Effortlessly deploy your IoT applications in remote areas without being limited by the range of Wi-Fi networks. The Omega2 LTE is the latest addition to the Omega2 family of Linux IoT computers, adding built-in high-speed 4G LTE cellular data connectivity and GNSS global positioning.

Smaller than a credit card, the Omega2 LTE is an all-inclusive, standalone computing device for developing cellular IoT applications. Just add a Nano-SIM card with a data plan, LTE antennas, and power it all up via USB or battery. The Linux network stack makes the switch between Wi-Fi and cellular data seamless to user applications. Take your existing NodeJS or Python IoT project outside the building with minimal effort! Or, use it as a fully-customizable cellular gateway for other Wi-Fi devices, deployed remotely or on the go.

Cellular Network

The Omega2 LTE features an LTE Cat 4 modem that delivers 150 Mbps downlink and 50 Mbps uplink data rates. This same modem features the GNSS Receiver. It enables use cases that are not limited by the range of Wi-Fi networks since the 4G LTE data connection provides internet connectivity as long as there is cellular signal. And the Global Model even supports world-wide connectivity.

Positioning, Available Globally

In addition to the cellular connectivity, the Omega2 LTE features a high-sensitivity, multi-constellation GNSS receiver, capable of retrieving positioning and accurate time data worldwide.

The Omega2 LTE supports all of the common positioning systems:

This further extends the possible use cases to include real-time asset and fleet tracking. Combined with the LTE data connection, it’s easy to build applications that report geoposition, an accurate timestamp, and other data to remote servers.

Even without an LTE data connection, the Omega2 LTE can determine its geoposition and the accurate time, enabling power-saving by locally caching data and turning on the LTE data connection to report data on an interval.

Enabling GNSS and reading the data can be done in just two commands:

# enable gnss data collection
o2lte gnss enable
# read positioning data once satellites lock 
ubus call gps info
# GNSS data:
{
        "age": 0,
        "latitude": "43.727278",
        "longitude": "-79.339722",
        "elevation": "207.9",
        "course": "7.5",
        "speed": "0.0"
}


Wi-Fi Networking

Like all Omega2 family devices, the Omega2 LTE is a whiz at Wi-Fi networking. The Wi-Fi interface can simultaneously host its own Wi-Fi access point and connect to existing Wi-Fi networks. With the addition of an Ethernet Expansion board, the network capabilities can extend to wired networks as well.

The LTE data connection benefits from the flexibility of the network stack as well. The network stack takes care of the low-level configuration of the LTE data connection, making the process easy for the user and seamless for any applications. In addition, the data connection can be shared over the Omega’s Wi-Fi access point with other Wi-Fi enabled devices.

Antennas

To offer flexibility in choosing antennas, the Omega2 LTE features U.FL antenna connectors for connecting two LTE antennas and a GNSS antenna. The Omega2 LTE needs these antennas to connect to cellular networks and GNSS satellites. GNSS is best suited for outdoor use, as it’s not very likely to lock on to any positioning satellites when indoors.

Featuring three U.FL connectors:

1. 4G LTE Main
2. GNSS
3. 4G LTE Diversity

You’ll notice there are two antennas marked 4G: one is the main antenna, and the other is a diversity antenna. The main and diversity antennas work together to improve the quality and reliability of the wireless link. While it is possible to just use the main antenna and get cellular reception, using the diversity antenna as well will increase reception, especially indoors.

We’re offering two antenna options so you can tailor the Omega2 LTE to suit your needs.

3-in-1 Flex Antenna

This Onion-branded antenna sports three distinct antennas in one package: main and diversity 4G LTE antennas that support global cellular frequencies, and a GNSS (GPS & GLONASS) antenna. The antenna is physically flexible and features an adhesive on the bottom, making it a great form-factor for use with enclosures or when space is at a premium. Overall, it’s excellent for portable projects.

Use-cases

The Omega2 LTE has all the hardware and software you need for:

Real-Time Asset Tracking

Use high-level programming languages to quickly write device-side programs for real-time asset tracking or even fleet management. With the GNSS receiver providing location data and accurate time-stamps, and the LTE data connection providing internet connectivity, it’s straightforward to write an application in Python, NodeJS, GoLang, and others to report asset location details to an online server.

Remote Sensing

Expand the reach of your IoT projects and deployments to anywhere that has cellular reception with the Omega2 LTE. Use your favorite programming language to collect data from I²C, one-wire, SPI, digital, or analog sensors, and report it to an online service or API endpoint. Then, add a SIM card to report the data over the cellular network, and you can deploy your cellular IoT sensor device almost effortlessly.

The Omega2 LTE provides a platform for software developers to leverage their experience with Javascript and NodeJS to create IoT hardware. This includes remote sensor nodes, sensor hubs, or remote actuators that take action based on remote commands.

Network Sharing

The Omega2 LTE can share its cellular data connection with other devices. Use one command to enable cellular data sharing over the Omega’s Wi-Fi acces point: {o2lte-graphics-03}

Or, add an Ethernet Expansion board and provide wired internet connectivity over Ethernet:
