Taiwan ’s 4G bid is over. For the benefits of 4G, so far there have been big bosses shooting questions, but the global development of 4G is already a predictable fact. With the construction of base stations in succession, next year can be said to be the first year of global 4G takeoff. And as terminal devices equipped with 4G specifications will gradually become the mainstream, all chip manufacturers are all rubbing their hands and preparing to make a big turn through 4G. Hong Cenwei, vice president of research at Gartner, the research institute, analyzes that next year the 4G LTE chip battle will still be a "big four small" situation. Qualcomm will maintain its leading position, but MediaTek and other "four small" manufacturers are catching up.
MediaTek will launch the first LTE solution by the end of the year, and the LTE system single chip is expected to be launched in the middle of next year. Facing the global competition situation of 4G LTE chips, Hong Cenwei pointed out that Qualcomm still holds the leading position in the global 4G LTE chip market next year, followed by MediaTek, followed by Intel, Broadcom and Marvell.
He estimates that Qualcomm's global 4G LTE chip market share will still be as high as 80% to 90% next year. Even though MediaTek has a better strategic position in the Chinese market, it will have a 50% chance in the local market.
Hong Cenwei estimated that this year's global 4G LTE chip shipments will be about 100-200 million, next year is expected to grow to 200-300 million, of which North America is the largest market, the Chinese market has just started, shipments are estimated at 4000 Ten to fifty million. Moreover, judging from the opening status of bids such as China Mobile, China's 4G chip market shipments or amount next year should still be dominated by Qualcomm.
However, he analyzed that although MediaTek lags behind Qualcomm, it is still the company with the faster progress among other 4G chip manufacturers.
As for the future of 4G development, Hong Cenwei pointed out that the most complete deployment of LTE infrastructure is the United States and South Korea, but if evaluated by growth rate, China has the steepest growth curve from scratch. In addition, he also bluntly said that the challenges that 4G may encounter in the future are that telecom operators and communication service providers (CSP) may not be directly proportional to investment and recovery.
According to Gartner data, by 2015, CSP will invest 34% of total capital expenditure on 4G LTE infrastructure, but by then only 7% of the world ’s users may adopt 4G LTE specifications; even by 2016, mobile communication data traffic There will be a compound growth of 70% in adulthood, but it is estimated that about 40% of the 3.5 billion smartphones in the world will remain in 3G in 2017. In addition, 4G user charges in the United States and South Korea have shown a downward trend. In the future, charges may even fall to the same level as 3G.
What's worth noting is that the market is discussing heated "5G" specifications. Hong Cenwei laughed and said that he can't see it now. It is a "distant thing." At least it will take another 3-5 years before standards can be born. Despite the unpredictable changes in the technology industry, 4G has just started, and some people shouted that they should preempt 5G, which also highlights the fact that officials and practitioners are eager to get out of the predicament.
Domestic communication, 4 g module in addition to support two kinds of LTE FDD LTE/TD - LTE standard, also compatible with 2 g / 3 g down, support td-scdma/WCDMA/EDGE/GP/GSM/CDMA1X/EVDO mode. The data service downstream rate can reach up to 100Mbps, the uplink rate can reach up to 50Mbps, providing customers with high-speed Internet access and wireless data connection and other functions. In addition to providing high-speed data access, it also provides voice, SMS, communication book and other functions, which can be widely used in notebook, tablet, touch screen communication devices, smart phones, video surveillance, multimedia mobile phones and vehicle equipment and other terminal products and vertical applications. Today, I will introduce you to what is 4G module and how to use 4G module.
What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
What is the 4G module How does the 4G module work
4G module, also known as 4G transmission module, 4G communication module, 4G LTE module. It is a kind of hardware loaded to the specified frequency band, the software supports the standard LTE protocol, and the software and hardware are highly integrated modular products, with good compatibility, fast communication speed, large amount of communication data, wide network spectrum, communication flexibility and other characteristics, widely used in electric power, environmental protection, finance, industrial automation and other fields.
The working principle of 4G module
It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Through high-speed networking, the 4G module transmits all terminal business data and equipment operating status to the business center in real time. Through the management monitoring platform, the terminal equipment operating status can be monitored in real time and equipment faults can be timely checked. The efficiency has been greatly improved in many aspects such as operating cost, operation scale and service timeliness. Suitable for shared massage chair, public charging pile, vending machine, vehicle system, environmental monitoring, power remote monitoring and other industries.
