External effects on performance
Require line of site?	no	yes	no (Clear uses NLOS capable equipment)
Distance from base station	3 Kms from exchange	n/a	upto 15kms from base station - but able to extend to 50 Kms
Interference prone?	no	Satellite performance is susceptible to weather - e.g heavy rain/snow/hail	no - Clear wireless has interference immunity protection in its design And we operate on a frequency that has very few devices
Weather affected?	no	yes (see above)	no
Security	none	requires satellite equipment but basic security only	Military Standard; including BRAID, and DES encryption
