Concrete walls and mesh wifi: the budget line nobody plans for
UAE construction is unkind to wifi. Most villas and towers are built from concrete block with cement render, often with steel reinforcement, and a single router in the living room will not reliably reach a doorbell at the gate, a camera in the maid's room corridor, or a lock on a door two concrete walls away. Smart devices that drop offline are the number one source of buyer's remorse in this category, and the fix is almost always network coverage, not the device.
A proper installer starts with a walk-through signal check before quoting, because the network work can cost more than the devices it supports. A three-node mesh setup, placed and configured, generally runs AED 300–800 depending on whether nodes can use wired backhaul. Here is a genuinely money-saving detail: many UAE villas built in the last fifteen years are pre-wired with ethernet points feeding back to a central patch panel, usually in a hallway cupboard. If yours is, wired backhaul between mesh nodes is nearly free to activate and dramatically better than wireless hops through concrete.
