1. A method performed by a mobile station (MS) operating in a wireless network, the method comprising:
- measuring a first signal strength received at the MS from a first base station (BS1);
measuring a second signal strength received at the MS from a second base station (BS2);
receiving first path loss parameter values at the MS broadcast from the BS1, wherein the first path loss parameter values comprise at least one of a value of transmit power at the BS1, an antenna height associated with the BS1, or a geo-location of the BS1;
receiving second path loss parameter values at the MS broadcast from the BS2, wherein the second path loss parameter values comprise at least one of a value of transmit power at the BS2, an antenna height associated with the BS2, or a geo-location of the BS2; and
calculating a location of the MS using the measured first signal strength, the measured second signal strength, the received first path loss parameter values, and the received second path loss parameter values.

Abstract
Embodiments herein may use first and second path loss values L1 and L2 to calculate first and second distances R1 and R2 between the MS and first and second base stations BS1 and BS2, respectively, in a wireless packet-carrying network. L1 and L2 may comprise values of a reduction in signal strength of signals as transmitted by the BS1 and the BS2 and as received by the MS. The MS may triangulate its position relative to a grid using R1 and R2. Other embodiments may be described and claimed.
