美国宽带就没有不让人头疼的选择。

Verizon FIOS 光纤到户上下行对等快是快，但是覆盖率差的感人。

怪不得星链有市场

美国宽带就没有不让人头疼的选择。

Verizon FIOS 光纤到户上下行对等快是快，但是覆盖率差的感人。
At&t 到现在很多地方还是电话线ADSL，下行8m上行2m。
Spectrum 300/10 500/20 1000/35 也是Cable，价格便宜甚至给固定IP。但是连接稳定性完全看人品，快三天慢三天，时快时慢又三天。

Comcast 这老流氓，有线宽带早年还限制流量，每个月好像300G？超过了限速到4M。网站里专门给你统计你每天用了多少流量。恶心的要命。

这个Comcast是不是NBC和Universal Studios的母公司

那只能说基建不行。拉光纤成本太高。

Comcast的1g网络也就30m上传，Verizon所有套餐都是上下对等。而且comcast每年涨价10刀

verizon人家也有电视

这家公司也经营有线电视，类似现在广电的宽带。

Comcast's symmetrical multi-gigabit internet test is a preview of next year's "10G' rollout

Comcast says 10G-enabled service will greatly increase upload speeds next year, but price hikes for TV and internet are already appearing on customers' bills.

Comcast announced in a press release it successfully tested a symmetrical multi-gigabit DOCSIS 4.0 connection on its live network, taking a major step toward “offering 10G-enabled services” in the second half of 2023.

In Philadelphia, where Comcast is headquartered, it connected service at an undisclosed business location using multiple cable modems and a DOCSIS 4.0-enabled 10G node. If you're wondering what 10G means, the answer is — more than 5G. As we noted in 2019, the cable industry rolled out its marketing term just in time to have something that's twice as many Gs as 5G wireless.

DOCSIS 4.0 tech should enable download speeds of up to 10Gbps with 6Gbps uploads, and Comcast said a lab test in January achieved more than 4Gbps speed in both directions.

It also potentially gives Comcast another way to earn more money from existing subscribers, which would align with Comcast's new plan to increase revenue despite customer growth that's stalled in recent quarters. Comcast has already announced to its customers it's increasing its cable and internet prices this month, with the average nationally going up by 3.8 percent. One Verge writer's bill shows a $3 bump for internet service and a TV subscription that will be more than $7 more expensive next month.

Earlier this year, Comcast announced it was working on rolling out multi-gig Internet speeds to more than 50 million residences and businesses in the U.S. by the end of 2025. The company planned on deploying 2Gbps speeds to 34 cities by the end of this month and has also given a slight bump to download speed on internet service in many areas.

The advantage of 10G tech is that it should make multi-gig speeds available for both downloads and uploads (currently, Comcast's gigabit plans include upload speeds of just 200Mbps), just as it is with fiber optic internet connections. However, for anyone considering upgrading, we should note that you will probably need another new cable modem.

Ideally, this will increase speeds for those in places where fiber isn't available, especially non-metropolitan areas. And in places that have competition, it measures closer against rivals that deliver fiber services, such as Verizon, AT&T, Google, and Frontier Communications, which are already offering some customers symmetrical multi-gigabit connections.

“We started this year with the announcement of our world-first test of 10G modem technology capable of delivering multi-gig speeds to homes and, as of today, 10G is a reality with the potential to transform and evolve the Internet as we know it,” said Elad Nafshi, EVP and Chief Network Officer at Comcast Cable. “It's been an incredible year of progress, and we look forward to continuing to refine and harden our 10G technology as we work to make this service—and all its incredible benefits—available to all customers in the years ahead.”
