3. COVERAGE 3.1. 4G, 3G & 2G Coverage. During the survey period, the mobile handsets were kept in auto detect mode i.e. preferably on 4G and fallback to 3G or 2G depending upon the availability of the network in particular area, therefore, majority of the time the handsets remained on 4G network. While traversing the routes, the level of signal strength received on mobile handsets have been recorded. The 4G Reference Signal Receive Power (RSRP) and 3G Received Signal Code Power (RSCP) i.e. recorded samples of signal strength of all Cellular Mobile Operator (CMOs) is shown as below: LTE COVERAGE (RSRP) RECORDED IN LAHORE

3.2. 4G Coverage. The pictorial view of signal strength of 4G networks of CMOs i.e. Jazz, Telenor, Ufone and ZonG is shown below: LTE (4G) RSRP SIGNAL STRENGTH

Page 3 of 13

3.3. 4G Signal Strength. RSRP is the average power of Resource Elements (RE) that carry cell specific Reference Signals (RS) over the entire bandwidth, so RSRP is only measured in the symbols carrying RS. As per license the signal strength should be greater than -100dBm with 90% confidence level. Following graphs show overall average value of RSRP alongwith its confidence level and percentage distribution in different ranges (i.e. bins from greater than - 65dBm to less than -100dBm). None of the CMOs have achieved the 90% confidence level in Lahore.

Threshold Value > 99% Grade of Service is the probability that the end-user cannot access 2. Grade of Service the mobile service when requested. In simple words it is the network blocking. Threshold Value < 2% Service Service Accessibility is the probability that the end user can access 3. Accessibility the desired service. Threshold Value > 98% Call Connection Time is the time between sending the complete Call Connection 4. call initiation information by the caller and in return receipt of call Time setup notification. Threshold Value < 6.5 Seconds Mean Opinion Mean Opinion Score is the quality of voice call. Threshold Value > 5. Score 3 Call Completion Ratio is the probability that a service once Call Completion obtained, will continue to be provided under given condition for a 6. Ratio given time duration or until terminated deliberately by either Caller or Called Party. Threshold Value > 98% ISHO for CS Inter System Handover is the measurement of successful handover 7. Voice from 3G to 2G for Circuit Switched Voice. Threshold Value > 98% RAB Setup The probability that RAB will be assigned to mobile user for any 8. Success Rate service when requested.
