Suppose we have a low-gain (1.5) antenna at both the receiver and transmitter sites, the receiver needs 10 μV into 50Ω, and the transmitter can supply 100W. At a 100-km distance, what is the highest frequency at which this link can be established? Useequation (3.48)in Problem 3.15....
VS is a coupled VM, comprising a normal VM and another one called Locator Bot (LoBot), which is responsible for security services. LoBot is instantiated and managed by a management center, called Private Virtual Infrastructure Factory(PVIF), which is outside all CNs (Krautheim, 2010). Sign ...

H.262 is applied in broadcasting, satellite, digital television, and so on. 2.4 H.263 H.263 [62], introduced by ITU-T in 1996, is suitable for narrowband communication channels under 64kb/s. It is developed based on H.261 and has better compression performance and a lower bit rate. H...
Transducers can be used in VR systems to help create a richer virtual world. They can provide an accurate representation of the real world, such as an application where the user flies over terrain. They can collect data (sometimes acquired by satellite) to create a realistic view of the eart...
(IP) address will be assigned to the user's computer as inFig. 1. The user will type the uniform resource locator (URL) of the remote Web server on his/her Internet browser. This URL will then be sent to the ISP. The ISP's computer is the one that actually contacts the remote ...
The round-trip time for a laser between the GEO satellite and a ground station at the speed of light, 3×108m/s, is (2×35,785×103m/3×108m/s)= 0.238s. From a communication point of view this delay of 0.238s can be extremely important in many practical applications such as atele...
