Can my phone do that for the laptop? and here's a fun fact. I confirmed my tethering speed was 15kbps! And some dish nation employees told me there internet sucks and should get Comcast.
It depends on the phone, and I'm told in the US it may also depend on your plan (here in Canada it's always enabled if your phone supports it).
On my iPhone, I can tell it to create a wifi hotspot, and then I can connect anything that can connect to wifi to that hotspot, such as a laptop. The laptop then uses the iPhone as it's Internet connection. It's not fast at all, but it works almost anywhere.
but if it is possible to get fast internet for my phone(its the core of my tech life) and tether it to my laptop? I really am a mobile person(21 century rocks!). My laptop dose have one LAN port though I don't use it for internet that often in fear that a virus will corrupt my writing, I have MANY backups so IF LAN is good in your book it is in mine to. (viruses come from exotic sites alot... so its easy to use my replaceable phone and not my laptop .)
Since you have a 4G phone, it might be fairly fast. I know LTE up here is blazing fast. You'd need to call your phone provider and ask them what they can offer you. Then call Comcast and Verizon and see what they can offer you. Since you only need a basic package, you might find the wireline service reasonably priced.
I was under the impression (and it's the medias fault ) that LAN was slower because of the wires vs speed of light through the air?
It's not. Wireless has problems in that the equipment has to take the signal (which is originally electric and coming on a wire from the source, like a computer processor), convert it, broadcast it, convert it back on the other end, etc. All that adds latency, particularly the part where you broadcast it because only so many things can be broadcasting at once and if there's other people using the same thing, you'll have to wait your turn.
Electrical wires transfer slower, but they have a more dedicated path to where they're going, have simpler conversions, and so on. Plus they can be fiber optic, which means they're using light anyway. My home internet is actually a fiber line coming directly into my house, which gets converted inside. I can connect to that using Gigabit Ethernet (1000Mbps) or Wifi (~110Mbps, though in reality I rarely get that due to interference). The actual Internet connection is 80Mbps, but I could bump that to 170 with a 5 minute phone call and $15/month. It's so fast that I can buy and download a game from Steam faster than I can drive to the store, let alone buying it and driving back (and finding it in stock!).
The Ethernet LAN connection is ALWAYS faster because there is no interference and no multiple devices fighting over the ability to use the signal. It's also impractical in some cases, which is what makes Wifi so great.
