Document adding 16 channel Gateway in the TTS

[i3mSuperMan]

Summary

The Things Stack already supports 16 channel UDP and LBS( Concentrator Design v1.5) Gateways. To configure a gateway with an additional frequency plan, Users need to set the --frequency-plans-ids option which accepts an array, and note that both frequency plans must be from the same PHY region.
ttn-lw-cli gateways update <Gateway ID> --frequency-plan-ids EU_868_870 //or whichever

Why do we need this?

To connect 16 Channel UDP and LBS Gateways with TTS.

@KrishnaIyer , do you have a 16 channel gateway and know how this needs to be done?

[KrishnaIyer]

Nope I don't have a gateway.

We don't have a gateway and the vendor we asked for assistance did not respond. Removing the milestone.
