Our digital world runs on data. WiFi is an excellent solution for temporary local connections, but it has severe limitations. WiFi's inherent insecurity, low bandwidth, and spotty reliability mean that data cabling is still the king for zipping information about the world at a fast enough pace to satisfy our insatiable appetite for information, and high-fidelity digital entertainment.
Year upon year, the world creates more and more data, creating an increasing demand for more bandwidth delivered at higher speeds. CAT5 ethernet data cabling used to be the order of the day for small to medium-sized business or even a well-connected home, but its maximum throughput may no longer be enough for today's gigabit capable networks.
If your needs are modest and you have a low budget, then the 1Gbps speed limitation of CAT5 may be perfectly acceptable. However, with network hardware increasingly capable of speeds over 10Gbps and 4K video streaming becoming the norm, then CAT6 data cabling is the most financially sensible long-term strategy for future proofing your network.
CAT6 data cabling runs need to be significantly shorter than CAT5, but the low levels of crosstalk ensure an incredibly reliable network that will keep your 4K video stream stutter free and telephone communications crystal clear.
For the ultimate in a Gigabit network that will stand the test of time, CAT6A (A for Augmented) should be your data cabling of choice. You get the 10Gbps capability of CAT6, but the distance is increased to double. Plus, you also get the benefit of 500MHZ of bandwidth. Network hardware will become increasingly sophisticated over the years, so you want to be sure your infrastructure can take full advantage of it.
