615 MHz Fully operational Making Telecoms Work LightSquared management and its investors are either on a roller-coaster ride of "ducking, diving, dodging and weaving," as those with South London entrepreneurial spirit might describe it, or they are following a master plan of great cunning and complexity. In case you've not been following, LightSquared is a US start-up, backed by a prominent investor fund, which has developed plans for the building of a US-wide wholesale 'hybrid' LTE network, using both conventional LTE deployment (base stations, femtos, etc.) and satellite- delivered LTE for those hard-to-get-at places.

But the 'Radio Network God' (whoever she is) is not easily placated by a slick presentation and few partner announcements. LightSquared ran into trouble over the interference problems it would allegedly visit on the Global Positioning System which operates in adjacent spectrum.

To bolster confidence, details were then leaked on a complex network sharing deal with Sp
