Internet of Things (IoT) has grown rapidlly in various sectors including health sector. There are many technologies used for IoT such as Wi-Fi, Bluetooth, and LTE-Advanced. IoT for health sector in Indonesia is used to improve health services based on telemedicine services roadmap by Indonesian Ministry of Health. This services include teleECG, teleRadiology and teleUSG which utilize mobile technology. In Indonesia, there is a tendency that IoT will be implemented on a large scale. Meanwhile, Indonesia is expected to experience deficiency of 500 MHz mobile spectrum in 2020. Therefore, the calculation of spectrum for telemedicine services is urgently needed. This paper aims to calculate the spectrum that is required for health sector in Indonesia by using mobile technology especially LTE. We use the method of general LTE planning equation. The result is the requirements of spectrum for telemedicine services will be growing 14.44% until 2025. On 2025, telemedicine services are predicted to use 165,47 kHz. Regardless of the spectrum needed by telemedicine services is only in the order of kHz, it should be considered since it will enlarge spectrum deficiency in Indonesia. The government of Indonesia should prepare about strategic spectrum management to anticipate the massive growing of IoT application, such as a roadmap of IoT development and a regulation of specific frequency in the nearest future.
