  • Mhz As a Primary User
    Response to Ofcom Consultation Q1. What future uses might this spectrum support? The availability of this spectrum is a rare opportunity. As such, the benefits should be made to the general public, as well the business stakeholders. 1. Amateur Radio:The UK Amateur Radio service is allocated the 2m band from 144.000 to 146.000 MHz as a Primary User. In comparison, the USA has an allocation from 144.000 through to 148.000 MHz. An expansion of this band by 0.5 – 1 MHz immediately above 146.000 MHz will be beneficial to the amateur radio community. 2. VHF Citizens' Band service: The UK only CB Service at 934 MHz was withdrawn in 1998, with the loss of 20 channels to GSM 900 Mobile operators. This is an opportunity to re-introduce a 20 channel CB service, at a frequency range which does not have the propagation characteristics of the 27 MHz band. An allocation at VHF will allow practical antenna lengths to be used in vehicles and buildings. In comparison, ACMA (Ofcom's counterpart in Australia) has sanctioned the use of a 77 Channel “UHF CB” service at around 476 – 477 MHz. 3. Simple UK (Business Radio): The business radio Simple UK licence permits 15 spot frequencies to be used at a 12.5 kHz bandwidth. The addition of more frequencies for this licence type will ease congestion. 4. A “personal use” radio service: There are a number of licensable and licence-free radio services available for individuals. This include PMR446 (licence-free) and the licensable Business Radio (Simple UK), as well as CB Radio on 27 MHz and a number of low-power allocations.

  • Airband Radio Operator Certificate Manual
    Airband Radio Operator Certificate Manual 1- Version: January 2012 About the airband radio operator license Very high frequency (VHF) airband radios are becoming more common as a tool for aircraft pilots to identify the location and intention of other aircraft in their vicinity (for VHF use at non-towered aerodromes see Civil Aviation Advisory Publication 166-1(0) and 166-2(0)).i In some classes of airspace the use of VHF airband radios is mandatory. Using a VHF airband radio requires a license endorsement. To obtain a VHF airband radio operators license you must satisfactorily (80% pass mark) complete both written and practical exams. This manual provides you with information regarding VHF airband radio use in Australia for the satisfactory completion of the written VHF airband radio operator examination. Radio communications in Australian are controlled by the Australian Communications and Media Authority ( www.acma.gov.au ). About the airband Airband radios transmit and receive a radio frequency. Radios are set to transmit and receive on specific frequencies across a band of frequencies. The radio waves that are transmitted and received are base on wavelengths and amplitudes. A cycle is one complete wave action. The frequency, measured in Hertz, is the number of cycles passing a given point in one second. One cycle per second = 1 Hertz (Hz) 1,000 Hz = 1 kilohertz (KHz) 1,000 KHz = 1 megahertz (MHz) 1,000 MHz = 1 gigahertz (GHz) The wavelength is the length of one cycle. The height of the peak or trough from the centreline is called the amplitude ; the greater the amplitude, the stronger the signal.

  • University of Southern Queensland Faculty of Engineering & Surveying
    University of Southern Queensland Faculty of Engineering & Surveying Telemetry and Communication Systems for Irrigation Management A dissertation submitted by Alison McCarthy in fulfilment of the requirements of ENG4111/2 Research Project towards the degree of Bachelor of Mechatronic Engineering Submitted: November, 2006 Abstract The development of wireless communication systems for agricultural and irrigation ap- plications has enabled farm managers to access real-time data from in-field sensors to improve on-farm operations. Recent research into wireless sensor networks for agri- culture has focussed on reducing the power consumption and manual configuration of the nodes by the end-user, while commercial wireless sensor networks use short-range transceivers such as Zigbee or long-range transceivers such as UHF citizen band radio. However, the research wireless sensor networks often experienced reduced reliability under field conditions. Therefore, this project aims to design a telemetry system with a focus on reliability under field conditions. UHF citizen band radio was investigated as a candidate wireless transmission medium over which audio tones, modulated with serial data, were transmitted. The modulation technique used was frequency modulation, and was implemented using integrated circuit modems. A wireless network was designed with: a polling medium access method; star topology; error handling using repetition and cyclic redundancy codes; and robust protocol. The developed telemetry system was tested under field conditions, such as in the pres- ence of crop canopy and irrigation water, and near power lines which potentially cause noise in telemetry signals. Data delivery rates of 100% were achieved using 0.5 W radios transmitting at 1200 baud for 2 km, which satisfied all the telemetry system requirements.

    CODE OF PRACTICE FOR THE PAIRING OF VHF AERONAUTICAL STATIONS TO VHF OR UHF LAND MOBILE RADIOS ‘Best practice’ recommendations for interconnection of services between VHF Airband (AB) and Land Mobile Radio (LMR) systems Australian Radio Communications Industry Association Inc. (ARCIA) Unit 9 – 21 Huntingdale Road, Burwood, Vic 3125 Australia www.arcia.org.au - @ARCIAorg – [email protected] “© This document is protected by Copyright legislation and may only be reproduced in its entirety and without amendment or alteration.” CODE OF PRACTICE FOR PAIRING OF VHF AIRBAND AND UHF/VHF RADIOS Code of Practice for the pairing of VHF Aeronautical radios to VHF or UHF Land Mobile Radios. This code of practice has been developed by the Australian Radio Communications Industry Association (ARCIA), both the Australian Communications and Media Authority (ACMA) and Air Services Australia (ASA) were consulted during the development of the code. The code is designed to provide information for regulators, airlines and communication industry members on a standard interface format for interconnection of radios. Guiding Principles VHF Aeronautical (AB) frequencies and networks are a critical part of aviation networks in Australia. Protection of these networks in particular from interference is paramount for the safe operations of Aeronautical networks. This code of conduct is intended to maintain the expected protection of VHF Aeronautical frequencies and networks in Australia. All Radio Frequency (RF) equipment has the potential to cause interference and this Code of Conduct serves to highlight suitable standards for all RF equipment used in airports. The Code of Conduct does NOT permit (under normal operational circumstances) equipment to be connected in this format for other than provision of ‘Ground service facilities’ at any airport, it must not be used for any form of Flight Operations.
