One-way POCSAG and multi-way POCSAG+ paging and messaging
POCSAG is the time-proven and still the golden standard for high-performance digital paging. Paging systems based on POCSAG are flexible in configuration and usage, highly effective with the outdoor and indoor coverage, and are undemanding to the frequency range.
Based on POCSAG technology and with the usage of superior quality Oelmann products, it is easy to design and build modern paging systems of all levels, including:
Compact high-effective paging for hospitals, stores, and small businesses.
Medium-sized paging for cities, shopping malls, large hospitals, campuses and large enterprises.
Regional or national paging with full featured connection to the operational centers of rescue and security services.
So, why is it still paging today, in the era of instant IP-messengers in smartphones?
Because for professional networks and users, guaranteed delivery of messages and signalling is important, especially in critical lifesaver situations. This is still not possible and seems never will be in the case of public broadband networks.
The coverage of paging base stations is also incomparable with TETRA or cellular ones, of which several times more are needed for similar coverage.
Also, and very important: operational reliability. High quality pagers are narrow-functional inexpensive devices that cannot be used outside of paging purposes. They cannot get hang due to an update or OS crash like in a smartphone, or a virus or improper use of a smartphone, etc.
The pager alarm sound is designed to be louder and penetrate walls and winter clothing, which is important for evacuation signals or danger warnings.
If a silent alarm is required, the pager's vibrating alert or light alarm is also designed for excellent recognition in any environment or light.
The low initial investment in equipment costs, frequency licensing, and low cost of ownership of paging systems.
In addition to the standard signaling, Oelmann pagers:
are RGB colour-backlighted ones, programmable to follow messages or addresses with different colours.
use industrial LED technology to always recognize the message text in direct sunlight.
To ensure that the message is received by all pagers, including those that changes locations fast or located in an coverage edges, Oelmann intelligent PRS Series base stations and SIRIUS software send a critical message twice or more time (programmable, separate for each coverage area if needed). Oelmann pagers detect and reject duplicates to accurately follow only alarms without unnecessary noise.
Oelmann also has all kinds of paging gateways to third-party systems like TETRA, DMR, GSM/LTE, WiFi to extend the alarm action of the latter.
Standard signaling and paging of POCSAG is a one-way distribution of high effective digital radio telegrams, each of which consists of several messages and their recipient addresses. The pagers are preprogrammed and configured to receive these telegrams and always receive and decode them. If the telegram contains a message with the address of the pager, the pager displays this message with the appropriate sounds and other effects (vibration, glow or change in the display color). Pagers can be programmed to have one or many addresses, which allows you to have both an individual pager number, and groups and subgroups from in accordance with the task.
Oelmann has all the necessary components to build any type of POCSAG system, or to complement existing ones. Highest quality pagers of various types, various base stations and smart repeaters, software. As part of an add-on, update, or replacement for a modern one system, with full support and a service guarantee.
To expand and modernize the standard one-way paging capabilities of POCSAG, Oelmann produces pagers with feedback options, which allows you to design systems with acknowledgment of receipt, with auto- or a manual alarms from a pager, or, in the case of background polling, to have a complete picture of the activity and availability of pagers in real time.
Two-way professional mission-critical paging and messaging
The TETRA standard offers a two-way exchange of short text messages to an individual or a group of subscriber terminals, with automatic acknowledgement of receipt of the message. In network- or a cell-wide TMO (within the network base stations coverage) and also in DMO where the terminals communicate directly with each other (standalone mobiles and groups). If "silence-on-air" is required, there is a "TxI" mode (no radio transmission from the subscriber).
Oelmann was one of the first companies to create modular TETRA pager, now in use in many professional networks worldwide.
Today, in the year 2021, the Oelmann TETRA pager line is in full production, and contains the following models:
Standard and enhanced versions of the TME260 series pager with the man-down detector, indoor location beacon detection and alarm button for high-grade personnel security applications.
Oelmann WiFi pager is the professional multi-functional portable IP-device for high-speed bi-directional wireless communication in any WiFi networks. There are two types of WiFi pagers: the WME266 WiFi pager based on Oelmann Viper modular platform, and the newest pager from the LX7 series .
With Oelmann WiFi pagers, you'll get:
Compact fast deployable two-way IP-wireless signalling and messaging solution, in any WiFi network.
With server software or without as a standalone solution.
Basic WiFi pager functions:
Instant reception and display of an IP-text message or alarm, with auto-acknowledgment
Sending messages to any of the IP devices/apps
Signaling with sound/color/vibro or silent alarm
Receiving an alarm from other IP-pagers or from an optional relay contact panel
Auto sending IP-alarm according to the input contacts or man-down activity
WME266 Series WiFi pager features and options:
WiFi 2/5 GHz WPA2
Sound/vibro/backlight or silent alert, in any combination
Any language message text, scalable
RGB-color backlight, programmable
GPS receiver, inductive beacon decoder

Custom pre-recorded alarm sounds or voice notifications
SIRIUS system and SIRIUS software suite client-server solutions
SIRIUS is an Oelmann original modular platform for professional messaging applications . The entire SIRIUS system consists of control software, infrastructure components and base stations, gateways to third-party systems, and subscriber portable devices. It is used to build systems of any complexity, from local paging tasks to regional or national paging, two-way or multipath messaging systems, including the interaction of communication protocols of any type.
