Over just a few years, the world of television production, distribution, and consumption has changed dramatically. In the past, with only a few channels to choose from, viewers watched news and entertainment television at specific times of the day or night. They were also limited by where and how to watch. Options included staying home, going to a friend's house, or perhaps going to a restaurant or bar to watch a special game, show, news story, or event. When we are taking about the TV industry has now been completing and moving to the high definition from the standard definition, now the discussion is about 4K and 8K video standard.
To meet this ever-rising demand and maintain high-quality service, ST has to continually expand and improve the cellular networks that it operates. A cellular mobile network (figure 1) divides the service area into a number of cells, each of which offers a set of voice channels to carry calls to and from mobile phone users in the cell's coverage area. Each cell contains a base station where the transceiver hardware for voice channels is installed. The base stations are linked by line circuits to a central control unit called the mobile switching center (MSC), which performs various control and administrative functions, such as the activation of voice channels and the reporting of network alarms and traffic data. Each call to and from a mobile phone takes place over radio waves, at the preset frequency of a voice channel, between the mobile phone and the base station of the cell. The number of concurrent mobile calls that can be supported in any one cell is therefore constrained by the number of voice channels available in the cell. Each voice channel is associated with a specific frequency channel taken from the frequency band allocated to ST. Because the total number of frequencies available in the band is limited, the frequencies are a scarce resource that must be used efficiently. Cellular networks achieve efficient use of the allocated frequencies by allowing the same set of frequencies to be reused at several nonadjacent cells.
A new breed of security cameras can supposedly detect terrorism and crime without a human judgment call--and mass transit agencies are shelling out big bucks for the product. San Francisco's Municipal Transit Authority, which oversees the city's MUNI trains, has signed a contract with security firm BRS Labs to deploy cameras to 12 subway stations that use algorithms and machine learning techniques to spot anomalous behavior. BRS Labs is a security firm that provides behavior recognition software for video surveillance. The company's clients include government, tourist attractions, military bases, and private industry; BRS's software issues real-time text alerts when cameras detect strange behavior. Servers connected to security cameras observe locations for weeks at a time and then establish a baseline of "normal" behavior based on this timespan; anomalous activities afterwards (loitering, abandoned packages, abnormally high/low numbers of passengers) trigger an alert.
Ericsson has announced it has inked another China Mobile deal, extending its 5G radio access network (RAN) partnership and charged with 5G core components for the second phase of the telco's nationwide new radio (NR) standalone rollout. The 5G RAN partnership will extend to 17 provinces, and use the Ericsson Radio System solution. Ericsson will also provide 5G core network equipment in two major regions, covering five provinces. "Ericsson and China Mobile have continuously worked together to develop, validate, and test 5G technologies and applications," the Swedish vendor said. "This includes proactively developing products for China Mobile's 5G network deployment as well as customising 4G/5G compatible network solutions. The extended cooperation on 5G networks is a new milestone in a long partnership that spans nearly 30 years of mobile technology in China."
Video: 5G: Is all the hype deserved? It is the fourth time in history that the world's telecommunications providers (the telcos) have acknowledged the need for a complete overhaul of their wireless infrastructure. This is why the ever-increasing array of technologies, listed by the 3rd Generation Partnership Project (3GPP) as "Release 15" and "Release 16" of their standards for wireless telecom, is called 5G. It is an effort to create a sustainable industry around the wireless consumption of data for all the world's telcos. One key goal of 5G is to dramatically improve quality of service, and extend that quality over a broader geographic area, in order for the wireless industry to remain competitive against the onset of gigabit fiber service coupled with Wi-Fi.
