Talk:Mobitex

How do you access and use Mobitex?

A dedicated radio modem is required to access Mobitex networks. They may be connected to a hardware device or built into a device. It is designed to be used as a host to mobile system. Gorebridge (talk) 22:22, 20 October 2010 (UTC)[reply]

Who is the provider?

There are several Mobitex operators around the world, but some modems may only be compatible with their "home" network. The technology is owned by Ericsson. Gorebridge (talk) 22:22, 20 October 2010 (UTC)[reply]

..and how does/did it work? Technical details please!

A cellular system originally designed as an emergency radio for telephone engineers working in remote areas in Sweden, it developed into a packet data radio system. Data messages are "broken" into packets and sent to a network base station, from where they are normally delivered to a host system - typically a fixed computer database system. The system is two way i.e. host to mobile, mobile to host. Peer to peer data messaging is also possible. The network uses a negative acknowledgement system, informing a sender only if a data message is not delivered. Positive acknowledgements have to be generated at software level and sent across the network as a data packet. In a "machine-to-machine" environment positive acknowledgements are unnecessary. The network does incorporate a mailbox, where packets can be stored for a specified amount of time, if the receiving modem is switched off or out of coverage. Packets are automatically forwarded when the modem next comes into contact with the network (i.e. is switched on or comes back into coverage). Data stored in the network generates a negative acknowledgement, confirming the packet has been stored.

Unlike other types of radio systems, Mobitex networks also provide real "push" technology, in other words it doesn't require any kind of handshaking to accept data packets from a device. It is a send and forget system.

At the present time it is the world's most reliable, secure, and robust wireless data system Gorebridge (talk) 22:22, 20 October 2010 (UTC)[reply]

The authos seems to be very wrong about the history of Mobitex... I'll look into it. // Liftarn

BT are the owners of the UK network, but they did not purchase it until around 2004/2005. Gorebridge (talk) 22:22, 20 October 2010 (UTC)[reply]
