How Antennas Are Used in the Transportation Industry

The transportation industry continues to be strong. Without trucks, air, rail, and marine vessels, much of what we use daily wouldn’t be available. It’s so strong that, since 1979, it has seen more growth cycles than drops.

One of the important features of the transportation industry is not the capacity of the carriers or the length they travel. It’s the use of antennas. These play some very important roles in all forms of the sector. Here’s how antennas are used in the transportation industry.

Two-way communication
While CB radios aren’t as popular as they once were in the 1970s, these two-way communication devices are still widely used in trucks and marine vessels.They allow transport workers to communicate with their base stations and others on the road or at sea. In addition, these citizens band devices allow users to report emergencies and weather/traffic conditions on dedicated channels.

GPS tracking
The goal of transportation services is to get their products safely delivered on time. To monitor this, companies in this sector use GPS tracking. An antenna is attached to the vehicle along with a transponder. With corresponding software, dispatchers follow the process of vehicles as they journey to their destination.

WIFI/Cellular access
Those who transport goods can’t rely on sporadic WIFI signals that float in and out depending where they are. This is especially true for air and sea vessels. Thus, they require the installation of WIFI and/or cellular antennas.

These work with today’s standards. So, cellular antennas can operate with 3G/4G networks while WIFI models have bandwidth capacities of 2.4GHz, 5GHz, or both.

For these to properly work they require the same qualifications as a standard radio antenna. They need a clear line of site, an elevated presence on the vehicle, and proper access to the signal. So, for example, the WIFI or cellular antenna would be placed on the roof of a semi-truck so the signal isn’t blocked by other vehicles.

Safety
The above-mentioned uses of antennas in the transportation industry can be consolidated into their most important aspect — safety. For instance, rail transportation relies on antennas to ensure switches are properly engaged to avoid collision. In addition, using satellite imagery, they can alert engineers if there are potential climate issues that may require them to slow their speeds.

Overall, antennas are extremely important for the transportation sector. They keep drivers connected to the rest of the world while alerting them to potential difficulties. In addition, they can help track the whereabouts of company vehicles to maintain schedules. They are multi-purpose communication tools that keep the transportation sector on the road, in the sea, or in the air.
