AGV Users Navigating to Narrow Band Communications

The use of the wideband communications systems has led to overcrowding in the UHF and VHF bands.

The use of the wideband communications systems has led to overcrowding in the UHF and VHF bands. FM radio broadcasting shares the same space with television, cordless phones and land mobile stations that control automated guided vehicles (AGVs). That’s why in 2011, the FCC released a public notice stating that all private land mobile radio licensees operating in the 150-174 MHz and 421-512 MHz VHF and UHF frequency bands must change to narrowband technology by January 1, 2013. The new guideline requires narrowband systems to use 12.5 kHz or less bandwidth.

Penalties for non-compliance may include license revocation, and/or monetary forfeitures of up to $16,000 for each violation or each day of a continuing violation, as well as up to $112,500 for any single act or failure to act.

To help industrial AGV users comply with the FCC’s notice, Daifuku Webb Holding Company and its subsidiary Jervis B. Webb Company are transitioning customers to narrowband frequencies. The process begins with an on-site evaluation to determine the best way to meet both the FCC mandated changes, as well ensure the long-term viability of the AGV systems. A schedule is then developed to transition customers in the most effective way possible without compromising production.
