[postgis-users] Represent WiFI signal via RSSI

[Darafei "Komяpa" Praliaskouski]

Hi,

RSSI has very complex shapes in the city terrain, not really following a
usable distance formula.

That being said I once upon a time got myself a ladder, excel spreadsheet
and measured one specific access point using my phone and regressed this
piece of formula.

0.2347 * exp(-0.07877 * (ap -> 'ss') :: float) as dst
