Wi-Fi is a popular technology that al over a computer network‚ including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards".[A device that can use Wi-Fi can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater

Infineon (GSM) and Broadcom (EGPRS)‚ thus ending a long-standing strategy that required the use of the Nokia 2G protocol stack in handsets that bear the Nokia brand name. Technically‚ Nokia has been using Qualcomm’s protocol stack and chipsets for CDMA2000/EV-DO handsets but this is generally done through a third-party ODM. Nokia also expanded its 3G supply chain to include STMicroelectronics. Given the complexities of integrating the software on a solution other than a TI DSP‚ Nokia would not give

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short‚ such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed‚ mobile‚ and portable applications‚ including two-way radios‚ cellular telephones‚ personal digital assistants

3G (Third Generation) Wireless Vs 2G (Second Generation) Wireless Abstract In my research paper‚ I will be defining the difference between 2G wireless and 3G wireless. It will consist of the history of both 2G and 3G network. 2G networks were built mainly for voice data and slow transmission. Due to rapid changes in user expectation‚ they do not meet today’s wireless needs. Cellular mobile telecommunications networks are being upgraded to use 3G technologies from 1999 to 2010. Japan was the

Abstract : Mobile Telephone History This article describes how mobile telephones‚ for decades a near dormant technology‚ became the dynamic and perhaps most important communication tool of our lives. Commercial mobile telephony began in 1946. The cellular radio concept was published in 1947. But only since 1995 have mobiles become low cost‚ rich in features‚ and used world wide. We first examine mobile telephony’s early and bulky beginnings. Next‚ the long journey to analog cellular. Finally‚
