Simplex radio communications is where a single frequency is used for the TX and RX operation. A radio transmits on a frequency and the receiving radios receive on that frequency and replies on the same frequency. This is Radio to Radio operations and requires no infrastructure for communications, this is the simplest form of two-way radio comms.
– Radio to Radio
– 1 Frequency required
– No infrastructure required
– Cost effective solution
– Short range of coverage
– Used for small to medium areas of operation
To achieve a greater range from a Two-Way radio solution a repeater installed at a high or central point is used. This can dramatically improve the range and overcome structural and geographical obstacles. When using a repeater 2 frequencies are required and the repeater is receiving and transmitting at the same time. This process is call Duplex mode of operation.
– Radio to Infrastructure to Radio
– 2 Frequencies required
– Repeater and antenna required
– Increased cost for solution
– Large areas of coverage
– Used for larger buildings and areas of operation
A Wide Area Network is a Two-Way radio system of linked repeaters on different sites to prove even great radio signal coverage over a larger geographical area or throughout large complex building and work sites. The sites are linked via a Radio link (RF), fibre optics or IP linking and can provide coverage over large cities, rural areas or even entire countries.
– Radio to Infrastructure to Radio
– Multiple frequencies used
– Repeaters, linking and Antennas used
– Local installation or Subscription based
– Very large areas or building complexes
– Used for multiple areas of operation
Push to Talk-Over-Cellular (PoC) is a service that provides Two-Way radio style PTT one-to-one or one-to-many instant communications via the mobile phone cellular networks and Wi-Fi solutions. Voice calling and data functions using the PoC application installed on a PoC Two-Way Radio, on any mobile phone and via PC based application.
– Portable and Vehicle radios, Phone/PC Apps
– GPS tracking, Job management Software
– No infrastructure required
– SIM, Subscription based
– Nation wide coverage
– Used widely for Fleet operations
UHF CB (Citizen Band) radio is a Two-Way product for none commercial operations with no ongoing fees. UHF CB is free to use anywhere in Australia for recreational and emergency communications. Consisting of 80 channels with a mix of simplex and repeater operation (community repeaters). CB is great for on the road between vehicles, in your 4×4 and when hiking in the bush.
– Portable and Vehicle mount radios
– Simplex and Duplex Channels
– Up to 5 Watt legal limit
– Licence Free
– Ideal for recreational 4×4, Hiking, road trips etc
– Vehicle antenna options
Land Mobile Radio is the commercial allocation of the frequency spectrum used by many businesses and industries throughout the world . LMR is their primary means of communication and provide emergency communications for evacuations. Commercial LMR Radios are typically available in the VHF and UHF frequency bands and governed via the ACMA in Australia.
– Portable, Mobile, Data and Infrastructure
– Licensed Frequencies via ACMA
– Required for all transmitters
– Annual Subscription and Application fees
– Commercial Two-Way radio operation
– Used by all radios in LMR bands
The GRN, Government Radio Network provides vital radio communications for our emergency and public services. GRN coverage through-out buildings and public spaces is required to enable emergency services to communicate effectively during site visits. We can provide analysis of the GRN coverage at a location and assist in any GRN solution.
– GRN Site Surveys
– GRN Coverage Reports
– Approved Terminals
– Re-broadcast solution
– Targeted signal options
– GRN Documentation
A VHF Marine Radio uses Very High Frequency transmission to broadcast voice for communication between a vessel and a transceiver, which could be another boat, a handheld VHF receiver, or a station on land. Marine VHF radio equipment is installed on all large ships and most seagoing small craft for marine navigation and traffic control, emergency situation and communicating with harbours, locks, bridges and marinas.
– Portables and vessel mount radios
– Operator requires licence
– Allocated preprogrammed channels
– Required by boats on open water
– Short range communications
– Used by commercial and recreational vessels
