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 media refers to inflammation of the middle ear. Acute otitis media occurs when a cold, allergy, or upper respiratory infection, and the presence of bacteria or viruses lead to the accumulation of pus and mucus behind the eardrum, blocking the Eustachian tube. This causes earache and swelling. When fluid forms in the middle ear, the condition is known as otitis media with effusion.. This occurs in a recovering ear infection or when one is about to occur. Fluid can remain in the ear for weeks to many months.
