A question we often get is should one go with a single band or dual band Wi-Fi receiver? It would seem logical to always go dual band, this way you can connect to both 2.4 and 5 GHz networks. This is not always the case.
2.4 GHz networks have been the most common type of network in the USA for more than ten years. In the last five years, dual band Wi-Fi routers have become more popular, even more so in the last 2 years with the introduction of 802.11ac routers that use both bands. The 5 Ghz band is a shorter range band but is less crowded and generally offers better throughput. The signal to which you are connecting has to be 5 Ghz though for the dual band adapter to connect on that band.
The FCC has more stringent power limits on 5 Ghz capable radios vs. 2.4 Ghz-only radios. Hence, single band adapters can have more power than even the highest powered dual band devices.
As we enter 2017, if you travel often, you will find there is virtually no place that does not offer a 2.4 Ghz signal, but 5 Ghz signals are usually only found in residential broadband modems and routers. Even public places that do offer 5 GHz capability will generally always offer a 2.4 GHz connection as well.
Therefore, if your goal is to be able to detect signals from the greatest distance when travelling, a 2.4 GHz high powered long range Wi-Fi receiver like Alfa AWUS036NH will be the best option. If you want to pick up from further away than your laptop’s stock card but do want to have 5 Ghz capability for home use also, Alfa AWUS036ACH is our highest powered dual band product.
Or, if you want to be covered for all situations, get both. With our low prices, you can get both items today for under $75.00 with free US shipping.
