   It is powered by the sun during the day, before switching to battery power during the night and can potentially stay airborne for 12 months. Featuring long-life battery technology, ultra-lightweight solar cells, a 35-metre (115 ft) wingspan and a weight of 150 kilograms (330 lb), the aircraft is designed to operate in the stratosphere .

4. List of WLAN channels - Wikipedia

   en.wikipedia.org/wiki/List_of_WLAN_channels

   Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.

5. DJI Phantom - Wikipedia

   en.wikipedia.org/wiki/DJI_Phantom

   It uses 2.4 GHz for control and is powered by a 2000mAh battery, giving it a flight time of about 15 minutes. [2] [3] [4] It did not include a built-in camera, but it can be fitted with an optional mount for a GoPro HERO camera. [4] The drone uses a GPS-enabled NAZA-M autopilot system allowing it to hover with automatic wind resistance. [2] [5]

6. List of battery sizes - Wikipedia

   en.wikipedia.org/wiki/List_of_battery_sizes

   The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. For example, a CR123 battery is always LiMnO 2 ('Lithium') chemistry, in addition to its unique size.

7. 2.4 GHz radio use - Wikipedia

   en.wikipedia.org/wiki/2.4_GHz_radio_use

   Certain car manufacturers use the 2.4 GHz frequency for their car alarm internal movement sensors. These devices transmit on 2.45 GHz (between channels 8 and 9) at a strength of 500 mW. Because of channel overlap, this will cause problems for channels 6 and 11, which are commonly used default channels for Wi-Fi connections.
