will satellites replace cell towers

Remember once your signal hits the tower it travels the rest of the way through the network on nice speedy fiber cables. He owns SpaceX and invest and fundraise for startups. Cellphones have a lag of about 90ms or less.There are also technical challenges. I think Starlink could easily dethrone mobile giants with great reception and speed around the world.

Satellite phones, on the other hand, do not rely on towers, but instead transmit signals via satellites orbiting the earth. However, there are disadvantages such as the cost of maintaining a satellite fleet, line of sight issues, and noticeable lag time for higher orbiting satellites.I Googled, and determined the round trip for a signal to go from earth to a satellite and back again is on average ~250ms. Instead of networks of 4000 to 12,000 internet satellites there could be 500,000. While broadcast-style TV is pretty do-able with satellites, any sort of interactive service is considerably handicapped by the high latency. This would reduce latency from 30 milliseconds to a little less than 10 milliseconds. Space based satellites could replace cell tower on a one for one basis.Lasers clearly can have terabit per second communication speed. Would it be possible for Starlink to replace cell towers in the next decade. 5G may need an estimated 300,000 to 400,000 NEW cell sites on top of existing towers.He fundraises for various high impact technology companies and has worked in computer technology, insurance, healthcare and with corporate finance.He has substantial familiarity with a broad range of breakthrough technologies like age reversal and antiaging, quantum computers, artificial intelligence, ocean tech,  agtech, nuclear fission, advanced nuclear fission, space propulsion, satellites, imaging, molecular nanotechnology, biotechnology, medicine, blockchain, crypto and many other areas.Disclosure: Brian has articles that give stock advice.Brian owns the Nasdaq index with funds and ETF, owns SP index, owns Tesla, Netflix, Amazon, Cisco, Alibaba, Editas, other international funds.

Doubtful. An entire space network …

Further research indicates anything above ~200ms is noticeable and distracting to users. You need to use frequencies that won't get absorbed or deflected by the different layers of the atmosphere. As 5G rolls out throughout 2020, carriers will begin releasing 5G coverage maps but probably won't show exactly where every tower is placed. If this could be done would it not be a lot easier to cover more area, with better reception than with cell towers currently used?You need different frequencies and transmission strength to communicate effectively with satellites, and even then bad weather can cut the connection.Much, much more importantly though: It's ridiculously more expensive. Cell towers have land leasing costs.

An entire space network of 500,000 could be swapped out for $60 billion.They would not need fiber because they would send multi-terabit lasers through space. If you ever plan to replace your home broadband internet with 5G, you'll most likely have a 5G cell tower down the street from your house. Satellites are a reasonable way to achieve internet access where previously there was none. Communications companies take out multi-BILLION dollar insurance when they launch equipment, which itself costs millions of dollars themselves.Even then, the lag and interference would make it far less reliable.What is interesting is the research going into cutting down the energy requirements and size of feasible Earth bound infrastructure. You think your phone's battery dies fast now, wait until it's constantly trying to connect to satellites. He may also trade options.

But draining battery and just cost seem like reasonable explanationsRelative to the price of a satellite a bit of radio equipment on a pole is really cheap. But that does not negate the fact that the available real estate must be found, then purchased or leased, properly zoned, and power and backhaul utilities run to the locations. Some frequencies will go much further, requiring less equipment.Satellites are extremely expensive - it's way cheaper to just pepper the landscape with towers than it is to launch a single satellite.Second, data throughput through a satellite is way slower. I can say this because I heard about the latest mission of SpaceX- Starlink. Why Satellite Internet Is the New Space Race. If it could be done with less, it would be done with less.You could probably cut down on the Earth side requirements by building huge arrays of gigantic satellites; effectively do the same thing as we do to hear the Voyager probe, just in reverse. These new cells may not need full-size towers, however, because they may be placed on buildings and will be located in more densely populated areas. He could easily lay more position on Tesla and big tech (amazon, apple, google, microsoft, nvidia etc…). Remember once your signal hits the tower it travels the rest of the way through the network on nice speedy fiber cables. With satellites it would be all radio all the way, and not even fast radio at that.Also battery life would be abysmal and the phones would likely have to be larger to accomodate a high-power satellite transmitter (take a look at some satellite phones and notice how bulky they seem to be - a lot of that is just ruggedization because they're built for harsh environments, but a good portion of it is also to accomodate the radio).New comments cannot be posted and votes cannot be castExplain Like I'm Five is the best forum and archive on the internet for layperson-friendly explanations. That being said, satellite phones to exist.I know they do exist, I was wondering why it wasn't a standard. Flagship phones cost over $1000 already being 5G capable perhaps we'll see Starlink ready devices for a little more.
