JPS invented RoIP (Radio over IP) in the late 1990s to provide a secure, cost-effective means of expanding Land Mobile Radio (LMR) coverage. It has since evolved to support additional functions critical to communications users, such as remote dispatching and interoperability.
RoIP is not VoIP – it is more than simply transporting Radio and other Push-to-Talk (PTT) communications across an IP network. JPS RoIP uses proprietary features specifically designed for interfacing to LMR systems, providing a seamless experience for system users.
RoIP utilizes existing network infrastructure (including the internet) to allow users to supplement their communications systems at a minimal expense. As a result, JPS customers routinely achieve a Return on Investment (ROI) within months of deploying RoIP devices.
These products also offer a substantial amount of flexibility, supporting any requirement from 1:1 standalone applications to statewide solutions. Devices are deployed in a fraction of the time compared to LMR Equipment, both temporarily and permanently.
One of the primary purposes of RoIP is to provide a cost-effective means of eliminating gaps in LMR coverage. This expands the coverage footprint across an IP network where radio coverage does not exist, replacing a traditional repeater.
In addition, it can provide communications interoperability by creating a connection between disparate radio systems regardless of manufacturer, frequency band, and signal type. For example, RoIP can be used when migrating an analog radio system to a digital radio system.
IP networks are not constrained by the same conditions as other communications networks, such as weather, foliage, or buildings and structures. As a result, the system remains reliable while providing access anywhere in the world, including harsh locations with no terrestrial coverage. The vocoders used in JPS products are lightweight and capable of traversing any network, including satellite.
JPS devices also provide the ability to integrate other communications devices. Dispatch consoles, VoIP phones, and PCs can all access LMR channels. One of the primary applications is to interface radios to Push-to-Talk over Cellular (POC) applications such as ESChat and Zello.
The NXU-2B is a single-channel standalone RoIP device that interfaces full duplex audio, one RS-232 port and four status bits onto an IP network. It is the most recent device in a product line (NXU-2, NXU-2A) that has seen tens of thousands of units deployed worldwide.
In addition to being built with modern components, the NXU-2B features a number of remote management functions. These include audio adjustment, reboot, and real-time status indication.
RoIP+™ (or RoIP Plus™) is an enhanced version of the RoIP protocol that offers AES-256 bit encryption along with the ability to carry metadata. This enhancement allows the capability of full end-to-end encryption of any communications channel.
RoIP+™ is currently available in the Z-Series line of products, which includes the ACU-Z1, Z2 Controller, and RSP-Z2. These devices may be purchased with RoIP+™ enabled, or it may be added later as a separate license.
