The cell phone technology may be advancing at a mind-blogging rate, however, before cell phones were introduced and popularized in modern culture, the walkie-talkie was the most efficient method of sharing information over short ranges. Although walkie-talkies now seem old fashioned either as a communication device or as a simple fun tool, the invention of the walkie-talkie still remains of one of the breakthrough inventions in the telecommunications industry.
What is a walkie-talkie
The walkie talkie is simply a portable hand-held wireless radio device fitted with a microphone, a loudspeaker, an antenna and a “push to talk” button to enable short to middle range wireless communications. Here we will review Real Mobile's innovative and next generation walkie talkie - the Push to Talk (PTT) over cellular field handset.
Introduction to Real Mobile
Real Mobile is a telecommunications company offering full service PBX phones solutions on a hosted VoIP platform. The company also serves as a Mobile Virtual Network Operator (MVNO) offering nationwide LTE 4G wireless communications services. Real Mobile was founded in 2011 and operates out of Florida, USA. Among Real Mobile's wide range of products and services is the Push to Talk over Cellular field radios, which is comprehensively reviewed below.
A review of Push to Talk (PTT) over cellular radio
The Push to Talk Over Cellular walkie-talkie is a next generation device featuring an impressive set of components like field communicators and a multi-media dispatch and command system to allow for an easy and secured instant communication channel between groups without a range limit with just the push of a button. While the invention of the cell phone was undoubtedly the game changer, the cell phone is essentially just a telephone and gaming device that requires traditional dialing / calling protocols, this walkie talkie on the other hand provides instant contact, GPS location services and other multi-media services using nationwide cellular towers and/or WIFI to function to connect with an array of global servers … at the push of a button.
In point of fact, the major distinction between the PTT over cellular radio and the traditional walkie talkie is that while the range of functionality of the traditional walkie talkie is limited to the available radio towers or the line of site between radios, the REAL Mobile PTT device offers an unlimited range and worldwide coverage. Essentially, the PTT over cellular radio is powered by the built-in cellular internet which transmits service to Real Mobile's network of 28 servers spread out across the globe, 8 of which are located within the United States. The rugged field handset presently available is the RM-308 with various new models like RM-8S launching in the fall of 2018.
These model comes with GPS tracking, 3G network (ensures stability and wider coverage), IP54 dust/waterproof standards with a battery capacity of 3000mAh (extra large 5000mAh available). The RM-308 functions best between temperatures -30°C to 75°C.
