VoLTE Lab

complete test suite for Voice-over-LTE

VoLTE Lab is a complete test suite for Voice-over-LTE, that includes the LTE LabKit, the Yate MiniCore and two iPhone 6s. It is fully configured and intended for use as a VoLTE test bed and learning environment.

VoLTE Lab allows the detailed assessment of the involved technology, and is able to clarify your needs in terms of higher scale VoLTE acquisition.

Components

  • iPhone 6s: UEs with a very good VoLTE implementation
  • LTE LabKit: a highly configurable test eNodeB/BTS with three GSM and one eNB modes
  • Yate MiniCore: a software-defined compact core network for LTE/IMS and GSM/GPRS, intended for MNOs and MVNOs

Features

  • Fully configured, fully functional VoLTE test suite
  • Built on general purpose hardware
  • Running Yate/YateBTS/YateENB software on Linux
  • Three management interfaces (SSH, HTTP-local and remote)
  • Easy to order, worldwide delivery
  • Easy licensing system
  • Affordable price
