 +  * http://​www.tuks.nl/​wiki/​index.php/​Main/​TelluricElectricWaves ​ - An alternative to using sattelites may be to use waves trough the interior of the Earth, Tesla style. 
 +  * http://​en.wikipedia.org/​wiki/​EME_%28communications%29 - Another alternative is to use a natural sattelite that is already there. Currently, an investigaton is being done to investigate the possibility of using longitudinal dielectric waves instead of the normally used transverse waves: http://​www.energeticforum.com/​renewable-energy/​9727-who-performs-first-longitudinal-moon-bounce-history.html ​ First result is that the prototype antenna that has been made does resonate at a frequency it is not supposed to resonate according to current accepted (transverse EM) wave theory: http://​www.energeticforum.com/​173559-post104.html
