EP650 Broadband Trunking Terminal

EP650, a hand-held device independently developed by Huawei, is a broadband trunking terminal with powerful functions applicable to professional trunking networks. It supports private calls, group calls, short message services (SMSs), multimedia message services (MMSs), broadband data access, video dispatching services, and multi-service concurrency. EP650 can be widely used in fields such as public security, energy, and transportation, completing professional trunking dispatching, multimedia dispatching, and broadband data access functions.

Based on the appearance of traditional walkie talkies, the compact and robust design of EP650 is oriented towards the demand of public security. The outstanding features of EP650 are as follows:

  • Support for a wide range of frequency bands, meeting the demands on multiple frequency bands
  • EP650 supports frequency bands 1.8 GHz, 1.4 GHz at the same time.
  • Outstanding performance, meeting the requirements of professional users
  • PTT setup delay < 300 ms and call apply/call preemption delay < 150 ms
  • Clear voice quality against strong background noise and application of the noise-canceling dual-microphone (dual-MIC) technology
  • Leading multimedia dispatching solution, completing site-related works using only a terminal device
  • Integrated with functions such as private calls, group calls, SMS, MMS, video uploading, and mobile office
  • Supports D1 25fps video transmission, dispatching and distribution
  • Supports attached USB cameras for applications in complicated environments
  • Supports one-click video uploading and one-click photo uploading
  • Designed to meet requirements of professional users, endurable in adverse circumstances
  • Equipped with 2.4-inch semi-transparent semi-reflective TFT screen and endurable Gorilla Glass surface
  • With IP67 protection level and can be properly used after being submerged 1 m underwater for 30 minutes
  • It is of high reliability and complies with the MIL-STD 810F standard.
  • Direct mode operation (DMO) enables it to communicate anywhere at any time.
  • Software can be upgrades automatically and parameters can be changed remotely using OTA.
  • End-to-end security design, ensuring the safety of user information
  • Bidirectional authentication
  • Air interface encryption
  • Remotely Enable/Disable Terminal
