11. IEEE standards affect a wide range of industries
including:
⦿ power and energy
⦿ biomedical and healthcare
⦿ Information Technology
⦿ Telecommunications
⦿ Transportation
⦿ Nanotechnology etc

12. ⦿ IEEE is best known for
developing standards for the
computer and electronics
industry. In particular, the IEEE
802 standards for local-
area networks (LANs)
are widely followed.

13. networks and metropolitan area
network.
⦿ IEEE 802 splits the OSI Data Link
Layer into two sub-layers:
⚫ LLC(logical link control) sub layer
⚫ MAC(media access control) sub layer

15. IEEE 802.1 (networking) and Network Management
IEEE 802.2 Logical link control (upper part of data
link layer)
IEEE 802.3 Ethernet (CSMA/CD)
IEEE 802.4 Token bus (disbanded)
IEEE 802.5 Defines the MAC layer for a Token Ring
(inactive)
IEEE 802.6 Metropolitan Area Networks (disbanded)
IEEE 802.7 Broadband LAN using Coaxial Cable
(disbanded)
IEEE 802.8 Fiber Optic TAG (disbanded)
IEEE 802.9 Integrated Services LAN (disbanded)
IEEE 802.10 Interoperable LAN Security (disbanded)

16. IEEE 802.11 Wireless LAN & Mesh (Wi-Fi
certification)
IEEE 802.12 demand priority (disbanded)
IEEE 802.13 Not Used
IEEE 802.14 Cable modems (disbanded)
IEEE 802.15 Wireless PAN
IEEE 802.15.1 (Bluetooth certification)
IEEE 802.15.4 (ZigBee certification)
IEEE 802.16 Broadband Wireless Access (WiMAX
certification)
IEEE 802.17 Resilient packet ring
IEEE 802.18 Radio Regulatory TAG
IEEE 802.19 Coexistence TAG
IEEE 802.20 Mobile Broadband Wireless Access
IEEE 802.21 Media Independent Handoff
IEEE 802.22 Wireless Regional Area Network

17. It is concerned with:
⦿ 802 LAN/MAN architecture
⦿ internetworking among 802 LANs, MANs
and wide area networks
⦿ Interface between upper and lower layers
⦿ 802 overall network management

18. It defines Logical Link Control (LLC) as the upper
portion of the Data Link Layer.
The IEEE 802.2 sub layer adds some control
information to the message created by the upper
layer and passed to the LLC for transmission to
another node on the same data link.

19. ⦿ Defines the MAC layer for bus
networks that use CSMA/CD.
This is the basis of
the Ethernet standard.

20. ⦿ There are four cabling standards as per 802.3
1. 10Base5
2. 10Base2
3. 10Base-T
4. 10Base-F

22. ⦿ IEEE 802.4- Defines the MAC
layer for bus networks that
use a token-passing
mechanism (token bus
networks)
⦿IEEE802.5- Defines the MAC
layer for token- ring networks.

23. ⦿ 802.11 refers to a family of specifications
developed by the IEEE for wireless LAN
technology.
⦿802.11 specifies an over-the-air interface
between a wireless client and a base station
or between two wireless clients.
⦿ Wireless LANs primarily use CSMA/CA -
Carrier Sense Multiple Access/Collision
Avoidance.

24. There are several specifications in the
802.11 family:
⦿802.11- Applies to wireless LANs and provides 1 or 2
Mbps transmission in the 2.4 GHz band using either
frequency hopping spread spectrum (FHSS) or direct
sequence spread spectrum (DSSS).
⦿802.11a - An extension to 802.11 that applies to
wireless LANs and provides up to 54 Mbps in the 5GHz
band. 802.11a uses an orthogonal frequency division
multiplexing encoding scheme.

25. • ⦿802.11b - is an extension to 802.11 that
applies to wireless LANs and provides 11
Mbps transmission in the 2.4 GHz band.
802.11b uses only DSSS.
