There is provided a system and method for providing group calling in a wireless network. The discretely variable capacitance may provide coarse tuning adjustment of the variable capacitance to compensate for capacitor and inductor tolerances and to adjust the output frequency to be near the desired frequency output. Specifically, the first lenslet array has motion sufficient to reduce speckle by averaging multiple speckle patterns across its array. Based on a traversal of the path-compressed binary trie, an index is created comprising a first array of internal nodes encountered during the traversal, and a second array of leaf nodes encountered during the traversal. A side-chain crystallizable polymer such as poly, that is solid below the base temperature and is a viscous liquid above the activation temperature can be employed.
