北京冬奧如火如荼進行中，爭議事件也一樁接著一樁。中國滑冰女將范可新在參加冬奧女子500公尺短道競速滑冰八強賽時，被網友抓包疑似拋出「障礙物」讓對手跌倒，出奧步行為受到抨擊。

冬奧爭議連環爆，先是冬奧競速滑冰2000公尺混合團體接力項目，因美國和俄羅斯被改判違規才讓原先無緣準決賽的中國晉級奪金；現在又傳出在女子500公尺短道競速滑冰八強賽中，中國選手范可新出奧步！在比賽中和對手爭道時，她疑似故意將一個障礙物推到對手腳下，造成前方的加拿大選手查爾絲(Alyson Charles)摔倒。
但偷雞不著蝕把米，范可新自己也被摔倒的查爾絲絆倒。事後，摔倒前為第二名的查爾絲向大會提出申訴，最終晉級下一輪。而將障礙物當作「風火輪」搞破壞的范可新雖無緣晉級，但也並未受到大會處罰，引發網友熱議，瘋傳這段影片痛批「太誇張了！」「這是個熟練的動作，一定有練過」、「是瑪利歐賽車的龜殼嗎？」「不得不說，作弊者展現了驚人的精準度和協調性」、「這也太可怕了！」也有人因太常產生爭議，建議奧會可以刪除短道競速。

Helium is a decentralized, open wireless network built on a new blockchain for the physical world. It relies on a novel type of work called Proof of Coverage, and a new consensus algorithm (based on HoneyBadger BFT). The Helium Network is used to route data for long-range, lower power IoT devices that use Helium’s LongFi protocol. Helium's LoRaWAN Network is built upon 8-channel gateways. (Source: Internet)
The significant helium network expansion in recent years has resulted in a massive increase in antenna supplies.
Helium Hotspot antennas are quite useful because they allow multiple individuals to connect at the same time without affecting the connection speed. Our product line includes both durable outdoor antennas and indoor high-performance dipole antennas that are suitable for a variety of LoRa applications, including Helium hotspot support.
The following are the primary types of antennas that our company manufactures:
Indoor Antennas, often known as wi-fi antennas, resembles a "rabbit ears" TV antenna and vary in size depending on how powerful they need to be. They normally have a modest gain.
Our indoor antennas can be found here: https://ft-rf.com.tw/wi-fi-antenna
Our main products are Outdoor antennas, which comes in a variety of designs and frequency bands, from 118 Mhz to 6.2 GHz
LoRa antenna which has long-range coverage while maximizing radio spectrum are made of Fiberglass Material, Omnidirectional polarization which operates in the 890-960MHz frequency for series 915MHz LoRa Antenna (US915 LoRa), 902 MHz to 928 MHz for 923MHz (AS923 for Singapore, Malaysia, Taiwan...), 868Mhz to 870 MHz frequency for 868MHz (EU868 LoRa Antenna)
The UV-resistant fiberglass shell enables all-weather operation.
For lightning protection, it is made of copper elements and coupled to the DC ground potential.
Any type and length of cable can be terminated with a female N-Type connector / N-Male connector (Custom - please contact us for details)
