paraHO,
but measurements are not the same as “being able to make a call”… MS are supposed to be able to make a call at -102dBm (minimum performance defined by 3GPP).
however, due to fading, body margin, interference… this value is very difficult to achieve. That’s why a 10dB security margin is the least any radio planner would take to cover his … “arse” 🙂 (that’s how they say in UK, right ?)
cheers,
