The FCC has announced that narrowbanding 700 MHz networks by 2017 is no longer mandated. In this article, Tait Public Safety Solutions Manager Dr. Russell Watson looks at who will be affected, and what the implications are.
Towards the end of 2014, the FCC announced that the 2017 narrowbanding implementation deadline was no longer viable, or indeed necessary. This decision was preceded by FCC granting a number of waivers to entities who had argued variously that:
- they had no spectral congestion,
- the regulation artificially shortens the life of their existing... Continue Reading
If you have never been involved in renovating your own house, you almost certainly know someone who has. It is a major logistical exercise in planning, perseverance, and above all, patience! Mostly, you will end up with what you want, but how often do you think “I wish I had shifted that wall/put in more storage/added another bathroom”?
There are so many things to decide, and only one chance to get it all right. And for most people, you will be carrying on your domestic “business as usual” amongst the chaos of upgrading your home.
Upgrading your radio system is a bit like... Continue Reading

Last week we introduced the new P25 Best Practice guides and website. Today we’ll dive a bit deeper to take a look at the first guide: First Steps to your P25 System.
I recently drove to a friend’s house and attempted a short cut. Unfortunately, I started by making the wrong turn. I ended up in a place I was unfamiliar with, but kept guessing the general direction of my destination. After a while, I literally found myself on the complete opposite side of town.
So much for finding a short cut.
If your... Continue Reading
In this part of the P25 radio terminology, we cover multicast IP address, P25 gateways, QoS and other important P25 terms.
Previous parts of the P25 glossary: Part 1 (A to C) and Part 2 (D to K).
Local Area Network
Link Data Unit. Voice calls are sent over the CAI as a series of LDUs. Continue Reading
Previously, we covered the essential P25 terms from A to C. Continuing our series on must-know P25 radio terms, this week we bring you the second installment.
The data gateway is a function carried out in a Tait P25 base station or P25 console gateway operating in a TaitNet P25 conventional network. It provides a gateway between P25 radios and a data server and requires the Conventional Packet Data Services feature license. Continue Reading

Over the last few weeks, we have covered P25 radio communications in great detail, including An Introduction to P25, The P25 Standard and Compliance and Benefits of P25. As a recap and to tie everything in together, over the next few weeks we’ll present a glossary of all the P25 radio-related terms that you need to know.
AES (Advanced Encryption Standard) is an encryption algorithm that uses keys of 256 bits.
The Algorithm ID is an identifier that specifies an encryption algorithm (for example, DES or AES). Continue Reading
GSM cellphone technology, APCO P25 in United States public safety, TETRA in Europe and DMR worldwide are examples of successful digital standards. Successful standards bring real advantages. When vendors work to agreed standards, those managing radio systems have a choice of supplier which can bring down prices, and improve quality. Customers are not at risk of being unable to source products for replacement or expansion through the demise of a sole supplier.
To properly qualify, a standard needs to be non-proprietary, so not under the control of one vendor. It... Continue Reading
What is the all the fuss about P25? What makes P25 so special? What benefits do P25 radio communication systems have over analog radio systems?
In this series of posts on the benefits of P25, we answer how P25 can ensure better reliability, clarity, control and customization of your radio network. Continue Reading
A basic requirement for Phase 1 P25 digital radio equipment is backwards compatibility with standard analog FM radios. This supports an orderly migration into mixed analog and digital systems, enabling users to gradually trade out radios and infrastructure equipment.
Agencies can invest in the latest P25 technology and operate it initially in analog mode with the assurance that there is a clear migration path to the future. Continue Reading
