With the latest developments in video coding technology and fast deployment of end-user broadband internet connections, real-time media applications become increasingly interesting for both private users and businesses. However, the internet remains a best ...
Capacity is often studied under constraints on the channel input signals. This paper investigates the behavior of capacity when constraints are placed on the channel output signal (as well as generalizations thereof). While such a change in perspective lea ...

In recent years, wireless Internet service providers (WISPs) have established thousands of WiFi hot spots in cafes, hotels and airports in order to offer to travelling Internet users access to email, web or other Internet service. However, two major proble ...
IEEE 802.11 is probably the most widely used, medium access control protocol in current wireless networks. In the Wireless LAN (i.e., single-hop) setting, its performance is by now quite well understood. However, in the multi-hop setting where relay nodes ...
Wireless Mesh Networks (WMNs) represent a new and promising paradigm that uses multi-hop communications to extend WiFi networks: By deploying only one hot spot (directly connected to the Internet) and several transient access points (TAPs), an Internet Ser ...
A novel DAC architecture based on a sub-binary radix converter is presented. By calibrating digitally the nonlinear sub-binary converter, it is possible to use it as a high-precision, high-resolution digital-to-analog converter. The analog part of the new ...

The automatic configuration of Access Points (APs) is a new subject, since the Wi-Fi technology, which underlies hotspots by a wireless local area network, appears on the world market in 2001. The first market relevance has been in 2002. APs channel assign ...
The rapid growth of WiFi over the past two years reveals the willingness of the Wireless Internet Service Providers (WISPs) to develop this technology and the interest of the users in this new service. However, the lack of unified roaming slows down the de ...
We consider the problem of full-duplex video transmission over the Internet, under real-time delay constraints. In this work we present the design of a complete communications system, whose salient features are: (a) a soft real-time transport protocol, who ...
