Inconsistencies within the various areas of telecommunications policy make for rich debate. For example, cable Internet service providers are not obligated to provide competing service providers with wholesale pricing for access to customers, while incumbent local exchange providers (specifically regional Bell operating companies) must provide such Internet access. Several authors have proposed...

Large constellations present unique challenges to space operators in a variety of ways, but due the increasing interconnection between satellites within these architectures, cybersecurity is critical concern. The potential for massive shutdown such system through network attack could have long-term consequences environment. This article describes role that legal structures play managing risks a...

ENUM" is an Internet protocol designed to enable one to be reached on an array of different electronic communications devices by means of just one number – a telephone number. ENUM effectively bridges the telephone and Internet worlds by placing telephone numbers from the International Telecommunication Union (ITU) Recommendation E.164 public telecommunication numbering plan into the Internet D...

T he notion that our nation’s critical infrastructures are highly interconnected and mutually dependent in complex ways, both physically and through a host of information and communications technologies (so-called “cyberbased systems”), is more than an abstract, theoretical concept. As shown by the 1998 failure of the Galaxy 4 telecommunications satellite, the prolonged power crisis in Californ...

Satellite transmissions have an important role in telephone communications, television broadcasting, computer communications, maritime navigation, and military command and control. Moreover, in many situations they may be the only possible communication set-up. Recent trends in telecommunications indicate that four major growth market/service areas are: messaging and navigation services (wirele...

We consider the problem of assigning transmission powers to the nodes of a wireless network in such a way that all the nodes are connected by bidirectional links and the total power consumption is minimized. We present a distributed protocol, obtained by extending a connectivity protocol recently appeared in the literature. The new extended protocol is obtained by using in a local, distributed ...
