Background Service QoS in Integrated UMTS-HSDPA and WLAN Ad Hoc Networks with Various Inter-Domain Routing Protocols
Abstract: AbstractThe Next Generation Network (NGN) allows the service providers to extend the coverage and capacity of existing network towards rural and hot spots area with large variety of services. Integrated UMTS-HSDPA and WLAN Ad Hoc Networks is most eligible NGN’s under this category. The integrated network offers a large variety of services e.g. conversational, streaming, interactive, and background class. This paper focuses on asymmetric best-effort service belonging to the background …

Development of Bandwidth Enhanced Microstrip Patch Antenna for UMTS Application
Abstract: In this article, a low-profile microstrip patch antenna for UMTS application is presented. A wideband coaxial probe-fed slotted microstrip patch antenna has been simulated on IE3D software to give a wide bandwidth of 31.34% and tested successfully. The simulated and measured results in terms of return loss show good agreement.

Performance Analysis of Network Based Cellular Positioning Techniques in UMTS Networks
Abstract: In the current scenario location estimation is a very challenging field in case of UMTS networks, as the utility is very high in the LBS application with respect to various aspects. So, performance analysis of cellular positioning techniques is carried out in this paper using three mostly used network based techniques likely RSSI, TOA & AOA, where the nodes are assumed to be static at the time of computation of …

Integrated Networks: A Survey
Abstract: AbstractUniversal Mobile Telecommunication System (UMTS) networks are solution for high speed voice and internet services with ubiquitous coverage. Ericsson Mobility Report (EMR) has claimed that subscriptions of UMTS/HSPA were 2.1 billion in 2015 and predicted that these are expected to reach 3.1 billion by the end of 2021 [1–3]. They support 384 kbps maximum data rate in downlink and 128 kbps data rate in uplink over a 5 km typical …

Design and Analysis of Dual Band Triangular Slotted Microstrip Patch Antenna for GPS and WLAN Application
Abstract: AbstractIn this paper, design of a dual operated microstrip patch antenna is presents. The dual-operation frequencies are chosen for UMTS/GPS and WLAN bands. A microstrip square patch antenna is designed which is excited by a microstrip line feed from the bottom of the antenna. An epoxy glass FR4 material is used as a substrate in the designing of antenna. The antenna is first modified in inverted U-shaped design to operate …

Design and Performance Analysis of Multi-Standard CMOS LNA Using Switched Capacitor and MIM Capacitor in 180nm Technology
Abstract: Low noise amplifier (LNA) is terribly important block in designing broadband receivers for wireless broadband communications. Being the primary active element in receiver chain it creates larger demand for LNAs that are smaller, consume less power, and provide sufficient gain, low noise and high compact design. The projected LNA is extremely integrated with low noise figure having wide calibration range with improved RF power handling system and acquires less space …
