High speed Wi-Fi ac technology is here and Wi-Fi Alliance claims that any certified device with Wi-Fi ac will deliver high speed.

Fair enough but in practice you are not likely to see any device with this new technology reaching the theoretical maximum speed of 1.3Gbps because the conditions you need to reach that speed requires a laboratory not your house or office. The first generation Wi-Fi ac hit a high of 331Mbps which is about 4x less – in the real world no-one ever gets close to theoretical speeds.

The Wi-Fi ac technology supports the 5GHz frequency which has far more room spread than there is in the over used 2.4GHz. The bad news is that 5GHz signal has less range which means higher bands are faster but lower bands travel further.

The Wi-Fi ac supports older Wi-Fi technologies, which means the performance of your newer device will be reduced due to your older device. You should always remember that any network is only as fast as its slowest link.

In a realistic setup – such as a growing large city – when everyone enjoys streaming video the congestion of bandwidth will always result in lower speeds.

But wait until many people will start streaming 4K or 8K video, then you will see your Wi-Fi network performance go down the toilet (Netflix is looking at streaming 8K in few years).

Technology is a wonderful thing: you may have noticed there was a 6 years gap to bring to market the Wi-Fi ac which is an eternity in technology terms. It was very expensive and hard to find and now you find it in every premium device. The next generation of Wi-Fi technology is expected for 2018 or later but it is much more to develop and test before we will see the first device available.

In summary, when planning to build a house it is recommended to work out the best combination between using Wi-Fi technology and installing sufficient cabling around the house to provide that infrastructure no matter what/when changes will happen in technologies and their associated costs. As explained above, upgrading your router will not be sufficient as any Wi-Fi network will be impacted by congestion and its slowest link (not many people will change their devices every 5 years). Therefore having a Lynxnet structured cabling system will prevent many future issues in your network performance.
