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.
Budget the network first and the gadgets second. A household that spends AED 800–1,200 getting coverage right and then adds devices over time ends up happier and cheaper than one that spends the same on devices that spend half their life showing an offline icon.
