Provided herein is a wireless communication system comprising a first device and a second device. The first device comprises a first radio type and a second radio type. The second device comprises a first radio type and a second radio type. The first device is adaptable to form a communication link with the second device using the first radio or the second radio. The first device can be adaptable to transmit data to the second device through the first radio type or the second radio type. The second device can be adaptable to form a communication link with the first device through dynamic switching between the first radio type and second radio type of the second device. The second device can be adaptable to receive data from the first device through the first radio type or the second radio type. The second device can be adaptable to transmit data to the first device using the first radio type or the second radio type. The second device can be adaptable to be in communication with the first device through dynamic switching between the first radio type and the second radio type and the second device can be adaptable to transmit data to the first device through the first radio type or the second radio type. Further provided herein is a wireless communication network comprising a plurality of devices comprising at least two devices, wherein at least two devices of the plurality of device are adaptable to form a communication link using a radio type selected from a plurality of radio types, wherein the network is adaptable to dynamically select the radio type used to form the communication link. The network can monitor the quality of the communication link between the at least two devices and is further adaptable to dynamically switch between the plurality of radio types in response to the quality of the communication link.
