A method implemented in a computer infrastructure includes: determining a current location of a mobile communication device; determining a route of a user associated with the mobile communication device; and determining mobile call rates for the user at locations along the route. The antenna apparatus comprises a plurality of substantially coplanar modified dipoles. The locations of the traffic congestion zones are then determined based on the locations of the low-power access points that identified high demand. Based on the reception operation information, the base station transmits a reception operation indication to the terminal. As for such an electrocatalyst, carbon monoxide does not fundamentally come in contact with the activated metal adsorbed to the inner surface of the pores of the support body, thereby minimizing degradation of fuel cell performance, thus overcoming fuel-feeding problems. Also, if imprinting of one particular logical state is induced in advance, then the read accuracy further improves.
