[Wireless] 300 vs. 450 Mbps

Hi,

Started shopping for a simultaneous dual-band router and had some questions:

1) 450 Mbps (eg. Linksys E4200) and three-stream N is the same thing correct? And this requires a "special" NIC right?

2) Would the typical 5 GHz N mobile device (eg. Windows tablet or laptop) support speeds that high (without buying a new NIC) or is everything pretty much 300 Mbps or below still?

->g.

1 .. 3 stream N does not necessarily equate to 450 Mbps so no its not the same thing. In the E4200 specific case it does equate to 450 Mbps.

2 .. The typical 5 Ghtz mobile device will not support speeds higher than the built-in NIC is capable of supporting. To support 450 Mbps the mobile devices must have NIC's capable of communicating at the higher speeds and bandwidth.

1) So what does 3 stream mean then in general and to the E4200?

2) So I guess what I was asking here is what does today's typical laptop or Win tablet support...300? Less? Are manufacturers of mobile devices keeping up with 802.11N or should I just get the E3000 instead?

2 .. for the typical Laptop made today you need to check the technical specifications for that laptop to find out the speeds etc. The same goes for Tablets. For Tablets Apple make a point of being current or leading edge --- for Windows the high end units will be current or leading edge; the more economical models are lagging -- which is why it is very important to check the technical specification for the product being considered.

1 .. 3 streams typically means that there are 3 radios and 3 antennas working concurrently to send/receive data. From a technical perspective the radios and antennas are controlled by software built into a chip that can determine how-to work based on information being received from the client NIC. If the Client NIC only works on 2 streams then that spacial software dumbs down the 3 streams to 2 streams.

The E3000 would be the one I would suggest that you consider in view of the fact that no-one has yet released any client that I am aware off that can support the higher speeds of the E4200.

The Intel Centrino Ultimate-N 6300, Intel 533AN_MMWW2 supports and the TRENDnet TEW-687GA IEEE 802.11b/g/n Ethernet Port Wireless Gaming Adapter support 450 Mbps

actually you would need 6 antennae 3 for 2.4 and 3 for 5 and all have to be in sync to be able to achieve the theoretical 200mbps on each band...

Generally you need to have a specific wireless card to access the 450Mbps speeds. Like the Intel WiFi Link 5300 or Intel Centrino Advanced-N 6300 Wireless Card and 6200 Wireless Card. Both support 802.11a/b/g/n

I change out my wireless card in my Sony laptop with the Intel Centrino Advanced -N 6200 and receiving 300Mbps through out my home.
