12. 12 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’

13. 13 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

14. 14 Mixed Network 11n Network 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

15. 15 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)
