Last week, the group set aside the last of their differences, adopting a proposal put forth by the Enhanced Wireless Consortium, a interest group headed by Atheros, Broadcom and Intel. While it is not final just yet, chipmakers will likely begin to rush out chipsets compatible with the soon-to-be standard. However, the IEEE warns that until 802.11n is finalized, the products carry no guarantee of interoperability. Broadcom and Marvell have already announced chips based on the draft, with Broadcom saying its products would be upgradeable in case of any changes in the final revision. The first 802.11n chips could be released by the end of this quarter, Marvell said."</i><br /><br />Finally. I have been using 802.11 Pre-N for just over a year now and have been so happy with it. Connecting at just over 100Mbps wirelessly really makes life wonderful. I can video chat or VOIP chat over MSN very nicely and have had great flexibility with the added range. And 802.11n is going to be even better. According to tests, data rates of up to 600 MBps could be expected. 802.11n devices would also be backwards compatible with the earlier 802.11a, b and g specifications. And we had reported earlier how Intel is already geting chips with 802.11n built in, ready. So this is great news all round.

I am curious to the the real-life thoroughput you have observed in your pre-n setup.

I am curious to the the real-life thoroughput you have observed in your pre-n setup.
So I do actually reliably connect at 108Mbps. Though Jason, with the same setup that I have, has major problems connecting. So I am sure you will hear a lot of different kinds of experiences.

Regarding throughput, that is a hard question to answer. I have never done any formal benchmarks, however I have noticed that I have downloaded things (when the 802.11pre-n is connected to the web through the cable modem) at about 400KBps. With the same setup but using an 802.11b setup, I am limited to around 150+KBps. Same goes for transferring from one machine to another when one is a pre-n and the other is a b.

One word of caution, people buy 802.11pre-n routers but stick it out with the b card. I think that is a bad idea because you don't really experience any benefit (IMHO) and if anything it works worse because even though the two protocols are supposed to play nice, they don't. 802.11g is a different matter - I do successfully connect at around 54Mbps and can actually get about half the speed of the pre-n, which is nice.
