Let’s start a successful partnership with ESG!
Electronics Solution Group Ltd (ESG) offers a range of legacy GSM antennas designed for reliable wireless communication with older-generation devices and systems. These antennas are suitable for applications based on GSM, GPRS, 2G and selected 3G communication standards, including industrial equipment, automotive tracking systems, security devices, telemetry, M2M terminals and legacy IoT installations.
These models are intended mainly for maintenance, replacement, service support and existing projects where GSM-based connectivity is still required. For new product designs or modern cellular applications, ESG recommends considering updated 4G / LTE / NB-IoT antenna solutions.
