In this chapter, we explore the evolution of wireless broadband networks in cities. We examine the technological alternatives for city-wide implementation, and the governance arrangements for such implementation. Several wireless infrastructure technologies, such as Wi-Fi, WiMax, and Mesh networks have quickly evolved during this century.

A completely new and different principle of 'wireless' endoscope is described. The 'contact endoscope' consists of two parts, a rod which is the optical element and a light recovery jacket. This endoscope utilizes the surrounding light, either daylight or artificial light. It allows endoscopic photography and cinematography with a magnificant of nearly

With Bluetooth components getting smaller and cheaper, we might soon integrate wireless microservers into all kinds of electronic devices. The authors explore application of a general-purpose, pluggable microserver, based on wireless application protocol and Bluetooth technology, for remote control purposes.

Miniaturization of electronic components may allow the construction of new types of endoscopes that no longer require external wires, cables, or optical fibers. Our aim was to assess the feasibility of wireless endoscopy and to construct experimental prototypes using miniature charge-coupled device cameras, light sources, microwave transmitters, and ...

Guglielmo Marconi’s radio transmission facility in Derrigimlagh Bog, Connemara, Ireland, in operation from 1907 to 1925, permits historical theorization of the forms of energetic mediation that sustain imperial economies of peripheralization. This remote facility was chosen because of its relative proximity to North America during experiments with ...

To achieve performance gains in the wireless channel, spatial diversity is employed. These higher order transmit diversity gains generally require multiple transmit antennas at the source. This requirement is not always possible in real world applications, where practical concerns limit the number of antennas a wireless device can have. Recently, a new
