Everything for instant wireless alerting: professional digital paging, signalling and messaging. Single– or multi–path, with or without feedback. Professional mobile radio, voice and data communications.
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.
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:
Fire alarm, code blue and nurse call systems are standard use cases.
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.
Workflow:
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.
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.
Oelmann provides gateways to third–party systems TETRA, DMR, LTE, WiFi to extend the POCSAG with the multipath messaging and alarm actions.
Oelmann LX7 WiFi pager is the professional multi–functional portable IP–device for instant bi–directional wireless signalling in any WiFi networks.
For special or custom solutions, there are the LX7 Module or a Modem.
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) where the terminals communicate with each other, or within a mobile group.
Oelmann was one of the first companies to develop the modular TETRA pager, which today is effectively used in many TETRA networks around the world.
Today the Oelmann TETRA pager line is in full production, and it is based on standard, or personnel security enhanced versions of the TME260 Series pager with the optionals like man–down detector, GPS and/or indoor location beacon detection, alarm button and the tear–off alarm contact for high–grade personnel security applications. ATEX available.
Note: Oelmann has all kinds of TETRA base stations and switches to build a whole TETRA paging system, or to supplement the existing ones at the customer's site.
SIRIUS is an Oelmann original modular platform for professional messaging applications. The entire SIRIUS system consists of paging 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.
