How to Use
Begin by unboxing the WisGate Developer CM4/CM4+/CM4P and inserting the Raspberry Pi Compute Module into the SODIMM connector on the main carrier board, ensuring proper seating with the retention clips fully engaged. Connect the 12V/2A power supply to the barrel jack connector and attach the LoRa antenna to the SMA connector, verifying secure connection to prevent impedance mismatch. Connect the Gigabit Ethernet cable to your local network or directly to a computer configured with a static IP address in the 192.168.100.0/24 subnet. Access the gateway web interface at 192.168.100.1 using default credentials, then configure your regional frequency band, LoRaWAN network server details, and GPS synchronization parameters through the intuitive dashboard.
For advanced development, install the Raspberry Pi OS or custom Linux distribution on the eMMC storage using the provided USB flashing tool, then SSH into the gateway using the command line interface for direct packet forwarder configuration and custom application deployment. Utilize the ChirpStack or Semtech packet forwarder software to connect to your LoRaWAN network server, configuring gateway location coordinates, antenna gain, and transmit power settings according to regional regulations. Monitor real-time gateway metrics including packet throughput, signal quality indicators, and GPS synchronization status through the web dashboard or MQTT API. For debugging and custom development, access the GPIO headers and serial UART interface to integrate additional sensors, implement edge computing logic, or capture raw LoRa packets for protocol analysis using specialized tools like gr-lora or LoRa packet sniffers.
Frequently Asked Questions
What is the difference between CM4, CM4+, and CM4P variants?
The CM4 variant includes 1GB RAM and 8GB storage suitable for basic gateway deployments. The CM4+ offers 2GB/4GB RAM with optional integrated WiFi 6 and Bluetooth 5.2 modules, ideal for applications requiring local wireless connectivity and edge processing. The CM4P is the industrial-grade variant with enhanced thermal management, -20°C to +60°C operating temperature range, conformal coating for moisture protection, and 4GB RAM with 32GB storage, designed for harsh outdoor and manufacturing environments requiring maximum reliability.
Can I use this gateway with The Things Network (TTN)?
Yes, the WisGate Developer platform is fully compatible with The Things Network through the Semtech Packet Forwarder software. After initial configuration, simply register your gateway on the TTN console using the gateway EUI (derived from the Ethernet MAC address), configure the TTN server address and port in the packet forwarder settings, and your gateway will immediately begin forwarding LoRaWAN packets to TTN infrastructure. The open-source nature allows complete customization of the packet forwarder to optimize for your specific TTN region and network requirements.
What is the maximum range and coverage area of this gateway?
The WisGate Developer achieves typical range of 5-15km in open space depending on antenna type, transmit power, and environmental conditions. In urban environments with buildings and obstacles, effective range reduces to 1-5km. The gateway can simultaneously communicate with thousands of end devices within coverage area, with capacity limited primarily by airtime utilization rather than hardware limitations. Using directional antennas and elevated mounting positions significantly extends coverage, making this platform suitable for city-scale deployments.
Does this gateway support Class B and Class C LoRaWAN devices?
Yes, the WisGate Developer supports all three LoRaWAN device classes. Class A is supported natively through standard uplink-downlink windows. Class B requires the integrated GPS module for beacon transmission synchronization, which is included in all variants. Class C devices receive downlink messages immediately after transmission, consuming more power but enabling real-time applications. The packet forwarder software automatically handles class-specific timing and scheduling requirements.
Can I add cellular backup connectivity to my gateway?
Yes, the WisGate Developer CM4+ and CM4P support optional 4G/LTE modules that provide automatic failover from Ethernet connectivity. When primary Ethernet connection is lost, the gateway seamlessly switches to cellular connection for packet forwarding to your network server. This is critical for remote deployments without reliable wired infrastructure.
