Difference between P25 and DMR two-way radio systems
P25 is the digital standard for public safety grade two-way radios. Offering very high levels of encryption, trunking formats, GPS and over the air programming combined in an industry wide accepted format. This format guarantees that, if the two-way radio is P25 standard, it will work with other P25 standard two-way radios even from different manufacturers. This allows Police, Fire and other public safety departments to be able to communicate with each other during an emergency, yet maintain their private networks during day to day operations.
DMR (Digital Mobile Radio) is the private industry version of a digital standard. Radios from multiple vendors designed with the DMR standard are guaranteed to work with each other. A Tait DMR two-way radio will work with a Hytera as well as Vertex Standard and MOTOTRBO. This offers flexibility as well as healthy competition when customers are trying to decide which product to purchase. Offering features such as one to one, one to all, group calls, GPS and text messaging, the DMR standard creates a new level of utility for the two-way radio.
DMR repeaters are designed to allow two users to share the same repeater at the same time without interference. This provides companies a two for one feature. Presently in analog operation one repeater is required for each group.
DMR has also opened the door for software designers to develop software products that will work with the radios. Just like smart phone applications, DMR applications are now offering value added features such as work flow reports and trouble tickets. With all these features available to the user, DMR still provides for analog communication. This guarantees a smooth migration with older legacy radios that customers may not be able to replace now.
