UHF RFID. The UHF frequency band covers the range from 300 MHz to 3 GHz. Systems complying with the UHF Gen2 standard for RFID use the 860 to 960 MHz band. While there is some variance in frequency from region to region, UHF Gen2 RFID systems in most countries operate between 900 and 915 MHz.The read range of passive UHF systems can be as long as 12 m, and UHF RFID has a faster data transfer rate than LF or HF.hile there is some variance in frequency from region to region, UHF Gen2 RFID systems in most countries operate between 900 and 915 MHz.

Malignant external otitis (MEO) is an infection that affects the external auditory canal and temporal bone. The causative organism is usually Pseudomonas aeruginosa, and the disease commonly manifests in elderly patients with diabetes.
A middle ear infection, also called otitis media, is a common, often painful, type of ear infection that occurs behind the eardrum. Middle ear infections are caused by bacteria or viruses. A middle ear infection can interfere with the normal process of hearing and result in ear pain, hearing impairment, and other symptoms. People of all ages can get a middle ear infection, but it is more common in infants and young children up until the age of three.
