A dual-purpose bridge for wireless communication allows both a low frequency wireless communication standard and a high frequency wireless communication standard to operate for a particular wireless communications device. The interface processors and peripherals together form a network processor capable of cooperating with other elements including an optional switching fabric device in executing instructions directing the flow of data in a network. The method can also include applying a first conformal circuitry layer on the first conformal dielectric layer. The invention also relates to methods of preparing such compounds and to intermediates useful in such preparation. The inventive cellulose fine particles have an average particle diameter of 9 to 400 nm and an average polymerization degree of cellulose of 150 to 3,000. The formation of hydrates may be monitored with consistent and reproducible results.
