1 TV has signal and mobile phone has no Internet
2 TV receives signal through antenna or cable TV, while mobile phone is connected to the Internet through wireless network, so mobile phone can not receive signal without network.
3 The TV signal is sent through the TV station or cable provider, and the mobile phone needs to be connected to the carrier's network to receive the Internet signal, so the mobile phone can not receive the signal without the network.
4 In addition, the transmission distance of TV signals is relatively long, and the wireless network signal transmission distance of mobile phones is relatively short, so the mobile phone can not receive the signal in the area without network coverage.
5 Therefore, television has a signal and mobile phones do not have an Internet because they receive and transmit signals differently.
Television and mobile phones transmit signals in different ways. TV signals are transmitted by radio waves, while mobile phones are transmitted by wireless networks. TV signals can be received through antennas, while mobile phones need to be connected to the Internet. In addition, the coverage of TV signals is greater than that of cell phone signals, because TV signals can be transmitted farther through broadcast towers, while cell phone signals need the support of base stations. Therefore, even if there is no cell phone signal in some areas, you may receive a TV signal.
