The two most popular mobile communication standards by market penetration are the GSM and the CDMA based systems. In many developing countries, over 80% of the populace use the GSM technology while the CDMA technology is left with a dwindling share of less than 20%.Inspite of the huge investment in infrastructure by the GSM operators, the networks are still faced with poor service quality and a high rate of dropped calls due to insufficient bandwidth to cater for the increasing number of subscribers. This paper presents two network architectures that will enable the bundling of both the GSM and CDMA spectrums to maximize spectrum efficiency and also minimize the rate of dropped calls. This architecture will not require special licensing of the operators and operators can utilize their existing infrastructure with very minimal changes required for the GSM operators. The architectures have the potential of improving spectrum utilization and improving overall user experience by utilizing the CDMA infrastructure to transmit the excess GSM voice traffic. The two architectures presented in this work are both designed to be implemented by the installation of specially designed Transceiver cards in the BTS which will enable GSM operators utilize either the spectrum of the CDMA operators or both the spectrum and infrastructure of the CDMA operators to transmit the excess calls on their network. These architectures will enable the GSM operators retain their customers and their infrastructure while enabling the CDMA operators earn some revenue from their idle infrastructure and spectrum while the users will continue to use their mobile sets without having to change them.
