“ Millions of messages going in all directions, crossing and recrossing one another, as is done every day by wire, are probably an impossibility by wireless telephony. Weird and little-understood conditions of the ether, static electricity, radio disturbances, make wireless work uncertain, and such a thing as twenty-four-hour service, seven days in the week, can probably never be guaranteed. In radio communication all must use a common medium, and as its use increases, so also do the difficulties. The privacy of the wire is also lacking with the wireless telephone. ”

“ The interoperability and interdependence between multiple devices is becoming a common characteristic because people are trying to build their own Internet of Things by getting all their smart devices to be connected in the cloud. The IoT needs a standard to interact with other devices and this standard must enable software for easier interaction. ”

“ I don’t know who started the wireless game in Montclair, but I do know that it was a long time after I was exposed to the wireless germ that it took and I was interested enough to listen in to the news that was flashed out by ship and shore stations. Nearly all fellows begin wireless by seeing some of their pals monkeying with the apparatus, and no wonder, for wireless has a kind of fascination about it that makes a deep appeal to not only boys but men. ”

“ The laws relating to the uses of wireless, and especially the rights of governments to the sole use of the systems in case of war, are in a confused condition, but eventually order must come from this chaos as it did in the history of the telephone and telegraph.
Wireless has brought the possibility of communication between any two individuals, no matter where they may be situated, within the realm of fact. A severing of communication with any part of the world will be impossible. ”

“ And the same advantages that the radio telephone has on land prevail as well at sea for transmission of messages by cable is a frightfully expensive thing. Not only is the laying of such a line difficult, dangerous, and costly, but to maintain it is expensive and hard as well. In time of war it is particularly at a disadvantage since the cable can be cut and all communication with the outside world easily severed. Wireless, on the other hand, is not dependent on any such extravagant equipment. It finds its own way through air, water, and earth with very little help from us ”

“ In the first place, wireless telephony is now, and probably always will be, very expensive. Where the wire will do it is the more economical. There are many limitations to the use of the other for talking purposes, and it cannot be drawn upon too strongly by the man of science. ”

“ Most PBBS systems are connected to a network of packet radio based boards. Many amateurs use 1200 bps, but speeds of up to 56,000 bps are being used on higher frequencies (the 420-450 MHz band in the United States) . Hams are working on real-time digitized voice communications, still-frame (and even moving) graphics, and live multiplayer games. In some countries, there are also gateways available to terrestrial public and commercial networks, such as CompuServe, and Usenet. Packet radio is demonstrated as a feasible technology for wireless extension of the Internet. ”

“ As a result of exhaustive researches, too extensive to describe here, it has been ascertained that the function of the wireless telephone is not to do away with the use of wires, but rather to be employed in situations where wires are not available or practicable, such as between ship and ship, and ship and shore, and across large bodies of water. The ether is a universal conductor for wireless telephone and telegraph impulses and must be used in common by all who wish to employ those agencies of communication. ”

“ The merciful Lord has arranged that when there are less than twenty-four vibrations a second, or more than forty thousand they escape us. But a wireless instrument, on the contrary is spared nothing, having attached to it a detector that catches every sound and an amplifier that magnifies it and makes it discernible to our ears. When you listen in on a wireless telephone you will be uncontestably conscious of this. Also you must take into consideration that the waves sent out by a radio transmitter are not choppy, irregular ones such as you get when a stone is tossed into the water ”

“ But if in future I must have a wireless telephone at my bedside I shall be no more isolated than I should have been had I remained at home. Pretty soon there will be no place under the sun where a man can go and get peace and quiet. The Maine woods will be full of radio outfits and the tops of distant mountains in touch with the stock market. Even an aeroplane carries its wireless. ”

“ Meanwhile, the radio amateur to whom this book is addressed may have his share in the joys of wireless. To get all of these good things out of the ether one does not need a rod or a gun--only a copper wire made fast at either end and a receiving set of some kind. If you are a sheer beginner, then you must be very careful in buying your apparatus, for since the great wave of popularity has washed wireless into the hearts of the people, numerous companies have sprung up and some of these are selling the veriest kinds of junk. ”

“ When I was chief wireless operator on the Andalusian I met operators from all over the world. Once when I was in London I scraped up an acquaintance with a young Swede and he had about half-a-dozen pairs of head-phones that he had picked up in different countries. Telephone receivers for wireless work are like violins in that no two of them are alike and you can’t tell by their appearance what they are really worth; like violins, too, telephone receivers improve with age provided the magnets are made of the right kind of steel and properly tempered. ”

“ Wireless telegraphy is possible because mankind has discovered instruments which act as electric ears or eyes, catching and recording vibrations that had hitherto remained undetected.
The earliest known form of wireless telegraphy is transmission of messages by light. A man on a hill lights a lamp or a fire. This represents his instrument for agitating the ether into waves, which proceed straight ahead with incredible velocity until they reach the receiver, the eye of a man watching at a point from which the light is visible. ”

“ Wireless telephones will not only transmit the speech more clearly and distinctly, but have the further advantages that the initial cost is very much lower than that of wire lines, the maintenance is almost nil in comparison, the depreciation is smaller, the number of employees required is less, and a break-down is limited to the inside of the station, where it could be quickly remedied by the substitution of a duplicate spare piece of apparatus. ”

