Definition
4g remains defined as the last standard of cellular wireless generations in the 21st century, 4g is an advanced development of 3g and 4g, and it is a brief description of advanced international mobile communications. It is worth mentioning that 4g is one of the criteria that can create radical and comprehensive solutions to internet protocols, and through its multimedia facilities that flow heavily to users regardless of time and space and are more accurate in terms of data quality than previous generations.
4G Objectives
It should remain noted that the 4g has come to achieve some objectives, the most important of which is compatibility with the opportunity for the user to obtain a standard that corresponds to the quality of service and the rates it requires, and therefore wireless broadband access, as well as the application of an efficient spectral system, the creation of a high-capacity network, the provision of data rates of at least 100 Mbps, and the creation of a high-quality multimedia generation of service.
4g Features
The 4G standard is based solely on the IP package. It features an open-range Internet platform through some offers, adding that all 4G stations will remain implemented based on a range of second-generation to its infrastructures, and one of the most prominent technologies provided by 4G is Flash OFMD WiMAX and HC-SDMA.
4g Components
the 4g standard consists of several features: access charts:
Access technologies used in wireless communications coincide with the development and development of wireless standards generation after generation. So access technologies have achieved a marked increase in both the ability to use and absorb in addition to their efficiency. Hence, access schemes vary between ages as the first generation relied on time and FDMA. IPv6, this component in the fourth generation, is quite different from that of the third generation; only the fourth generation relies on converting packages without circuits. The third generation depended on two infrastructures: turning courses and beams towards the network, respectively. Advanced antenna systems, it is worth mentioning that the adoption. And the performance of wireless communications depends intuitively on the antenna system in the messaging and transmission of data. Multiple antenna technologies are considered the most efficient and accurate system in achieving the 4g standard.
Strengthening The 4g Signal
Internet users always seek a more robust internet at all times and places. At present, the network is the focus of users’ attention to get it at full strength, so the search begins to look carefully for ways to strengthen its signal for a better service. And some methods can remain used to improve the 4g signal, as follows:
So, use external antin. And can be used by placing it outside the house’s walls or on the house’s roof, for example. Use a network booster; a small-scale technical device used to strengthen the network and amplify its signals within range. Use the inner antin, requiring the user to place it inside the house’s walls to efficiently broadcast the internal network inside the house. The original cable, which remains a link between external and internal antin devices, is a network booster.
