LTE Drive Test Procedure

LTE Drive Test Procedure for SSV Etisalat UAE

Coverage Test • The objective of this test is to check if there's swapped feeders and if the Radio Units and Antennae are radiating as supposed to be. • - near the site we should receive -70 and the PCI should be as planned. • - the test is done by driving all the roads around the sites in idle mode ( just plugging in the data card and make sure it is camped on LTE without doing any kind of browsing or download) • - on Tems you should monitor the map and the radio levels ( RSRP, RSRQ, SINR, PCI) >>> windows on Tems : LTE Serving /Neighbor Cell. • Note: you activate the card and when ur in idle mode n u can see the signals>> u start logging and then drive and when u finish driving u stop logging.

Handover Test •

HO test is done in dedicated mode >> connecting to filezilla and downloading big file and driving

• • •

The objective is to know if the HO is working between the 3 sectors of the site. >> drive clockwise and counterclockwise around the site and near, and monitor that that the PCI is changing from one sector >>> windows on Tems : LTE Serving /Neighbor Cell and another Windows Events.

• • • •

Another drive is needed to check the HO to neighbor site. Just check one neighbor per cell to conduct a HO test and vice versa. Neighbors are chosen based on availability If theres huawei and ericsson sites as neighbors two tests should be done

•

Note: you activate the card and and u start downloading big file from Filezilla when ur in connected mode n u can see the signals and download working>> u start logging and then u drive and when u finish driving u stop logging.

Throughput test • •

• • • •

For each cell we should do 3 DL test and 3 UL Test >> for a site >>18 tests >> 18 log files The throughput test is a static test>> no drive >> just find a location in front of the sector where radio conditions are the best ( SINR>>22/25, RSRP>> -70/-75) And do the tests for each sector in the location chosen During test you make sure you are always camping on same PCI ( the one of the sector) >> >>> windows on Tems : LTE Serving /Neighbor Cell And make sure that most of the time that transmission mode is 3 ( MIMO), RI=2, TS01 and TBS02 is 64QAM during DL for PDSCH Modulation and PUSCH modulation is 16 QAM during UL test. >> Windows in Tems : LTE radio paramters

DL & UL Throughput test • For DL and UL tests, they should be done using Filezilla and connecting to the FTP server and downloading 10 big files for DL and 10 big files for UL. • While monitoring the throughput through netpersec and take snapshot when we reach the target. • For 2600 sites : target : average throughput DL= 60 Mbps and for UL = 30 Mbps • For 1800 sites: target : throughput DL= 30 Mbps and for UL = 15 Mbps • U should do the file transfer and when its stable on the high throughput start logging for 2 min. • In total you shuld have 18 log files per site and 18 snapshots.

DL & UL Throughput test graph

Latency (RTT time) test • Open command prompt from windows and ping the ip address of the FTP server on same location u where doing the throughput test and take snapshot of the blck window. • We do it once per sector • Kindly note that before pinging start logging and after pinging stop logging