“ Mr. Petersen, the chief engineer, I know quite well,” the head of the Copenhagen police suggested.
In consequence an introduction was next day effected between the two wireless engineers, who sat together in the big wireless station at Lyngby, outside Copenhagen, the note of which with its call-signal, “O.X.A.,” is well-known to every wireless man. There they thoroughly discussed the whole matter.
“We experience no interference,” said the Danish engineer. “But we use the six-hundred mètre wave in transmission, while you say ‘M.S.K.’ is under five thousand mètres. ”

“ In days when wireless telegraphy is occupying such a great deal of the world’s attention, it is not likely to cause much astonishment in the reader to learn that wireless transmission of speech over considerable distances is an accomplished fact. ”

“ In these progressive times it is only reasonable to expect that some attempt would be made to utilise the ether-waves for other purposes than that of telegraphic communication, and already many clever minds are at work trying to solve the problems of the wireless control of torpedoes and airships, wireless telephony, and, last but not least, the wireless transmission of photographs. ”

“ The question proceeded from Tom.
“This craft has wireless. When the bunch comes back to life they can flash a message to the plantation telling them to be on the lookout for us. That is, if they guess where we’ve gone, and there isn’t much doubt that they will.”
“Right you are, Ned Bangs,” agreed Jack; “but I guess with what we know about wireless it won’t take over and above long to fix the Tarantula’s apparatus so that it won’t be any more good than a bunch of junk.” ”

“ It is vain to undertake to 'cut in on' a series of wireless impulses made up of four different rates of vibration. The probability of getting the secret of the combination is as slight as of your solving the number combination on the door of a safe. From experiments I have concluded that 151 this individualization will allow the transmission of several million different messages. It is interesting when you think that one world telegraphy plant would have a greater capacity than all the ocean cables combined. ”

“ Wireless telephony, like wireless telegraphy, but to an even greater extent, is peculiarly suited for the conveyance of marine intelligence. Wireless telephony occupies a unique position in this regard-no operator is required. The additional expense of an operator is an objection to the wireless telegraph in many cases, and forbids its installation. Anybody can operate the wireless telephone. It is also much quicker-words can be spoken more rapidly than they can be put into Morse signals and translated. ”

“ A serious drawback to the operations of wireless lies in the fact that the stations are liable to get mixed up and some one intercept the messages intended for another, but this is being overcome by the adoption of a special system of wave lengths for the different wireless stations and by the use of improved apparatus. ”

“ Jack had succeeded in attaching a bell to the wireless apparatus, which, while it did not sound powerfully when a wireless wave beat against the antennæ, yet answered its purpose so long as they were in the vicinity of the wireless room. Jack had hopes, in time, of perfecting a device which would give a sharp, insistent ring and awaken even the soundest sleeper. The boy knew that on many small steamers only one wireless operator is, from motives of economy, carried. When such an operator is asleep, therefore, the wireless “ears” of his ship are deaf. ”

“ Marconi tackled it all the instruments that were needed for telegraphing without wires were at hand but no one had quite caught on how to use them.
Nearly every one thinks, too, that it is far more wonderful to send wireless messages than it is to send messages over a wire; but this is not the case at all, though both, I trow, are wonderful enough. When we say a message is sent by wireless we do not mean, by a long shot, that it goes from the place where it is sent to the place where it is received without anything between them to carry it. ”

“ The practical success of wireless telegraphy depends on the use of an adequate medium for the transmission of electricity. The most meagre training suffices to prevent the declaration that if wireless messages cannot be sent without apparatus they cannot be sent at all. ”

“ It is a matter of common knowledge that a large part of the important inventions in connection with wireless telegraphy have been the work of amateurs and private research and not the outcome of official brains or the handiwork of military or naval organisations. In fact we may say that wireless telegraphy itself in its inception was an amateur product. Numerous important inventions such as the crystal detector, the oscillating valve, the triode valve—have been due to private or amateur work. ”

“ We are, in other words, watching as the self‐assembled wireless net begins to cooperate thickly enough that even infrastructure builders may not have much work left to do. Combine that with ubiquitous SIP soft phones inside your PDAs, Internet tablets, laptops. Combine that with the reluctance of most people in the young generation to buy wire line telephone service anymore, and there’s a perfect storm being set up for the bandwidth merchants. ”

“ I never saw anything in all my born life with so many rules attached to it as this wireless business. It is one tangle of rules, rules, rules! You might as well be tied up in a net," fretted the man.
"There do seem to be a good many rules at first glance," returned Bob pleasantly. "However, when you examine them most of them are both necessary and wise. And after all when each radio operator knows in black and white what he can do and what he can't it is far simpler."
"I suppose so," grumbled Mr. Crowninshield.
"Besides, there are always slackers at every job," continued Bob. ”

“ The whole principle of the wireless telephone is based on the fact that sound can be transformed into electricity and then can be transformed back into sound again. I know," he said, with a smile, "that that sounds very much like saying that you can make eggs into an omelet and then get the omelet back into separate eggs again"—here there was an audible snicker from the boys—"but that is very much like what is done by the wireless, although it doesn't exactly fit the case. ”

“ Scientists attacked the problem with vigor, and various means of wireless telephony were developed, without any being produced which were effective over sufficient ranges to make them really useful.
Probably the earliest medium chosen to carry wireless speech was light rays. A microphone transmitter was arranged so that the vibrations of the voice would affect the stream of gas flowing in a sensitive burner. The flame was thus thrown into vibrations corresponding to the vibrations of sound. ”
