Band Plan• Bandwidth : Two bands
- Low band (3.1 to 4.9 GHz) : Mandatory band
- High band (5.825 to 10.6 GHz)
Low band
3 4 5 6 7 8 9 10 11
High band

Low Band Pulse Design : Example (1)• Prolate pulse*
• More multipath Immunity than (M-ary) BPPM & BPSK!!
• No additional complexity to mitigate IBI!!

Location Awareness : Scenarios
• Criteria
– Mobility of Nodes- Stationary, movable, or mobile
– Density of Nodes- Dense or sparse
– Mobility of Reference Nodes- Stationary, movable, or mobile
– Position Accuracy- Low / Medium / High accuracy
