The objective of this paper is to demonstrate how the latest wireless standards and technologies may overcome the digital divide in education in the developed and developing worlds. The concept of the digital divide is discussed in the traditional socio-economic sense and expanded in terms of the learner's location, age, culture and background. It is important that we understand the full extent...

One challenge of wireless networks integration is the ubiquitous wireless access abilities which provide the seamless handover for any moving communication device between different types of technologies (3GPP and non-3GPP) such as Global System for Mobile Communication (GSM), Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications ...

Mobile WiMAX (Worldwide Interoperability Microwave Access) requires the re-authentication of mobile stations as they change from one base station to another. IEEE 802.16e uses the Extensible Authentication Protocol (EAP) for authentication and key management. This requires about 1000 ms, therefore, it could not support mobile WiMAX applications such as video conference. In the present paper, we...

This paper deals with the design and implementation of Secure Home Automation using Raspberry Pi for mobile devices that leverage mobile technology to provide essential security to our homes and associated control operations. The proposed home security solution hinges on our novel integration of cameras and motion detectors into web application. Raspberry Pi operates and controls motion detecto...

Human populations are increasingly exposed to microwave/radiofrequency (RF) emissions from wireless communication technology, including mobile phones and their base stations. By searching PubMed, we identified a total of 10 epidemiological studies that assessed for putative health effects of mobile phone base stations. Seven of these studies explored the association between base station proximi...

WiMAX is the worldwide interoperability for microwave access, to provide business and consumer world wireless broad band services in metropolitan area networks. It has a target range of 31 miles and a target transmission rate exceeding 100 Mbps. Mobile WiMAX is an OFDM based technology for deployment which allows multiple-antenna operations to be performed on vector-flat sub carrier. Fixed WiMA...

the explosive growth of the Internet from last few years has led to an increasing demand of high speed, everywhere Internet access. Broadband Wireless technologies are increasingly gaining popularity by the successful global deployment of the Some technology like as Wireless Personal Area Networks (BluetoothIEEE 802.15.1), Wireless Local Area Networks (WiFiIEEE 802.11n), and Wireless Metropolit...

The purpose of this paper is to design and fabrication of an annular ring slot patch antenna with short stub (ARSPA) for mobile applications Digital Cellular System (DCS) (1.711.88) GHz, Personal Cellular System (PCS) (1.85 -1.99) GHz, and Universal Mobile Telecommunications System (UMTS) (1.71-2.17) GHz. Return loss and bandwidth are studied with respect to short stub location. By using short ...

F1.1 Terrestrial Fixed Radio Systems Active studies of rain attenuation characteristics are continuing for developing broadb quasi-millimeter wave band. It is based on a trend that the use of microwave band gradually from the fixed use to the mobile use. Results of those stu and systems above has been changing dies will be reflected in developing a multipoint-to-multipoint system, a mesh type w...

IEEE 802.16 Worldwide Interoperability for Microwave Access (WiMAX) is an emerging broadband wireless communication standard used as a model of transmission and high speed Internet access. 3G Long Term Evolution (LTE) is the leading standard for wireless communication of high-speed data for mobile users. In this report we compare the performance of voice and video applications over WiMAX and LT...
