Um... Mbps means 'millions of bits per second', and is a measure of data transfer rate. Looking around, I notice that 54 Mbps is the claimed maximum throughput rate for your typical wireless network connection. Expect less than half that rate in the real world. I see 15 Mbps typically - with the wireless router within 10 feet and in a clear line of sight to the interface card. Kind of misleading, don't you think?

Note that a little 'b' implies bits and a big 'B' implies Bytes, which contain 8 bits. So, to start with, you get one-eighth the throughput the marketing types know you are thinking of. What a difference a B makes! A bit is a single "on' or 'off' in the binary language of computers.

When vendors play games with specifications, they like us to get confused on certain items. You'll see this word-play in data rates with 'bit' versus 'byte', and in storage capacity when they divide total hard drive capacity in bytes by 1,000 rather than the correct 1,024. At least the latter is a smaller "stretch" of the truth than the 8-to-1 difference between bits and bytes. Hard drive formating overhead - and the available space that removes - is hardly ever mentioned. Reminds me of gas pricing, with the nine-tenths-of-a-cent syndrome.

Powers of two are the language of computers. This means measurements are by 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, etc., because of the way computers natively compute and allocate memory.

Mbps or Mb/s means megabits per second. Do not confuse internal LAN speed with internet speed. Wired LAN speeds have been 100 Mbps for some time and in the past 5 years or so 1000 Mbps or 1 Gb speeds have been introduced. This is the speed on the LAN. Internet speed is a different story. Download speed of ADSL seems to max around 3 Mbps and CATV (cable tv internet) is often 6 to 10 Mbps. CATV talks about and does in some cases deliver 20 to 50 Mbps. If you are in fact seeing 1.56 Mbps down and 0.66 Mbps up it is moderate to slow DSL. Do not confuse 1 MBps with 1 Mbps. There are 8 b per B. In fact if your internet speed was 8 Mbps it is also 1 MBps (8 : 1 ratio). Finally there is NO way you upgraded your Internet speed to 100 GBps or 800 Gbps. In fact there is NO way you upgraded your LAN to 800 Gbps either.

IT'S BITS, NOT BYTES!!! Thank God for "widowmate"!

It means the data that's being transmitted is coming and going at 54 megabits per second. The small b makes it bits, a big B would be bytes, and is a very common mistake, until you try to fix or program something. Bits to bytes need math (while souldly based on the magic number 1024, think 100 bits = 12.5 bytes) to break down. For instance a fast ethernet is 100 Kbps (Kilobits per second), thats 100,000,000 bits (1's and 0's) per second, but translates to 12,500,00 bytes per second. An average (old) modem of 56.6 Kbps would translate to 7200 bytes per second. It helps to know the numbers when you're trying to calcuate file transfer times. I think the industry goes with bits on its speeds over bytes to make it sound sexy and because they know many don't know the difference. To just say 'megs' would leave me hangin'. Sorry for the long answer, but the bit and bytes confusioin is a pet peeve of mine.

I am sure ur using a wireless g router or a modem which works on 54(Mbps) Mega bytes per second........

U can go for linksys router(model no WRT300N) which gives u 300(Mbps) Mega bytes per second and the range wud be 280-300 feets which is the best..........
