Land cellular radio (LMR) applied sciences, which give public security radio entry, play an important position in our lives. They allow emergency providers to coordinate incidents, entry important information, and guarantee personnel security by way of dependable voice and information communications.
In america, the P25 (Mission 25) customary is used for public security communications. P25 helps both FDMA (Frequency Division A number of Entry), which makes use of 12.5 kHz channel spacing, or 2-slot TDMA (Time Division A number of Entry), often known as Part 2, which maintains the identical 12.5 kHz channel bandwidth whereas doubling spectral effectivity for voice visitors. Interoperability throughout businesses and producers is a core requirement of P25, making certain that totally different tools can function collectively on shared networks.
In Europe and plenty of international locations in Asia, the TETRA (Terrestrial Trunked Radio) customary is often used. TETRA employs 4-slot TDMA inside a 25 kHz channel, offering each voice and information providers with excessive spectral effectivity, notably for brief information packets and management signaling. Some areas, similar to China, have developed their very own digital trunking requirements, similar to PDT (Police Digital Trunking), which serve related roles however are usually not based mostly on TETRA.
Globally, there may be additionally a transition in the direction of safe mobile expertise to complement mission-critical information and voice communications.
Public security communications infrastructure is, nevertheless, extremely advanced. There has historically been challenges in terms of deploying, sustaining and troubleshooting these applied sciences. Area technicians want complete but user-friendly and intuitive instruments to finish their work precisely and shortly.
VIAVI CX150
To deal with these challenges, VIAVI has launched the hand-held CX150 CommLite instrument for analog mission-critical radio networks. Constructing on our CX200 platform, the CX150 has been particularly developed to ship the subset of instruments particularly required for analog radios. Briefly, it incorporates the preferred options from our industry-leading take a look at units into an economical field-portable bundle with out sacrificing specs or efficiency.
The CX150 allows customers to carry out important checks, together with duplex, transmit, and obtain measurements, spectrum evaluation, and elective cable and antenna evaluation options for measuring Distance-to-Fault (DTF) and VSWR. It additionally integrates with VIAVI’s VIP Instrument for automated take a look at sequences and helps StrataSync for reporting, information storage, and asset administration.
The CX150 is remotely accessible and controllable by way of the Good Entry Wherever software program, with distant coaching and help out there.
VIAVI CX200
The brand new CX150 joins the CX200, which was launched in March 2025. Each incorporate VIAVI’s industry-leading suite of take a look at functions, which ship quick, repeatable, and correct take a look at and alignment outcomes which can be trusted by radio producers and repair facilities worldwide.
Each the CX150 and CX200 additionally implement particular person and total cross or fail flags to additional simplify go/no-go testing, serving to to get rid of errors, with the CX200 enabling area engineers to additionally take a look at digital community options.
See it at APCO 2025
The CX150 shall be formally launched in Baltimore MD at APCO 2025, the premier occasion for public security communications. In the event you’d like to seek out out extra concerning the CX150 or the CX200, please cease by our sales space #3007.
