A variety of broadband wireless access technologies were investigated for improving the performance of GPS RTK systems. Compared with UHF radio modems, broadband wireless access technologies provide great advantages for RTK applications. For example, the line-of-sight condition for a radio link is not required any more except for “last mile” wireless connection (i.e., wireless connection of end...

Future access network architectures should exhibit reliability while providing broadband Internet services. Progress on research and development of reliable wired and wireless access networks is discussed in this paper. Some emerging access network architectures and their reliability issues are explained.

Infrastructure investments expansion typically adds to the productive capacity in an economy, and thus to its economic growth. Network industries account for between one–tenth and onequarter of economy wide investments (OECD 2009 B). Telecom industry is one of the network industries, and broadband is a new technology that is widely used all over the world. It is the popular mode of access to th...

of the Dissertation End-to-End QoS Provision over Heterogeneous IP and non IP Broadband Wired and Wireless Network Environments

We propose a quality of service (QoS) monitoring program for broadband access to measure the impact of proprietary network spaces. Our paper surveys other QoS policy initiatives, including those in the airline, and wireless and wireline telephone industries, to situate broadband in the context of other markets undergoing regulatory devolution. We illustrate how network architecture can create i...

This paper defines an end-to-end Billing Process Model. The processes in this model are mapped to the Telecommunication Management Network (TMN) Model. Usage Metering Interface (UMI) in the process model is defined for between Network Providers (NP) and Equipment Providers (EP). And it is designed for the BICI (Broadband ISDN Inter-Carrier Interface) environment where multiple carriers using AT...

In this paper we utilize the gamma neural model to improve the signal to noise ratio (SNR) of broadband signals corrupted by white noise. The projection of a noisy signal onto the signal subspace can not remove the noise in the subspace. A focus gamma network, when trained as a nonlinear predictor of the projected trajectory, reduces this noise further. The property of adaptive memory depth of ...

Ž . The ATM Asynchronous Transfer Mode network is regarded as effective for a multimedia telecommunication environment that enables high-speed and broadband communication. This paper reports on the system architecture and Ž . design concept of the FETEX-150 ESP Enhanced Switching Platform which has been designed as an ATM switch in a public broadband network. To track the latest ATM standards a...
