pager questions

[poltergeisty]

Dose any one know what a reflex format is? When you hear it sounds exactly that a continuous data sounding like flex but repeating. Is this some kind of pager control channel? Or do they not have a control channel?

Is mobitex a pager format or a mdt. format or both?

Has there or is there any encrypted pager formats out there?

RefleX is just as you described it.. It upgrades basic FleX technology so that it repeats the data streams for a better continuity and to ensure the information is not corrupted. It also allows more pagers/pdd's "beepers" to be on the system. BTW.. you do kow that unless monitoring pager TX is part of your job, it is illegal to do so intentionally?

As for Mobitex.. I have no information, sorry.

On a side note: Isn't it amazing how much the old "beeper" technology has grown and changed over the years? From the "purse" beepers of the late 80's to the newest micro pagers.... More info allowed in the streams, better quality of data.. less bogus, or dropped pages....

And with the newer Two Way pagers,.. its so much easier to SMS text than it used to be... Some of these are not even pagers anymore but a hybrid quasi PDA,.. thus the term PDD- Personal Data Device.
You can almost see the end of paging as we know it... And (hide anti trekkers) with the rapid growth, I do forsee an combined compact multiple use device almost like a combadge lol... Cellular/PDA/Pager/SMR/Game System.. with satcom linkage. All in a device the size of say... a Motorola Razor flip phone....

This isn't 100 percent correct. reFlex is a protocol which builds on the existing Flex protocol to provide two-way paging. It retains similar error protection, addressing schemes and message synchronization, but adds additional commands to accomodate two-way messaging. There are other differences as well, but the differences have nothing to do with repeating data streams.

Yes, encrypted messages are also possible with flex. Numeric, Alpha, Raw binary or hexidecimal, Secure, and Instruction messages are possible.

I have wondered what is the raw binary and hex for? And what is the difference between secure and encrypted? And what are instruction messages?

 

[gr8amp]

The binary and/or hex data is usually used for data receivers that aren't pagers. Sometimes its an easy way to send data over a wide area without having to deal with private frequency allocation, equipment costs, and maintenance.

Secure and encrypted are the same thing in the sense that a secure message is encrypted.

Instruction messages can be used for over the air programming, however I have never seen it used.

Ok, Thanks Jim.
Now about these data receivers what are some examples. Some might be utilitys and the like I think?

 

[gr8amp]

They are used for many things. Traffic signal control, and highway signboard programming come to mind. But they aren't limited to these uses by any means.

Wow even the sign boards. Thanks. Man I sure learn alot from here. :wink:
