{
Wireless telegraphy }
or {
Wireless telegraph } (
Elec .),
any system of telegraphy employing no connecting wire or wires between the transmitting and receiving stations .
Note :
Although more or less successful researchers were made on the subject by Joseph Henry ,
Hertz ,
Oliver Lodge ,
and others ,
the first commercially successful system was that of Guglielmo Marconi ,
patented in March ,
1897 .
Marconi employed electric waves of high frequency set up by an induction coil in an oscillator ,
these waves being launched into space through a lofty antenna .
The receiving apparatus consisted of another antenna in circuit with a coherer and small battery for operating through a relay the ordinary telegraphic receiver .
This apparatus contains the essential features of all the systems now in use .
{
Wireless telephone },
an apparatus or contrivance for wireless telephony .
{
Wireless telephony },
telephony without wires ,
usually employing electric waves of high frequency emitted from an oscillator or generator ,
as in wireless telegraphy .
A telephone transmitter causes fluctuations in these waves ,
it being the fluctuations only which affect the receiver .

wireless telephony A term describing a computer {network } where
there is no physical connection (either copper cable or {fibre
optics }) between sender and receiver , but instead they are
connected by radio .
Applications for wireless networks include multi -party
teleconferencing }, distributed work sessions , {personal
digital assistants }, and electronic newspapers . They include
the transmission of voice , video , {images }, and data , each
traffic type with possibly differing {bandwidth } and
quality -of -service requirements . The wireless network
components of a complete source -destination path requires
consideration of mobility , {hand -off }, and varying
transmission and {bandwidth } conditions . The wired /wireless
network combination provides a severe bandwidth mismatch , as
well as vastly different error conditions . The processing
capability of fixed vs . mobile terminals may be expected to
differ significantly . This then leads to such issues to be
addressed in this environment as {admission control },
capacity assignment } and {hand -off } control in the wireless
domain , flow and error control over the complete end -to -end
path , dynamic bandwidth control to accommodate bandwidth
mismatch and /or varying processing capability .
