What can we do to save airtime?

• Stop advertising • AP hostname• 11ax data rates / capabilities

• Disable QoS

• Disable RSN

• Disable OWE

• Reducing customized Information Elements (IE)

Leave the Data Rates alone, REDUCE Co-Channel Interference….42

How Do I Love Thee?

How do I love thee? Let me count the ways.

I love thee to the depth and breadth and height

My soul can reach, when feeling out of sight

For the ends of being and ideal grace.

I love thee to the level of every day’s

Most quiet need, by sun and candle-light.

I love thee freely, as men strive for right.

I love thee purely, as they turn from praise.

I love thee with the passion put to use

In my old griefs, and with my childhood’s faith.

I love thee with a love I seemed to lose

With my lost saints. I love thee with the breath,

Smiles, tears, of all my life; and, if God choose,

I shall but love thee better after death.
