Embodiments of the present disclosure provide systems and methods for secure Short Message Service communications. If the data is clustered data, the method, program product and the service first obtains the clustered data from its source. The first group G11 has, in order from the object side, at least one concave lens and at least one convex lens. Also, data of the second data stream are assigned to the signal points of each signal point group. This information may be determined prior to deploying the clock downhole. A method for framing data, the method includes storing data and metadata required for framing the stored data at one or more memory devices.
