Three Basic Modes Of Signal Communication And Mobile Health Applications

Improved Essays
Cellular networks are a type of wireless WAN. Various technologies are utilized in cellular networks but there are only three basic modes of signal communications. These are simplex, half duplex and full duplex. In simplex transmissions the signal goes in only one direction and this type is usually seen in television and radio stations. Half duplex signaling is bi-directional but each signal has to wait its turn because only one can travel at a time. Examples of half duplex are the push-to-talk Nextel phones and standard walkie-talkies. The third communication mode that allows for simultaneous bi-directional signal transfer is known as full duplex. Cellular technologies utilize full duplex (Gow & Smith, 2006). The purpose a cellular network …show more content…
Mobile medical applications are on the rise and they include applications for the management of chronic diseases, iPrescribe, remote access to medical records and lab results, and diagnosing medical conditions over smartphone applications (Kabachinski, 2011).

A base station for microwaves is line of sight (LOS) dependent and two stations can connect up to 48km if they are in LOS (Cowley, 2012). The further a microwave signal travels between relays the lower the possible data rate (Cowley, 2012). Microwave transmissions utilize an orthogonal frequency division multiplexing (OFDM) technique. The OFDM technique basically splits the high-speed data into multiple lower-speed signals and places them in subcarriers, this creates an efficient use of the radio spectrum and allows the microwave signal to travel with very little interference (Cowley, 2012). Other benefits of using WiMax technology are the high bandwidth it supports as well as its security, both are vital in healthcare

    A relay is not equipped with satellite and terrestrial antennas but routes tree nodes' video traffic using the WiFi (802.11n) link from source nodes. If nodes communicate over WiFi (802.11n) then connectivity is formed on orthogonal channel using pair of 802.11n routers. However,if nodes communicate over LTE, it share resources over a single channel.…

    In CDMA networks different nodes can transmit simultaneously and their respective receivers correctly receive a sender’s encoded data in spite of interfering transmissions by other nodes. (Kurose 449) CDMA was first used during World War II by English allies to stop German attempts at jamming transmissions by transmitting over several frequencies, making it difficult for the Germans to pick up the complete signal. The company Qualcomm created communication chips for CDMA technology, and were the first to commercialize it. CDMA is widely used in cellular networks. CDMA main competitor cellular networks is GSM (Global System for Mobile communication).…

    Introduction Healthcare providers in the rural areas of the U.S., like the rest of the nation, are dependent on evidenced based practice literature to supplement their practice. The cost to provide the “brick and mortar” type access to nationalized databanks is an added expense to the restricted budget present is many communities. According to Carter-Templeton & Wu, having access and skill to utilized mobile medical applications (MMA) on personal devices makes the required information easily accessible. Information and usability of the MMAs can affect the outcome of not only the providers but also their clients as well (Biediger-Friedman, Crixell, Silva, Markides & Smith, 2016.)
