This paper presents the wireless network architecture to provide multilingual speech translation and local positioning system during Hajj operations. The pilgrims require low power, low cost and compact ear connected devices to receive the information in their native language. The proposed RF transceiver front-end design consists of multiple numbers of oscillators tuned within spectrum of 5-to-8.5 GHz. In transmitting mode, oscillators are periodically turned on and off for short period of time to generate UWB impulses. In receiving mode, oscillators are operated in super-regenerative configuration to detect multi-channel narrowband OOK modulated data bits.
