In this Technical Report a number of issues are raised regarding the measurement and reporting of pager sensitivity. As sensitivity is such a critical aspect of network design, especially for emergency services networks where coverage may be a life and death issue, it is important that practitioners have a common understanding of the various terms used, and the ways in which technical data gets used (or abused).

The report highlights the importance of clarity in stating the acceptance conditions, and especially notes that testing based on the international standards may be useful for pager-to-pager comparison, but may not yield useful results for network design unless fully understood.

The report also provides guidance on the basic set of information that should be noted in specifications, and highlights the fact that many manufacturers do not qualify their stated sensitivity with this data – making the information difficult to interpret accurately.

This White Paper is provided by EMMA, the European Mobile Messaging Association, and considers the use of paging networks around the world in callout systems for emergency services first responders. It provides a concise summary of the world experience, and highlights the advantages of using paging networks for this purpose.

This White Paper discusses some of the issues that must be considered when designing a simulcast paging system, particularly a system that is based on Infostream's CYPHER paging encoder system.  The Paper covers the difficulties of designing coverage overlap with multiple transmitters, together with issues surrounding propogation delays, and shows how the use of modern GPS systems and Infostream's Cypher encoder can be structured to appropriately deal with these issues.

This White Paper examines the potential pitfalls and necessary precautions that must be observed when undertaking testing and electrical characterization of FLEX pagers. It considers the impact of the synchronous nature of the FLEX protocol and the potential skew of test results caused by emergency resynchronization codeword design, and suggests approaches to overcome these issues.

This White Paper examines the use of the FLEX protocol in emergency services networks. Although at first glance the FLEX protocol offers some advantages, there are significant obstacles that must be overcome to ensure a reliable network.  The White Paper examines these issues (both in terms of network and pager design), and provides guidance and alternative approaches to overcoming the challenges of providing reliable FLEX networks for emergency services wide area systems.
