PageNet. PageNet, also known as Paging Network, Inc., was founded in 1981 by entrepreneur George Perrin and ceased in 1999. The company grew to become the largest wireless messaging company in the world, with more than 10 million pagers in service, and $1 billion in revenues, before the paging industry's rapid decline in the late 1990s.
A pager, also known as a beeper or bleeper, [1] is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter.
A transmitted message may be broken into a sequence of packets before transmission, which are then re-assembled into the original message upon reception; Packets for multiple destinations can be transmitted on the same radio link in an asynchronous fashion; A packet may be addressed to all possible recipients rather than a specific one
Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves, analogous to electrical telegraphy using cables. [ 1 ][ 2 ] Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires. [ 3 ][ 4 ] In radiotelegraphy, information is ...
A personal communications service (PCS) is set of communications capabilities that provide a combination of terminal mobility, personal mobility, and service profile management. [1] This class of services comprises several types of wireless voice or wireless data communications systems, typically incorporating digital technology, providing ...
Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. [1] The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same ...
It is a service that consists of live operators who answer incoming calls and input the callers' messages on a computer, then transmit the message using the Telocator Alphanumeric Protocol to the paging provider's radio towers. Alphanumeric pagers receive the messages in the form of words and numbers. Messages are sequentially numbered and ...
Wireless ad hoc network. A wireless ad hoc network[1] (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes.
