Kerlink’s Wirnet Gateway Simplifies LoRaWAN Network Deployment

June 27, 2019 Alix Paultre

Kerlink’s latest member of its Wirnet gateway family delivers 4G backhaul connectivity with fully integrated internal antennas, simplifying outdoor LoRaWAN IoT network deployments and management. The addition of 4G backhaul connectivity replaces 3G connectivity, which is inadequate in some situations. 4G also is a popular choice for cellular backhaul for data transport to cloud-based applications. Integrated antennas reduce deployment costs by eliminating the need for additional antennas used as accessories, and they comply with “right-to-use” for each antenna on some deployment sites.

Designed for global LoRaWAN deployments, Wirnet iStation supports multiple ISM bands, such as 868 Mhz, 915 Mhz, and 923 Mhz, and is certified by regulatory agencies in Europe (CE), the U.S. (FCC), Canada (IC), South Korea (KC), and other countries. Features include eight LoRaTM channels RX (125 kHz, multi-spreading factor) and 1 channel RX (250 kHz or 500 kHz, mono spreading factor) + 1 channel RX (FSK) to get 10 channel RX + 1 channel TX, allowing up to 1.3 million messages transmitted per day.

The gateway also supports bidirectional communication with a range of more than 15 km in suburban areas and more than two km in urban areas and comes in an IP67 light metal casing offering enhanced protection and large operating range in demanding environments. Additional features also include support for Ethernet 10/100 Mbps (RJ45), a SIM card (mini-SIM format) slot, Power over Ethernet (POE) or DC supply (e.g. for solar panel use), with remote power control and alerting.

The gateway has built-in high-rejection filters for co-localization with other radio devices, enabling strong interference resistance. It also has security features for software and hardware architectures such as Prove & Run SecureBoot and SecureStorage to safely manage certificates required for trusted communications through VPN backhaul, and to secure and protect applications running on devices.
