+**How will 6 GHz impact wireless design?**
+**Cell Size and Density of APs**
+**Higher frequencies**, such as 5 GHz and 6 GHz, produce a **shorter wavelength**. This means they travel a shorter distance than the longer wavelengths of lower frequencies (from our days in college physics – wavelength and frequency are inversely related, if one is higher, then the other is shorter). Shorter distances for the higher frequencies create smaller cell sizes.
+So how will this impact your network? **Smaller cell sizes and transmit power limitations will increase the density of APs in your design**. One of the most important components of network planning (and costliest if done incorrectly) is determining the right number of APs and where to put them. Incorrect placement or the incorrect number of APs can create major problems for your network, negatively impacting signal strength and channel interference, as well as causing roaming issues. This results in costly network outages, downtime, or loss of productivity.
+If you are designing a multi-band network, you will have to pay close attention to the number of APs and make sure you are not buying excessive hardware.
+**More Attenuation in Higher Frequencies**
+Another challenge for wireless network design in 6 GHz is attenuation. Higher frequency waves can be more impacted by attenuation than low-frequency waves. This is potentially problematic as you will have to account for the increased attenuation in your network design. You will want to perform a survey to validate the performance of the environment. The challenges don’t stop here. There will be several others that can impact your network design such as roaming. You will want to make sure you account for these challenges as more information is made available for 6 GHz.
+**Designing for the Future: 6 GHz vs. 5 GHz**
+In environments such as large public venues (LPV), education, traditional enterprise, and healthcare, a 6 GHz network may make sense due to capacity and Quality of Service (QoS) functions that are critical. In manufacturing and warehousing environments where you need bigger cell sizes, and may have older technology still in use (handheld scanners etc), a 6 GHz design may not be the best route. You will still need to utilize the 2.4 GHz frequency.
+As our world continues to consume and innovate using wireless technologies, this expansion plan will increase the amount of available spectrum for Wi-Fi by almost a factor of five, according to the FCC. In a communication from the FCC published today, “The FCC has adopted new rules for the 6 GHz band, unleashing 1,200 megahertz to boost #WiFi and other unlicensed uses to usher in faster, more efficient broadband connections…”.
