Abstract: A method and apparatus for a non-geosynchronous orbit (NGSO) satellite to comply with equivalent power flux density (EPFD) limits are disclosed. The example implementations may allow a constellation of NGSO satellites to comply with EPFD limits without disabling beams transmitted from the NGSO satellites. The power level of one or more beams to be transmitted from the NGSO satellites may be dynamically adjusted according to a beam power back-off schedule. In some aspects, the beam power back-off schedule may specify beam power back-off values as a function of latitude on Earth, and may allow for maximum allowable power levels for beams transmitted from the NGSO satellites without violating any of the EPFD percentile limits.

Abstract: A switch branch that improves voltage uniformity across a series stack of an n-number of transistors is disclosed. A first one of the n-number of transistors is coupled to an input terminal, and an nth one of the n-number of transistors is coupled to an output terminal, where n is a positive integer greater than one. Predetermined parasitic capacitances associated with each of the n-number of transistors are adjustable with respect to capacitance value by predetermined amounts by dimensioning and arranging at least one metal layer element in proximity to the series stack of the n-number of transistors. Capacitance values for the predetermined parasitic capacitances are selected such that a voltage across the series stack of the n-number of transistors is uniformly distributed. In this way, the n-number of transistors can be reduced without risking a transistor breakdown within the series stack of the n-number of transistors.

Abstract: User equipment (UE) is configured to automatically detect the presence of an access point (AP) in any one of a plurality of venues and to transmit identification information to the AP to authenticate the UE.
