802.11n?

IEEE 802.11n?

Can someone here enlighten me in a user friendly way, what is exactly IEEE 802.11n :?:

Thanks!

range of wifi??

Alien words symbol :slight_smile:

wi-fi rating. now i think is 802.11g? something like that la…

802.11n should be…wimax?

This is a new wifi technology that is more powerful than 802.11g. 802.11n data tranfer rate is several time faster than 802.11g. The range is also grater. Miri is going to be wifi city but i don’t think they will upgrade to this one.

Wikipedia will tell u all…click on the link below…

Check Check!!

no worries… i m in the same shoes as u too… after reading it… still doesn’t have a full clue of that the hack is that… :roll:

Maybe we can DEMAND from BN or maybe DAP to give us 802.11n! See they dare to promise or not… hahahaaa… Since BN said Miri WAS already new… so, we’ll see how new Miri can be…

  • The 802.11g specification is a standard for wireless local area networks (WLANs) that offers transmission over relatively short distances at up to 54 megabits per second (Mbps), compared with the 11 Mbps theoretical maximum with the earlier 802.11b standard.
    Networks employing 802.11g operate at radio frequencies between 2.400 GHz and 2.4835 GHz, the same band as 802.11b. But the 802.11g specification employs orthogonal frequency division multiplexing (OFDM), the modulation scheme used in 802.11a, to obtain higher data speed. Computers or terminals set up for 802.11g can fall back to speeds of 11 Mbps. This feature makes 802.11b and 802.11g devices compatible within a single network. Modification of an 802.11b access point to 802.11g compliance usually involves only a firmware upgrade.

The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications (bold in table below) include 802.3 Ethernet, 802.11 Wi-Fi, 802.15 Bluetooth/ZigBee, and 802.16.
The following table lists highlights of the most popular sections of IEEE 802 and has links for additional information:

802 Overview Basics of physical and logical networking concepts.
802.1 Bridging LAN/MAN bridging and management. Covers management and the lower sub-layers of OSI Layer 2, including MAC-based bridging (Media Access Control), virtual LANs and port-based access control.
802.2 Logical Link Commonly referred to as the LLC or Logical Link Control specification. The LLC is the top sub-layer in the data-link layer, OSI Layer 2. Interfaces with the network Layer 3.
802.3 Ethernet “Grandaddy” of the 802 specifications. Provides asynchronous networking using “carrier sense, multiple access with collision detect” (CSMA/CD) over coax, twisted-pair copper, and fiber media. Current speeds range from 10 Mbps to 10 Gbps. Click for a list of the “hot” 802.3 technologies.
802.4 Token Bus Disbanded
802.5 Token Ring The original token-passing standard for twisted-pair, shielded copper cables. Supports copper and fiber cabling from 4 Mbps to 100 Mbps. Often called “IBM Token-Ring.”
802.6 Distributed queue dual bus (DQDB) “Superseded **Revision of 802.1D-1990 edition (ISO/IEC 10038). 802.1D incorporates P802.1p and P802.12e. It also incorporates and supersedes published standards 802.1j and 802.6k. Superseded by 802.1D-2004.” (See IEEE status page.)
802.7 Broadband LAN Practices Withdrawn Standard. Withdrawn Date: Feb 07, 2003. No longer endorsed by the IEEE. (See IEEE status page.)
802.8 Fiber Optic Practices Withdrawn PAR. Standards project no longer endorsed by the IEEE. (See IEEE status page.)
802.9 Integrated Services LAN Withdrawn PAR. Standards project no longer endorsed by the IEEE. (See IEEE status page.)

802.11 Wi-Fi Wireless LAN Media Access Control and Physical Layer specification. 802.11a,b,g,etc. are amendments to the original 802.11 standard. Products that implement 802.11 standards must pass tests and are referred to as “Wi-Fi certified.”
802.11a Specifies a PHY that operates in the 5 GHz U-NII band in the US - initially 5.15-5.35 AND 5.725-5.85 - since expanded to additional frequencies

Products that implement 802.16 standards can undergo WiMAX certification testing.

no shadow ley :lol: :lol: :lol:

its basically a faster wireless standard than 802.11g… we’re still using ‘g’ now and ‘n’ is still in trial before it is finalized (will be finalized dis year i think). i think we have to wait a few more years b4 ‘n’ is finally supported here in miri … so don worry.
