Simplex - Set to Set Operation for on Site Communications.
Motorola has a wide range of mobile and handheld products which cover the conventional VHF and UHF frequencies bands.
Generally Simplex frequencies are used when the distance or area of coverage needed is on a specific site or up to 5 to 7km line of site.
The team at T L Parker Ltd can provide radio solutions on simplex (set to set) frequencies ideal for on site communications at the warehouse, factories or farms. Our team of Communications experts will conduct a no obligation free site test to find the most appropriate frequency and equipment for your specific needs, work with Ministry of Commerce to have a frequency allocated to you and you are in business.
Where greater coverage is required other than that available via simplex frequencies, a conventional shared repeater or trunked networks (where available) are the next best low cost options.
Generally exclusive or shared community repeaters are used where trunked systems are not available.
Shared Community repeaters allow several small user too share the cost of installing or renting a local repeater (if available) whilst getting the required local coverage for their business needs.
Exclusive channels allow large local companies to keep their communications cost to a minimum by having a large numbers of units to operate sharing the fixed monthly cost. Generally the cost effective break even point for an exclusive channel is 25 + units.

What is Trunking ?
Trunking is a two way radio communications system which uses state of the art sophisticated computerised technology to allow you to do far more with mobile communications than ever before.
When you invest in Trunked radio communications, a radio channel is automatically and exclusively assigned to you for each of your two way conversations. With today's limited availability for frequency use, Trunked networks allow users to share resources effectively without incurring additional costs.
With the onset of trunking systems, a new dimension has been added to the capabilities of business communications, enabling both organizations and companies to achieve higher levels of efficiency and productivity at lower costs.
With Trunked radio communications, you only pay for the coverage, system and service that suit your individual business requirements.
Trunking provides the ability to send and receive voice and data in a highly efficient manner. It also provides the important benefits of instant access on either local or wide area coverage, flexibility and high degree of confidentiality.
Once you are set up with a fixed monthly access charge per unit, dispatch calls within your network are free !!!!! **
** some network providers may charge for excess airtime usage.
There are two main Trunked dispatch networks available:
