wirelessness
chapter 4 p61
contemporary wirelesses is framed by a large-scale communication shift to the medium of electromagnetic waves
Maxwellian physics
By 1900, many different relations of connection, transfer, proximity, and influence were imagined around electromagnetic or wireless waves
Sungook Hong (2001) in his history of wireless invention
Isabelle Stengers
Electromagnetic oscillation is an event whose scope could be measured by multiplicity of its interpretations.
There are some common elements to problem, such as how to create a continuous signal(periodic waveform), how to propagate it effectively(antenna design), and how to pick up and amplify the signal at a distance.
In contrast to wired media, as the 2007 IEEE 802.11 standard states, wireless is "a medium that has neither absolute nor really observable boundaries"(IEEE 2007, 23)
p66 The sheer density of wireless transmissions creates fresh problems of regulation, interference, competition, and overload.
p.66 Air as Algorithmic Envelope
The air interface is a term for that part of a wireless or mobile telephone network that lies between the antennae of a device and a base station. It is an elusive interface,…
however, is synthesized by technical processes expressed in algorithms.
How to Make a World Hang Together: Noise
p70. The juxtaposition of different components constructs a signal envelop or composite waveform that is open in certain ways and heavily closed in other ways. Information is coded in a sequence of steps, but these steps take account of each other. Information is encoded a number of times to allow different relations to be entwined with other.
p76 A waveform produced by FFT is "conscious of itself" to the extent that the date stream entering at the start of the process has been parceled in such as way as minimize the effects of their inevitable collisions with and alteration by other signals in a given setting. In the ways it spaces and times the signal, the algorithm imprints into the waveform a certain awareness of possible encounters as well as variations in direction and speed typical of urban life and mobilities. Any contemporary sense of media streaming or constantly-on communications in the city relies on such differential quotients and tendencies.
p78 The algorithm dating from 1967 (Viterbi) is widely used in telecommunications networks to maintain the sequence of information flows. It has become a fundamental element in commercial wireless, satellite, and space communications. Andrew Viterbi, a now retire telecommunications engineer, designed the algorithm and started a company (Qualcomm 2005) that designs and fabricates semiconductors based around the algorithm. In telecommunications applications, these chips enable satellite, cellular phone, and wireless networks to communicate despite high levels of electromagnetic noise.
If the FFT is like a courier company that resorts to bicycle couriers in downtown areas, the Viterbi algorithm is like the recipient of a deluge of partly addressed parcels trying to work out who they are meant for, and which was sent first.
Chapter 5 Acting wirelessly: From Antenna to Node Database
p122 although the equipment had been designed to cover distances of around 100 meters, people began attaching new antennae that increased the range of wireless networks.
p123 Elevation is what allows Wi-Fi signals to stretch great distances. One recurring trait of antenna builders is their pursuit of rooftops, upper stories of buildings, high towers, and long poles.
