Cellular service providers are shutting down their 3G networks this year, a shift that could impact legacy wireless systems that some fleets are still using, experts said.

Federal trucking regulators are warning truckers that mobile carriers are shutting down their 3G networks as early as next year to make room for more advanced network services, including 5G.

Strong freight demand helped less-than-truckload carrier Saia Inc. report record third-quarter revenue, profits and operating ratio.

While the timing is expected to vary, many wireless cellular providers plan to phase out or “sunset” their remaining 2G and existing 3G networks early next year, according to the Federal Communications Commission.

Although no devices have been approved for drivers, Canada’s electronic logging device mandate is less than a month away and fleets should prepare accordingly.

The federal electronic logging device mandate has leveled the playing field among motor carriers and reduced driver hours-of-service violations, but it may still be too early to determine how ELDs have affected safety on the nation’s roadways, industry experts said.

Before the federal government’s revised hours-of-service rules went into effect Sept. 29, suppliers of electronic logging devices were busy updating their software.

The owner of a Rhode Island-based trucking company has admitted to falsifying service records for approximately 20 drivers.

Trucking companies that are becoming more technological are at risk of increased vulnerability, but there are steps they can take to mitigate such threats.

The FBI issued a cautionary notice warning truckers that cyber criminals could target electronic logging device vulnerabilities as a means of seizing business information, but industry experts note that hackers have as yet not found a way to crack into ELD data.
