Atheros无线网卡芯片全介绍
Atheros may now be the world's largest supplier of wireless card chip, and it's probably Csico. Atheros in the field of wireless card chip, with Intel in the field of central processing is quite similar, is in China's Taiwan island enterprises. Although Intel's CPU and chipset are those, the motherboard looks different and different from each other. Same, although Atheros chip group just a few generations, but the wireless network card that manufacturer produces is somewhat different however. It's really a little confusing. In fact, whether it's Netgear or D-Link, IBM or Toshiba, many of its wireless cards are Atheros chips.
---------------------------
Approximate chronology of Atheros products
2006, launched 5008 series, launched 802.11n draft 1 standard a/b/g/n card, global wireless chip up to 50 million
2005, launched 5006 series, launched the global integration of the most concentrated single chip g frequency card; Atheros single chip PCI-E wireless network card was born, the world provides 20 million wireless chips, and issued smart antenna system.
2004, launched 5004 and 5005 series, launched the world's first single-chip g frequency wireless routing; Atheros single chip a/b/g full frequency network card, single-chip U disk
A/b/g wireless network card
2003 launches the 5002 series
2002, the introduction of 5001X a/b/g full frequency network card, and won a Las Vegas exhibition Grand Prize Award
2001, the introduction of 5000, for the a frequency single frequency card
2000 begin production of a frequency wireless network card
1998 Atheros was funded by the Stanford University, the Berkeley, California, and some private sector experts (in Taiwan).
--------------------------------------
Here is a brief introduction of the Atheros wireless network card several generations chipset. In fact, 5212a chips are more of a distinction between Atheros chips and 5213a chips. In fact, this distinction is not very strict. The real Atheros chip naming method is named after the algebra + letters of the chip. Atheros has roughly 7 generations from 5001 to 5008. I don't know why there is no 50035007 and only one AP. And we are exposed to more than 5002, 5004, 5006. The main difference between its generations is the improvement in chip count and power consumption, but only by 5008 did the 802.11n leap.
----------------------------
AR5001
Since it is the first generation of Atheros products, the chipset has the largest number of chips and 3 chips. Contains three products:
AR5001X+
For the a/b/g chipset tri band 54M, composed of three chips, respectively, AR 2111, AR5111 and AR5212. The working voltage is 2.5-3.3V, and there are three kinds of products: PCI, minipci and PC card.
AR5001A
For the a frequency card, containing AR5111 and AR5211 two chips, the same PCI, minipci and PC card three products
AR5001AP
A frequency is the wireless routing, combination chip for
AR5111 and AR5311.
AR5002
As the second generation of products, but also let the Atheros start to open and gradually occupy the market of the chip, the number of a/b/g three card chip was reduced to 2, by 5212a and 5112 (or 2112).
At present, Taobao sells most of the wireless network card chip for more than 5002 generations of products, that is, commonly
known as 5212a. The group chip related products include
AR5002AP-2X, AR5002AP-G, AR5002AP-X, three AP models and
AR5002G/AR5002X two network card models, the network card also includes pci/minipci/pc card three product forms.
AR5002X
There are 5212a and 5112 two chips, of which 5112 are included in the shielding cover sheet, is the b/g frequency processing chip; 5212a support a/g, should be to deal with superAG function chip. This chip supports 54M a/b/g three, while supporting super AG to 108M. Many notebook manufacturers have used this chip, such as IBM's first generation 54M a/b/g wireless card, that is, FRU 91P7418 that section.
AR5002G
Composed of AR2112 AR5212, the b/g dual band 54M-108M card.
AR5002AP-2X
Includes three chips, AR2112, AR5112, AR5312, a/b/g, AP.
AR5004
This is the current mainstream 5213a chipset, and now the mainstream notebook, many are using this group of chips. By 5004, the chip had improved on power consumption and heating. 5002 of the chip in the card body on both sides of the distribution, 5004 instead of a single distribution, so that the motherboard near the surface of the heating greatly reduced. The chipset
mainly consists of two groups of AR5004G and AR5004X, b/g card and a/b/g card respectively. This batch of card finger different manufacturers is different, with a 5002 pin, a few needles, such as the two generation of IBM a/b/g card, the finger foot a few less than 5002 times. See the pictures in the second posts.
AR5004X
Chips are AR5112 and 5213, and they are the largest group besides the 5212 chip. Is also now circulated on the Internet, can successfully crack 01C9 reported the highest chip group. In more than 5004 of the Atheros cards, the current hack program is poorly supported because 5005 and 5006 of the EEPROM have write protection. This has been confirmed on special internet. The minimum operating voltage of the 5213 chip has been reduced to 1.8V. Is a typical representative of the two generation of 93P4262 IBM a/b/g.
AR5004G
The chip is made up of AR2112 and AR5213, and it is b/g card. Others are the same as 5004x.
AR5005
This chip is mainly applied to pci-E, U disk and PC card products, make Atheros products covers more and more competitive chip. At the same time, part of the chip is a single chip.
AR5005G and AR5005GS
The chip is monolithic AR2413 (the former) or 2414 (the latter), allowing the original b/g card to be reduced from dual chips to single chips. Relatively more power saving, operating voltage 1.8-3.3V. Only minipci and PC card models.
AR5005UG and AR5005UX
This is the 5005 version of the two generation of U disk version. Among them, UX is AR5112, AR5523 chip a/b/g full frequency, UG is AR2112 AR5523 chip b/g card.
AR5005VA and AR5005VL
Enhanced version has 3 chips, 1 AR5513, 2 AR5112, 5513 of which makes the video wireless receiving function has the support of HDTV (I don't know how to work, receive DVD player signals?). Where VA is PCI card or USB boxed card, and VL is PC card.。
