Narrow band vs Wide band
• 12.5 kHz or 25 kHz channels is narrow band in ETSI
• ETSI EN300-220 Categories for narrow bands
• Low RX filter bandwidth
– gives better sensitivity
– gives better noise immunity
– limits max data rate (9.6 kbps)
• Narrow band ACP requirements (adjacent channel Power)
RC17xxHP-RC232
Narrow band Frequencies
• 169 MHz Metering, Asset tracking, Social Alarm
• 500mW high power
• 433 MHz License free band (low power)
• 444 MHz Metering, specific bands in DK, NO, SE
• 500mW high power
• 458 MHz License free in UK, high power
• 865 MHz License free India, high power
• 868 MHz License free band (high power sub-band)
• RF module can be adapted to other frequencies
