Initial installation may be more expensive with satellite service than initial installation with cable TV. Satellite dishes can be costly, so if your plan doesn’t include a satellite dish and installation, you can end up paying a good deal extra for these services. However, a lot of companies will include a satellite dish and installation for no extra cost, so just be sure to read the fine print.
Cable ISPs leverage some of the bandwidth they use to bring people television service to deliver data - thankfully without any noticeable negative impact to the former, in most cases. Cable is an always-on connection, which means that your modem is always in communication with your ISP, and it tends to be faster than DSL because your distance from the service provider isn't an issue. The only drawback of cable internet is that service delivery is sometimes less reliable during peak usage hours, as cable customers local to one another share their bandwidth.
