Classically difficult positioning environments have always called for some augmentation technology to assist the Global Positioning System (GPS). “Locata” offers augmentation, and even replacement, to GPS in such environments. However, like any other system relying on wireless technology, a Locata positioning network faces issues in the presence of RF interference (RFI). This problem magnifies ...

Multiplier is an important block of wireless communication system. In many applications there is a need to mix the signals of different frequencies or signals of different types, which emphasises the use of mixers or multipliers for different RF applications. MOS analog multiplier with less number of transistors which can operate at ISM Band frequency with high linearity is proposed. An ISM ban...

This paper presented a modified efficient inductive powering link based on ASK modulator and proposed efficient classE power amplifier. The design presents the external part which is located outside the body to transfer power and data to the implanted devices such as implanted Microsystems to stimulate and monitoring the nerves and muscles. The system operated with low band frequency 10MHZ acco...

This paper presents a new algorithm IBLUEREA, which enables the reconfiguration of Bluetooth scatternet to reduce interference. IBLUEREA makes use of the complex model comparing ISM environment efficiency. The mechanism envisages the use of the assessment of the probability of successful (unsuccessful) frame transmission in order to take a decision concerning the coexistence of technologies whi...

Introduction: Near-infrared spectra of pyroxenes have distinct absorption features at approximately 1 and 2 µm. The positions of these features are dependent on the composition of the pyroxene [1,2]. Pyrox-ene spectra have been observed on the Martian surface [e.g., 3], and at high spectral resolution by the ISM imaging spectrometer [4] on board the Phobos-2 spacecraft in 1989. Previous researc...

The 2.4 GHz ISM band provides an attractive medium for developing tethered free applications based on current and proposed wireless standards. Since the ISM band is a shared spectrum allowing unlicensed operation of wireless services, coexistence between the wireless services needs to be considered to ensure performance requirements are maintained. A general method for evaluating coexistence is...

This white paper presents information related to the IEEE 802.11b Wireless Local Area Networking standard (Wi-Fi) and the Bluetooth Wireless Personal Area Networking standard. Both Wi-Fi and Bluetooth products utilize the unlicensed 2.4 GHz ISM band. Due to their dependence on the same band, the potential for interference exists. This documents describes how products based on these technologies...
