![]() ![]() ![]() Push-to-talk over Wi-Fi is not limited to a single location. Dispatch applications can also utilize the GPS capabilities built into PoC devices to track employee locations throughout a large outdoor facility like a campus or entertainment complex (zoo, theme park, etc.). The last step is to configure PoC devices with call groups and device functions and distribute them to security staff and employees.įigure 3: Push-to-Talk over Wi-Fi NetworkĪ web-based dispatch application is used to initiate group voice and video calls from a single location. Then a Push-to-talk over Wi-Fi a server is installed to provide system connectivity between the Wi-Fi network, the PoC devices, and the dispatch application. The first step in a PTT over Wi-Fi deployment is to conduct a site-wide bandwidth audit to ensure there is enough coverage for the whole facility. Push-to-talk over Wi-Fi uses the existing Wi-Fi network and access points throughout a facility. Wi-Fi is nearly ubiquitous in all buildings and facilities, providing a wide-open opportunity for companies looking to leverage their existing investment in Wi-Fi infrastructure. This enables instant group voice and video calling in a large building, facility, entertainment complex, or campus with Wi-Fi network connectivity. PoC devices also support Wi-Fi connectivity. Dispatchers are typically web-based applications allowing for easy deployments and minimal start-up costs. PoC dispatch applications that support Geo Fencing provide alarm triggers when guards enter hazardous areas, or when mobile patrols stray from defined territories. This is an essential tool for managing, scheduling, and tracking security guards and mobile patrols. PoC devices with integrated GPS enable location tracking with a dispatch application. PoC devices with video capabilities enable instant video conferencing with dispatcher applications. One press of a button on a rugged handheld device and you are talking to your group or an individual. PoC technology enables subscribers to make one-to-one (individual) calls or one-to-many (group) calls to different groups of people at the same time over a mobile operator’s network. PoC radios and bodycams can work out-of-the-box with SIM cards pre-installed, and system configuration is done through an easy-to-use web-based dispatch application. LTE and Wi-Fi networks also provide the bandwidth for reliable bodycam video streaming.Īnother benefit of using cellular and Wi-Fi networks is that PoC systems can be deployed very quickly. This reduces capital equipment costs, day-to-day operating costs, and eliminates the need for expensive frequency licenses required by private LMR systems. Since PoC uses existing 3G/4G/LTE and Wi-Fi networks, there is no need to purchase, operate and maintain any infrastructure. Think of PoC as Radio as a Service, where the only up-front investment is the PoC devices and SIM cards. PoC is based on Operational Expenditures (OPEX) with a low-cost, subscription-based service. Traditional wide-area private radio networks require significant up-front Capital Expenditures (CAPEX), that include base stations, repeaters, routers, and antennas. PoC also provides a cost-effective solution for organizations, such as retail outlets or hotels, where traditional Land Mobile Radio (LMR) solutions might be more than is required or too high of an investment. PoC is particularly useful for businesses with vehicle fleets and employees such as security guards that work inside and outside the vehicles. These include security, construction, healthcare, hospitality, property management, manufacturing, and others. At its peak in 2005, Nextel had over twenty million subscribers in the United States and served 198 of the top 200 markets.īusiness which use PoC services are looking for wide-area communications with a low startup cost. There has also been a proven demand for PoC services. In June of this year, Forbes Business Insights estimated that the global PoC market value was $12B in 2019 and projected it to reach $25.5B by 2027 with a Compound Annual Growth Rate (CAGR) of 10%, and North America is expected to lead the market share during that period. The PoC market is growing at a healthy rate, and it is driven not just by LTE technology, but also by the increase in mobile workforces, and the global adoption of the Internet of Things (IoT). Radio users can belong to multiple groups as shown in the overlapping areas. PoC provides the same group calling capabilities as traditional two-way radio systems to enable instant group calls to multiple users with the press of a PTT button on a radio or from a dispatching application.Ĭall groups are set up based on all call and emergency calls, types of employees (supervisors, administrators, etc.), single-site guard staff, and mobile patrols, etc. ![]()
