1 TARIFF SIM card-based antenna extension system and method Technical Area 5 The invention allows for the use of a SIM card without any modification to the existing hardware of the mobile device. an antenna extension system that improves signal performance and It is related to the method. State of the Art Today, the most common methods used to improve signal quality on mobile devices are: At its core, this involves multiple antenna structures within the device and the algorithms that operate in conjunction with them. Especially with 4.5G. And MIMO (Multiple Input Multiple Output) technology, used in 5G systems, allows multiple 15 It aims to improve signal quality and data speed by transmitting and receiving data through the antenna. along with beamforming algorithms, the signal is directed from the base station to the user. It is directed. On the device side, antenna selection (antenna diversity), power control algorithms, and Connection quality is optimized using adaptive modulation techniques. However, one of the biggest limitations of these systems is that they are entirely dependent on the device's physical antenna. It depends on the design and hardware layout. In other words, a device's antenna performance... It is determined during the production phase and cannot be improved by the user afterwards. Especially in small sizes. Because antenna size and placement are limited in form factor devices (such as thin phones) Performance also remains limited. This situation can lead to connection drops or failure at low signal levels. This leads to significant performance declines. In addition, one of the signal amplification solutions used today is external. These are repeater (signal repeater) devices. These systems take the weak signal present in the environment and... It reinforces and then spreads it again. However, this approach requires additional hardware, is costly, and every 30 It is not practical for the user. Furthermore, there is a risk of causing interference to the network if installed incorrectly. It can be found there. On the algorithmic side, cellular networks constantly switch between cells based on signal quality. (handover), power adjustment and frequency selection are performed. However, these algorithms are based on the physical characteristics of the device. 35 It remains limited in situations where it receives a weak signal. In other words, no matter how good the algorithm is, 2 If the antenna cannot receive a sufficient signal, system performance decreases. This is especially true in enclosed spaces. This is a common problem in fields or areas far from base stations. Another significant shortcoming of current solutions is the lack of flexible customization options on the user side. The problem is the lack of a mechanism. When the user wants to increase the signal strength of their device, either 5 They have to change devices or use external equipment. Software optimizations, on the other hand... It cannot exceed physical limits. Current communication systems use MIMO, beamforming, antenna diversity, and Similar algorithms provide high performance when a sufficient signal level is received. It can demonstrate this. However, the physical signal level is critically low. The effectiveness of these algorithms is limited in certain scenarios. The fundamental technical problem that arises as a result of all these shortcomings is this: mobile devices Antenna performance is fixed and limited; in poor coverage conditions, current algorithms rely on physical 15 It is unable to compensate for the signal deficiency, and this results in connection drops, low data speeds, and This leads to problems such as high latency. The application with the number CN203690482U was revealed as a result of technical investigations.
