Dual Mode Mobile
{{Unreferenced, date=April 2016 Dual-mode mobiles refer to mobile phones that are compatible with more than one form of data transmission or network. Dual-Mode Phone A dual-mode phone is a telephone which uses more than one technique for sending and receiving voice and data. This could be for wireless mobile phones or for wired phones. There are three types of dual-mode phones. Network Compatibility Mobile phones containing two types of cellular radios for voice and data. These phones include combination of GSM and CDMA technology. They can be used as a GSM or CDMA phone according to the user's preference. These handsets are also called global phones. An example of this is the Samsung SCH-A790. These dual-mode handsets are compatible with both GSM and CDMA networks and are essentially two phones in one device. Such phones make sense in those countries that have both GSM & CDMA networks or international CDMA roamers who want to keep a single handset with two numbers on it. Most ...

Telephone
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from el, τῆλε (''tēle'', ''far'') and φωνή (''phōnē'', ''voice''), together meaning ''distant voice''. A common short form of the term is ''phone'', which came into use early in the telephone's history. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a ...

Router (computing)
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node. A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. The most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. More sophisticated routers, ...

WiFi
Wi-Fi () is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide visitors with Internet access for their mobile devices. ''Wi-Fi'' is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term ''Wi-Fi Certified'' to products that successfully complete interoperability certification testing. the Wi-Fi Alliance consisted of more than 800 companies from around the world. over 3.05 billion W ...

GAIT (wireless)
GAIT (an acronym for the GSM-ANSI-136 Interoperability Team) is a wireless standard developed in 1999{{cite press release , publisher=GSM Association , date=2001-01-12 , title=GSM GLOBAL ROAMING FORUM TO INCLUDE TDMA TECHNOLOGY , url=http://www.gsmworld.com/news/press_2001/press_releases_0.shtml , access-date=2006-06-17 , url-status=dead , archive-url=https://web.archive.org/web/20060616063949/http://gsmworld.com/news/press_2001/press_releases_0.shtml , archive-date=2006-06-16 that allows cross-operation of mobile telephone technologies. Phones compliant with the GAIT standard can operate on either contemporary GSM networks, or the legacy IS-136 Digital AMPS, TDMA and Advanced Mobile Phone System, AMPS networks found extensively throughout North America. Since GAIT phones are interoperable over several types of networks, users could operate their phones in a much larger area of North America compared to phones that used only the GSM standard.

Pixel 2
The Pixel 2 and Pixel 2 XL are a pair of Android smartphones designed, developed, and marketed by Google as part of the Google Pixel product line. They collectively serve as the successors to the Pixel and Pixel XL. They were officially announced on October 4, 2017 at the Made by Google event and released in the United States on October 19. On October 9, 2018, they were succeeded by the Pixel 3 and Pixel 3 XL. History In early March 2017, Google's Rick Osterloh confirmed that they would bring a "next-gen" Pixel smartphone later that year. He stated it would "stay premium" and that there would be no "cheap Pixel". Google originally intended to use HTC to manufacture both their 2017 flagships, but later shifted to LG to manufacture the bigger Pixel 2 XL. The unreleased device that was supposed to be the Pixel 2 XL under the codename "Muskie", was later re-developed by HTC into the HTC U11+.

Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by Modulation#Digital modulation methods, modulating one or more carrier wave signals to encode digital information, while the receiver Demodulation, demodulates the signal to recreate the original digital information. The goal is to produce a Signal (electronics), signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
