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.
Otitis externa, also known as acute external otitis, swimmer's ear, or tropical ear is an infection of the skin covering the outer ear canal that leads to the ear drum, called the tympanic membrane.igns and symptoms may include: Acute diffuse otitis externa-the swelling (inflammation) of the ear canal is more extensive. A rash can extend to the pinna (outer ear) and tympanic membrane (ear drum). Acute in this text means the otitis lasts no more than three weeks.
