商品簡介
商品簡介
The Earth is soon to be cross-hatched by over 300 million cellular and personal communications services (PCS) telephones. From 1991 when they were introduced to now, time division multiple access (TDMA) digital phones and services have escalated more than 60 percent annually. The text uses some 100 illustrations to explain IS-136 and IS-54 TDMA technology, services, and unique features. Following an introduction to industry terminology, chapters demystify: analog cellular systems, IS-136 and IS-54 systems, mobile phone design options, cellular networks, testing requirements, supportive data services, multimode/ multiband phones, and marketing factors. Appends TDMA system standards, the countries using AMPS and IS-136 TDMA, control channel selection and camping criteria, and a description of reselection.
