What is (RoIP) Two-Way Radio over IP?

Radio over Internet Protocol (RoIP) provides an intelligent and flexible way to extend the reach and improve the efficiency of two-way radio by leveraging existing investments in IP networks. Organizations can seamlessly distribute workloads between operations centers to cover peak periods and improve responsiveness during disaster situations or system failures. RoIP allows two-way radios to communicate with desk and mobile phones providing communication flexibility and reducing overall costs.

Today radio communications are restricted to the range of an organization’s base stations. RoIP is a suite of technologies that allows two-way radio traffic to be transmitted over an internet protocol network. RoIP extends the reach of radio systems by using an organization’s existing wide-area network (WAN) infrastructure to route radio signals between base stations. By installing radio-enabled gateway routers at base stations and dispatch consoles voice signals can be transported over an IP network.

Operations center administrators can use a graphical interface to control traffic and allocate workloads. When combined with Voice over IP technology dispatchers can just as easily route radio traffic to a phone extension external land-line or mobile phone. This allows faster communication between employees and broadens the reach of an organization’s communications systems.

SiteCAST Client Radio Software license works with Our Computer Creations TPC Products.

  Our Smart-Phone software turns your Internet-enabled Cell Phone devices and into software defined radios or “soft radios”.

Users of Internet enabled handheld devices often work with employees who communicate on dedicated two-way radio systems for mission or business critical tasks. These two types of devices could not historically talk to one another due to fractured and incompatible wireless architectures. With iWalkie users are able to seamlessly communicate with all makes and models of two-way radios when operating together with SiteCAST and SafetyNET enabled systems.
With iWalkie worldwide PTT is both cross platform and network neutral. IWalkie operates on any cellular WAN WiFi or wireless data network – public or private. Users can be on any combination of wireless data networks anywhere in the world eliminating the need for inflexible and expensive carrier-centric ascending PTT.
iWalkie uses the 2G/3G/4G data mode of your device rather than the cellular voice telephone mode. iWalkie users avoid costly minute-based airtime charges associated with cellular voice calling and can communicate mobile-to-mobile with lighting speed in group or private talk formats.
Our patent-pending iWalkie software also supports multi-tasking. iWalkie stays connected while performing other tasks including email maps tracking inventory running a credit card looking up criminal records or submitting a work order just to name a few.
iWalkie loads easily onto devices via cradle sync push download or direct download. It imposes minimal use of network resources and storage footprint due to its thin-client architecture.

 No matter what your workers need to get the job done Motorola’s MC75 Worldwide Enterprise Digital Assistant delivers by combining an unparalleled number of business capabilities into an easy-to-carry rugged device. 3.5G HSDPA and 3G CDMA-EVDO (Rev A) support provides high performance voice and data services around the globe.
