The answer to the question, no it’s not all wireless. We know its 2022 and technology has advanced hugely over the years, but wires play a very key component to an efficient smart home.
The most important thing to remember is having a good wiring backbone, and that just doesn’t mean cables flung everywhere, without due care attention.
The type of cables you’re using, their properties and intended purpose is very important.
When cabling we ensure we run cables in a manner that doesn’t put strain on them, where we can well use cable trays and ducting to ensure cables are shielded from EMI (Electromagnetic Interference). Once the cables have been ran we then test every single cable to ensure it passes the ratings for its purpose. This report is then handed over to the client as proof that the cabling we’ve ran in will do its intended job.
