(I haven't clicked on the link yet) I wonder if there is work that might occur from the business department end of things. Why do we have 15 years of WiFi optimization, which seem to be taking us further away from low latency. Are the new protocols actually improving the situation for the end consumer? My impression is no. Nobody notices because the quality is so unpredictable. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQFFBAEBCgAvFiEEbsyLEzg/qUTA43uogItw+93Q3WUFAmO0RNMRHG1jckBzYW5k ZWxtYW4uY2EACgkQgItw+93Q3WXdTAf/V1QzZpB1sc3whOOe9uZ6d06o75bIgrGi rfZVjkdxJnCu/HrvWf4VJH6IcEsjZiUwiU3EasMShdSKcoHtwox+txcG+dTg4HLc XsPXotF16Yrsr6xFlX3Si5K5ifphR9+hLH748ZjPYaJAVSPOEMpO+1w22QBD/PFE JHZD563eJSCSf3nErxH9f71gVT+eLNlKVVKQiX9VleRkT9CHh7X0ObPQzCC9Kss8 TgC9+fjJ0v801nxoddrcRAdoK0LU1R4grbvXPJ5fnM0nRxHeGpNe1RZ7z6UdNUtK 7qykFivxbEbKvLWkojgH78ANphP+ks+sCjTTlOBdpEscoP8qxik5dQ== =5W2m -----END PGP SIGNATURE----- --=-=-=--
