Phone as hotspot or portable router with SIM card

[ozmeldo]

Would it be possible to have 40 people accessing the school internet using a phone as a hotspot? Each would have very minimal usage, but it would be constant over an hour.

 

A WiFi router using a Sim 

wouldwork. Anyone know where I could find one on Amazon for use in Thailand or at Fortune?

 

With only my user/pw no admin access would it be possible to set up an old Linksys router as a repeater on a school network? How might I play with that?

 

Thank you

MiFi/phone 'hotspots' have a limit of ten connections, so instead you would need something like this instead; http://www.totalaircard.com/categories/3G-Router/4G-Router-แบบใส่-SIM/

One way to do it is, as you wrote, is with a WiFi router as a repeater logged into your phone (hotspot) or personal WiFi device.  This would get you past the 5-8 connected client limit.

 

The only main issue with wireless repeaters or extenders is they tend to use the same WiFi channel, cutting your effective available wireless speed in half, as half the time it's connected to your phone/hotspot and the other half connected to client devices.

 

I try to get around these type of issues by using dual-band WiFi routers and use 5GHz to connect to the phone and 2.4GHz for client connections ...but if you're going to that extent then, as the previous poster suggested, you might as well get a SIM-based 3G/4G/LTE WiFi hotspot router.

Using the phone as a hotspot for an hour can cause overheating issue. Your best option is to get a 4g/LTE router like Huawei.
