DRS zones on the Sepang International Circuit in 2011. 1: DRS detection point. 2: DRS activation point. 3: approximate DRS deactivation point (braking zone before Turn 1) Use of DRS is restricted by the F1 rules; it is permitted only when both: The following car is within one second of the car to be overtaken, which may be a car being lapped.
Can be freely used in practice and qualifying, but in the race only when within 1 second of the next car by the detection zone, and only activated in the activation zone. DRS wing must immediately close under braking, and DRS is de-activated in the first 2 laps of each race, plus when a track is declared wet. 107% qualifying rule re-introduced ...

The idea is to directly use software ECCs in the communications. For instance in the 5G, the software ECCs could be located in the cloud and the antennas connected to this computing resources: improving this way the flexibility of the communication network and eventually increasing the energy efficiency of the system.
Carrier-sense multiple access with collision detection CSMA/CD is used to improve CSMA performance by terminating transmission as soon as a collision is detected, thus shortening the time required before a retry can be attempted. CSMA/CD is used by Ethernet. Carrier-sense multiple access with collision avoidance
Error-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, [11] [12] as well as for reliable storage in media such as flash memory, hard disk and RAM. [13] Error-correcting codes are usually distinguished between convolutional codes and block codes:
