor. This would be the logical spot that we would run the cabling. There is a body corporate owned room on the ground floor where the switching equipment would be housed. Maximum distance between the room and the furthest apartment is +- 40m.

I have a few questions about this though, as I would like to minimise costs wherever possible and not go out to a specailist company if I can avoid it.

What network technology would be best suited for us to make this work? I have thought that CAT-5e would be fine, but would this be suitable for triple play offerings in the future?

If I use ethernet, I was thinking of just getting a 24 port gigabit switch and mount this in the server room, and then running the cat 5e to each apartment. Would this be adequate?

Each apartment will only have 1 termination of the cat-5e. If they wanted to extend this, would it be as easy as connecting a 4-port switch's gateway port for example to the ethernet jack?

What options are there to provide internet access to each individual considering that there is now a centralised network switch. Would it be a process of connecting a router to the switch, and then having an SP provide the router connection to their networks? Who does this at the moment? Preferably I would like to have 1 uncapped line capable of providing decent speeds to all users, thereby having 1 fixed cost, rather than each resident settling their own costs with the service provider. Any help here would be appreciated.

Currently the view is to only provide internet access to each unit. However, I want to ensure that if we wanted to add other services in the future that this network configuration would be adequate. Services on the cards are:
  • DSTV
  • VOIP, Access Control and intercoms
  • CCTV
Particularly, what kind of equipment would we need for each of these extra services, especially DSTV, as I have no clue of how this would replace an LNB connection. Would Cat-5E and a gigabit switch be adequate?

Any suggestions or help would be appreciated.

Ideal for sure.

Perfect, max distance of 100m, so well within the range

I have thought that CAT-5e would be fine, but would this be suitable for triple play offerings in the future?
Yes, most definitely

Yes, most definitely

Yes, they would simply plug their single ethernet jack into their own switch and distribute as they wish, whether it be wireless or cabled.

Can be as simple as an 4Mbps uncapped ADSL terminating in the lower floor switch room, through to leased line type offerings from the telco's - I'd start with the ADSL.

Bandwidth on a Gigabit network won't be a problem for any of the services you mentioned. DSTV however is another story, best for now is the leave the LNB config as is.
 
Your two biggest problems are not listed here. How do you limit a user from not raping the bandwidth resulting in everyone else suffering, and getting your IP blacklisted because dumb users don't know what antivirus is. It becomes an admin nightmare quite quickly. There are many opensource choices out there, I would suggest looking into a transparent proxy that does bandwidth limiting and also have each user sign a fair use agreement on what protection they are using.

Good luck!
 
All I can really say is I wouldn't go Cat-5: Feel it's just not worth cabling anything less than Cat6 at the moment. Not a major difference, but I think you will get a lot more room for growth if you take the plunge in the beginning already.
