|Marine HF are several frequencies that usually operate in [[Single side band]] ([[SSB]]) mode.  They operate around 4MHz and enable ships at sea to communicate globally both in voice and with data.

|a data protocol primarily for connecting [[computer]]s, [[mobile device]]s like [[smartphone]]s and [[tablet computer|tablets]], [[PDA]]s and other [[network]]ed devices together [[wireless]]ly.  Some devices have a considerable range, and adding a quality [[antenna]] to these can extend their range, although usually at the expense of making them cover a smaller geographic area.  This is a good general purpose multi-user high speed data link.  Range can be anywhere from a few feet to a few miles based on a wide variety of factors.

|designed to be a [[cable]] replacement.  There are 3 different levels of [[Bluetooth]] devices, some of which go up to 100m range.  If a quality antenna is added range can be extended further.  Since Bluetooth is designed to replace cables, it is only intended to have a limited number of devices connect concurrently.  At most with a piconet you can have 7 devices connected.  This can be a method to exchange data in close proximity, such as maps, frequency plans, or other data.
