FireChat
FireChat was a proprietary mobile app, developed by Open Garden, which used wireless mesh networking to enable smartphones to pass messages to each other peer-to-peer via Bluetooth, Wi-Fi, or Apple's Multipeer, without an internet connection. Though it was not designed with the purpose in mind, FireChat was used as a communication tool in some civil protests. FireChat is now discontinued. The official URL displays a 404 error page, and apps have not been updated since 2018. History The app was first introduced in March 2014 for iPhones, followed on April 3 by a version for Android devices. In July 2015, FireChat introduced private messaging. Until then, it had only been possible to post messages to public chatrooms. In May 2016, FireChat introduced FireChat Alerts, which allowed users to "push" alerts during a specific time and in a specific place. This feature was added for the benefit of aid workers doing disaster relief and stemmed from a partnership with the city of Ma ...

Smartphone Ad Hoc Network
Smartphone ad hoc networks (SPANs; also ''smart phone ad hoc networks'') are wireless ad hoc networks that use smartphones. Once embedded with ad hoc networking technology, a group of smartphones in close proximity can together create an ad hoc network. Smart phone ad hoc networks use the existing hardware (primarily Bluetooth and Wi-Fi) in commercially available smartphones to create peer-to-peer networks without relying on cellular carrier networks, wireless access points, or traditional network infrastructure. Wi-Fi SPANs use the mechanism behind Wi-Fi ad-hoc mode, which allows phones to talk directly among each other, through a transparent neighbor and route discovery mechanism. SPANs differ from traditional hub and spoke networks, such as Wi-Fi Direct, in that they support multi-hop routing (ad hoc routing) and relays and there is no notion of a group leader, so peers can join and leave at will without destroying the network. Spans are useful under circumstances when the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Mesh Networking
A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network.Chai Keong Toh Ad Hoc Mobile Wireless Networks, Prentice Hall Publishers, 2002. A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent. If nodes constantly or frequently move, the mesh spends more time updating routes than delivering data. In a wireless mesh network, topology tends to be more static, so that routes computation can converge and delivery of data to their destinations can occur. Hence, this is a low-mobility centralized form of wireless ad hoc network. Also, because it sometimes relies on static nodes to act as gateways, it is not a truly all-wireless ad hoc network. Mesh clients are often laptops, cell phones, and other wireless devices. Mesh routers forward traffic to and from the gat ...

Abandonware
Abandonware is a product, typically software, ignored by its owner and manufacturer, and for which no official support is available. Within an intellectual rights contextual background, abandonware is a software (or hardware) sub-case of the general concept of ''orphan works''. Museums and various organizations dedicated to preserving this software continue to provide legal access. The term "abandonware" is broad, and encompasses many types of old software. Definitions of "abandoned" vary, but in general it is like any item that is abandoned – it is ignored by the owner, and as such product support and possibly copyright enforcement are also "abandoned". Types ;Commercial software unsupported but still owned by a viable company: The availability of the software depends on the company's attitude toward the software. In many cases, the company which owns the software rights may not be that which originated it, or may not recognize their ownership. Some companies, such as Bor ...

Financial Times
The ''Financial Times'' (''FT'') is a British daily newspaper printed in broadsheet and published digitally that focuses on business and economic current affairs. Based in London, England, the paper is owned by a Japanese holding company, Nikkei, with core editorial offices across Britain, the United States and continental Europe. In July 2015, Pearson sold the publication to Nikkei for £844 million (US$1.32 billion) after owning it since 1957. In 2019, it reported one million paying subscriptions, three-quarters of which were digital subscriptions. The newspaper has a prominent focus on financial journalism and economic analysis over generalist reporting, drawing both criticism and acclaim. The daily sponsors an annual book award and publishes a " Person of the Year" feature. The paper was founded in January 1888 as the ''London Financial Guide'' before rebranding a month later as the ''Financial Times''. It was first circulated around metropolitan London by James Sherid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IOS Software
iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that powers many of the company's mobile devices, including the iPhone; the term also includes the system software for iPads predating iPadOS—which was introduced in 2019—as well as on the iPod Touch devices—which were discontinued in mid-2022. It is the world's second-most widely installed mobile operating system, after Android. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. It is proprietary software, although some parts of it are open source under the Apple Public Source License and other licenses. Unveiled in 2007 for the first-generation iPhone, iOS has since been extended to support other Apple devices such as the iPod Touch (September 2007) and the iPad (introduced: January 2010; availability: April 2010.) , Apple's App Store contains more than 2.1 million iOS appli ...

Mobile Ad Hoc Network
A wireless ad hoc network (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers in wired networks or access points in wireless networks. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes forward data is made dynamically on the basis of network connectivity and the routing algorithm in use. In the Windows operating system, ad hoc is a communication mode (setting) that allows computers to directly communicate with each other without a router. Wireless mobile ad hoc networks are self-configuring, dynamic networks in which nodes are free to move. Such wireless networks lack the complexities of infrastructure setup and administration, enabling devices to create and join networks "on the fly". Each device in a MANET is free to move independently in any direction, and will therefore change it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
End-to-end Encryption
End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecom providers, Internet providers, malicious actors, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation. End-to-end encryption is intended to prevent data being read or secretly modified, other than by the true sender and recipient(s). The messages are encrypted by the sender but the third party does not have a means to decrypt them, and stores them encrypted. The recipients retrieve the encrypted data and decrypt it themselves. Because no third parties can decipher the data being communicated or stored, for example, companies that provide end-to-end encryption are unable to hand over texts of their customers' messages to the authorities. In 2022, the UK's Information Commissioner's Office, the government body ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
