Mabye a walkie-talkie or radio. I am not sure.
In iOS, there are different modes such as normal mode, recovery mode, and DFU (Device Firmware Update) mode. Normal mode is the standard mode for device operation. Recovery mode is used for restoring or updating iOS on a device that cannot boot up. DFU mode allows for the installation of a custom firmware or troubleshooting more complex issues.
Some common modes of transportation into space include rockets and space shuttles. Rockets use powerful engines to propel spacecraft beyond Earth's atmosphere, while space shuttles are reusable spacecraft that launch like a rocket and land like an airplane. Both of these vehicles are used to carry astronauts and cargo into space for missions to the International Space Station or beyond.
Well Airborne RADAR works in similar manner as their Ground counterpart , the differences typically lies in mode of operations, processing software , physical size and functions .usually Airborne RADAR's , especially for those who's required to detect target that flies at low altitude uses Doppler measurements to differentiate between target and steady objects like grounds . It's also may have a "compensations" to correct tracking error caused by the carrier's own movement EDIT- It seems the previous answer is bit too complex for some people Air to Air airborne radar uses combinations of range ambiguous and Doppler ambiguous modes. High Pulse Repletion Frequency (HPRF) modes which are range ambiguous, to measure Doppler unambiguously. Low Pulse Repletion Frequency (LPRF)modes measure range unambiguously both of these modes still measure both Range and Doppler and resolve the ambiguous measurement using Chinese remainder theorem. This resolving of the ambiguous measurement uses different measurement parameters that are not related provide a measurement remaining that can be related to unfold Range or Doppler measurements. In between the HPRF and LPRF is the Medium Pulse Repetition Frequency Mode which are both Range and Doppler ambiguous. Repetition Rate of Pulses adaptation can be mixed together and sequenced. Some modes are have better properties then others for measuring particular targets or characteristic of some targets. The question of ambiguity, and therefore what defines a Pulse Repetition Frequency as High Medium or Low is dependent on the target characteristic and the range you wish to measure to.
Scott and his team used a combination of ships and sledges pulled by ponies and dogs to reach the South Pole during the Terra Nova Expedition in 1911-1912. They primarily relied on using ponies and dogs for overland travel across the icy terrain of Antarctica.
Limitations of blimps, dirigibles, and hot air balloons include their susceptibility to weather conditions, limited speed and maneuverability, and dependence on wind patterns for navigation. They also have low payload capacities and are typically more expensive to operate compared to other modes of transportation.
Two astronauts sitting in the same space ship can communicate by mouth ... at least while it's full of air ... or by passing notes. As soon as they put on their space suits, though, or if they feel like talking to anyone on earth or in another spaceship, radio is the only way. However, they could revert back to "archaic" technologies like sign language or perish the thought semaphore.

Mass communication is a way for a population to communicate and relay information to a large number of people at once. Some modes include: television, Internet, telephones, and the radio.
