The Hawaiian gazette. [volume] (Honolulu [Oahu, Hawaii]) 1865-1918, 1912-07-19

Expert engineers will arrive in Ho-
nolulu within two months to begin the
work of erecting two immense high
power wireless stations here as a part
of world wireless system for which
active arrangements are now being car
Eied on by the Marconi Wireless Tele
graph Company. Frederick NJ Sam
mis-, chief engineer of the Marconi
Wireless Telegraph Company of Amer
lea, who has charge of all the work
in the United States and its posses
sions, has been here for several days
making arrangements for two sites. Ho-
nOlulu is to be the crossroads for this
world system with wireless connections
with San Francisco, Colon, Guam and
probably New Zealand.
Mr.. Sammis stated yesterday that the
new wireless system between Honolulu
and San Francisco would be in opera
tion within eighteen months and the
entire system by which Honolulans may
transmit wireless messages to all parts
of the world will be completed within
two years. The Marconi company is
now under contract with the Western
Union lelegraph company TO put the
new system from here TO the Coast IN
operation IN elghteen months and IN
order TO DO TINS the WORK Will be rush
cd as 1ast as posSlpie.
Lower Rates Promised
When the new system is in oneration
Mr. Sammis says messages may be sent
around the world with perfect rellabil-
ny twenty-1our hours IN the day and
500 days IN the year. Only nine high
power receiving stations scattered
throughout the world VIII be used ana
the Iact that the system wlll be oper-
ated with SO rev is really remarkable,
he says rms rs due to the nigh power
stations Best OF all he reports that
the charges Tor messages Will be very
reasonable, ns low as one'half to two
tnifdS the present caDie rate.

Will be transmitting and receiving

the receiving or transmission house
they will extend one mile in each di-

will be two miles.
'fBy this method the impulses are
transmitted in one direction only to
the station with which we desire to
talk. In other words, at one of the
two stations there will be transmits.

sent to San Francisco and another set
of wires bv which messages will be re-

other station set of wires for send,

wires for receiving messages from
Guam. which will be the next main
station eproute to the Orient in the
