The endoscopic capsule needs a bidirectional data transmission for its operation. The downlink from the capsule to the outside world must be able to transmit a large amount of data. The available data rate will define the image quality of the endoscope. However, to get a high data rate one needs to increase the radio frequency of the carrier wave of the signal; but the higher the frequency, the higher the absorption of the waves by the human body. As the available power for the transmission is limited, a dedicated transmitter will be needed. The definition of the protocol is also part of the radio transmission since it will affect the Bit Error Rate of the system.
The uplink, from outside the body to the capsule, does not need a high data rate since the only commands are transmitted through this link. However it needs to be highly secured to avoid any unexpected comportment of the capsule while traveling through the human body. Therefore the protocol must be extremely robust in order to let the physician rely on it.
