Professional mission–critical radio paging, standard and extended
POCSAG is the time–proven golden standard for high–performance digital wireless paging. POCSAG paging systems are flexible in configuration and usage, highly effective with the outdoor and indoor coverage, and are undemanding to the frequency range.
Extreme flexibility in frequency planning, simplicity of base stations and the ability to use any number of repeaters allow building highly efficient paging networks without high initial and operational costs.
Pocket size, high performance, position–independent internal antenna and long battery life make the POCSAG pagers ideal for any application, including mission-critical solutions.
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 and events.
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.
Fire alarm, code blue and nurse call systems are standard use cases.

Why POCSAG paging and what it is for
POCSAG digital paging today, in the era of instant IP–messengers in smartphones
Standard POCSAG paging
Standard POCSAG paging is a one–way distribution (broadcasting) of highly effective digital radiotelegrams, each of which consists of several messages and their recipient addresses.
Coupled with effective digital modulation and error tolerance for decoding received messages, this is an extremely effective technique for instant wireless alerting any number of users.
Paging base stations encode and broadcast on-air telegrams, which include one or several messages to different recipients. Messages can be text or empty (then only signalling will be accepted), and also have four subaddress prefixes.
The pagers are preprogrammed and configured to receive these telegrams, and they 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 colour).
Pagers can be programmed to have one or many addresses, which allows you to have both an individual pager number, and groups and subgroups in accordance with the task.
Key features of POCSAG paging:
Guaranteed delivery of messages and emergency signalling for professional users it is the key point, especially in critical lifesaver situations. In the case of public broadband cellular networks, guaranteed delivery is not possible.
The coverage: paging base station coverage is much wider and incomparable with any cellular ones, of which several times more is needed for similar coverage.
Subscriber terminals operational reliability: high-quality pagers are narrow-functional 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, games or improper use of.
The pager alarm sound is designed to be louder and to penetrate winter clothing and walls, which is important for evacuation signals or danger warnings.
If a silent alarm is required, the pager's vibrating alert or backlight alarm is also designed for excellent recognition in any environment or light.
POCSAG paging systems have low initial investment in infrastructure equipment costs and frequency licensing, and low cost of ownership.
Oelmann POCSAG additions and enhancements
To ensure that messages are received by all pagers, including those that quickly change location or are at the edges of the coverage area, Oelmann smart base stations and SIRIUS software send a critical message twice or more times (this is programmable, and can be different for each coverage area). Oelmann pagers detect and reject alarm duplicates, reacting to only real alarms with no repeating it.
Thanks to intelligent real-time decoding procedures, Oelmann's pagers "understand" where the error is in the message (if any) and highlight the place of the questionable symbol.
To expand and modernize the standard one–way paging capabilities of POCSAG, Oelmann produces pagers with feedback options, which allow designing systems with acknowledgement of receipt, with auto- or 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.
All Oelmann pagers are equipped with industrial LED backlight technology, allowing the message text to be recognised at all times, also in direct sunlight. The backlight is RGB-coloured, programmable for focusing messages with different backlight colours.
Oelmann has all the necessary components to build any type of paging system or to complement existing ones, as part of an add-on, update, or replacement for a modern one system, with full support and a service guarantee.
