Podzespoły  S2-LP - transceiver Sigfox 

 

Firma STMicroelectronics wprowadziła do oferty układ transceivera S2-LP przeznaczony do pracy w sieciach Sigfox. Układ jest następcą znakomicie przyjętego przez rynek układu SPIRIT1. Zachowując funkcjonalność poprzednika ma większy zasięg, lepszą selektywność, większą elastyczność konfiguracji, a wszystko przy obniżonym poborze mocy.

Układ S2-LP zoptymalizowano do pracy w paśmie radiowym poniżej 1 GHz. Pracuje on w zakresie częstotliwości ISM dla urządzeń małego zasięgu (SRD - Short Range Devices). Dodatkowe zakresy częstotliwości są dostępne za pomocą nastaw wprowadzanych przez interfejs cyfrowy.

Dzięki zaimplementowanym mechanizmom, układ doskonale nadaje się do pracy w sieciach radiowych, takich jak Sigfox, Wireless M-Bus, 6LowPAN, zgodnych ze standardem IEEE802.15.4g. Układ pobiera prąd o natążeniu 6,7 mA w trybie odbioru danych i 10 mA w trybie nadawania z mocą 10 dBm (100 mW).

Wyposażono go menedżer zasilania, dzięki któremu może być zasilany napięciem z zakresu 1,8...3,6 V (przy sprawności menedżera 90%), co predysponuje go do zastosowania w urządzeniach zasilanych bateryjnie. Do układu sa dostępne trze zestawy ewaluacyjne: STEVAL-FKI915V1, STEVAL-FKI433V1 oraz STEVAL-FKI868V1.

Aplikacje docelowe są związane głównie z IoT, systemami alarmowymi, inteligentnymi urządzeniami pomiarowymi, inteligentnymi budynkami, monitorowaniem parametrów itp.

iPhone 7 is beating iPhone 8 according to sales research

It has been reported that Apple’s older iPhone 7 models are outselling the iPhone 8s and iPhone X that launches early November. Most of the time the new editions of iPhone have sold faster but it is not true in this case. According AT&T the last week its third-quarter postpaid handset upgrades were fewer by nearly 900,000 from a year ago, and brokerage Jefferies attributed it to weak iPhone 8 demands. “Many respondents indicated that a meaningful portion of customers are buying iPhone7 in lieu of the new iPhone 8, given the lack of significant enhancements in the new phone.” KeyBanc analyst John Vinh wrote in a client note. więcej na: www.dailytech.com

IBM beats revenue estimates; hints at sales growth

IBM shift to newer businesses such as cloud and security services helped it beat analysts’ quarterly revenue estimates, and the technology major hinted at sales growth after nearly six years of declines. Shares of the Dow component rose nearly 5.1 percent to $153.93 in extended trading on Tuesday. IBM has been focusing on cloud, cybersecurity and data analytics, or what the company calls its “strategic imperatives”, to counter a slowdown in its legacy hardware and software businesses. Revenue from these businesses climbed 11 percent to $8.8 billion in the third quarter ended Sept. 30, accounting for about 46 percent of the company’s total revenue. więcej na: www.reuters.com

Volvo is reinventing its performance brand to compete with Tesla

Volvo announced that it would transform its Polestar performance sub-brand into an all-electric Tesla competitor. "Polestar has confirmed the company’s first three models, a new purpose-built production facility in China and a new, customer-focussed route to market with all-inclusive subscription-based services that will set a new industry benchmark for performance car buyers," Volvo added. Polestar's vehicles have been impressive - we've tested the wagon at Business Insider - but the company now thinks that shifting the brand to an all-electric identity is the way to go. The first vehicle - called a "halo for the future Polestar brand" by Volvo - will be dubbed "Polestar 1" and be a gas-electric hybrid two-door cranking out 600 horsepower. więcej na: www.businessinsider.com

Samsung striving for OLED panel orders from China

Samsung Display is striving for OLED panel orders from China-based mobile device vendors, but will be facing competition from its China-based rivals such as BOE Technology and Tianma Micro-electronics, according to industry sources. Samsung's OLED panels are already being used for its own-brand smartphones, as well as Apple's iPhone X. The Korea-based vendor is vying aggressively for OLED panel orders from China-based smartphone brands, but is aware of the potential customers' preference for China-made panels, the sources indicated. LG Display is another competitor of Samsung in the OLED panel field, but Samsung regards its China-based rivals as a major threat when it comes to orders from China, the sources noted. więcej na: www.digitimes.com
