Abstract: A computer implemented method for providing location based security controls on a plurality of user devices is provided. The method includes the following steps of: (a) defining a geo location of an area at a server, (b) defining a radius of said area where security policies are effective at the server, (c) retrieving a current location of one or more of users, (d) activating the security policies on the one or more users devices when the one or more users enter within the radius of the area, (e) restricting blacklisted applications and websites to be accessed on the one or more user devices, (f) accessing a camera of the one or more user devices to control the camera, (g) retrieving biometric information of the one or more users, and (h) tracking an attendance of the one or more users based on the biometric information of the one or more users.

Abstract: A method of transmitting a data bit stream on a multi-carrier transmission system is provided. The steps include estimating a signal to noise ratio for each carrier for a known transmit power for each carrier, allocating a quantity of bits for each carrier within limits imposed by a target bit error rate and the estimated signal to noise ratio, computing a total excess power available for a current allocation of bits, computing additional power that would be required by each carrier to carry additional bits, and allocating the total excess power based on the computation of additional power required by each carrier to carry additional bits. The computation of additional power needed may be performed by computing the additional gain necessary to carry additional bits or by computing the additional excess power necessary to carry additional bits.
