Summary: FREQUENCY ALLOCATIONS OF THE ISLAMIC REPUBLIC OF IRAN
Summary: The frequency bands 2400-2483.5 MHz and 5725–5870 MHz have been utilized by many applications without need to obtain individual radio license. These frequency bands, which are idetified in ITU RR footnote 5.150 for ISM applications worldwide, are widely used in local area networks (RLAN), municipal area networks (MAN) and wide area networks (WAN). Although these bands are known as ‘license-free,’ however as it is common for other parts of radio frequency spectrum, equipment operating within these frequency bands are subject to fulfill certain regulations and technical specifications. The frequency bands 5350-5150 MHz and 5725-5470 MHz, in addition to above frequency bands, are designated to similar applications, based on ITU RR Resolution 229.
The following decision, are related to the utilization conditions of point-to-point and point-to-area radiocommunication networks which are able to employ spreading spectrum technique with the aim of simplification and clarification of existing regulations, improvement of spectrum utilization efficiency and enabling of more devices to used above frequency bands with acceptable transmission quality.
Summary: “CRA_DEC9000-01” Many applications introduced for low power communicating radio devices in the frequency bands allocated to radiocommunication services and extensive number these devices used for applications such as wideband data transmission, determination, measurement or tracing of objects and environment, daily. The low power characteristics of these devices in combination with interference mitigation techniques either remove interference thread for radiocommunication or make it ignorable after taking a short distance from transmitter. The license-free nature, usefulness, low price, long life, small size and flexibility of low power low interference devices cause wide use of short range devices (SRDs). Although the use of these devices began in the ISM frequency bands but extended to the other frequency bands quickly. In fact, in point of spectrum management SRDs’ radiation is tolerable if their interference to radiocommunications gets vanished in short distance.
Summary: Ultra-wideband technology (UWB) is a new technology for transmission of big amount of data in short distance in an adverse propagation condition. Transmitters in this technology cause a low power radiation within an ultra-wideband bandwidth in a way not to disturb ongoing radiocommunications within utilized spectrum. This technology has been implemented for many applications such as short range high speed communication, radar imaging, medical imaging, detection the movement or location of persons or objects, vehicular radars and intelligent transportation. Due to capability of UWB technology to deliver high data rates with small energy consumption for multiple clients, it is more preferred compared to other indoor technologies such as WiFi and Bluetooth. For the near future, expected that the mass produced devices such as personal computers, laptops, cameras, vehicles, mobile phones, TVs, and audio systems would widely use UWB technology for high speed data communication among themselves.
