Furthermore, 3G providers can focus on promoting 3G through services such as “Friends and Family” packages as Chinese consumers’ 3G adoption decisions is influenced by their social network. (RSCP) within the defined coverage area Be replaced as under: Broadband data service requirements for NGMS licensee with UMTS technology(3G) Data throughput A minimum user data rate of 256 kbps typical Signal Strength (RSCP) A minimum outdoor signal strength of -100 dBm must be achievable with 90% confidence within the defined coverage area 5. In FDD mode (what we normally deal with) they are measured on the CPICH (pilot). Configuration Management 5. Elle est utilise comme une indication de l'intensit du signal, en tant que critre de transfert, dans la commande de puissance de liaison descendante, et. Mário tem 6 empregos no perfil. Cell coverage analysis - Measure Cell coverage covered by cell site per sector (Cell radius) by walk test or drive test and visualize data on Google maps. WCDMA PARAMETER SETTINGS ACCESS PARAMETERS IN IDLE MODE. e they replace the Measurement Control message used by UMTS. This research, would be benchmarking (compare) two 3G operators, HCPT and XL in Jakarta with 3 routes, and comparison parameters were RSCP (Received Signal Code Power), Ec/No (Energy Chip per Noise), Call Setup Success Ratio (CSSR) from compared call setup and call attempt, Call Drop Ratio (CDR) from compared call setup and call drop, Call. • Design and analyze network dashboard for 3G/4G KPI offenders. Sir , I have a doubt. e during LTE to UMTS reselection or handover. 3G) To check network accessibility, retain-ability, mobility, service integrity and coverage Calls of 90 sec duration with a 20 sec idle wait time between them to allow for cell reselection from 2G to 3G mode, where applicable. • Define and implement processes and procedures for RF engineering tasks (Definition of best. Omantel-Mobile data Dual (3G + 4G) To check data network performance and coverage downlink throughput,. 4 3G Handover Design 7. - Capacity dimensioning of sites and controllers for 2G/3G/LTE - Troubleshooting and recommending optimization changes to enhance the coverage and reduce the interference. NOTE: In case of handover to a 2G cell, [b1 threshold-GERAN] is sent by the network in RRC Connection Reconfiguration like the [b1 threshold-RSCP] which is for a 3G cell. In the UMTS cellular communication system, received signal code power (RSCP) denotes the power measured by a receiver on a particular physical communication channel. Just navigate our website www. With the radio coverage prediction software, we focused our tests on areas to obtain CPICH RSCP signal levels between −90 and −45 dBm. Analyze different networks (2G /3G/ LTE) KPIs and improve QoS: Analyze logfiles provided by Drive Test engineers and. Due to bad coverage "HANDOVER FROM UTRAN" occurred again and again. LTE measurement report triggering A1 Serving becomes better than threshold A2 Serving becomes worse than threshold A3 Neighbour becomes offset better than PCell A4. 3G-to-2G HOtriggering conditions, beside the signal quality evolution done by the UE, which is specified by 3GPP standard. Duration: 1 Day. Therefore it is now possible to use the 3G/4G cellular mobile network as a reliable backup-up connection of your main connection line. In an IEEE 802. This was achieved using a Load Balancing algorithm, which takes into account the channel element usage of 3rd Generation (3G) sites, and sets a Received Signal Code Power (RSCP) threshold value for each one. Support for AT&T, Verizon, T-Mobile and all U. “This year, we started to deploy directional cellular antennas and have started using the Octopus for the installations. Therefore it is now possible to use the 3G/4G cellular mobile network as a reliable backup-up connection of your main connection line. Active rsrp /rscp shows the same -141 even though i have full bars on phone. The reference point for the RSCP shall be the antenna connector of the UE. This means that UE will send measurement report for event B1 when it measures 3G cell RSCP above -102 dBm. It is usually given in dBm and can be calculated as follows: RSSI [dBm] = RSCP [dBm] - Ec/I0 [dB] As with RSCP and Ec/I0, it can only be measured in the code domain and needs the special monitoring equipment as described above. Site Auditing and Verifying Hardware, Tilt, Antenna height and Orientation, According to the site database.

In 3G, SCANNER HAVE ALSO IMPORTATNT ROLE FOR DRIVE TEST. 10: Optimization and Overview 1. In CDMA systems, a physical channel corresponds to a particular spreading code, hence the name (Received Signal Code Power). Based on the actual environment, analyze the specific causes to pilot pollution (for analyzing causes, see 6. Cell Reselection 3G -> 2G CPICH EcNo. •New sites and existing sites optimization include improvement in ECNO, RSCP, drops, Cell selection, Cell Reselection and Handover between 3G and 2G, and other drops due to quality or coverage issues. Ideally it should handover to CNU0071A with better EcNo and RSCP conditions to retain the call. From analyzing a • Derivative with respect to time of RSCP and EcNo. Ec/No= RSCP / RSSI (dB) Ec/No= 10 Log (CPICH Power/Total Transmit Power) RSSI stands for received Signal Strength Indicator, measured in dBm. If the cell is a micro cell, the default value should be modified according to the link budgeting result. and 3G coverage is sufficient, i. 006 The 2013 Iberoamerican Conference on Electronics Engineering and Computer Science Impact on Quality of Service (QoS) of Third-Generation Networks (WCDMA) with Pilot Signal Pollution Mariana Alejandra Eslava Gutiérrez * , Sergio Vidal Beltrán. pilot-signaali, RSCP) oli ennalta määritetyn raja-arvon yläpuolella.
