Starlink

"Starlink v2 mini deployed in orbit"

Not sure if this version will enable direct smartphone satellite internet. But the overall upgrades are still very nice.

-better phase array antennas and band for about 4x more capacity per satellite

-new argon Hall thrusters for on orbit maneuvering, about 2.4x thrust to the previous generation (170mN thrust)

Hope the full v2 experience will be arriving soon. Direct smartphone connection is a very important way of expanding the suburban area for better living quality. Infrastructures are required to build a 30~40 minutes range suburb. And among all, internet is the hardest one. Sustainable electricity and water are not that difficult with a community size over 200 houses. (closer to natural water source is preferrable) So the only thing left is internet. For a more populated area, solutions like cellular towers that's connected to the satellite instead of the fiber are viable. But suburb areas are mainly uncovered area, so no connection during commute or field work is still a huge deal. Starlink v2 seems to be the key toward this future.

"Starlink v2 迷你版已经在轨道上部署"

不确定这个版本是否支持手机直接连接卫星互联网，但总体升级仍然非常出色。

-更好的相位阵列天线和带宽，每颗卫星的容量增加了约4倍

-新的氩气霍尔推进器可用于轨道机动(低轨道需要定期推动，不然会掉下去)，相对于上一代推进器的推力增加了约2.4倍（推力为170mN）

希望完整的v2体验能够很快到来。我认为手机直连卫星，是扩大郊区生活圈 和 提高生活质量的一个重要因素。建立一个30~40分钟范围的郊区生活圈需要各种基础设施，而其中最难的是互联网。对于拥有超过200户的社区来说，可持续的电力和水的问题并不难解决。（靠近自然水源更好）所以剩下的唯一问题就是互联网。对于人口更多的地区，像将手机基站连接到卫星而不是光纤的解决方案是可行的。但郊区面积相当大，在没有网络覆盖的范围通勤 和 做什么其他维修工作是不可行的，通常会用更专门的卫星通讯设备。Starlink v2似乎是通向这个未来的关键。
