Draft n and g bands

[retired123]

HI
Just read a post on extending the distance on a wifi setup and was wondering.
There are routers that are draft-N and downward compatible to wireless G. As I understand things the draft n transmit power is higher.
If you have a router that is draft N and a laptop that is G then the signal goes over the G band. Is the power output for the G band as high as it would be on the N band?

Also, is the receiving sensitivity on the draft N router higher thus able to receive a weaker signal?

There is No difference in the Output Power between Draft_N and 802.11g.

Draft_N extra bandwitdh suppose to be achieved by the MIMO type concoction of the Antennae, the Power into the Antennae is the same about 33-40mW in the Entry Level Router.

All Draft_N suppose to be compatible with 802.11g

Power output should be the same. Signal is different though depending on if it's 5ghz pre-N or 2.4ghz pre-N. 2.4ghz is supposed to be compatible with G/B while 5ghz will only be compatible with A. 5ghz doesn't travel as far and has more difficulty going through objects than 2.4ghz but 5ghz has fewer issues with interference.

There is Draft_N that is only 5GHz?

Draft N frequency depends on the specific band of the radio. Some are only 2.4ghz, some are 5ghz and others are dual band (you can select either 2.4ghz or 5ghz) and simultaneous dual band (dual radios that put out both 2.4ghz and 5ghz frequencies at the same time). I've seen various brands and models that are mixtures of the above. I surely hope at some point the N is actually standardized as it's looking promising. In my experience, the Pre N access points work the best, the Pre-N routers I've seen work pretty much like crap. But I have to careful of what I say because there's a certain person on here that apparently goes off the handle when someone says anything that he doesn't agree with but anyway. But I have actually worked with lots of customers that are definitely buying all of this Pre-N stuff so I've seen a lot of different models. The most common one I've seen is just the 2.4ghz followed by dual band 2.4ghz/5ghz where you can select between which frequency you want the radio to broadcast. But again, the ones that actually seem to work ok are just the access points. I haven't seen many Pre-N routers that actually work ok. Not sure if it's an incompatibility between the clients but just a lot of issues.

The good thing I have seen is that with the Draft N that is 5ghz, if the client also has either Draft N or 802.11A, they can also use the 5ghz 802.11A in it and it performs well because it avoids all the noise in the 2.4ghz area. I'm still holding off actually recommending Draft N until it's standardized, whether the guy on this forum believes it or not, it's still beta until it's actually standardized, which hopefully won't be much longer.
