Recently, the most common range for Wi-Fi routers has been: 2.4GHz. The fact is that such a frequency has better penetration, so it is perfect for large home spaces and corporate offices. At the same time, this range has two serious drawbacks: too much noise and data rate limitation. The problem is that Bluetooth devices and microwave oven magnetrons operate at the same frequency. This range is definitely not suitable for demanding tasks.
Range-enabled routers 5GHz It is in demand today more than ever. This band has 33 channels and can provide data throughput up to 1200 Mbps. Despite the lower penetration, interference is felt much less at this frequency than at 2.4 GHz.
Many Wi-Fi routers can now work on two bands simultaneously. The best solution for an apartment building is the 5 GHz band. At the same time, choose 2.4 GHz if you need wide coverage and Internet speed is not particularly important to you. Also, if you have an impressive budget and need to set up fast Internet in your home or office, it is better to choose a 5 GHz Mesh network or several repeaters.
It is also important to take into account the fact that now not all smart devices can operate at the 5 GHz frequency.
