Could someone please explain how this hotspot feature usually works for smartphones? I'm having a discussion with a friend about this, but we're going nowhere since I don't own a smartphone and thus I'm not really sure what's the default here and how this iPhone does things differently.
[edit] what I expect is this: if I'm connected to a wifi hotspot to browse the Internet and I receive a telephone call, I should not drop the connection to the hotspot (am I wrong in understanding that this is NOT what this iPhone does?).
- brown9-2 16y ago"You can use it as a WiFi Hotspot" means that you can use the phone to broadcast a WiFi signal for nearby computers/devices to use to access the Internet. The phone acts as a WiFi access point, using the cellular network to relay the devices connected to it to the Internet.
- mziulu 16y agoYeah, this is ok, but how does this iPhone behave differently than the usual here? Do the other phones (when acting as hotspot) keep broadcasting the WiFi signal when receiving data over the cellular network?
- InclinedPlane 16y agoThis is basically what is called "tethering", using the 3G internet connection of the phone for other devices (such as your laptop), except that the "tether" is no a physical connection but just a wifi connection. In other words, you put your phone into this mode and you can connect to it through wifi and have wireless internet anywhere you have 3G coverage. AT&T does not offer the same service.
- orangecat 16y agoAT&T does not offer the same service. Of course, it's worth noting that tethering isn't a "service" that carriers have to build or support. It's an inherent capability of a sufficiently advanced computing device that has access to two networks simultaneously. But in a textbook case of non-neutrality, AT&T (and others) prevent you from using that capability unless you pay them to remove the entirely artificial restriction.
- InclinedPlane 16y agoQuite so. AT&T restricts your ability to tether, because there are still unlimited data plans and they don't want people to fully take advantage of those plans.
- jonknee 16y agoIt's a limitation to CDMA, so if the same feature were allowed by AT&T you wouldn't have a service interruption due to voice usage (GSM can do voice and data simultaneously).
- pak 16y agoWell, you can demonstrate this already either with normal Bluetooth tethering or with MyWi after jailbreaking.
- stanleydrew 16y agoThe hotspot feature turns the phone into a wireless router where the connection to the internet is provided through the phone's data connection. I don't think an incoming phone call would cause the wifi network to disassociate from any devices, but connected devices wouldn't be able to access the internet. This would be akin to disconnecting your modem from your home wireless router. Devices can still access the network but can't reach the internet.
- treyp 16y agodoes this apply to SMS too? if the phone gets an incoming text, will it disconnect the internet?
- kurtsiegfried 16y agoNo, SMS is different, you can receive a text during a phone call, or during a data session.
