Electromagnetic field strength simulator (ELMO) for RF hazard assessment. There is significant community fear related to exposure to mobile telephone radiation. The computer program ELMO will be designed to accept information about all RF transmitters in the vicinity of cellular telephone towers from an existing database, and to calculate the total field strength. This will allow hazard assessment for both RF technicians working on the tower and adjacent residents.
Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and ....Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and an increase of interference. The aim of this project is to demonstrate an alternative method of maintaining good quality communication link. The proposed method employs a smart antenna system to mitigate adverse effects of multi-path and interference.Read moreRead less
Modelling Human-Body Effects on Indoor Multiple-Input Multiple-Output Channels for Broadband Wireless Systems. Multiple-Input Multiple-Output (MIMO) technologies use a number of antennas to send multiple signals as a way to significantly increase the speed, range and reliability of a wireless network. The upcoming IEEE 802.11n standard, which includes MIMO in its specifications, will offer up to eight times the coverage and up to six times the speed of currently available IEEE 802.11 products. T ....Modelling Human-Body Effects on Indoor Multiple-Input Multiple-Output Channels for Broadband Wireless Systems. Multiple-Input Multiple-Output (MIMO) technologies use a number of antennas to send multiple signals as a way to significantly increase the speed, range and reliability of a wireless network. The upcoming IEEE 802.11n standard, which includes MIMO in its specifications, will offer up to eight times the coverage and up to six times the speed of currently available IEEE 802.11 products. Through comprehensive measurement campaigns, this project will characterise the time-varying human body effect on indoor MIMO systems in populated environments, such as busy industrial and commercial buildings. Results will have a direct impact on future wireless applications, and are valuable from both scientific and economy-enhancement viewpoints.Read moreRead less
