Why Wi-Fi in Embedded Systems?
 Use of available infrastructure and network planning
 Wi-Fi is largely present in most enterprise, industrial, and home
environments
 Access Point location and frequency planning already taken care
of
 Easy addition of devices
 Enterprise class security
 AES based WPA2
 Optional 802.1x based authentication
 Throughput and Range
 1 Mbps to 600 Mbps data rate
 Up to 500 meters range
 Power Consumption
 Focus on ‘low energy’ as opposed to ‘low power’
12
Why 802.11n?
 802.11n is lower power energy than 802.11b or 802.11b/g
 Minimal MAC overhead
 Higher PHY throughput
 Single-stream 802.11n is same cost at 802.11b
 Higher throughput at range
 Aggregation
 STBC
 Increases network capacity
 Mixed mode protection mechanisms waste bandwidth
 Wi-Fi infrastructure is increasingly 802.11n

The Network Advantage of 802.11n
 (Unnecessary) Protection Mechanisms take up plenty of air
time
 Just the presence of a 11g node in an 11n network reduces
overall network throughput by 30% or more

Questions
Question 1:
What functional procedure, developed by Joan Daemen and
Vincent Rijmen, was standardized by NIST after a 5-year
process involving 15 competing mechanisms, and is now a
core feature of the WPA2 certification from the Wi-Fi
Alliance?
Answer 1:
AES, or the Advanced Encryption Standard
Question 2:
Which standard in the 802.11 alphabet soup describes the
use of a modulation scheme based on Complementary
Codes, first introduced by Golay.
Answer 2:
802.11b (which describes CCK)
