11. PHY-SAP Data Throughput
March 2003
PHY-SAP Data Throughput
Data throughput are adjusted by two parameters
bits/symbol: 1bit/symbol, 2 bits/symbol, 3 bits/symbol
No. of channels: 2 or higher
Lowest data rate are supported by 1bit/symbol + single-band transmission
Highest data rate are supported by 3bits/symbol + multi-band transmission

12. Coexistence with narrowband interferer
March 2003
Coexistence with narrowband interferer
IEEE a is the strongest narrowband interferer
Coexistence mode
Do not use band #3 for GHz
Do not use band #4 for GHz WLAN interferers
Channel allocation can be dynamically assigned depending on channel monitoring results

Regulatory Impact
Geopolitical scope
Multi-band usage pattern can be dynamically configured depending on location of usage
Do-Hoon Kwon, Samsung Electronics Co.,Ltd.(SAIT)

15. Scalability Data rates Frequencies of operation Power consumption
March 2003
Scalability
Data rates
110Mbps is supported by two-band transmission
Higher data rates are supported by multi-band parallel transmission and higher bits/symbol
Lower data rates are supported by single-band transmission and 1bit/symbol mode
Frequencies of operation
As the UWB frequency band expands, more sub-bands can be defined
Power consumption
For low data rates, single-band mode operation reduces power consumption
