By protocol
Digital two-way radios — DMR
DMR is a protocol, not a grade. It changes what a fleet can be asked to do, and it changes what happens to the part of the fleet that stays analog.
Collections
The same catalogue, sliced by the question you are asking
A buyer rarely searches for "portables". They search for a protocol, a rating or a band. These pages take the whole catalogue and cut it the other way, so the answer is a set of identifiers rather than a category.
A category is not a collection
| Category | Collection | |
|---|---|---|
| Answers | What kinds of hardware exist | Which identifiers carry a given attribute |
| Sliced by | Form factor — portable, mobile, repeater | Protocol, ingress protection or another recorded parameter |
| Overlaps? | No. Every identifier sits in exactly one category. | Yes. One identifier appears in several collections. |
| On this site | Portables, Vehicles and mobiles, Repeaters and project systems | The four pages listed below |
Collections
By protocol
P25 two-way radios
P25 is a standard rather than a brand, and it is usually named in the specification before any supplier is approached. What a programme has to confirm is the configuration.
By protocol
Analog two-way radios
Analog is not the previous generation of anything. For voice within a group it does the job, and a large part of this catalogue still supports it.
By rating
Radios recorded with an IP68 rating
IP68 is a rating, and on this catalogue it is recorded per build rather than per series. The identifiers below carry it; what it covers and what it does not is worth reading before you specify it.
Where these lists come from
Each collection is a rule applied to the catalogue at build time, not a list maintained by hand. An identifier appears because the catalogue records the attribute for it, and disappears the moment the record changes — so a collection cannot drift away from the identifier pages inside it.
Coverage reflects the 177 identifiers this operation currently records. A model absent from the catalogue may still be sourced.Enquiry
