CSR Wu Songru: Three Trends in Wireless Connection Technology Wireless technology has brought a lot of convenience to our communication, but people's desires and methods of communication are constantly changing and developing. In the past, we only used mobile phones to communicate, but now we have added email, QQ, MSN, facebook, twitter Wait, how can mobile phones adapt to the growing communication methods? How to integrate wireless connection technology in the future? Recently, Dr. Wu Songru, General Manager of CSR China, shared an excellent perspective on the future development of mobile phones and wireless connection technologies in an exclusive interview with Electronic Innovation Network. "In the future, the hardware functions and software of smart phones will be more matched and integrated. For example, when you fly from Shanghai to Beijing, your mobile phone can not only tell the scenic spots in the Beijing area, but also use the photos you took in Beijing. The wireless network is transmitted to your social networking sites such as QQ or Facebook, and you can also dynamically transfer your Beijing friends on your social network to you, and even send you information about your friends who came to Beijing from other places. "Dr. Wu Songru outlined this Future smart phone application scenarios, "In the future, GPS, Wi-Fi and other hardware APIs in mobile phones will be open to software designers to facilitate more convenient service functions." 1. Trend of wireless connection technology 1: Bluetooth, Wi-Fi, GPS, Bluetooth low energy, and NFC are standard for mobile phones Wu Songru emphasized that from the perspective of the development of mobile phones, mobile phones have become one of the must-have electronic products for consumers. "You may be willing to accept a forgotten wallet but cannot bear it." He used this simple fact to illustrate the importance of mobile phones , "As the mobile phone becomes a must-have for people, there will inevitably be more functions integrated into the mobile phone." Mobile phone navigation was very popular at one time, but in the end it did not become popular. Will GPS functions be used as a standard for mobile phones in the future to open applications? In response to this question, Dr. Wu Songru pointed out: "The reason why GPS mobile phones did not get hot in the past was mainly due to the unclear GPS application goals. At that time, the mobile phone's processing capacity was insufficient and the map information was insufficient. The connection technology is rich, and the types of services around mobile phone positioning are increasing. LBS (location-based services) will definitely get hot. " For example, after a user takes a picture with a mobile phone, the mobile phone can determine the location and other information of the shooting location, and can also transfer the pictures taken by the mobile phone to the user's social network through the Wi-Fi network. Of course, these wireless settings will be very simple. Such newly developed services will promote LBS applications. Second, the trend of wireless connection technology 2: wireless connection function and baseband may be difficult to integrate With the development of semiconductor technology, many mobile phone baseband processor manufacturers have proposed baseband integration of more wireless connection technologies. For this, Dr. Wu Songru does not approve, "From the perspective of chip development, in the future mobile phones may retain three chips, one Complete the baseband processing, one completes the application processing, and the other completes the processing of various wireless connection technologies. "He pointed out," Because the baseband of the mobile phone processes the main protocol of the mobile phone, the protocol standard of these mobile phones is generally slower in the update cycle, while the wireless connection technology The standard update cycle is much shorter than the mobile phone baseband standard cycle. If integrated, it will inevitably cause your integrated chip to be behind the latest version of the wireless connection version when used by system manufacturers. If you redesign the baseband chip for this reason, it will cause Unnecessary costs and workload increase. " "Therefore, many mobile phone manufacturers still choose a separate solution for baseband and wireless connection chips." He pointed out, "CSR's strategy is to integrate Bluetooth, Wi-Fi, GPS, NFC and other wireless technologies on a single chip. We will also Consider integrating the PA. In addition, these types of wireless technologies currently require different antenna support. In the future, we will also develop new antennas to support these wireless standards at the same time. " Third, the trend of wireless connection technology 3: NFC mobile phones may be hot in 2011 At present, RFID (radio frequency identification technology) is gradually gaining popularity, but one status quo is that various types of RFID technologies are currently in a state of war. For example, almost everyone has RFID-based bus cards and access control cards (for companies and residential communities). , Various payment cards, electronic passports, etc., the result is that everyone carries several RFID cards, obviously, this has caused a lot of inconvenience. Since 2008, some mobile phone operators have begun to promote NFC applications. Recently, China Mobile has begun to promote e-wallet payments, but Wu Songru believes that this technology may not be heated up until 2011. "Because although the operators have begun to promote, it may take some time for the application merchants to accept. So I estimate that this technology will be hot from 2011 to 2012." He pointed out, "For the NFC technology, CSR has made a lot of reserves and Research, we will make a big promotion when NFC is hot.

According to reports, in 2009, the production volume of Wi-Fi-enabled mobile phones, PDAs, cameras and other consumer electronic products will reach 350 million units. It is expected that by 2012, the shipment of consumer electronic devices will reach 1 billion, a compound annual growth rate. The rate reached 26%.
"NFC as an RFID technology will unify these RFID applications. In this way, you will bring so many RFID cards in the future." He pointed out, "NFC also uses passive RFID technology, which will bring great convenience when combined with mobile phones. For example, in the future, you only need to bring your mobile phone to go through customs, you can also use your mobile phone to spend in duty-free shops, take a taxi or spend in hotels, accommodation, etc. "
