So here's the deal- I work in an office with around 100 staff, and the office is laid out as an open-plan square, with a central square hole where the lifts and lobby is. UFB has just been installed, to be used by contractors and guests, and staff for their smartphones. The UFB is totally disconnected from the corporate LAN. (In the future we'll engage our IT vendor to install a "proper" on-LAN FortiNet managed solution but that's $10,000 and ~12 months away.)

The supplied UFB modem/router is in our comms room and due to the number of walls etc., the Wi-Fi signal does not penetrate very far.

The question is- what's the best way to deploy around 4 access points (one in each corner) to ensure full AC-class coverage around the floor? Obviously we have structured cabling (Cat 6) so can easily reach the APs from the comms room via that. I guess there may be ~25 connections per AP, but not all of them will be active at once. We have an account with PB Tech so preferred purchasing is their range of AP's and I'd like to keep costs under $1k for the lot.

Do I run four separate Wi-Fi LANs, use some kind of repeater/range extender or is there a way of having a single SSID broadcast with no loss in bandwidth due to overlapping AP's? Should I ignore the original Wi-Fi on the router in favour of a clean external deployment? What product would you recommend from PB Tech's range to do so?

Any comments appreciated...

Cheers
