# Gateway Connectivity Options
The ASAS Gateway supports multiple methods (backhauls) for connecting to the internet or your backend systems, providing flexibility for various deployment scenarios.
# Overview
The primary goal of connectivity is to allow the gateway to forward received LoRaWAN data to ASAS server.
Supported backhaul methods include:
- Ethernet: Wired connection via the RJ45 port. Offers the most stable and often highest throughput connection. Typically the default and highest priority connection.
- Wi-Fi: Wireless connection to an existing 2.4 GHz or 5 GHz Wi-Fi network. Useful where Ethernet cabling is impractical. Can serve as primary or backup connectivity.
- 4G LTE Cellular: Mobile network connection using a SIM card. Ideal for remote deployments without access to wired or Wi-Fi networks. Requires a suitable data plan from a mobile carrier.
- Satellite Terminal (via RS485): Allows integration with specific satellite communication terminals using the RS485 serial interface. This is a specialized solution for extremely remote locations where no other connectivity exists. Requires specific hardware and configuration beyond standard setup.
# Connection Management
The underlying gateway operating system manages network interfaces.
- Priority (Typical): By default, the system often prioritizes wired Ethernet > Wi-Fi > Cellular when multiple connections are available and configured.
