I'm looking for any kind of wireless service that allows you to access the internet wherever you are in your city, similar to a cell phone, without the need to rely on hotspots. It can be dial-up or broadband. Do such services exist? If so, what are some?
the 3G network does this. You get a little usb thingy and plug it in and it connects via the 3G cell network, like a mobile phone. Three bad things I noticed: 1) speed is slow, not much better than a dial-up 2) the usb device is a bitch to install 3) support is only available by registering at the 3G site and giving them all your details.
Cellular wireless broadband does not rely on hot spots. Reading between your vague requirements, it would seem that cellular broadband or perhaps email only services would work. Whatcha gonna be doing?
Yes, such services exist. WiMax is the most common type.
Did you check if your cellular provider has an IM only service? Verizon Wireless does:
If messaging is your forte, you might look into 2-way paging, Blackberry/RIM, Terrestar/Motient, etc.
How "full" do you want? You don't need "full" internet access just to run a chat room.
The defunct Metricom/Ricochet network would have done the job at
19.2Kbit/sec, but that's gone. Some cellular providers still have low speed (about 14.4Kbits/sec) access. As I recall, Verizon was charging me an extra $5/month. However, data connect time counted against my monthly minutes, whether data is moving or if I'm just reading the screen. That added up fast so I dumped the service.
Suit yourself. Try here:
The TowerStream, Clearwire, and Sprint sites all have WiMax coverage locators. For other WiMax providers, slog through this list:
Also search Google for "WISP WiMax".
Also, if you have a suitable vehicle on which to mount a rather large (1 meter) dish, you can possibly subscribe to one of the satellite internet vendors. Hughesnet and WildBlue are the major players.
well, without knowing the city, i'd say plan on spending BIG BIG BIG bucks for a two way satellite internet system, they work on RV's all over... course if you would part with a bit of information, you may get some cheaper alternatives... oh well, Close mouth and open wallet....... :)
Use your mobile phone (what the yanks call cellular) as a modem. Its going to be expensive. (in Europe) You'd be looking at 3G data services or maybe EDGE. Many if not all major mobile phone companies have a data package. You can access these from anywhere you can get phone reception.
The alternative, if you're lucky, is a citwide wireless network of some sort. See
if your chosen city has a muni wireless broadband network you'd know - they're expensive to install, rare and tend to be heavily advertised in a desperate attempt to recoup costs.
