Radio Replacement with the Sonim XP series and Push to Talk over Cellular"
loading="eager" />
Historically, radio systems, such as land mobile radio (LMR), have been a cornerstone of mobile critical communications, particularly in industries like public safety and transportation as well as construction, hospitality, retail, and more. The simplicity and reliability of instant Push-to-Talk (PTT) communications with radios (both LMRs and walkie-talkies) are considered essential for critical communications, especially when involved in a dangerous or high-pressure situation where dependable ease of use is a top priority.
However, with the tremendous advances in cellular communications and low-cost devices with multi-faceted capabilities, moving beyond a simple verbal exchange can be just as important during emergency and/or business-critical situations.
Interoperability, price, application support, and accessory support are some of the key reasons why using the Sonim XP series of rugged phones as a PTT over Cellular (PTToC) solution is a great replacement or addition to your existing radio solution.
Interoperability
The interoperability provided by a rugged handset with PTToC capabilities, like the 5G, is owing to a more effective response.
The XP series with PTToC can work alongside existing LMR systems, allowing organizations to modernize communications without requiring an all-or-nothing transition away from radio. Through supported PTToC solutions with LMR interoperability, users on Sonim XP series phones can communicate with teams operating on traditional two-way radios while gaining the benefits of broadband connectivity and expanded capabilities such as messaging, location services, image sharing, and other data-enabled workflows. This gives organizations a practical way to extend the value of their existing LMR infrastructure while introducing more advanced communications where and when they need them.
Utilizing Sonim’s powerful XP5plus 5G handset as a PTToC solution enables users to communicate and connect with other Wi-Fi and Bluetooth-enabled devices, such as body cameras and wireless headsets, and share captured information over PTToC in real time. By making this information available across both broadband and LMR-connected users, organizations can improve coordination, share a common operating picture, and make more informed decisions during routine operations and emergency response scenarios.
When the cost of LMR adds up
Traditional LMR systems can require significant investment in radios, repeaters, towers, and ongoing maintenance. As organizations grow, those costs can add up quickly, whether they are investing in infrastructure or paying recurring costs to rent LMR devices.
Avoiding a $130,000+ LMR upgrade
One school bus fleet in the Midwest was facing a proposal of more than $130,000 to expand its existing LMR environment with just two repeaters and radios.
With tight budgets, the district needed a more future-ready alternative at a fraction of the cost. Rather than make another major investment in aging LMR infrastructure, the organization deployed Sonim XP5plus 5G devices with Push-to-Talk over Cellular and interoperability software.
The solution saved the district tens of thousands of dollars in upfront infrastructure costs while adding encrypted communications, GPS location services, multi-channel communications, cloud-based device management, and coverage beyond traditional radio boundaries.
Cutting nearly $2,600 per device from LMR rental costs
For another organization, the cost challenge wasn’t upgrading LMR infrastructure. It was the ongoing expense of renting LMR devices.
A global leader in energy and environmental technologies and services, referred to here as “Company X,” compared its existing LMR rental model against Sonim XP5plus 5G and XP Pro devices.
The company’s own cost analysis showed a significant financial impact: nearly $2,600 in savings per deployed communication device. At fleet scale, the comparison demonstrated just how quickly the recurring cost of rented LMR devices can add up.
Ultra Rugged Capabilities
Like all Sonim devices, the Sonim XP5plus 5G is tested with industry-leading Rugged Performance Standards in mind and is military rated for its durability. All of Sonim’s ultra-rugged devices, including the XP5plus 5G, can be aggressively cleaned and disinfected. This includes being fully submerged or cleaned with a variety of different cleaning products, from simple soap and water to heavy-duty cleansers and disinfectants, such as bleach and isopropyl alcohol.
Sonim devices are also backed by a 3-year robust warranty. Other device manufacturers recommend “gently” cleaning or caution you to avoid using aerosol sprays, antibacterial products, bleaches, and other cleaners directly on the device or risk voiding their warranty. This is not necessary with a Sonim device. With Sonim's ultra-rugged devices, you can clean away without worry that you'll ruin your device or lose your warranty.
