LGW915L Quick Start Guide

LoRaWAN Type III Indoor Gateway

1. Product Overview

1.1 What Is This Product?

The LGW915L is an indoor IoT gateway built on LoRaWAN® low-power wide-area network (LPWAN) technology. It integrates Semtech’s high-performance SX1302 8-channel transceiver, supports full-duplex operation, and can serve thousands of end-node devices simultaneously.

The gateway uploads data to the cloud via 4G, Wi-Fi, or wired Ethernet. It is compatible with mainstream LoRaWAN network servers (such as ChirpStack and The Things Stack), and can also work with the built-in network server (NS) or third-party IoT platforms, so you can deploy your own IoT applications quickly and flexibly. In this guide, the gateway is used with the AdoModel LoRaWAN NS cloud platform (http://adomodelcloud.com:4560/).

Key features at a glance:

  • 8-channel full-duplex LoRaWAN — Semtech SX1302 transceiver, handles thousands of end nodes.
  • Indoor deployment — designed for wiring cabinets, server rooms, and industrial indoor environments.
  • Flexible backhaul — 4G, Wi-Fi (2.4 GHz only), or wired Ethernet.
  • Open ecosystem — works with mainstream LoRaWAN network servers, the built-in NS, or third-party IoT platforms.

Figure 1 System architecture of a typical IoT deployment

How data flows through the system

  • Uplink: field sensors report their readings over an RS485 cable to a LoRaWAN-DTU, which packages the data into LoRaWAN frames and transmits them over the air. The gateway receives these radio signals and forwards them — via 4G or wired Ethernet — to the cloud, where the AdoModel LoRaWAN NS platform decodes them into application data.
  • Downlink: commands sent from the platform travel the reverse path. The gateway transmits them over the air to the DTU, which outputs them through its RS485 port to the sensor or controller.

The role of each component

ComponentRole in the system
Field SensorMeasures physical quantities (temperature, pressure, flow, etc.) and outputs data through its RS485 interface.
LoRaWAN-DTUThe translator between sensors and the wireless world: converts RS485 data to LoRaWAN radio frames, and vice versa.
LGW915L GatewayThe relay station between wireless and the Internet: receives LoRaWAN radio frames from end nodes and forwards them to the cloud over 4G or Ethernet.
AdoModel LoRaWAN NS PlatformThe brain of the network: manages gateways and devices, decodes application data, and provides web console, downlink control, and MQTT / REST API integration.

1.3 What This Guide Helps You Accomplish

This guide walks you through everything needed to get a single gateway from the box to a working connection with the AdoModel LoRaWAN NS platform. Follow the chapters in order; by the end you will have:

  • unpacked and verified the shipment (Chapter 2);
  • installed the antennas, SIM card (optional), and mounting hardware (Chapters 3–4);
  • powered the gateway and connected it to the Internet via Ethernet, 4G, or Wi-Fi (Chapter 5);
  • opened the gateway web console and verified its platform connection settings (Chapters 6–7);
  • seen the gateway appear online on the AdoModel LoRaWAN NS platform (Chapter 8);
  • learned what the platform can do for you once the gateway is online (Chapter 9).

If anything does not work as described, turn to Chapter 10 (Troubleshooting).

Connecting end-node devices (e.g., a LoRaWAN-DTU with sensors) to the network is covered in a companion document, the LoRaWAN-DTU Quick Start Guide.

The gateway itself never interprets your sensor data — it simply relays LoRaWAN frames. All intelligence (decoding, device management, integrations) lives in the NS platform. This separation is what allows one gateway to serve thousands of heterogeneous devices.

5. Power On & Network Backhaul

The gateway supports three backhaul options:

BackhaulBest forWhat to do
Ethernet (recommended)Fixed installations with a wired network available.Connect the Ethernet cable (Section 4.2) — the gateway obtains an IP address automatically (DHCP). No further configuration is needed.
4G (cellular)Sites without wired network access.Insert the SIM card (Section 4.2, power off first) — the modem dials up automatically after power-on.
Wi-FiSites with an existing Wi-Fi network.Power on, then configure the Wi-Fi connection (STA mode) on the gateway web console (Chapter 6 → Network → Wi-Fi). 2.4 GHz networks only — 5 GHz Wi-Fi is not supported.

5.1 Post Power-On Checks

  • The power adapter indicator is lit.
  • The Ethernet cable is firmly seated (if used).

Once powered and connected to the Internet, the gateway automatically starts sending data to the NS platform. In a good network environment the gateway comes online within 1–3 minutes of power-on (up to ~5 minutes). You will verify this on the platform in Chapter 8, after checking the web console settings in Chapters 6–7.

6. Accessing the Gateway Web Console

The gateway is managed through a built-in web console. There are four ways to reach it:

  • Option 1 — USB connection: connect directly to the gateway with the supplied Micro USB cable. Works even before the gateway has any network set up.
  • Option 2 — Ethernet via your LAN: connect the gateway to your router or switch and look up its IP address with the supplied LoraGW_IPScan tool.
  • Option 3 — Direct Ethernet connection (server mode): plug your computer straight into the gateway’s Ethernet port; the gateway assigns an IP address to the computer automatically. No network infrastructure or extra tools needed.
  • Option 4 — Remote access via the CMP platform: if the gateway is already online, open its web console remotely through the AdoModel IoT Management Platform (CMP) without going on site.

6.1 Option 1: USB Connection

  1. Locate the Micro USB port on the bottom of the gateway.
  2. Use the supplied Micro USB cable to connect the gateway to your computer.
  3. Open a web browser on the computer and enter the default gateway address: http://192.168.0.100:8088

The web console login page appears (Figure 6).

