According to a report by Japan’s Kyodo News on May 23, Sony’s president Yoshida Kenichiro’s smartphone business, which was losing money on the 23rd, said that “the camera function will be used to enhance the competitiveness of goodsâ€, negating some observations of exiting the market. He also looked at the fifth-generation mobile communication system (5G) that is expected to be commercialized in the near future, expressing his view that this is a strategically important business. Yoshida accepted an interview with Kyodo.
The operating profit of the Sony mobile business, which accounted for more than half of the smartphones, fell to a loss of 27.6 billion yen (about 1.6 billion yuan) in fiscal year 2017. It is also expected to lose 15 billion yen in FY 2018. Many Japanese manufacturers have withdrawn from the smartphone market, and Sony's global market share may be less than 3%.
Yoshida said that in order to continue and strengthen the smart phone business, it will promote cost reduction, and intends to integrate production, parts procurement and sales with other products such as TV sets.
Yoshida pointed out that "5G communication technology is likely to be added to all products", emphasizing the intention to commit to product development.
However, due to technical and cost reasons, it is not widely used. In recent years, RFID technology has developed by leaps and bounds. With the development of large-scale integrated circuit and network communication technology, RFID technology has entered the commercial application field, and began to develop from the initial low frequency (125kHz) and high frequency (13.56mhz) to uHF (860 ~ 960MHz) and microwave. RFID technology has become one of the most promising information technologies in the new era because of its unique advantages showing great development potential and application space. In both low and high frequency bands, China has independently developed RFID chips in accordance with ISO14443 A, B and ISO15693 standards, which have been successfully applied in major projects such as city bus all-in-one card and second-generation resident ID card. However, in the uHF and microwave field, China started late, technology and products are still relatively short. In this context, this paper studies the design of 915MHz rf card reader. The system can be applied to vehicle monitoring, remote control, telemetry, access control system, identity identification, non-contact radio frequency smart card, wireless 485/232 data communication, safety and fire prevention and other fields.
