Abstract

The European cellular environment is described, and the types of cellular environments that are able to support lightweight handheld portables are addressed. Microcellular structures are considered, covering propagation measurements, rapid handover, interfacing with local area networks, and highway microcells with an overlaying macrocell. Narrowband transmission of subband-coded speech by 16-level QAM and high-bit-rate transmission are discussed. Picocells, i.e., very small areas or volumes that might encompass an office, a house and its immediate environment, or a hot spot that provides high-capacity communication, are considered.<>
