Abstract: The study discusses the basic features and functional design of the WiMAX Mobile system, based on the IEEE 802.16e (Release 1.5 Rev. 2.0) standard. The analysis has been made in terms of the ability to use this system to transmit video streams related to the monitoring of large agglomeration areas. Furthermore, the study includes a comparison of the technical parameters of the WiMAX Mobile system with competitive systems such as HSPA+ and UMTS-LTE, which may be used for the transmission of this type of data in the future. An analysis has also been made of selected aspects of data security (in the system approach) connected with the transmission of image data by WiMAX Mobile networks.
1. INTRODUCTION
Video monitoring systems are used to transmit and archive video streams associated with the observation of various types of objects in a selected geographic area.
In the study, special attention will be dedicated to the issue of transmitting this type of data by metropolitan networks based on the WiMAX Mobile system (Worldwide Interoperability for Microwave Access). CCTV monitoring of cities creates extremely wide possibilities for the detection of crimes and offenses at the very moment of their commission.
Studies that have been conducted on the issue clearly show that in areas of cities covered by monitoring, the number of assaults, thefts, or property damage has been significantly decreased. In the case of road monitoring, compliance with traffic rules increases.
Sensor networks can consist of many various types of sensors, for example: seismic, thermal, acoustic, or equipped with a video camera. Such a variety of sensor types results in their ability to perform their functions in various conditions and control many different factors. Wireless Sensor Networks (WSN) are increasingly used in so-called intelligent transport. This is associated, most of all, with the process of traffic monitoring, which is realized by the transmission of video images gained in individual nodes of the network to a central unit, where processing, analysis, and, if necessary, archiving of the image is performed. Furthermore, the current level of technology allows for the automatic speed measurement of cars on roads based on recorded video. (…)
