The concept of PTT (push to talk) business originated from the cluster communication technology. It was initially used on walkie talkie, and its user experience was simple and fast, and half duplex communication was adopted. PoCThat is, push to talk over cellular is a PTT service based on the cellular communication sys
Recently, I just saw a new business. PTT, push to talk (PTT), also known as one-click, implements the walkie talkie function on the mobile phone. It is to use a mobile phone with corresponding functions as a walkie talkie. It is a half-duplex communication mode. This type of mobile phone has an intercom key. After you press it, you can call other users or groups (regardless of the distance, only in the carr

Cellular Automation is closely related to the development of relevant theories and methods. On the one hand, the development of Cellular Automation is benefited from the research of relevant theories, such as the theory of logical mathematics, discrete mathematics, and computer automation, on the other hand, the development of cellular automation has also promote
Cellular automata (Cellular automaton)Cellular automata automata is a grid of cells, each of which chooses to open or close according to the state of the neighborhood. All cells follow the same rules, also known as Cellular update rules, which determine the next state of the cell based on the current state of each cell
Currently, most Windows Mobile devices have telephone and other wireless communication functions. In many cases, you want your application to interact with these communication functions. For example, you want to reduce the sound of your app playing music when the phone calls, or you need to directly perform various operations on the communication hardware. It is often difficult to develop such applications. The biggest difficulty lies in testing applications. To solve the difficulty of testing s
Similar to the architecture array, the cellular array can store data of different types and sizes. Each element is called a cell ). (1) create a cellular array Three methods: direct assignment, using the cell () function and using {} to directly create all cells in the cellular array. Instance: % 1. Direct value assignment method % assign a value to a unit in th
1. Development and application of mobile positioning technology The origin of radio location technology can be traced back to the beginning of the last century, the military demand of the Second World War and the digital cellular mobile communication system which began to be popularized in the late 80 promoted the development of the technology in military and civilian fields respectively. GPS and Loran C system are typical positioning systems, they u

The following is a detailed explanation of Wifi+cellular: In fact, the new ipad in the release of the use of the 4G network, because the foreign 4G network has been fully popularized, so directly to the previous version of the ipad 3G known as the new ipad 4G version. However, the new ipad in China, because there is no 4G network in the country, so the new ipad is divided into two versions, a WiFi version and a wifi+

Cellular Structure A chain of connected cells of two types A and B composes a cellular structure of some microorganisms of species. If no mutation had happened during growth of a organism, its cellular chain would take one of the following forms: Sample notation O = OA means that if we added to chain of a healthy organism a cell a from the right hand side, w
