Recommended data rates on 2,4 and 5GHz in an office

el_magneto — Fri, 02 Oct 2020 21:08:38 GMT

Hello,

What are the recommended data rates to set up on WING for best performance and quality?

enviroment: office

AP density: up to 15 AP per floor

client density: up to 10 clients per AP

client type: mostly PCs and Laptops with Win 7,8 an 10, couple of smart phones (iPhone, Android etc) and TVs.

At the moment I have default values:

But maybe I should change to this:

By the way. What is the differnce between “basic” nad “supported” type of data rate?

Best Regards

Hello Magneto,

I have attached a Wing Best Practices document and please navigate to the “802.11 Data Rates” page, which covers data-rates best practices for different deployments.

As for your inquiry regarding basic versus supported data-rates:

1. Basic RatesThe Basic Rate Set contains the rates that all devices in the cell must support; it is a sub-set of the Transmit Rate Set. All control, multicast, and broadcast packets are transmitted using one of the Basic Rates (as defined by the IEEE 802.11 standards). 2. Supported RatesWith wireless networks, there are many supported speeds depending on the standard of the hardware in use. For example, an 802.11b compliant device supports 11, 5.5, 2, & 1Mbps speeds. This capability information is passed in the beacons to inform the stations what speeds are supported on the access point. 3. Modulation and Coding Scheme (MCS)Modulation and Coding Scheme (MCS) is the quality of the radio channel, and thus the bit rate and robustness of data transmission. The process of link adaptation is a dynamic one and the signal and protocol parameters change as the radio link conditions change.

Thank you.

Why 802.11ax has no data reates to choose?

el_magneto,

The higher data rates (above 54Mbps) are determined by several factors. To actually list all of the possible rates in order to allow them to be used or not would fill up a large amount of interface space!...especially for 11ax.

Here is a list of the possible 11ax data rates. As you can see, there’s no way to include all of these in the WiNG interface.

What can be controlled though in the WiNG interface are:

Number of spatial streams
Channel width
Guard interval.

The modulation type and coding rate are not user-configurable. (By any vendor)

So by configuring the number of spatial streams, channel width, and guard interval, you can determine what MCS data rates will be possible.
