In-Depth Internal Component Analysis / Teardown
A close examination of the internal component photographs reveals a sophisticated design focused on wireless performance, power integrity, and serviceability.
The main PCB is densely populated with high-quality components, reflecting a mature design philosophy. Dominating the board is a large, shielded module near the center-left, almost certainly a Quectel EC25 or similar LTE cellular modem. This module integrates a baseband processor, RF transceiver, and potentially GNSS capabilities, forming the backbone of the device’s cellular communication. Surrounding the LTE module are several power management ICs, memory chips, and what appears to be a local microcontroller, all in modern QFN and TSSOP packages. The PCB itself features a blue soldermask and is likely a 4-layer or higher FR4 board, with extensive ground pours and stitching vias to ensure optimal RF performance and EMI suppression. A prominent coaxial cable connects the LTE module to a large, dedicated PCB or FPC antenna, ensuring strong cellular reception. Additional connectors, including a SIM card slot and multiple FPC/FFC interfaces, support flexible system integration and future expansion. The lower section of the board houses three large cylindrical lithium-based cells, providing robust backup or primary power, while a well-laid-out array of inductors and capacitors handles DC-DC conversion and power filtering. The overall build quality, attention to EMI/RFI control, and modular component selection signal a device designed for reliability in critical access control applications.
A second internal perspective further underscores the WallCall Unit’s engineering rigor. The central focus is a shielded cellular modem module—typical of certified LTE solutions—flanked by power management ICs and a probable microcontroller, all efficiently laid out on a blue, high-density PCB. The board employs advanced signal routing, with controlled impedance traces and extensive ground pours particularly around the RF section, indicating careful attention to high-frequency integrity. On the enclosure’s left, a flex or PCB antenna is securely connected via a coaxial cable, tailored for LTE bands, while a second antenna connection at the top hints at diversity or multi-band support, possibly for Bluetooth or Wi-Fi. The lower area accommodates two large cylindrical lithium-ion cells and a substantial electrolytic capacitor, ensuring stable power delivery. Multiple connectors—including FPC/FFC and coaxial types—enable modular expansion and ease of service, while the visible test points and probable debug header support manufacturing and field diagnostics. This internal configuration highlights a device purpose-built for robust wireless communication, EMI resistance, and straightforward maintenance, aligning with the demands of secure, always-on access control.
