Wi-Fi Alliance is advocating for a common Quality of Service approach

5g wifi

In this paper released last week, Wi-Fi alliance is advocating for a single common quality of service that applies to all networks, including wired, Wi-Fi, and 5g wifi. This common approach can be applied across every type of network, because as the various technologies combine they will require a consistent end-to-end quality of service.

With 5G network expansion, it becomes more important to put Wi-Fi and 5G networks together in a quality of service fabric that is flexible and user friendly. Wi-Fi Alliance released a paper this week advocating for the adoption of quality of service measures across WiFi and 5G networks, utilizing the programs they already have.

With the Internet Engineering Task Force (IETF) RFC 8325, you can maintain consistent service quality across wired and Wi-Fi networks by mapping IETF’s differentiated service code point (DSCP) to IEEE 802.11’s user priority (UP), which is then mapped to Wi-Fi CERTIFIED Multimedia™ (WMM®) access categories.

The paper talks about two specific types of internet infrastructure that can be connected. In a scenario where fixed wireless access is used and 5G, the paper states that it may seem like they would work together seamlessly but they each have their own set of strengths.

Wi-Fi CERTIFIED QoS Management provides differentiated QoS for voice, video, best effort, background and so on. This is achieved by mapping DSCP markings to user priority access categories with Wi-Fi. As an example, in managed enterprises and carrier Wi-Fi networks, these QoSs can be achieved with a new mapping scheme that would be usable by network nodes including CPEs, client devices and 3GPP defined gateway functions.

Wi-Fi Alliance is developing QoS for the evolving Wi-Fi and 5G systems. By setting up end-to-end QoS, networks can maintain consistent quality of service for data flows across these networks.

"Consuelo Ortiz, Senior Product Manager at Wi-Fi Alliance, says 'Operators and ISPs should use Wi-Fi QoS Management and DSCP-5QI-UP mapping in their Wi-Fi devices, and submit their products for Wi-Fi QoS Management certification, in order to provide their customers a consistent connectivity experience for traffic traversing wired or wireless networks.'"

Who uses WiFi at 5GHz?

The 2.4GHz frequency should ideally be utilized to link devices for low bandwidth activities like Internet browsing. For high-bandwidth devices or activities like gaming and streaming HDTV, however, 5GHz is the ideal choice.

How far does 5G WiFi extend?

Many common Wi-Fi routers using the 2.4GHz frequency have a range of up to 150 feet (46 m) indoors and 300 feet (92 m) outdoors, without taking any outside influences or significant obstructions into account. In contrast, 5GHz devices typically cover about one-third of these distances.

Are 5G towers noisy?

(2) Many people utilize bluetooth to prevent any "radiation" from their personal phones because the cell towers will be far away from them (in addition to hands-free operation). (3) The noise produced by cell towers is comparable to that of an overhead airliner (or automobile traffic).
