Terminals used in trials Samsung (B3710) • The most used terminal in trials and FiVe. • Drive test tool interface provides one sample per second (no averaging) for each parameter • 2.6GHz band LG (LD100/G7) • Provides more RF data (more frequent samples and parameters) than Samsung • 2.6GHz band Nokia (RD-3) • Support for 850MHz band Qualcomm chipset based terminals (QC, Huawei,…) • Still not widely used in NSN FiVe and trials (except in US) • Likely to be the most used chip set in short time Aeroflex TM500 • R&D test terminal, sw based • Provides TTI level data • Used for new frequencies and technologies when no other terminals are yet available. • Currently in use for 1800MHz band and for TDD.
Drive test tools XCAL • Support for Samsung terminal • Support for LG terminal • Support for PCTel and Rohde&Schwarz scanners
Samsung + XCAL, the most used drive test combination at the moment in trials and FiVe.
Nemo Outdoor • Support for LG terminals • Support for Qualcomm chipset • Support for Nokia terminals (RD-3) • Support for PCTel and Rohde&Schwarz scanners JDSU E6474A (NixT) • Support for LG terminals • Difficult post processing format (in Excel export). Post processing with drive test tool is difficult (not sync of different views). • Support for Qualcomm chipset (not tested yet) • Support for Samsung terminals coming early 2011 (?)

Scanner measurement information Best neighbor cell decoding sensitivity in NPO scanner comparison tests
PCTel • Measuring both RS SINR and SCH SINR • Wide band RSSI measurements and spectrum scanning supported R&S • Measuring only SCH SINR • No support for wide band RSSI measurements and spectrum scanning • Measuring only from Sync channel bandwidth (1.4MHz). Also RSRP and RSRQ measured only from that bw. JDSU E6474A • Measuring only RS SINR • Difficult post processing format (in Excel export) • Wide band RSSI measurements and spectrum scanning supported

Accuver XCAL, Nemo, TEMS, JDSU and R&S Romes In practice LTE file format change so quickly that the very latest DT file format is not properly supported (frequent issues with XCAL and with Nemo)
Simple failed/dropped LTE analysis in Spotlight only (not customizable) No LTE report with RF KPIs (only a common data session analysis)
Customized analysis (for e.g. acceptance reports) possible to do in Analyzer Classic if needed (integration with map plots not handy)
Possible problems with large data sets (days or weeks, depends on DT tool for e.g. TEMS is worst in that sense). Automation not possible Can be leased on monthly basis (1980€/month) Supports at the moment (March-2011) only Nemo Outdoor LTE. R&S Romes support coming 1H/2011(?). Suitable for large data volumes (automation possible) Built in default report for LTE (customizable MS Excel with map plots) Customized analysis and KPIs (for e.g. acceptance reports) possible once needed. Can be leased on monthly basis (1200€/month)

In theory many LTE drive test tools supported:
Support only for XCAL drive test data (LTE)(?) No experience in TM Global (not a preferred tool)
TEMS Discovery LTE – – – – –
Support for TEMS and QVoice LTE (later Nemo too) Not tested for LTE in TM Global (yet) Suitable for large data volumes (automation possible) Customized analysis and KPIs possible in theory (but in practice more complicated than with Actix or Nemo Analyze) Frame pricing should be available soon (with leasing option)
