SecIndGroup.com question of the day: What is UHF?

Episode 7: “Hey Maarten, what is UHF and how do we use it in security?”

Maarten Mijwaart from SecIndGroup.com tries answering questions that are relevant to the security industry.

This week’s question: What is UHF?

UHF is an acronym for Ultra High Frequency. It refers to the bandwidth between 300 MHz and 3000 MHz. In security we most often use approximately 900 MHz.

UHF was first used in logistics as an alternative to barcodes (read multiple tags on objects remotely, for example for inventory management). The GS1 EPC Gen II standard allows that a reader from vendor A will read tags from vendor B. Version 2 of the standard adds encryption to the communication to support tag authentication.

There are many suppliers of UHF readers. Each reader has it’s own features and characteristics (antenne orientation, interfaces, finetuning, etc.), so make sure you are informed well.

UHF tags exist in many different shapes and sizes. Windshield tags, metal tags, cards, etc. No wonder UHF is popular and used in all kinds of applications to identify people, vehicles or other objects.

Make sure the reader and tags you select for your application are tuned for the right region. Also make sure that tags are programmed in a format and range that fits with your management system or access control solution.
