RF Performance Advantage

July 2, 2015

What is it?
The RF performance of all Base Station, Mobile or Portable radios is quantified in a set of specifications given in deciBels (dB). One set of RF performance specifications describes the Transmitter performance, another describes the Receiver performance. For some RF performance specifications, a larger number is better; and for others, a smaller number is best. There are minimum acceptable RF performance specifications prescribed by regulatory authorities such as ETSI (Europe) and FCC (USA). Meeting these is mandatory.

Some RF performance specifications are more... Continue Reading

What is a radio wave? | Radio Academy

June 30, 2015

If the term “Electromagnetic Spectrum” is not familiar to you, the lesson Introduction to Radio Communication Principles: What is a radio wave? has all the information you need to understand radio waves.

The lesson is free to view and walks through everything there is to know about radio waves such as how energy changes waves, their frequency, how their length affects the way in which they are heard and an explanation of the electromagnetic spectrum.

Learn more about the basics of radiowaves by watching the video above and read the accompanying What is a Radio Wave? lesson.... Continue Reading

Advantages of DMR versus dPMR / NXDN / NEXEDGE

June 4, 2015

What is dPMR?

  • dPMR is an ETSI standardised minimal cost digital radio solution.
  • dPMR standards (TS102 490 and TS102 658) were published in 2007 – after DMR. There are 2 tiers specified – Tier 2, modes 2 & 3 are relevant to professional users.
  • dPMR operates in 6.25kHz channels. Tier2, Mode2 is conventional; Tier2, Mode3 is trunked.
  • NXDN is based on dPMR but is incompatible with it. NexEdge is also derived from dPMR.

What is DMR ?

  • DMR is an ETSI standardized low cost, low complexity, professional digital radio solution designed to migrate analog FM radio... Continue Reading

Trunked vs Conventional Radio Networks

April 21, 2015

This post looks at the fundamental differences between trunked and conventional radio networks.
What are the top level differences between Trunked and Conventional?
In a trunked system:

  • The channels are assigned to the user automatically by the system
  • The call set up time is several hundred milliseconds
  • One channel per site must be used as a control channel.

In an analog conventional system:

  • The user manually selects the channels
  • The call set up time is almost instantaneous
  • No control channels are needed, so all channels are available to the user

Analog FM can... Continue Reading

EA Networks are Improving their Grid Visibility with Tait GridLink

February 3, 2015

Last week we wrote the article Introducing Tait GridLink: The economically intelligent choice for distribution automation.

EA Networks are currently trialling six Gridlink terminals to improve their network visibility. EA Networks owns and operates the electricity distribution network and an advanced fiber-optic communications network for the mid-Canterbury region, delivering power to approximately 17,450 consumers through almost 1,864 miles (3,000km) of distribution lines. you can read the full case study here

Tait helps solve Jim Wells County’s communications woes

May 15, 2014

When Jim Wells County, an expansive county in South Texas and home to more than 40,000 citizens, first met us, they faced the threat of an outdated analog radio communications system that was unreliable and endangering the lives of the County’s law enforcement and emergency responders.

We committed to understanding the issues the County faced – a unique geography, limited funds, dated equipment and a tight schedule and delivered a three-site hybrid P25 digital and analog simulcast system. The Tait solution is now helping the County’s 400 law enforcement and emergency response agencies operate more effectively and safely. Continue Reading

DMR versus dPMR comparison — Part 1

January 23, 2014

Last week’s post on open digital radio standards reveals that the major difference between DMR and dPMR is the choice of multiple access scheme. DMR uses 2-slot TDMA to achieve two communication paths per 12.5kHz channel, whereas dPMR uses FDMA to divide the 12.5kHz channel in to two 6.25kHz sub-channels.

Therefore, the comparison of these two systems very much comes down to understanding the relative advantages and disadvantages of TDMA versus FDMA. Continue Reading
