internal (within a service), and external (e.g., as a part of the national emergency system). The PIK communications integration platform relies on the network of the communications gateways with a native in-service communications system, transferring a voice and data through the VOPP to the gateway of other service or a dispatcher. To simplify, think about the solutions as a dedi- cated phone line operated by mobile phone base transceiver station (or BTS in short), not by radio waves. The access gateways have interfaces com- patible with communications system of a particu- lar service, and communicate with the remaining system components via network data packets via cellular (CDMA, UMTS/HSPA) and WiFi and cable networks. The main difference between the PIK and other communications systems is virtually unlimited range coverage area and a lack of the necessity to exchange the currently deployed digital commu- nication systems like DMRs. There is no necessi- ty to plan, develop or maintain an infrastructure, and developing a communications system leads up only to a purchase of the necessary devices (mobile and/or fixed ones) and "plugging-in" all the current devices to the system. It also means a diversification of the purchases and an opportuni- ty to buy digital communication systems from any manufacturer. The PIK system features also server-side which ensures a remote configuration, as well as conti- nuous operation because of MM-IP-Mobility tech- nology used to switch between multiple mobile networks. The gateways analize in real-time ava- ilability and quality of the radio interfaces and se- lect the best connection to transfer the data pac- kages. From the end-user point of view, switching between various mobile networks and keeping a communication in the case of losing one of the radio connections MM-IP-Mobility is virtually un- noticeable. The PIK is a dispatch communication system which enables configuration tailored to situation. Each gateway may provide data encryption, GPS loca- tion service or even secured WiFi network which allows for a data transmission or an access to the additional information. A reliability of the commu- nication is simultaneously ensured by using vario- us, in terms of the physical properties, 3G/4G and CDMA mobile networks and due to the extended antenna systems independent communication ADVANCED TECHNOLOGIES
