FAQ:


What is Ultra high Frequency?
Ultra high frequency (UHF) refers to the band of electromagnetic radiation with a radio frequency range between 300 MHz and 3 GHz (3000 MHz). This band is also known as the decimeter band, with a wavelength ranging from 1 m to 1 dm. The UHF radiations are least affected by environmental factors, that is why they are most commonly used for TV and radio transmission and channel broadcasting. They have strong directivity, but, at the same time, the receiving error increases.

OPPIOT explains Ultra High Frequency

Ultra high frequency is widely used for data transmission owing to its short wavelength and high frequency. Since the size of a reception antenna is directly proportional to the size of the waves, the antennas for UHF are short and stout. The higher the frequency band is, the less conspicuous the antenna size would be. The broadcast range (also called line of sight) of UHF is shorter than that of VHF, that is why boosters are used after a few hundred kilometers. UHF is used by cordless and two-way navigation, wireless local area networks, and communication, radio and security systems. UHF radars are said to be effective at tracking stealth fighters but not stealth bombers.

Uses of Ultra high Frequency
UHF spectrum is used for an enormous variety of purposes, including: mobile phones (PCS etc.), television broadcasters, GPS satellites and devices, satellite radio (XM and Sirius), cordless phones, wireless networking, ham radio operators, Bluetooth devices and some RFID chips.

Why UHF anti-metal tag?
Mounting or embedding RFID tags on metal is a tricky proposition for the uninformed, and the informed for that matter. Metal surfaces reflect energy emitted from RFID readers and create interference for RFID tag antennas, which means the tag isn’t able to receive power and transmit information; however, specific RFID tags will work around metal surfaces. RFID companies have patented technology that allows RFID to work when attached to metal surfaces and even embedded within metal products. As long as you choose the correct RFID equipment for your situation and application, you won’t need to worry about interference from metal.

What industries are using UHF anti-metal tag?

RFID on metal tags are perfect for asset and tool tracking in medical devices for healthcare, laptops & servers in IT (information technology), industrial manufacturing, oil & gas pipelines, vehicle tracking identification, and many other industry verticals. With the recent developments in RFID technology, the possible applications of metal mount RFID tags are expansive in scope.

OPPIOT RFID Tags Beat the Heat!
Need to track assets or machines exposed to extreme heat, high pressure or corrosive chemicals? OPPIOT, and only OPPIOT, has the perfect tag for you.

Many industries process assets, products or materials at elevated temperatures using carriers or containers for transportation purposes. Frequently being able to reliably and uniquely identify and track the asset or container is highly advantageous, generating efficiency and compliance benefits.

OPPIOT found the marketplace was in great need of a tag that could survive repeated exposures in high temperature settings such as automotive paint booths, medical autoclave sterilization and manufacturing operations. The only available tags on the market were, and continue to be, too large and bulky for most use cases, too expensive for large deployments and generally unreliable with an inconsistent resistance to high heat.

OPPIOT provides a complete family of tags designed specifically for high temperature environments reaching 235°C. These products address the critical needs of customers with their combination of a small form factor, read range up to 4m and high temperature survivability – all at a very competitive price point
