A mobile phone is an electronic device that allows users to communicate via cellular networks. These networks are composed of specialized base stations, known as cell sites. Cellular networks provide full duplex communication. When a user moves from one cell to another, the phone’s link is automatically switched to the cell with a stronger signal. Cellular phones are useful for making calls and receiving text messages. But how do they work? Let’s look at a few of the most popular types of mobile phones and the technologies they use.
Cell phones are important socializing tools. They foster emancipation from parents. They are personal telephones, which parents cannot use. This enables teenagers to develop their sense of self and reinforce their contact with peers and people outside the family. However, they are also a target for high-tech crime. The following guidelines help to prevent the occurrence of high-tech crimes involving mobile phones. The first step in preventing cell phone-related crimes is to educate people about the security requirements of cell phones. Then, providers can set up thresholds for billing that will not allow users to exceed that level of security.
A battery is essential to modern mobile phones. First commercialized in 1991 by Sony and Asahi Kasei, a lithium-ion battery is now an integral part of many devices. Next, a third generation (3G) system was launched by NTT DoCoMo in Japan in 2001. It was based on the WCDMA standard. High-speed packet access, or HSPA, is a family of standards that allows UMTS networks to have higher data transfer speeds.
In addition to the battery, mobile phones have other components that are crucial to their functionality. For instance, mobile phones contain circuit boards that contain Analog-to-Digital (A-D) and Digital-to-Analog (DA) conversion chips. These chips translate incoming signals and audio signals to make the phone work. Generally, these chips are rated at 40 MIPS, which means millions of instructions per second. Besides handling signal manipulation, they also coordinate other functions on the board.
Cloned phones are stolen and used to make fraudulent calls using someone else’s account. Then, the fraudster can clone the phone’s ESN and MIN, which are transmitted to the network. Cloning involves analyzing the transmissions of the phone and copying the data that the phone sends to the network. This method is highly effective as it allows the fraudster to make calls on the victim’s account.
Research on smartphones should examine the extent to which these devices are endorsed by other factors. In some cases, the relationship between mobile phone use and problematic emotional reactions may be better understood by considering general psychopathology, such as anxiety or depression. There are a number of other factors that may be at work when determining if smartphone use is a part of a broader psychopathology, including addictiveness. Therefore, more research is needed to understand the connection between mobile phone use and the emotional responses that arise from it.
Several authors support Griffiths (2013) by suggesting a move away from the term “addiction” to describe problematic smartphone use. They note that many studies involving the smartphone use of adolescents and young adults are based on inadequate study designs and suggest that the term “problematic use” be used instead. These authors recommend the use of terms such as “problematic use” and “problematic use instead of “addiction” in order to avoid confusing the two terms.
