R&S®PostMan II Information and Communication System
Client-server architecture for advanced Internet/intranet communications via radio
Any e-mail client such as Microsoft Outlook or Lotus Notes can be used for e-mail transmission. To reduce transmission time, both the text body and the attached files undergo data compression. If the radio link is interrupted, R&S®PostMan II automatically attempts to contact the addressee even through alternative routes or media, depending on the chosen settings.
Fax
Faxes to be sent can either be generated electronically on a PC or placed in the fax machine as hardcopy. The destination address entered on a workstation terminal or the number dialed on a fax machine may be another computer or fax machine. If access to public telephone networks is available, worldwide fax service is possible.
Voice mail
Voice mail is used to send a voice message directly from a telephone. After the R&S®PostMan II telephone number and the recipient’s number have been dialed, a voice message can be left on the R&S®PostMan II server. R&S®PostMan II then automatically delivers the voice message as an e-mail attachment to the other party.
Radio telephony
Radio telephony is provided by using the automatic phone patch (APP) option for the HF Transceiver Family R&S®XK2000. This makes shortwave telephone calls possible.
GPS tracking
Another R&S®PostMan II feature is the capability to track mobile stations by using the global positioning system (GPS). If a station is equipped with a GPS receiver, position data can be transmitted in addition to the actual data after analysis of the National Marine Electronics Association (NMEA) protocol. The current position of and the route covered by each mobile station can thus be tracked from a command center. The standard package includes an interface with which scanned maps can be calibrated.
Chat
The chat service is used for realtime interactive e-mail communications between multiple parties. R&S®PostMan II uses the transparent TCP/IP mode to exchange the data, which makes it possible to expand this service to existing networks.
Encrypted transmission
All exchanged information can of course be protected against unauthorized access with the aid of customized encryption procedures. Several of encryption options are available, ranging from software-only or combined hardware/software solutions up to the integration of customized encryption units into the information flow.
