Scalable Polyphony MIDI
• Software MIDI synthesizer to maximise flexibility• Playback with the whole range of phones• SP MIDI compatible with standard MIDI – interoperability through
using same files in different devices• Compact format – requires less than 10 times less space than MP3
• 3GPP SP-MIDI profile defines the device requirements for polyphony levels up to 24
Playback example 2: Techno.mid• 4 simultaneous notes• 8 simultaneous notes• 14 simultaneous notes
All samples were recorded at sampling rate Fs = 16 kHz

AMR Wideband Speech Codec
• New 3GPP codec extends audio bandwidth from 3.4 to 7 kHz and offers superior voice quality for 3G mobile systems
• Chosen also by ITU-T: the first time the same codechas been adopted for both wireless and wirelineservices
• Jointly developed by Nokiaand VoiceAge

Complementing Cellular
• WLAN is an important indoor tehnology in the overall radio technology picture
• Key WLAN standards on unlicensed & shared, ”non protected” bands:
• IEEE 802.11b: 11Mbit/s @ 2.4Ghz, and IEEE 802.11a: 54Mbit/s @ 5 GHz
• ”Uncoordinated deployment”, e.g. not guaranteed roaming or throughput everywhere/outdoors (private, ISM bands, …)
• 3GPP is specifying the UMTS/WLAN interworking (Target: R6 / '03)
• Bluetooth offers high data rates in near environment:• Specification radio channel data rate:
1 Mbps, throughput maximum: 700 kbps,connection setup time varies now between 0-2.5 s
