DESIGN AND PERFORMANCE EVALUATION OF AN IEEE 802.11AX SYSTEM FOR CATHLAB WITH HIGH QOS
| Resumo: | Wireless network communications are increasingly common in our society. The high number of devices leads to very dense scenarios with high interference, leading to a degradation in the Quality of Service (QoS) of their communication, which is extremely difficult to achieve with current communication standards. Wi-Fi 6 or IEEE 802.11ax was developed to overcome these difficulties, bringing new developments in wireless network communications, increasing transmission efficiency and improving throughput for these communications. With the increase in devices communicating over wireless networks, medical applications are being considered to make this transition, aiding doctors’ dayto- day operations and facilitating cleaning. A Cath Lab currently needs to carry out examinations using video capture and transmission. The cable connecting the devices has to be sterilized and cleaned between patients. To simplify the use of these instruments, a transition to wireless communication is being studied. This dissertation analyzes the performance of a IEEE 802.11ax wireless network using the Network Simulator 3 version 3.34 (ns-3.34). It studies an interference scenario where the Cath Lab WiFi network connecting the devices coexists with a nearby interfering IEEE 802.11ax network, showing that the Cath Lab QoS is sustained as long as the interfering load is limited and a minimum distance to the Cath Lab AP is satisfied. |
