1. Overview
Y501-L receives LoRaWAN end-device traffic and forwards it to an external Network Server. It includes Ethernet, Wi-Fi, and RS485, with optional 4G backhaul. Optional local Network Server (NS) and Application Server (AS) software manages device sessions and application data on the gateway.
Choose an 8-channel or 16-channel configuration to suit the site's radio traffic.
| Item | Description |
|---|---|
| Product type | Indoor LoRaWAN gateway |
| Supported end-device LoRaWAN versions | LoRaWAN 1.0.2 / 1.0.3 / 1.0.4 |
| Supported end-device classes | Class A / Class C |
| Default frequency plan | CN470 |
| Supported frequency plans | CN470, EU433, EU868, AU915, IN865, AS923, RU864, US915 |
| Backhaul | 10/100 Ethernet and Wi-Fi; optional 4G |
| Operating environment | Indoor |
2. Model Configurations
| Configuration | Receive channels | Downlink channels | Selection profile |
|---|---|---|---|
| Y501-L, 8-channel | 8 | 1 | Lower concurrent radio traffic |
| Y501-L, 16-channel | 16 | 2 | More receive channels; two transmit paths |
Channel count describes radio paths. Device capacity depends on airtime, reporting intervals, payload size, interference, and downlink traffic. Regional limits, duplex mode, and server scheduling constrain downlink capacity even with two transmit paths.
3. Key Features
- Half-duplex or full-duplex radio hardware, selected when ordering.
- UDP/GWMP or MQTT packet forwarding, selected for the Network Server transport.
- Local web configuration and firmware upgrades; remote management where enabled.
- Optional local NS/AS services for device activation, sessions, and application data.
In forwarding mode, the external Network Server manages device activation and sessions; the gateway transports radio packets.
4. Technical Specifications
4.1 LoRaWAN Radio
| Parameter | Specification |
|---|---|
| Frequency plans | CN470 (default), EU433, EU868, AU915, IN865, AS923, RU864, US915 |
| Supported end-device LoRaWAN versions | 1.0.2 / 1.0.3 / 1.0.4 |
| Supported end-device classes | Class A / Class C |
| Channel configurations | 8 RX / 1 TX or 16 RX / 2 TX |
| Transmit power | Up to 27 dBm |
| Receiver sensitivity | Down to -140 dBm @ SF12, BW125 kHz |
| Radio hardware bandwidth range | 7.8 to 500 kHz; usable LoRaWAN settings depend on the regional plan |
| Spreading factor | SF7 to SF12 |
| Range test results | 470–490 MHz tests by spreading factor |
4.2 Network and Field Interfaces
| Interface or function | Specification |
|---|---|
| Ethernet | 10/100 Mbps RJ45 |
| 4G | Optional; module and operator-band coverage vary by ordered variant |
| Wi-Fi | 2.4 GHz; AP, STA, or AP+STA modes as specified for the hardware variant |
| RS485 | Standard A/B hardware; Modbus RTU data access requires the local-service software configuration |
| USB | MicroUSB USB-TTL debug and log interface |
| SIM card | Standard SIM card on 4G configurations |
| Configuration | Local web interface; remote configuration requires firmware support and enabled access |
4.3 Electrical
| Parameter | 8-channel configuration | 16-channel configuration |
|---|---|---|
| Supply | DC 9 to 28 V, typical DC 12 V | DC 9 to 28 V, typical DC 12 V |
| Maximum working current | 850 mA @ DC 12 V | 1.5 A @ DC 12 V |
| Average power | ≤3 W | ≤7 W |
| Maximum power | 10.2 W @ DC 12 V | 18 W |
4.4 Range Test Results
Y501-L range tests measured reception of end-device transmissions at 470–490 MHz.
| Test condition | Value |
|---|---|
| End-device transmit power | 22 dBm |
| Data load | Full data load at each spreading factor; frame sizes as shown in the results |
| End-device antenna height | 1.5 m |
| Gateway receiver chip | SX1302 |
| Gateway receiver sensitivity | -140 dBm @ SF12, BW125 kHz |
| Test frequency | 470–490 MHz |
Urban tests used locations with building obstructions and moderate interference. Open / suburban tests used good line of sight, few obstructions, and a higher gateway antenna.
| Spreading factor | Urban distance | Open / suburban distance | Frame size |
|---|---|---|---|
| SF7 | 0.5–0.7 km | 5.4 km | 222 bytes |
| SF8 | 0.7–0.9 km | 6.8 km | 222 bytes |
| SF9 | 0.9–1.0 km | 8.3 km | 115 bytes |
| SF10 | 1.0–1.1 km | 10 km | 51 bytes |
| SF11 | 1.1–1.5 km | 11.5 km | 51 bytes |
| SF12 | 1.5–1.8 km | 13.5 km | 51 bytes |
These test distances apply to the stated uplink conditions. Antenna placement and height, obstructions, interference, and radio settings affect site coverage. Test uplinks and downlinks at the installation site; other frequency variants require separate coverage checks.

7. Ordering and Deployment Notes
- Specify the frequency plan, channel count, and duplex hardware. For
AS923, include the sub-plan. - Match radio channels with the end devices and Network Server.
- Include 4G when cellular backhaul is required; check the module's operator-band coverage.
- Request local NS/AS and RS485 data-service software if needed. For Modbus access, agree on the gateway role and register map.
- Check the supplied connector set and antenna count, then attach the LoRa antennas before applying power.
