lora has the characteristics of low speed, low power consumption and low cost, but the ota upgrade of lora's internet of things terminal has not been provided with a high-quality solution. based on this, abup and asr have worked together to customize the ota differential upgrade solution for lora, taking advantage of their respective technical advantages.
shanghai ella than intelligent technology co., ltd. (english abup) day everyone would fly with rapid science and technology (shanghai) co., ltd. (asr) after signed a strategic cooperation agreement after months of research and development, recently launched based on asr6501 lora sip chip difference ota remote upgrade solutions, booster lora wireless communication technology in the application of internet of things fall to the ground and intelligent agile iterations, cheer for lora ecology.
about lora
lora is a kind of lpwan technology, which adopts wireless modulation/demodulation technology based on css (chirp spread spectrum). the reception sensitivity reaches -148dbm, and the transmission distance can reach more than 5km in sub-1ghz ism band. lora is also the abbreviation of long range.
lora provides users with a remarkable long-distance, low-power, secure data transfer mechanism. public and private networks built with lora technology offer greater coverage than existing cellular networks, making it easier for devices using lora to join existing lora networks to service those battery-powered iot scenarios.
lora features: long distance, low power consumption, multi-node, low cost, anti-interference characteristics, low rate, suitable for small data transmission. lora technology includes lorawan protocol and lora protocol. in fact, lorawan refers to the networking protocol at the mac layer, while lora is just a physical layer protocol.
lora networking applications
lora adopts tdm networking, namely time division multiplexing, which can be starnet. in practical applications, it is often used in point-to-point, ad-hoc network and lorawan networking, which can be flexibly used in combination with internet of things application scenarios.
asr low power lora integrated chip asr 650x
since september 2018, asr has launched three lora series integrated chips, asr650x, which adopt advanced sip scheme. the chip integrates the ultra-low power mcu and the latest lora rf chip sx1262, which supports the most complete lora band and is the lowest cost lorawan integrated chip on the market. with the characteristics of ultra-low power consumption, ultra-small size, high sensitivity and high transmitting power, it is the leader in the field of lpwan chips.
integrated with lorawan, linkwan and alios, the chip can be widely used in smart meters, smart cities, smart security, smart agriculture, smart logistics, smart communities, smart home and other internet of things applications.
abup customizes ota remote upgrades for lora
lora has the characteristics of low speed, low power consumption and low cost, but the ota upgrade of lora's internet of things terminal has not been provided with a high-quality solution. based on this, abup and asr have worked together to customize the ota differential upgrade solution for lora, taking advantage of their respective technical advantages.
the scheme can realize the flexible application of lorawan scene, greatly reduce the size of the firmware of lora terminal (usually for about 5% of the original firmware), can save lora terminal side flash occupancy resources, improve the efficiency of lora network of upgrade, greatly saves lora network upgrade download time, produced in the process of the upgrade and power consumption.
"asr iot has been developing all kinds of iot chips since its inception," said shidao yang, senior r&d manager of asr iot. asr650x lora series of chips previously launched were recognized by a large number of partners once they came to market. at present, the chips have been implemented in a number of internet of things fields. at the same time, asr, as a company with ip license of lora chip, is also in the intensive research and development of lora soc chip of asr, which will soon meet the market. after that, asr will launch various lora chips for different applications. at present, the innovative application layer in the domestic lora market is not unique, and product upgrading and optimization are indispensable. i believe that the cooperation between asr and elaby in lora ota can solve the worries of many lora terminal manufacturers in product application.
as for the close cooperation between the two parties, wan xuejing, vice president of marketing of araby, said, "araby has been focusing on ota technology development and marketing. ota differential technology with core patent has been widely applied in thousands of internet of everything terminals. lora can develop rapidly in the world, thanks to its technical advantages and scenario-based application ability. asr is a key promoter of lora in china. this time, asr and asr can work together to develop ota differential upgrade under lora. the cooperation between the two parties will surely accelerate the application of ota technology in all walks of life of lora internet of things, give lora terminal manufacturers the ability to upgrade and evolve, and promote the intelligent process of lora ".
the asr6501-based module, rf-al42uh, will greatly facilitate the sustainable development of the lora ecosystem with ota technology.
