Best wireless access point/repeater to use for 30m distance

I have been asked if there is a better wireless access point than the existing Belkin N600 in use at the moment to improve the wireless signal between office block and church computers.

The existing setup is Belkin N600 DB wireless N+ router (Model F9K1102v1) in the loft connected via CAT5 cable connection to the BT Hub 3 in the office which has a relative high download speed of between 12Mbps and 15Mbps (ADSL). The distance between the Belkin N600 and the computer that needs to receive the wireless signal is approximately 30m max. At present the signal is minimum too slow and useless, it cannot be used to download anything!

Unfortunately there is no duct between the two buildings and running a CAT5 or 6 cable is impossible because of the difference in height and the narrow road between the two buildings (see picture link attached).
I would appreciate if anyone knows of a better route/access point that can be used to improve the wireless signal between this two buildings.

Outdoor kit such as http://amzn.to/2tztD2G (£75) may help to improve reach but a better bet would be a pair of something like http://amzn.to/2uTj7nu (£60.75 each) Ubiquiti Loco M5

With both units outside and with line of sight 30m should be fine, indoor antenna will suffer from things like wet roofs and walls blocking signal

Is it a public road or private? What is the highest point you can get to on the lowest side?

If you can get to maybe 8 to 10m then a steel catenary wire between the two and external Cat6 attached to that could solve it.

Yes it is a private road within the church grounds.

The highest point of the lowest building is 6m.

We do need height clearance for refuse collection lorry!

Whether we use a steel catenary wire or Nano M5 what cat cable would be best to use to connect it to the existing Belkin access point?

To the right of your 6m height is a tower ... if you could get from the 8m point to there and then run along the walls could be one option.

Or given that 6m is 20 feet, you may be OK as it is private land. A double decker bus is only 4.5m so check the refuse lorries and see what their maximum is and see how that compares to 6m. And by going to the guttering fascia level you might get some more.

A tight wire may droop 0.5m over 30m - my phone drop wire itself is 50m long and does not droop by more than about 1m.

As for cable - external Cat5e or Cat6 - no need for armoured, just UV protected..

I notice that the Ubiquiti Loco M5 is for a frequency of 5 GHz forgive me I don't know anything about frequency but will this work with BT Hub 3 which is 2.4 GHz although the Belkin N600 to which it is connected to is 5 GHz and 2.4 GHz capable and from which the Ubiquiti Loco M5 would be connected, so if the Belkin is set to 2.4 GHz same as the Hub 3 will Ubiquiti Loco M5 work?

You require a pair of external AP's

but a better bet would be a pair of something like http://amzn.to/2uTj7nu (£60.75 each) Ubiquiti Loco M5

The wireless on these Ubiquiti devices will not be available for end users to connect to, it is just used as a bridge.

So in your situation

Your hub 3 is connected (cat5) to one exterior AP.................wireless link to other AP on the remote building then that is connected either to PC (Cat5) or another wifi access point with a broadcast wifi signal.

Do not connect between the buildings that far apart using a Cat5/6 cable, you will create something called a ground loop, the wireless option is best and a much simpler installation method all round.

If you decide against using wireless, then use a fibre connection between the buildings which do not cause a ground loop.

The first thing that I need to clarify, which is not very clear from your comment above, is will a 5GHZ only AP such as the Ubiquiti devices work with the BT Hub3 which is 2.4GHz? Otherwise it is not worth thinking of using the Ubiquiti devices and having to find similar devices that are 2.4GHz.

From your comment

Your hub 3 is connected (cat5) to one exterior AP.................wireless link to other AP on the remote building then that is connected either to PC (Cat5) or another wifi access point with a broadcast wifi signal.

Using a point to point bridge is the easiest way to get an internet signal to the other build as a catenary wire complicates how the cable can be run which would be quite a long length because of the structure of the build and the private road between the two buildings so a point to point would be preferable.

Am I right in thinking that what you are saying is that from the existing Belkin AP in the say host building, connect the Ubiquiti devices and connect the remote Ubiquiti device to an AP and from this AP so as to have wireless access and also hardwire connect it to the desktop in the other building?

Just to clarify we do not intend to give people wireless access, as it is a church, but just connect a desktop in the other building to the internet assuming that the 2.4GHz Hub will work with the 5GHz devices.

A catenary wire would be difficult to run as it would require it to be extended a long distance because of the private road between the two buildings and thus make the cable run almost 100m or more long!

A point to point bridge would be preferable.
