Collecting the micro network news, under the new infrastructure boom, the innovation and development of communication technology is continuously upgraded, as an important supplement of 5G communications, with low power consumption, wide-area characteristics, applied to fragmentation scene demand, very suitable for the Internet of Things Low-power WAN (LPWAN) technology, which is deployed, ushered in new development opportunities. IoT Analytics data showed that LPWAN began to become a key driving force for the growth of the Internet of Things, and the number of connections in 2023 will exceed 1100 million.
LPWAN market prospects
At the same time as the explosive growth of the Internet of Things, the Internet of Things technical standards are constantly upgrading, especially in the LPWAN field, competition is extremely intense. At present, the international LPWAN-related standards can be divided into two categories. One type is LORA, SIGFOX and other technologies working in unauthorized spectrum; the other is working under the authorization spectrum, 2G / 3G / 4G cellular communication technology supported by 3GPP, such as Cat.1 / LTE-M, NB-IOT, etc. Each protocol has its own characteristics and advantages. There is no technology to apply to all Internet of Things application scenarios, it is difficult to have a unified standard in the short term.
Market Research Institutions Ovum Fourth Quarter Terrain 2019 The Low Power WAN (LPWAN) Deployment Tracking Report Display, as of the end of 2019, an authorized spectrum (NB-IOT and CAT. 1 / LTE-M) and non-authorized spectrum (Lora And SIGFOX, the global number of LPWAN deployment has reached 501, an increase of 16% year-on-year. Among them, LORA is still the most popular technology, and the non-authorized spectrum LORA technology dominates in commercial existing network deployments, which accounts almost one-third of market share (about 30.4%).
LPWAN upstream low power technology, terminal module cost decline, and the maturity of market environment, will bring opportunities for the downstream application market. The low-power consumption networked market in the future capacity, the chip is the core elements. In the world's largest LPWAN network (Lora and NB-IOT), only Semtech can provide LORA chip, the LORA chip in the Chinese market relies on imports, and 2018 Alibaba Cloud IoTed Union Technology (ASR) through SEMTECH The ASR6501 authorized to make this situation change. Later, ASR successively launched the three LORA chips and ASR6500S series system integration schemes of ASR6501, ASR6502, ASR6505 to apply scenarios, customer needs, product availability, and growth trends.
ASR launches the first domestic support LORA LORA LORA LORA LoWAN Wireless Communication SOC Chip
The natural fragmentation characteristics of the Internet of Things market determines the requirements for communication technology to present diversity. At this LPWAN market, there is no technology to apply to all Internet of Things application scenarios, which also means that users need a chip that combines a variety of LPWAN protocols to create a multi-technical integration complex application scenario.
A new generation of LPWAN chip requires architecture to achieve ultra-low power consumption, combining a variety of signal modulation techniques, increasing transmission rate, new design transmission symbol structure, enhanced signal coding technology, and improve transmission sensitivity.
As the direction of emerging wireless technology, the MCU and RF separation scheme and the SIP package form are the best pioneers before the market and application direction, and the market is getting bigger and bigger, and life is getting bigger and big. The cycle is getting longer, similar to many wireless communication chips, and the LPWAN chip is gradually moving towards SOC. Highly integrated, very low power consumption, super cost-effective SOC is an important milestone that marks LPWAN to mature.
With this mission, ASR launched the first domestic support LORA LORA low-power WAN wireless communication SOC chip ASR6601. The ASR6601 integrates a universal microcontroller and RF unit on a single chip, including RF transceivers, modems, and a 48 MHz frequency, 32-bit MCU using ARM Cortex M4 architecture. A variety of memory selection includes flash memory and 64KB SRAM, etc., built-in embedded LCD drivers, support AES, DES, RSA, ECC, SHA, SM2 / 3/4 hardware encryption. At the same time, the ASR6601 can reach the ultra high sensitivity of -148dBm, and the maximum 22dBm transmit power, while the minimum size of the QFN48 is only 6mm x 6mm. With SOC design, ASR6601 has become the current power consumption, the highest performance, lowest cost LPWAN chip, which greatly reduces the user design threshold, and help customers save a lot of time and reduce material list and operating costs, especially for large Projects for batch applications and projects that need to be customized.
On the basis of high integration, the ASR6601 also supports multiple modulation modes. Since the linear frequency range provided by the transceiver is 150 MHz ~ 960 MHz, ASR6601 can support various ISM bands. Modem Supports LPWAN Low Power Wide Area Network Table Technology LORA, so you can support LoraWan and LinkWan protocol stacks; also supports traditional modulation methods such as (G) FSK, support BPSK's send and (g) MSK's transmission and reception, and private protocols Compatible.
All of these modulation techniques have enabled ASR6601's wireless applications with greater flexibility and spectral compatibility, more in combination with a variety of networking technology coexistence in the existing Internet of Things market. Using the ASR6601 low-power WAN wireless communication module to provide ultra-long distance, ultra-low power LPWAN solution, can be largely displayed in various application scenarios in urban management, including infrastructure, streetlights, air, transportation, meter reading , Positioning, construction, etc., as well as intelligent home, energy conservation and emission reduction, environmental testing, industrial manufacturing, etc. can also be widely used.
Undoubtedly, low-power WAN technology is recovering new business models with profound changes in the Internet of Things, more innovative applications will be developed with the birth of more rich and perfect chip products. With the successful launch of ASR6601, with ASR in the IoT WiFi chip ASR550X series, IoT GNSS chip ASR530X, IOT BLE chip ASR560X, and believe that ASR will further meet different customers with powerful technical service capabilities. The demand for multi-technical application scenarios, accelerating the booming of all objects, for China's "core" dream, contributing "core" power.
