In North Korea there is relatively little access to the Internet due to the governments' fear of political instability that might accompany the benefits of access to the global Internet. The U.S. trade embargo is a barrier limiting Internet access in Cuba. Access to computers is a dominant factor in determining the level of Internet access.
Municipal wireless networks go far beyond the existing piggybacking opportunities available near public libraries and some coffee shops. The basic premise of carpeting an area with wireless service in urban centers is that it is more economical to the community to provide the service as a utility rather than to have individual households and businesses pay private firms for such a service.
Femtocells are an alternative way to deliver the benefits of fixed–mobile convergence (FMC). The distinction is that most FMC architectures require a new dual-mode handset which works with existing unlicensed spectrum home/enterprise wireless access points , while a femtocell-based deployment will work with existing handsets but requires the ...
Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". When they do transmit, nodes transmit their packet data in its entirety.
Wi-Fi positioning systems may give very exact positioning, in urban areas with high Wi-Fi density - and depend on a comprehensive database of Wi-Fi access points. Hybrid positioning systems are increasingly being explored for certain civilian and commercial location-based services and location-based media , which need to work well in urban ...
Building automation is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, Access Control, Security Systems, and other interrelated systems through a Building Management System (BMS) or Building Automation System (BAS). The objectives of building automation are ...
Battle Realms' gameplay is like many other real-time strategy games. There are several factions which all have various types of available structures and units to produce. Unlike other real-time strategy games though, the basic worker units (peasants), which are used for resource gathering and construction, also act as the base unit to be upgraded into military uni
Upstream signals are combined using a multiple-access protocol, usually time-division multiple access (TDMA). Ethernet point-to-point. Point-to-Point Protocol over Ethernet (PPPoE) is a common way of delivering triple-and quad-play (voice, video, data, and mobile) services over both fiber and hybrid fiber-coaxial (HFC) networks.