Figure 6 Gateway web console login page

6.2 Option 2: Ethernet via Your LAN

Use this method when the gateway is (or will be) installed on a local area network with a router or switch — the typical case for Ethernet-backhaul installations.

  1. Connect the gateway’s Ethernet port to your router or switch.
  2. Make sure the network has DHCP enabled — the gateway obtains its IP address automatically by default.
  3. Power on the gateway and wait about 40 seconds for it to finish booting and obtain an IP address.
  4. On a computer connected to the same LAN, open the supplied LoraGW_IPScan tool to find the gateway’s IP address. The tool can be downloaded from www.adomodeltech.com or obtained from your account manager.
  5. Enter the IP address followed by port 8088 in a browser — for example, if the search tool reports 172.16.10.107, enter: http://172.16.10.107:8088
Note

After logging in, you can switch the gateway to a static IP on the web console (Network → Ethernet) to suit your network environment.

6.3 Option 3: Direct Ethernet Connection (Server Mode)

  1. Using an Ethernet cable, connect your computer’s network port directly to the gateway’s Ethernet port.
  2. Power on the gateway and wait about 3 minutes. The gateway automatically assigns an IP address to your computer.
  3. Once the computer has obtained a valid IP address, open a browser and enter the server-mode address: http://192.168.100.105:8088
Note

Do not set the last octet of the server-mode IP into the .240–.250 range — those addresses are reserved for the gateway’s internal DHCP pool.

6.4 Option 4: Remote Access via the CMP Platform

Note

This option requires the gateway to be already connected to the Internet (4G, Ethernet, or Wi-Fi) and shown as Online in CMP.

  1. Log in to the AdoModel IoT Management Platform (CMP): http://adomodelcloud.com/ (account provided by your account manager).
  2. Click “Device Management” to expand the menu, then click “Group”.
  3. Enter the gateway ID (IMEI) in the search box and click “Search”.
  4. Click “View” on the found device.
  5. Under the operation column, click “Remote Configuration” (Figure 7).
  6. Confirm the device status is “Online”, then click “Enable Remote Connection”. Wait until a dialog confirms success and shows the “Open Configuration Page” and “Close Remote Connection” buttons.
  7. Click “Open Configuration Page” — the gateway web console login page opens.

7. Connecting to the AdoModel Platform

7.1 Verifying the NS Settings

The gateway is factory-configured for the North American band (US915) and for the AdoModel LoRaWAN NS platform. In most cases you do not need to change anything on this page — just verify that the settings match the table below.

  1. Open the gateway web console (Chapter 6).
  2. Go to “LoRaWAN Management” → “Parameter Config”.
  3. Verify the following values:
SettingExpected value (North America)
NS server addressadomodelcloud.com
Uplink port915
Downlink port915
BandUS915 (US_902-928)
Frequency points0–7
Note

If any value differs, correct it, click “Application” to save, then reboot the gateway for the change to take effect.

7.2 Using a Different Network Server

If you operate your own LoRaWAN network server (e.g., ChirpStack or The Things Stack), enter its address and ports on the same page. Frequency-plan customization is beyond the scope of this guide — see the companion Gateway Web Configuration Guide and the LoRaWAN band / custom frequency-point reference.

Note

If your gateway has not yet been registered on the platform, follow the registration procedure described in the companion LoRaWAN-DTU(LGW-L) Quick Start Guide, or contact your account manager.

8. Verifying the Gateway Is Online

8.1 Log In to the NS Platform

  1. Open http://adomodelcloud.com:4560/ in your browser.
  2. Log in with the account provided by your account manager.

8.2 Check the Gateway Status

  1. Click the “Gateway” tab on the left side.
  2. Enter the gateway MAC ID in the “Search” box and locate your gateway (Figure 8). If it does not exist, click the “CREATE” button in the upper left corner to create it.
  3. Check the status dot:
    • Green dot — the gateway is online and connected to the platform. You are done with this guide’s setup path; continue to Chapter 9 to learn what the platform offers.
    • Red dot — the gateway is offline. After power-on (or a new registration), the gateway typically comes online within 1–3 minutes in a good network environment, and within about 5 minutes at most. If it is still offline after 5 minutes, see Chapter 10.
Gateway list on the NS platform with a green online indicator
Figure 8 Gateway list on the NS platform — green dot indicates online
Note — Gateway ID rule

If the MAC ID on the label has 15 digits, append a “0” at the end to make 16 digits before entering it on the platform (e.g., 866999……7 → 866999……70).

8.3 Alternative Check via CMP

You can also confirm that the gateway has Internet access from the CMP platform (http://adomodelcloud.com/): search the gateway ID as described in Section 6.4; an “Online” status means the backhaul link works. If the gateway is online in CMP but offline on the NS platform, re-check the NS settings of Chapter 7.

9. What the Platform Can Do for You

Once your gateway is online, the AdoModel LoRaWAN NS platform is your window into the network. Highlights:

  • Applications & device management — organize end-node devices into applications; register devices, manage activation keys (OTAA), and monitor device status.
  • Live Data — view decoded application data from your devices in real time.
  • Live LoRaWAN Frames — inspect raw LoRaWAN protocol frames (e.g., JoinRequest / JoinAccept) for network debugging.
  • Downlink control — send commands to devices from the platform (e.g., through the downlink tool).
  • Integration — retrieve your data via standard RESTful APIs and MQTT subscriptions for custom application development.

A quick end-to-end walkthrough — registering the gateway and a LoRaWAN-DTU node, and testing uplink/downlink data — is provided in the companion LoRaWAN-DTU Quick Start Guide. The complete platform documentation is available separately (AdoModel NS Platform User Guide).

10. Troubleshooting

SymptomPossible causeWhat to do
