Choosing the Right LoRaWAN Gateway For Your Application
LoRaWAN is an openly available wireless protocol that sits on top of LoRa, one of the leading emerging standards for supporting long-range wireless sensor technology.
LoRa uses a proprietary modulation scheme developed by Semtech called chirp spread spectrum that is resistant to multi-path fading. The standard runs at 915MHz in the US, an uncommonly used band for connecting wireless devices. As a result, LoRa devices don’t have to compete for airtime with 2.4GHz devices and, instead, enjoy excellent link margins over long distances. LoRa devices can communicate across many miles in open air environments and cut through noisy environments well.
In LoRa networks, wireless sensors and devices connect to the internet or local networks through public base stations. Solution providers can also set up private LoRaWAN gateways in areas with limited cell tower coverage. Often times, it is the end user or solution provider that deploys these private LoRaWAN gateways. Compared to Sigfox, another leading LPWAN protocol, LoRaWAN can transfer larger data loads and support more devices simultaneously.
Providers do not have to pay monthly fees to support wireless devices on a private LoRaWAN network. However, they do need to purchase gateways should they want to expand coverage. Fortunately, it is easy to manage multiple LoRaWAN gateways simultaneously and set up private networks.
There are several leading manufacturers of LoRaWAN gateways:
- Tektelic Communications
- Laird Connectivity
Before purchasing LoRaWAN gateways for your long-range wireless network, be sure to learn about these manufacturers and explore all of your gateway options. Your supplier and gateway choices will depend heavily on your specific Internet of Things (IoT) application.

The KONA Macro IoT Gateway, like the Mega Gateway, is durable and appropriate for outdoor use. However, the device is more compact, lightweight, and is meant more for plug-and-play applications that don’t require significant scalability. For this reason, Macro gateway installations and deployments are less complex overall. The Macro has cellular modem and GPS antennas embedded internally, making the gateway ideal for network sites with small form factors.
The KONA Strand Mount and Strand II IoT Gateways are both designed for rapid cable mount deployments that require a full duplex operation, as well as multiple Rx and Tx channels. Both devices come with geolocation support and rated IP67 enclosures that can withstand extreme temperatures and conditions.
In addition to the gateways described above, Tektelic also offers the Mobile, Micro, and Pico gateways. The KONA Mobile gateway is built for mobile deployments and is capable of Time Division Duplexing. The KONA Micro gateway comes with “Always On” connectivity and an internal 3G/4G modem, which makes it especially valuable for deployments in areas where LoRaWAN coverage is limited for private networks. Finally, the Pico gateway is ideal for homes or small offices that need to integrate LoRa devices directly with existing broadband service.
