Then where exactly am i going to connect all picos to? How many Servers would you suggest?

 

[kilos]

Then in the basement you get a Routerboard RB493AH or RB450 (enough so that each Ubiquity AP gets its own port. Bridge the ubiquity with the LAN port. If you don't worry to much about managing the network (and save money) you can always just get a 24 port switch, where all the APs run in to. Then the Switch connects to 1x RB450.

Your answer that was answered on Page 1
Roughly depends on your services that you are supplying ?
1) VoIP - running Asterisk PBX approx 2-4 Gb RAM
2) PPPoE server
3) IRC chat, plus other service ie DNS Some server can be combined
4) Firewall to Internet (Smoothwall/IPCop)

Thumbsuck

So with +- 45 X Pico Stations, i would use 2 X http://www.scoopdistribution.co.za/product_info.php?cPath=51_24&products_id=192 and the connect these to 1 X http://www.scoopdistribution.co.za/product_info.php?cPath=49_34&products_id=814 and have my 2 Servers connected directly to the RB?

That won't work.

An issue that we haven't really touched on properly is the cabling. The building is too big to use copper ethernet cables thoughout since they can only run for 100m. You would therefore need to lay a fiber optic backbone throughout the building with a (rather expensive) fiber switch in the basement. You would then also need a fiber and ethernet capable switch for each 2/3 floors. Fiber cabling is also not something that can be done DIY and you'd have to get professionals in to do it... more costs...

I agree that your budget is going to fall short.

This is a residence, not an mission critical enterprise. R50,000 can easily do it. And the ethernet is not 'n problem.

OH, and are they only going to allow BBS services ????

I work in an office with 11-15 people and our network was close to this budget just so that we can have the required bandwidth to do our work. Our previous network was so slow that sometimes I would go home to work on my own PC as it was more productive.

You get what you pay for.

 

[j@w]

His budget is R50,000. It can be done. So stop whining *OMG R50,000 is not enough*.

I've installed 7x MT hotspots in a residence with 180 units, 2-3 people per unit. Everyone connects via his/her notebook or TP-link device, NO CPE's. Nobody has ever complained about speed even with a DC Hub running. Running all the AP's into a single RB and a Thunderbird 1.1ghz for RADIUS.

I've ran PoE over 110meters, worked 100%. Bandwidth test between 2x RB's gave the same results as a 30cm cable.

And you can get something like homeplug. Plugs in the bassment & roof / lift shaft are normally on the same breaker as those of the units.

I've done this loads of times. If it is a narrow building with a lift it is quite easy.
Get a room on the bottom floor or underground near the lift.

Then just run a network cable in the lift shaft to every floor on which you want to put an AP.

Whoa, sorry what.

Does running random cables and junk in a lift shaft comply with the LEPC regulations??

Nevermind that, you're not even allowed in a lift shaft much less modifying one unless you're a registered engineer and are doing so in accordance with various permission.

What site did you do this on? Where do you work again?

 

[Syndyre]

LEPC?

 

[cda]

LEPC?

OHS - Lift Escalator and Passenger Conveyor regulations

3. (1) No person shall use or modify or permit the use or modification of any lift, escalator or passenger conveyor unless -

(a) such lift, escalator or passenger conveyor has been designed or constructed or modified in accordance with the relevant standard or specification pertaining to such lift, escalator or passenger conveyor and which is incorporated for this purpose in these regulations in terms of section 44 of the Act; and
(b) the requirements of The National Building Regulations, if applicable, have been complied with​

In 1995 my company used Mod Tap (now Molex), 3Com and Lambda products to wire the big blue building in this picture.

I am the local partner who signed off on their 15 year warranty. There's one year left on that warranty.

The average wall box in that bank cost more back then than what many WISPs budget for their total cabling cost for a wireless install today.

To date, I have not had to replace as much as a flylead.

Its not so much about the PoE working over that distance as it is the timing limitations of the Ethernet Spec. Ethernet is designed based on the delay of the pulse train traveling down the cable at near the speed of light. Unless you've rewritten some laws of physics that limitation still exists.

Besides... if you read the specs provided you would be able to work out that the longest cable run would be closer 200m (give or take a little for routing)

You want to backhual the APs with BPL??

The university has a 20Gbps backbone and you want to connect their res up with a sub 100Mbps network. Your solution might come in within budget but its definitely not future proof and the whole thing will have to be ripped up and replaced in about 2 years. R50k down the drain IMO.

Guess you've never seen a building with a +/- 40cm x 90cm shaft going next to the lifts.

Sigh, tell me whats your genius plan for R50k?

Funny enough, Stellenbosch University, has a combined total of 55mbps down & 35mbps up. This has to serve all the residences, labs, administration... and everything. 1gbe fibre links to each residence. Network ports per room is 10mbps or 10/100mbps depending on the res.

 

[portcullis]

Sorry to burst your bubble, but no I don't

I'm confused.

This this post you said that you are doing a site for a WUG.

Unifurm shows the records for hhwug here. Since we don't all have time to troll through this stuff, here's the registrant information.

1a. domain : hhwug.co.za
1b. action : N
2a. registrant : Jeremi-Ernst Avenant
2b. registrantpostaladdress: ** edited out **
2c. registrantstreetaddress: ** edited out **

Over here you tell us that you operate a WISP.

Guess what Uniforum tells us about wi9...

1a. domain : wi9.co.za
1b. action : U
2a. registrant : Jeremi-Ernst Avenant
2b. registrantpostaladdress: ** edited out **

So if you're not wi9 / with wi9 then which WISP do you operate?
