Of course the setup Johnsontp suggests makes sense.

What does not make sense is to try to feed smart phones over 60 meters with walls in between. It's a common error to assume that a single fat antenna for an AP would help in such situations, since not only the AP has to send radio signals to the smart phone, but the smart phone also has to send something back in order to be able to exchange data. Maybe, with a completely free line of sight this could work over 60 meters, but definitely not with walls, buildings or any other obstacles in between. Even for a WBS to CPE radio link you need a free LoS if you want a stable link.

Most of the mobile/laptop connections will be from (A) to (B) which is 10-15 metres and (B) has LOS to (A) through the front of the rooms.

That could be o.k. I used a WBS with a sector antenna to supply WiFi for end-user devices through a metal construction over a distance of 12 meters and since metal is a critical obstacle, the signal can be received through the windows only (glass is uncritical if not coated.

Sorry for all the questions but it is very hard to find real world information on these products.

Since it always strongly depends on local conditions, it's difficult to provide such information as wether the WBS will be better than your current device. If you want to do a professional installation, you would have to do radio measurement at the place to get exact figures (I do so at customer places before deciding which gear to install). Of course, this means you have to set up an AP with the antenna to be able to do such measurements.

2) What is the coverage range of these two devices using them on the roof of (B) as an AP.

For end-user clients the coverage range is the coverage range of the end-user devices. That's why Johnsontp suggest to use local APs indoor for client devices. Local APs such as the WR841 have much better antennas then smart phones and tablets. See, your current device almost certainly performs bad, b/c signal strength of client devices is weak. But 10 meters should be no problem even through a wall if it is not ferroconcrete.

If I go with Johnsontp's setup
1) What is the range of the TL-WR841HP V3 router?

I would say it's about 20 to 30 meters indoor with a wall in between in 802.11b/g mode and probably double that in 802.11n mode, but maybe Johnsontp has more exact figures.

2) How many of these devices would I need to connect in a three story brick building with 30 rooms separated by brick walls?

At least 2 or better 3 (one for each story). But take into consideration that the AirTime is divided by all 4 APs and by all 30 client devices! Read on.

3) Wouldn't a better setup be to have the (WBS210) & (TL-ANT2415MS) on the roof of (B) with a single CPE on (C) with LOS?

Sure, at least for (D). But for local coverage of (D) I would connect an AP to the CPE by wire. A CPE has directional antennas, which are suitable for directional links, not for omnidirectional coverage.

Anyway, it is very difficult to ensure that the WBS/CPEs used for the transfer network do not interfere with the local networks of 3 or 4 local APs in 2.4 GHz band. You just have not enough channels in this frequency band to ensure a clean setup. I would use 5 GHz equipment such as WBS510/TL-ANT5819MS and CPE510 for the transfer network and 2.4 GHz APs for local networks inside the buildings connected to the CPEs by wire.

But anyway, you have to test it before deciding finally, no matter which setup you want to choose.

Thanks again for all your advice, I have decided to go with the following configuration, hopefully it will work out well..
B) WBS210 + TL-ANT2415MS
C) CPE210 (pointed LOS at TL-ANT2415MS) + TL-WR841HP

Consider use of 5GHz devices (WBS510 / TL-ANT5819MS / CPE510) for the directional link, especially if you plan to add more CPE/AP combinations in the future.

1) if I mount cpe210's on the outside of the building will they work in client mode to feed the TL-WR841HP V3's via cable inside without MaxStream? ie. does the wbs210 act as an ap for the green beam and still feed the cpe210's?

Yes. But you are limiting AirTime for the CPEs meaning bandwidth will decrease proportional to users connected directly to the WBS.

2) if yes would there be a way to repeat the signal through to 'future expansion coverage area' (ideas on how?)

As I wrote: use 5 GHz feeds from WBS to CPEs, including the future expansion coverage area. Use TL-WR841 for indoor or EAP110-Outdoor for outdoor distribution of 2.4 GHz signal to clients. This way you get full 100 Mbit/s data speed of the Internet connection to all CPEs, TL-WRs and EAPs (equally divided) with best AirTime coverage possible. Use MAXtream (w/o 'S') if there are two or more CPEs connected to the WBS to get AirTime fariness.

3) what do I do about the people behind B) ?

EAP110-Outdoor. It covers 360°

4) maximum users 'mobile phone/laptops' would be 30-40 people (normally 10-20 people) (only Internet is needed no other networking)

Depending on surf pattern of your users, you would need two APs for 30-40 people if they should get enough AirTime to keep data flowing. If 30-40 users connect to a single WBS, expect significant drops in bandwidth due to CSMA/CA (see https://en.wikipedia.org/wiki/Carrier-sense_multiple_access_with_collision_avoidance). MAXtream helps to avoid this (among minimizing other problems such as the hidden node problem).
