New horizons in wireless telephony
How to organize communication in cases when it is necessary to maintain constant contact with employees who do not have a stationary workplace? The Kirk DECT-z 1500 system is both personal mobile communication equipment implemented in the DECT standard and a unique digital telephone network that opens a new page in wireless telephony
Sooner or later, the head of any growing and developing enterprise faces questions regarding the organization of communication, for example: is it always possible to find an employee in the company's office? How much time does it take? How many questions from clients or potential customers remain unanswered because there is no way to quickly find an employee who can clarify the situation? But there are areas of activity and situations in which such a state of affairs is unacceptable. In addition, many enterprises need to maintain constant communication with employees who do not have a stationary workplace.
Solving such problems is one of the main purposes of personal mobile communication equipment implemented in the DECT standard. This standard is specially developed for such applications and, according to Order No. 128 of the Ministry of Communications of Russia, does not require a laborious procedure for allocating a frequency range for the system to operate.
Kirk DECT-z 1500 Mini-Cellular Communication System: Advantages and Possibilities of Application
The Kirk DECT-z 1500 system is a simple and effective solution for a company or organization whose employees are on the move. The system is a radio extension for wired corporate and public networks. The Kirk DECT-z 1500 can be connected to any PBX or public telephone exchange that has a standard subscriber connection kit.
Both tone and pulse dialing methods are used to transmit the dialed number. The system is easy to deploy, configure and operate. The system's radiotelephone can be registered in several offices equipped with Kirk DECT-z 1500, which makes it possible to use the system in companies with several departments or branches. One system can support up to 16 «cells», covering an area from 0.04 to 5.76 km. At the same time, up to 64 mobile subscribers can work simultaneously. It is possible to connect a concentrator controlled by external signals (for example, from an alarm system), which will automatically create text messages and send them to the mobile devices of the system subscribers.
The described properties of the system make it indispensable for such organizations with a high level of employee responsibility as banks, hospitals, security and emergency services, airports. In addition, Kirk DECT-z 1500 will be of interest to enterprises occupying large areas and not provided with wired communication systems everywhere: warehouses, large industrial facilities, supermarkets.
Finally, another important advantage of the system is that at present there are practically no procedures or equipment that allow listening to conversations transmitted in the DECT standard.
A separate area of application for the Kirk DECT-z 1500 is wireless fixed subscriber access applications. In cases where it is not possible to deploy traditional cable networks and the number of subscribers to be connected is small, the Kirk DECT-z 1500 allows you to organize radio access to regular telephones, fax machines, or modems. To do this, the subscriber's mobile handset is replaced with fixed radio access devices with the connection of one to four subscriber terminals.
Using directional antennas in a set with the base radio station, you can remove the radio access device at a distance of 3-5 km from the base station. A typical area of application for such a system configuration is the installation of telephones in small residential areas, such as cottage villages, or the organization of communications at enterprises scattered over large areas with a low density of fixed subscribers.
Wireless telephony increases mobility and productivity of communication and increases the chances of talking to the right person at the right time. Wireless phones have already become quite widespread, but the Kirk DECT-z 1500 system is not just another wireless phone, but a unique digital telephone network that opens a new page in wireless telephony. Using the Kirk DECT-z 1500 system means that visitors, colleagues and management employees can contact key employees of the company if necessary. After installation, all that remains is to say goodbye to yellow pieces of paper on which messages are usually written that are always lost.
Components of the Kirk DECT-z 1500 minicellular communication system
The Kirk DECT-z 1500 system structurally consists of several components that are used to manage the connection and maintain radio communication.
Central Control Functional Facility (CCFP). The main function of the CCFP is to manage the process of organizing and maintaining communications in the system. Base transceiver stations that provide radio communications with mobile subscribers and connecting lines for connecting the system to a wired communications network are connected to the CCFP. In addition, the CCFP contains text and digital information about the system subscribers, a bank of text messages, and memory for storing a phone book.
Fixed Radio Facility (RFP)— is the base radio station of the system (the main component of the «cell»). Its task is to organize a radio channel to a specific mobile subscriber. RFP is connected to the CCFP with one twisted pair of wires and in the standard version does not require its own power supply. RFP supports a radio channel in the DECT standard according to the GAP specification. In the basic version, RFP has a circular antenna pattern, providing uniform radio coverage. If necessary, RFP can be equipped with a directional antenna, increasing the radio coverage area in one of the directions.
A portable mobile telephone (PP) is a portable handset of a microcellular system that has a standard telephone keypad, function keys, and a display.
Using the function keys, you can select from a menu of functions that adapt the operation of the handset to each specific user, establish or terminate a connection, adjust the volume, and receive and send text messages.
The handset display helps the subscriber navigate the system, read text messages, control dialing, and identify the subscriber calling him.
You can connect a headset to the handset, consisting of a compact microphone and earphone, which will free the speaker's hands for work during the conversation. In addition, you can activate the automatic answer function, then instead of ringing, the handset itself will switch to connection mode as soon as it receives a call.
To maintain the handset battery in working condition, there are individual (for one handset) and collective (for four handsets) charging devices SN.
Additional devices.
To better meet the needs of each customer, the system includes the following components:
— fixed subscriber unit (FAU) — a stationary subscriber unit, with its help, stationary subscribers and various standard data transmission devices, such as a fax or modem, are connected via a radio channel;
— CRFP repeater is a wireless base station that complements RFP. It is used in places where it is not possible to connect RFP to CCFP via wires or when it is necessary to increase the radio coverage area of one «cell»;
— the RFP outdoor container allows the installation of base stations outdoors and provides support for the temperature and humidity conditions inside, necessary for the operation of the RFP, under any climatic conditions outside.
