Performance Indicators Definition 4. Results 5. Conclusion 1. Background A comprehensive field test was conducted independently by TRA to assess and benchmark the performance of Omantel and Ooredoo mobile voice and data networks in Al Dakhiliyah Governorate. Field Survey Date & Time: 4th – 8th May 2015 from 9:00 A.M. to 10:00 P.M.

Key Performance Indicators Definition Mobile voice performance was measured based on the following set of KPIs: Call Setup Success Rate (CSSR)– This indicator is used to measure the percentage of calls successfully established without facing blockage in the network as a ratio of the total number of call attempts made to access and establish a voice call. (to check network accessibility) Call Drop Rate (CDR) – This indicator is used to measure the percentage of calls dropped due to technical problems or coverage gaps in the service provider’s network as a ratio of the total number of calls successfully established. (to check network retain-ability) Call Success Rate (CSR) – This indicator is used to measure the percentage of calls successfully established without facing blockage in the network as a ratio of the total number of call attempts made to access and establish a voice call and then successfully terminated from the user-end without being dropped or disconnected from the network side due to a technical irregularity. (to check service integrity) Mobile data performance was measured based on the following set of KPIs: Packet Latency - Packet delay, which represents the time taken for data packets to pass through the GPRS bearer in a round-trip time from the mobile to the server in the service provider’s core network and back to the mobile. (to check delay in the network) Ping Packet Success Rate is the percentage of packets lost between designated routes in the network. It is used to indicate the loss of data packets during transmission over a telecommunications network. (to check data integrity) HTTP Average downlink throughput - This is the average downlink throughput (rate at which data/bits are transferred to the user) experienced by a user while downloading content from the Internet. (to check download speed) Performance Indicators Definition continued Coverage is assessed based on the following radio parameters: Reference Signal Received Power (RSRP) – This indicator measures the linear average of the received power on reference signal resource elements in the downlink during the drive test (to check 4G coverage). Received Signal Code Power (RSCP) – This indicator measures the received signal code power of the pilot channel in the downlink during the drive test (to check 3G coverage). Received Signal Level (RxLevSub) - This indicator measures the received signal strength in downlink during the drive tests (to check 2G coverage). The following convention is used for the coverage plot. Serving Cell RSRP (dBm) 3G CPICH RSCP (dBm) 2G RxLevSub (dBm) Range Classification Penetration Range Range >= - 85 >= -80 >= -75 Excellent Indoor >= -95 and < -85 >=-87 and <-80 >=-82 and <-75 Good >= -105 and < -95 >=-100 and <-87 >=-95 and <-82 Fair In-Car >= 120 and < -105 <-100 <-95 Weak Outdoor Only 4.

Call blocking is found to be significantly high throughout the Governorate of Al Dakhiliyah on Omantel network. • Omantel mobile data network has good LTE footprint throughout the main Wilayat centers. No LTE coverage was found on Ooredoo data network throughout Al Dakhiliyah Governorate. • Omantel mobile data network exhibits good data performance with overall high download speeds and low network delay which is within the TRA threshold. • Ooredoo mobile data network exhibits fair data performance with overall good download speeds but the network delay is extremely high and does not meet the TRA threshold in any Wilayat or Town. Basis of results and conclusion • The coverage information is based on the geographical drive test route used during the measurement exercise. • The exercise has been conducted independently by the Authority without sharing any prior information with the service providers about the type of tests being performed or location. • The results of the exercise are based on the data collected from the field at a certain instance of time and day; network behaviour may vary with traffic variations over time and events. • Industry standard tools and work best practices have been used during the whole exercise. .

Commissioned into the King’s Regiment in 1954 having spent 2 years at RMA Sandhurst, and transferred to the Parachute Regiment in 1957. Attended the Defence Services Staff College in India in 1965. Served in the Sultan’s Armed Forces (SAF) in Oman for two separate tours, in times when Oman was threatened, both in terms of the security of the Hormuz Straits, and by South Yemeni communist movements which supported the rebel movement in Dhofar, the southern province bordering on the Indian Ocean. On first tour in 1971-72, Ashley was the Brigade Major of the then Dhofar Area and in the second in 1975-76, he was Commanding Officer (CO) of the Jebel Regiment. This Regiment’s Operation Husn was conducted in March 1975, it was a joint operation with other army units and the air force and was decisive. Ashley from his operations room coordinated the operation. The rebellion was declared over on 11 December 1975 and a ceasefire with Yemen was declared in March 1976. By this time, the Sultan’s army was organised into the Southern Oman Brigade, responsible for operations in Dhofar, and the Northern Oman Brigade. Ashley retired as a Lieutenant Colonel on 22 May 1986, and lived in Chipping in the Ribble Valley where he took an active part in local life.

Samples were taken from all provinces of the eleven governorates of the country and examined in Agriculture Research of honey bee Institute of Oman. The study showed that the S. tricuspis was found in five governorates out of the eleven governorates examined.This endoparasitoid was recorded in AL Batinah south, AL Batinah north, Al Dakhiliyah, Muscat and Ad Dhahirah. Samples from Dhofar, Al Wasta, Ashariqiya north, Ashariqiya south, Musandam and Al Buraimi were negative for infestation. We confirmed the presence of S. tricuspis in the mountain areas of Oman and diagnosed its existence for the first time in Oman, ) GBIF Global Biodiversity Information Facility, 2016). The presence of infestation in different provinces in each governorate was varied. The highest presence (100%) was recorded in Ad Dhahirah in the three provinces followed with Ad Dakhiliyah 87.5% from eight provinces, Al Batinah south, 66.7% from six provinces, Al Batinah north 66.7% from six provinces and the least presence was in Muscut governorate 16.7% from six provinces where the infestation was appeared in one province (Qurayyat).
