The market strategy adopted by TI, an important AP provider of smartphones, for its own product OMAP has made the industry realize the intensity of the 4G market in advance. Due to TI's lack of CDMA baseband technology, under the trend of high chip integration in the future, the advantages of OMAP will disappear. So, people can't help but sigh that the giant is so far away from the market. Enterprises want to gain a place in the future 4G market, and the baseband product line has become the basic configuration.
Yan Chenwei, vice president of mobile computing product market at Qualcomm Technology, pointed out that with the continuous evolution of network technology, "multi-mode multi-frequency" has become an industry consensus. LTE and 3G develop together, and 3G / LTE terminals that support multi-mode and multi-frequency are more in line with the user's habit of using wireless Internet and the development needs of operators. At this point, the development roadmap of operators, terminal manufacturers and chip manufacturers is consistent.
He added that Qualcomm is the earliest chip manufacturer in the industry to propose the concept of "multimode" and the industry's first to introduce a 3G / LTE multimode single-chip solution. At the same time, all Qualcomm LTE chipsets also support TDD And FDD system. "Intelligent terminals using our chips can enable operators to seamlessly switch to LTE services while retaining compatibility with their existing 3G networks, so that users can get a more consistent experience. For example, the Snapdragon S4 MSM8960 integrates the use of The 28-nanometer Krait CPU and Adreno 225 GPU also integrate high-pass modulation and demodulation solutions that support all 2G / 3G / LTE standards. Based on this processor, partners can develop smart phones that meet the needs of all operators around the world. At the time, Samsung Galaxy S III was released by AT & T, Sprint, T-Mobile, Verizon Wireless and US Cellular at the same time. Based on the same processor Snapdragon S4 MSM8960, it supports LTE, HSPA + dual carrier and other networks of five operators. Take the Snapdragon S4 MSM8930 sampled at the end of the year as an example. The MSM8930 processor is the world ’s first single-chip solution for the mass-market smartphone market with integrated LTE modem, supporting LTE TDD and FDD-LTE, UMTS, CDMA and TD-SCDMA , For three operators in China. In terms of application processors, this processor also integrates the well-received 28-nanometer Krait CPU, etc. Components.
As the industry leader, Qualcomm began to lay out the 4G market early, aiming to maintain its dominance in the 3G market in new markets.
Zhang Daijun, president of STMicroelectronics Ericsson China, also said that consumers are looking for devices that enable them to achieve network access no matter when and where they are. The multi-mode LTE chip is backward compatible with various other accesses, ensuring that consumers can access wireless broadband services all over the world. This is very important for the evolution of the wireless market. Because LTE has many advantages in terms of high-speed data transmission rate, packet transmission, and low latency, operators hope to deploy LTE networks to increase their network capacity to meet the needs of the rapid growth of data services, thereby bringing users a better experience . However, for end users, adapting to a new technology is not an overnight task. Therefore, multi-mode LTE chips can not only support existing network access, but also support LTE network access. Deployment is crucial.
"In addition, according to a report from M Research, there will be 38 LTE bands worldwide by 2015, and I believe this number will continue to grow. The LTE chip platform that supports multiple bands will help LTE develop globally. Demand. In order to meet the consumer's ubiquitous connection demand, multi-mode chipsets that can support all mainstream access technologies including 2G, TD-SCDMA, HSPA + and 4G LTE FDD / TDD will become the main trend. " He added, "Our Thor M7400 solution is specifically prepared for the LTE market. Compared with traditional LTE chips, it is a revolutionary and innovative modem solution, which also requires intensive testing and certification worldwide. At present we have entered To the final stage of these tests, the M7400 is currently being evaluated by multiple customers. It can help terminal equipment manufacturers develop terminal products that can access the global LTE / HSPA + network environment and are stylish and power-efficient. This way , Users can not only perform high-speed Internet browsing in their own country through the terminal in their hands, even roaming in other regions High-speed Internet access. "
The multi-mode and multi-band LTE baseband chip focuses on the global network adaptability, on the other hand, it carries the important expectations of the enterprise for the 4G market. At the same time, it also increases the difficulty of admitting the industry, hoping to enter the industry. Enterprises need to do enough technology accumulation and market layout.
