er Wifi 802.11b en grei hastighet?

[Ola92]

Hei!

Jeg lurte på om Wifi 802.11b er raskt nok til å f.eks å åpne www.diskusjon.no eller tar det ca. 10 - 20 sekunder?

[Goliath]

b-standard innenfor wifi har en kapasitet på teoretisk 11Mb.

 

Wifi 802.11b har ingen innvirkning på hvor kjapt www.diskusjon.no kommer opp iom. dette er avhengig av bredbåndshastigheten din.

Hvilke standarder finnst egentlig?

 

Har bare sett G og B... finnst det flere?

Hvilke kommer i nær fremtid?

802.11

 

Definition: 802.11 is the generic name of a family of standards for wireless networking. The numbering system for 802.11 comes from the IEEE, who uses "802" for many networking standards like Ethernet (802.3).

 

802.11 standards define rules for communication on wireless local area networks (WLANs). Popular 802.11 standards include 802.11a, 802.11b and 802.11g.

 

802.11 was the original standard in this family, ratified in 1997. 802.11 defined WLANs that operate at 1-2 Mbps. This standard is obsolete today.

 

Each extension to the original 802.11 appends a unique letter to the name, as follows:

 

* 802.11a - 54 Mbps standard, 5 GHz signaling (ratified 1999)

* 802.11b - 11 Mbps standard, 2.4 GHz signaling (1999)

* 802.11c - operation of bridge connections (moved to 802.1)

* 802.11d - worldwide compliance with regulations for use of wireless signal spectrum

* 802.11e - Quality of Service (QoS) support (not yet ratified)

* 802.11f - protocol for communication between access points to support roaming clients

* 802.11g - 54 Mbps standard, 2.4 GHz signaling (2003)

* 802.11h - enhanced version of 802.11a to support European regulatory requirements

* 802.11i - security improvements for the 802.11 family (2004)

* 802.11j - enhancements to 5 GHz signaling to support Japan regulatory requirements

* 802.11k - WLAN system management (in progress)

* 802.11l - skipped to avoid confusion with 802.11i

* 802.11m - maintenance of 802.11 family documentation

* 802.11n - future 100+ Mbps standard (in progress)

 

Also Known As: 802.11X, Wi-Fi
