更强大！谷歌FI运营商服务推出下一代短消息功能rcs_我的网站

A | 北京时间1月15日上午消息，据美国科技媒体《边缘报道》报道，本周，谷歌宣布在谷歌FI网络上推出RCS聊天信息服务。

B | 谷歌还宣布，它正在优化漫游用户的数据速度。    A "super fog" in Louisiana has caused a multi-car pileup on Interstate 55 near New Orleans, Louisiana, after severely lowering visibility, according to police.The crash, involving dozens of cars, occurred on Monday morning due to heavy fog conditions, according to Louisiana State Police. A long stretch of Interstate 55, a 24-mile-long highway over Lake Pontchartrain near New Orleans, is expected to be closed "for the foreseeable future," police said.Interstate 10 and Interstate 310 were also closed as a result of the crash, police said. Louisiana Gov. John Bel Edwards confirmed the accident in a statement Monday that there were fatalities in the crash, but did not say how many people were killed or injured.For hours after the crash, emergency crews worked to clear debris from both northbound and southbound lanes, according to state police.The super fog was caused by smoke from marsh fires burning in the region combined with dense fog developing in the area early Monday morning bringing extremely low visibility. In some spots, visibility was near zero, creating dangerous driving conditions.Super fogs typically form when condensed water vapor mixes with the smoke and moisture released from damp organic material smoldering from a nearby fire, such as brush, leaves and trees, according to the National Weather Service. Visibility can be lowered to less than 10 feet as a result, according to the NWS.This has been occurring in the region over the past several mornings, with the location of the densest fog and most dangerous conditions varying day to day, forecasts show.Super fogs can be especially dangerous when they develop near and over highways. The localized nature of the weather phenomenon means that visibility conditions can worsen rapidly within a very short distance, which can lead to a hazardous combination of sudden low to near-zero visibility and vehicles traveling at a high speed on a highway.The very limited visibility then hinders a driver's ability to react to changing conditions on a roadway.The National Weather Service issued a dense fog advisory for much of southeastern Louisiana on Monday morning, including from Baton Rouge to New Orleans.Over the past several days, the National Weather Service has been warning of the threat of dense fog during the early mornings in the region that would be worsened in some areas by nearby marsh fires. State police advised drivers to use their low-beam headlights if they can't see at least 500 feet in front of them.The fog dissipated by mid Monday morning, and all fog alerts have since been canceled.While areas of smoke will continue to be possible in the area as various marsh fires continue to burn, fog is not forecast to be a major issue Monday night, as weather conditions will be less favorable for fog development.Morning fog is not uncommon this time of the year for the region, but more than 86% of the state is currently battling extreme drought conditions, which is elevating fire danger. This could mean more instances of super fog in the coming days and weeks as cooler temperatures settle in, but the drought and wildfire risk persist.In addition, devastating drought and wildfire conditions continue to impact Louisiana. More than 60% of the state is now categorized at exceptional drought, the highest category of concern, according to the U.S. Drought Monitor. Just three months ago, 0% of the state was listed under exceptional drought."The combination of wildfire smoke and dense fog is dangerous, and I want to encourage all Louisianans in affected areas to take extreme caution when traveling," Edwards said in a statement.State troopers are working to notify families and investigate the exact cause of the crash, according to state police.It is unclear how many fatalities and injuries occurred as a result of the crash. The St. John the Baptist Parish Sheriff's Office directed media requests to Louisiana State Police.Additional information was not immediately available. Louisiana State Police did not immediately reply to ABC News' request for comment.。此前，RCS在Verizon、Sprint和T-Mobile网络上获得的支持有限。谷歌正在更广泛的手机上提供RCS服务。

C | 该服务支持google pixel、moto g6、lg v35、lg g7和android one moto x。如果用户下载google消息应用程序，rcs也可以用于其他手机。其他移动通信网络只在少数手机上启动了rcs聊天，包括Verizon的Pixel3和T-Mobile的三星。奇怪的是，谷歌FI在这一领域落后于其他运营商，因为谷歌一直是RCS的重要推广者。尽管google fi的用户数量很小，但谷歌此举可能会促使其他运营商今年加速接受rcs。rcs是下一代取代短消息服务，大多数运营商默认称之为“聊天”。rcs提供了许多用户可以从消息客户端获得的功能：更高分辨率的图像和视频、WiFi消息发送、输入指示器、读取指示器以及更强大的群组聊天功能。rcs不提供端到端加密技术来保护用户隐私。然而，谷歌很快将不会在Android上提供任何这样的消费者应用程序：allo正在逐渐淡出，而hangout更多地转向企业产品。此外，谷歌还宣布将提高漫游用户的数据速度。两年前，谷歌与三家公司合作，为旅行者提供LTE网络。

D | 目前，在谷歌FI覆盖的33个国家中，用户可以获得更快的速度。和过去一样，google fi对这些数据的使用不收取漫游费，因此对于需要频繁国际旅行的人来说，这是最佳选择。
