We provide Single-channel LoRaWAN Gateway is a simplified and cost-effective alternative to a full-fledged LoRaWAN gateway. While it doesn't comply with the full LoRaWAN specification (which requires multi-channel and multi-spreading factor reception), it's often used for development, testing, or small-scale applications.

Here are the typical specifications for a Single Channel LoRaWAN Gateway:

🔧 Hardware Specifications
Processor: ESP8266 / ESP32 / Raspberry Pi / STM32 or similar microcontroller
LoRa Transceiver Module: Semtech SX1276/SX1278
Frequency Bands:
a.) EU868 (868 MHz)
b.) US915 (915 MHz)
c.) IN865, AS923, AU915, etc. (region-specific)

1. Spreading Factor (SF): Configurable (typically one SF like SF7 or SF12)
2. Bandwidth: Usually 125 kHz
3. Channels: Single channel (fixed, e.g., 868.1 MHz)
4. Power Supply: 5V via USB or battery
5. Antenna: External SMA antenna (2 dBi to 5 dBi typically)

Communication Interface:
a.) Wi-Fi (ESP-based)
b.) Ethernet (if Raspberry Pi used)
c.) USB-UART (for development)

🌐 Network & Protocol Support
1. LoRaWAN Compatibility: Partial (not LoRaWAN compliant for production networks)
2. Supported Protocols: LoRa, basic LoRaWAN uplinks

Backhaul Options:
a.) Wi-Fi (most common)
b.) Ethernet (Raspberry Pi or other SBCs)

Packet Forwarder:
· Custom single-channel packet forwarder
· LoRa Gateway Bridge (basic setup)
MQTT/UDP Support: Yes (used to forward data to LoRaWAN servers like TTN)

📡 Performance Parameters
a.) Receive Sensitivity: Around -137 dBm (depending on SF)
b.) Transmit Power (for TX-capable gateways): 14 dBm to 20 dBm
c.) Range: 1–5 km in open area, less in urban settings
d.) Uplink only: Typically only uplink support (no downlink or ACK)

🧰 Common Use Cases
a.) Development & testing of LoRa end-nodes
b.) Indoor small-area coverage (labs, homes)
c.) Low-cost learning platform
d.) DIY IoT and home automation projects
