Is there a big speed diff between b and b+?

[someone16]

So I finally want to get wireless networking and was going to get these:
D-Link dl-614 b+ router
http://www.tigerdirect.ca/applicatio...=D700-2158%20P

D-link DWL-520+ b+ pci card OR
http://www.tigerdirect.ca/applicatio...p?EdpNo=329191

D-link DWL-520 b pci card.

Would b and b+ be a really big difference? the B+ pci is double the price of the b.

BTW, will the router be secure enough from anyone driving by and getting into the network?

One obvious difference is that the B+ card uses proprietary technology to double the standard 802.11b speeds. This only works if you use the D-Link B+ card for all wireless connections. I don't think the faster speeds would be reachable at further distances but I'm not sure.

This router appears to have the same security as most 802.11b WAPs plus an option for 256bit WEP key. So in general, if you take advantage of all the security options, it is reasonably secure for home use IMO.

802.11b+ uses Packet Binary Convolution Coding, a different modulation than standard CCK on regular 802.11b gear. It will double your throughput, or get close to it. If getting 8 or 9 Mb instead of 4 to 5 is worth the price, then go for it. You just have to understand you'll have to use b+ cards to get that added bandwidth. Frankly with the price of .11g stuff these days, anything else seems a bit strange. You can get .11g AP's, that use Texas Instrument chipsets, that will do 22 Mbps signalling using PBCC.

So about how much kb/s is 9mbps to 5 mbps?

approx. 4096 kilobits per second
