What does “Two-way” satellite service mean ?
“Two-way” service means that data is both downloaded and uploaded via satellite. Some satellite systems, such as one-way systems download via satellite, but upload via your telephone line through a dial-up modem. This is a slower uploading process, and it ties up your phone line when you’re connected. Two-way service means faster and always-on connections and no busy signals and no related phone bills. 4.
