To explore the potential of Ka-band to support mobile satellite services, the Jet Propulsion Laboratory (JPL) has initiated the design and development of a Ka-band land-mobile terminal to be used with the Advanced Communications Technology Satellite (ACTS). The planned experimental setup with ACTS is described. Brief functional descriptions of the mobile and fixed terminals are provided. The inputs required from the propagation community to support the design activities and the planned experiments are also discussed.

Abstract: In this paper, we will present the process to access the computers and handle them with the help of android mobile phones. As well as access the Android Mobile by using a Web Browser. This process is implemented by using a Socket and to access the android mobile “NANOHTTPD” is used. So to work on this, we must install server on our computer and also Android devices must also run the server and must connected with Wi-Fi/Hotspot network. In this the user can access & perform operation through the range of Wi-Fi platforms such as windows. There is event-handling function used in this so as to support clicking and using keyboard. Whereas to access android mobiles through your Web-browser the LAN connection is needed to be set up.

The possibility to provide multimedia services over a wide area using small mobile terminals represents a challenging task. This task is even more challenging especially if high frequency bands are used and high service availability is required, considering that the atmospheric conditions are very severe and geographically variable within a wide area. The use of high frequencies is necessary to provide wideband services at high data rate for a large number of users and the link availability has to be comparable with that provided by other systems working at lower bands. In the frame of the Advanced Communications Technologies and Services program of the European Union a team of thirteen partners is working since September 1995 on the design of a satellite system named SECOMS (Satellite EHF COmmunications Multimedia Services) (Losquadro and Vatalaro, 1995; Losquadro, 1996). The system aims at providing multimedia services by means of GEO satellites utilising set‐top or palm‐top terminals working respectively at Ka‐band (20/30 GHz) and at EHF‐band (40/45 GHz). Within the SECOMS project the problems mentioned above have been studied in depth and the main system parameters have been finalised. This paper aims at a description of the main system characteristics of the SECOMS project and suggesting a design approach for satellite systems providing multimedia services to mobile users. The proposed approach consists in providing an adjustment (static or dynamic) of the satellite EIRP among the spot beams to get the same link availability within the coverage area using the same terminal, considering that the distribution of rain fade statistics depends on the location. To this aim several technical solutions can be adopted.

In this paper, we propose a PIFA based multiband internal antenna that can support seven frequency bands. The antenna is designed to operate at GSM (Global System for Mobile Communications, 880-980 MHz), PCS (Personal Communication Services, 1880-1990 MHz), UMTS (Universal Mobile Telecommunications System, 1.9-2.17 GHz), WiBro (2300-2390 MHz), Bluetooth (2.4-2.48 GHz), S-DMB (Satellite-Digital Multimedia Broadcasting, 2.630 ~ 2.655 GHz) and WLAN (Wireless Local Area Network, 5.16 ~ 5.5 GHz) frequency bands. Multiple frequency bands have been realized by using slots and quarter-wave length resonating strips. A matching stub and multiple short circuiting strips are utilized for improving impedance matching across the targeted frequency bands. A prototype antenna is fabricated and characterized by measuring return loss and radiation patterns. Comparison of the measured and simulated results is given in the paper.

A low-cost high-gain front-end amplifier has been developed at 2.5-GHz frequency for use in RDSS (radio determination satellite services) mobile terminals. The RDSS system allows an accurate positioning with the possibility of serving a large user population using the spread-spectrum modulation. Such an amplifier, built on 0.8-mm PTFE board, provides a low noise figure, a 31-dB gain and good input and output matching on the 16-MHz bandwidth allocation. All the results have been obtained using low-cost commercially available devices. © 1993 John Wiley & Sons, Inc.

This paper evaluates the effects of Rayleigh fading, shadowing, and spatial distribution of the Mobile Terminals (MTs) on the operating performance of Slotted Aloha (S-Aloha) used as a Random Access Channel (RACH). This paper also evaluates the capture probability in a channel exhibiting Rayleigh fading, shadowing, and the effect of spatial distribution of the MTs. In addition, this work presents a different version of the steady-sate probabilities of the Markov chain of S-Aloha considering capture effect. This article simulates the stabilization of S-Aloha by utilizing an algorithm that dynamically controls the retransmission probabilities. Finally, this paper presents a numerical analysis of these simulations and identifies the operating of parameters that have shown to degrade system response.
