Handy solution embedded in smart phone

Smartphone based network QoS
and QoE logging solution including Voice MOS

XCAL-Solo is a handheld air interface measurement tool for QoS, QoE test for GSM, CDMA, WCDMA and LTE-A (up to 4CA) without any limitation by attaching portable H/W to Smartphone to cover wide range application testing, including Audio MOS measurement, network measurement and data on the smartphone in real time base.

XCAL-Solo also supports creating and editing measurement scenario and various auto call tests (Voice, VoLTE, FTP, Web, E-Mail, Iperf, Ping, YouTube, Multi-Call, Multi-RAB, Multi-Session) with user friendly touch interface from Android OS GUI.

  • Use XCAL-Solo to

    • Performing handheld Field Testing and In-Building Testing
    • Providing real time based RF data monitoring and statistics with message, graph and table
    • Portable design for gathering and checking DM log, main KPI information rapidly
    • Collecting full DM data by using smart phone
  • Benefits

    • Overcome the limits of XCAL-Mobile by connecting portable H/W
    • Can be used without any limitation on the smartphone supporting DM interface and Linux driver
    • Support POLQA since it has sound card in portable H/W and audio interface with cable
    • With the help of small H/S, DM is collected in portable H/S through USB DM interface like XCAL
    • Important KPIs are echoed to a LCD screen of smartphone in real time from a portable H/W
    • Auto call is running in XCAL-Mobile and logging file is stored in portable H/W
