The Evolution and Importance of Cellular-Enabled GPS Tracking Devices

In the age of digital transformation, the ability to track assets in real-time has become paramount. From personal items like pets to business assets such as fleet vehicles, cellular-enabled GPS tracking devices have emerged as the go-to solution. Leading this innovation is Simplex Wireless, but understanding the landscape requires a deeper dive into the world of cellular IoT connectivity.

The Cellular IoT Landscape in GPS Tracking

The buzz around 5G has been deafening, promising super-fast speeds, enhanced responsiveness, and ultra-low latency. But what does this mean for the 4G GPS tracking devices many have invested in?

GPS tracking devices, whether 4G or 5G, are essentially sensors. They gather data – location, temperature, on/off status, and more. However, these devices need a communication medium to relay this data. This is where Cellular IoT comes into play. It leverages existing mobile networks, covering a staggering 95% of the global population with at least a basic 2G network.

Interestingly, most IoT and GPS devices don’t need the high-speed bandwidth that consumer cellular devices demand. They transmit smaller packets of data, like the daily GPS coordinates of an asset. This is where technologies like LTE-M and NB-IoT, part of the 4G-LTE specification introduced in 2016, become crucial. These Cellular IoT networks are low-power, wide-area networks (LPWANs) that offer long battery life, enhanced coverage, and affordable connectivity options.

LTE-M vs. NB-IoT: The Cellular IoT Titans

Both LTE-M and NB-IoT are pivotal for IoT and Machine to Machine (M2M) applications. But how do they differ?

• Bandwidth: NB-IoT operates on a narrow bandwidth (200kHz), while LTE-M uses a much broader 1.4GHz.
• Data Transfer Rate: NB-IoT can transfer data at around 250kb per second, whereas LTE-M is about four times faster, reaching up to 1Mbps.
• Cellular Tower Handover: LTE-M supports this feature, ensuring continuous connection even when moving between cellular towers. NB-IoT lacks this, dropping the connection if a device moves out of range.
• Power Consumption: Both networks are energy-efficient, but their data transfer rates can influence the power used during data uploads.

For tracking applications, NB-IoT is ideal for stationary assets reporting infrequently, like checking if a fire alarm is powered. Its devices are simpler and often more cost-effective. LTE-M, on the other hand, is perfect for tracking moving assets like vehicles, requiring more frequent data updates.
