If you are using residential broadband, such as cable or DSL, you will need a modem suitable to that technology. Cable modems are available from most computer stores or can be rented from your cable company. If you choose to purchase your own modem, make sure it is compatible with the service and speed you are subscribing to. DSL modems are normally provided by your telephone company. For mobile broadband, you can either use your existing phone and set it up as a Wi-Fi hotspot to allow other devices to share the Internet connection (provided your phone is hotspot capable and your data plan permits it), or you can purchase a mobile hotspot device directly from your provider. For other personal services or dedicated business broadband solutions, such as T1 and T3 lines, check with your Internet Service Provider for specific requirements.
