1. A system comprising: a plurality of parachutes, each parachute being of a type which, when dropped from a height, exhibits a non-guided free-fall flight path, each parachute comprising a frame made from a metallic material and a covering attached to the frame; a payload, the payload comprising a wireless communications circuit electrically connected to the frame to use the frame as a first antenna;wherein the wireless communications circuit of each of the parachutes' payloads is configured at least to: detect at least one neighboring wireless communications circuit; andestablish a reception and transmission channel with the neighboring wireless communications circuit via at least the first antenna, thereby forming an ad-hoc wireless communications network; andwherein one of the plurality of parachutes further comprises a first external link thereby providing an exit point from the ad-hoc wireless network; or a second external link thereby providing an entry point to the ad-hoc wireless network. 2. The system according to claim 1, wherein the frame comprises a plurality of spokes each comprising a first end and a second end, the spokes being attached together towards their first end, the second ends of the spokes each being so attached to a flotation device as to engender buoyancy to the system. 3. The system according to claim 2, wherein the first antenna further comprises an antenna extension describing a horizontal plane located towards the first ends of the spokes, the first antenna thereby being configured as a discone antenna. 4. The system according to claim 1, further comprising a second antenna electrically connected to the payload, the wireless communications circuit being further configured such that it additionally communicates via the second antenna, the second antenna being connected to the wireless communications circuit such that the second antenna adopts a vertical attitude with respect to the ground at least when the system is on the ground. 5. The system according to claim 1, further comprising a cushion for providing protection to the payload upon landing, the cushion being attached to the payload in such a way that the cushion lands before the payload. 6. The system according to claim 1, wherein the covering comprises a solar panel for charging a battery for supplying the wireless communications circuit. 7. A wireless mesh communications network comprising a plurality of systems according to claim 1, wherein the wireless communications circuit of each system is configured to detect a presence of at least one neighboring wireless communications circuit and to establish at least one reception path for receiving at least part of a first signal and to establish at least one transmission path for transmitting a second signal towards another neighboring wireless communications circuit. 8. The wireless mesh communications network according to claim 7, wherein at least one of the systems further comprises a first external link for providing an exit point from the network. 9. The wireless mesh communications network according to claim 7, wherein at least one of the systems further comprises a second external link for providing an entry point to the network. 10. A non-guided free-fall retarding device for deploying a wireless communications circuit, the non-guided free-fall retarding device comprising: a payload including a wireless communication circuit;a frame; anda covering attached to the frame;wherein the non-guided free-fall retarding device is configured as a parachute, and wherein the frame is made from a metallic material and is configured to be connected to the wireless communications circuit, the frame serving as an antenna for the wireless communications circuit;wherein the non-guided free-fall retarding device is configured to detect neighboring wireless communications systems and to build communication channels between neighboring wireless communications systems, thereby forming an ad-hoc wireless communications network; andwherein the non-guided free-fall retarding device is further configured to establish a first external link, thereby providing an exit point from the ad-hoc wireless network, or a second external link thereby providing an entry point to the ad-hoc wireless network. 11. The non-guided free-fall retarding device according to claim 10, wherein the frame comprises a plurality of spokes interconnected towards a first end, each of the spokes having a flotation device attached to a second end. 12. The non-guided free-fall retarding device according to claim 10, wherein the covering comprises a solar cell for charging a battery. 13. The device according to claim 10, wherein the antenna comprises a plurality of spokes each having a first end and a second end and an antenna extension describing a horizontal plane located towards the first ends of the spokes, the antenna thereby being configured as a discone antenna. 14. A method for establishing a wireless mesh communications network over an area, the method comprising: dropping a plurality of parachute systems above an area, each parachute system being of a type which exhibits a non-guided free-fall flight path, each parachute system comprising a frame made from a metallic material and a covering attached to the frame, each parachute system having: a payload, the payload comprising a wireless communications circuit electrically connected to the frame to use the frame as a first antenna;configuring the plurality of parachute systems to detect neighboring parachute systems and to build communication channels between neighboring parachute systems, thereby forming a wireless ad-hoc communications network;wherein one of the parachute systems further comprises a first external link thereby providing an exit point from the network; or a second external link thereby providing an entry point to the network. 15. The method according to claim 14, wherein one of the parachute systems further comprises a first external link thereby providing an exit point from the network; and a second external link thereby providing an entry point to the network.
