When medical technology, communication, and computers were developed and put into practice in the treatment and follow-up of remote health care patients, the difficulty of communicating with the medical team or patients was due to bandwidth limitations. Sending a significant volume of data between medical personnel and patients, as well as power usage, is not permitted. Wireless sensors use a direct spread spectrum based on CDMA, especially mobile wireless third generation with a wide bandwidth

The wireless sensor network decreases the power consumption of the transmitter sensor and the receiver sensor by using binary transmission and multipath. The accuracy of the measurement depends on the bandwidth of the unit to calculate the time of arrival (TOA). The TOA forecasts come and go together to pass them to the receiver because of the delay of the MPC and the reduction of replicas of the initial signal. The diffusion time caused by the moving signal through barriers, adding a positive bias to the TOA.
