Immediate treatment of heat stroke is body cooling; currently the preferred method of cooling is evaporation cooling by spraying the patient with cold water or covering them with cold water soaked sheets, and using fans to augment evaporative cooling.
Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards. OFDM has been adopted in the Wi-Fi arena where the standards like 802.11a, 802.11n, 802.11ac and more.
With Frequency Division Multiple Access (FDMA) , different signals are assigned frequency channels. A channel is a frequency. FDMA is a basic technology in the analog Advanced Mobile Phone System (AMPS). With FDMA, each channel can be assigned to only one user at a time.his technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands. Reference: 1.
