Cellular vs satellite communications for IoT

Cost-effectiveness

Satellite is notoriously expensive because not only is it costly to build, it needs to be sent up into orbit and then constantly maintained. You’ll find the hardware required for cellular tracking is typically less expensive, and monthly data plans can be more affordable too. In contrast, satellite hardware and data plans can be significantly more expensive, making cellular a more budget-friendly option for many businesses.

Coverage and availability

Cellular networks are more readily available worldwide, whereas satellite coverage can have gaps in remote or extreme locations. In fact, cellular generally provides better coverage in urban and suburban areas, where most tracking applications are used. Did you know that satellite signals can be obstructed by buildings, trees, and other obstacles, making them less reliable in certain environments?

Real-time tracking

Cellular networks offer lower latency compared to satellite networks. This low latency enables real-time tracking and communication, which can be crucial for businesses that need to monitor and manage assets, vehicles, or personnel in near real-time.

Device size and power consumption

Tracking devices often have to be small and lightweight by design. Cellular is less demanding on battery life than satellite and will enhance power performance. This is important for applications where size and battery life are critical factors, such as tracking personal devices, vehicles, or wildlife.

Data bandwidth

Cellular networks generally offer higher data bandwidth compared to satellite networks. This can be beneficial for applications that require the transmission of large amounts of data, such as video streaming from a dashcam.

Integration with other services

Cellular connectivity is often easier to integrate with other services, such as web-based tracking platforms, mobile apps, and cloud services. This makes it more convenient for businesses to leverage data and analytics for decision-making.

Regulatory and legal considerations

In some regions, there may be regulatory restrictions on the use of satellite technology for tracking purposes, or there may be additional licensing requirements. Cellular connectivity may be a simpler and more compliant option in such cases.

t42

t42 specialises in wireless systems that track, monitor and protect a variety of assets. Its Helios GPS solution provides automated real-time information on vehicles and drivers, via IoT-enabled devices. t42 required reliable and comprehensive cellular coverage to expand its footprint and support customers globally.

High-performing IoT connectivity was a non-negotiable. Integrating Eseye’s multi-IMSI AnyNet+ eSIM into its Helios system has brought t42 and its customers consistent and fast global IoT connectivity.

As a result, wherever the asset is, t42’s devices instantly connect to the best and most available network, and switch seamlessly to another if connectivity is interrupted, guaranteeing uptime of almost 100%. In addition to tracking and securing vehicles, this enables t42 to offer advanced features such as battery status and safety warnings.

BT Final Mile

BT Final Mile is a smart locker service, introduced by BT with the goal of ensuring that telecoms engineers are no more than 15 minutes’ drive from the parts they need. Its network of intelligent lockers is connected by IoT technology.

Eseye’s in-house IoT device design consultancy brought BT’s vision from idea to proof of concept in weeks, overcoming challenges such as the need for the units to be exceptionally robust. Eseye’s AnyNet+ SIM card is embedded into each locker, delivering 100% cellular connectivity by ensuring it’s connected to the strongest possible network at all times. Engineers are instantly alerted when items arrive at the box, and receive one-time codes to unlock them. The devices also track usage and system functionality, and allow firmware updates to be made over-the-air.

As a result of the initiative engineers spend less time travelling, which has enabled BT to reduce its delivery costs and carbon footprint, as well as provide a better service.
