I have been set the following assignment:
-----------------------------------------------------------------------------------------------------------------------------------------------
The Head Office of the Smith Fabric Company is located in a four-story building. Each floor consists of an open plan office measuring 200mx200m. 24 staff are located on each floor who are supported by stand-alone PCs, which desperately need upgrading. The Company is planning to renew all the PCs and to set up a LAN to link them together. It is also the Company's intention to connect the LAN to the Internet. To gain access to the Internet, the Company has just signed a contract with an Internet Service Provider and has received a Class C IP address. It is the Company's intention to run a web site at this site to publicise the Company's products to the outside world.
The Managing Director has been advised to use wireless network for the new LAN for its flexibility. However, security is a major concern of the managing director and the network should include appropriate security mechanisms.
As a consultant, you are required to:
1. Design a wireless network for the Company, incorporating any new devices required.
2. Allocate appropriate IP addresses to the relevant devices.
3. Draw a diagram for the network.
4. Provide cost analysis for the devices required.
You may make any assumptions, but they should be well clarified.
Write a report as a consultant to propose your solution with full justification. The report should not exceed two A4 sides, excluding diagrams and appendices. You are advised to use as many diagrams as necessary to support your proposal.
-------------------------------------------------------------------------------------------------------------------------------------------------
What sort of things should I include in the report?
So far I've thought of these sections:
Assumptions
Hardware
Software
Security
Topology maybe?

why recommend wireless if they are all in fixed positions? we have a massive wireless network but thats because we are a college and all staff/students have laptops.

if it was me i'd advise against Wireless unless they have lots of mobile workers within the workplace.
could advise on a hard wired setup with the possibility of adding wireless access points later on if needed?
Just seems like they have asked for wireless because everyone else has it???

as for your report what you have mentioned seems fine, only has to be couple of pages. Get plenty of diagrams in there as they explain it much better than words. Ours was a nightmare to do - could try and find it and post it.

yea your report looks sound enough, i'd mention topologies before hardware etc. Diagrams are the key.
what course you doing BSc?

Be careful with 3D wireless network design as you've only got 3 non-overlapping channels.
Also the 'web server' they want should obviously be in a DMZ.
Although you'd have enough IPs in a Class C range to give everyone a public IP it's probably a better idea to use NAT so it's non-routable.

Yep done the DMZ.
I was just going to give everyone private IPs using DHCP. That gives soom room for expansion etc.....
What do you mean about the 3 non overlapping channels?

You've the same number of IPs to give out?
With DHCP of course, you'll have no idea where the hell the computer is that is causing your problems....

hhmm, good point, still not sure though.
Also, I spoke to the uni network manager and he suggested subnetting each floor, because that's how the uni have their network.
What would the advantage of this be?
I really dont want to subnet unless I really have to

Subnetting each floor is a bit old school as it goes back to the day when you didn't have switched networks (so you wanted to minimise traffic on the backbone). It still makes sense if you've got multicast traffic -- your subnetting should mirror your topology in my opinion.
Although it is probably good practice as it allows easier management (as Ian said) and possibility for IP-based ACLs, etc.
DHCP would be fine -- you could get still find out which machine was causing problems as long as you knew the MAC or hostname. Wireless and hotdesking causes a bit of an issue for finding the person though!

This is my logical overview, am I right in thinking I would need a proxy server?
