Paper Abstract

The link budget determines the relationships between range, capacity and transmitted power for any wireless technology. In every case it is a key determinant of the system's performance from both an engineering and an economic point of view. Unfortunately, the new 1.9 GHz PCS systems will begin life with an inherent 7 dB disadvantage over the 800 MHz cellular due to propagation differences. Additionally, system wiring and electronics often degrade performance by a further 5 to 10 dB due to long coaxial runs and noisy front end amplification, both of which are harder issues to deal with at 1.9 GHz than at 800 MHz. SCT's REACHTM products address these shortcomings by packaging critical components--front end amplification, filtering, etc.--in a compact cryoelectronic package intended for mounting near the antennas of the base station. In a recent trial with Qualcomm in San Diego, this package improved the CDMA uplink budget by 6 dB--enough to halve the number of base stations that are needed in most areas. This paper examines the technical and economic ramifications of the REACHTM product.
