# The relationship between bandwidth and transmission rates of hiv

it decreases the rate of data generation/ transmission to the network to avoid congestion and throughput will be decreased, as seen in figure 12 and packet loss ratio The dynamic spectral aids algorithm stands for cooperation and in this. Whatever the contribution to overall HIV prevalence at population levels, the Year Lowess smoothed curve with bandwidth Fig. Keywords: hearing aids, bandwidth, gain, time constants, automatic gain .. Indigo bit sound card, using a sampling rate of kHz, and presented via The measure of bandwidth preference was taken as the difference between the .

Say I have a channel that can only pass signals whose frequency is between f1 and f2. Its frequency response function the channel's reaction to signals of different frequencies might be something like this: The bandwidth of a channel depends on the physical properties of the channel, so a copper wire will have a different bandwidth from a wireless channel and from an optical fiber.

Herefor example, is a table from wikipedia, specifying the bandwidths of different twisted pair cables. If our example channel has a bandwidth of 1Mhz, then we can fairly easily use it to send a signal whose bandwidth is 1Mhz or less. Signals with a wider bandwidth will be distorted when passing through, possibly making them unintelligible.

### Nyquist formula: relating data rate and bandwidth

If we were to perform a Fourier analysis on it, we would discover that increasing the data rate by making the bits shorter and closer to each otherincreases the signal's bandwidth. The increase would be linear, so a two fold increase in the rate of bits, will mean a two fold increase in the bandwidth.

The exact relation between bit rate and bandwidth depends on the data being sent as well as the modulation used such as NRZQAMManchseterand others. The classic way in which people draw bits: Since the exact bandwidth of a binary signal depends on several factors, its useful to look at the theoretical upper bound for any data signal over a given channel.

We expect to see that there are two ways to increase the speed of data transmission: Results When we send 5 megabytes 40 Mbits of data at a rate of 0. However, if we change the bitrate to 2 Mbps, 2 MHz of bandwidth is used and the transmission takes about 20 seconds.

To reduce the speed of data transfer by a factor of 4, we had to increase the bandwidth by a factor of 4: Finally, on changing the constellation size to 4 points squaring the number of signal levels relative to the first transmissionthe transmission also takes about 20 seconds, but uses only 1 MHz, when transmitting at 2 Mbps: You will have to make your reservation in advance. To reserve WITest, visit http: Then, use the reservation calendar to reserve one or two consecutive hours for this experiment.

For further information, refer to this tutorial on the reservation system. Then, click on "Control Panel". Use the calendar interface to request time on sb2, sb3 or sb7.

Set up testbed At your reserved time, open a terminal and log in to the console of the testbed that you have reserved. This is usually your regular GENI username with a geni- prefix, e.

From the testbed console, run: If you are using WITest note that there is no space around the comma: This process can take minutes. Don't interrupt it in middle - you'll just have to start again, and it will only take longer.

If it's been successful, then once the process finishes running completely you should see output similar to: Then, turn on your nodes with the following command: Prepare your receiver Open a new terminal window, and run the following command to tunnel the ShinySDR ports between your laptop and the receiver node: If you are using WITest note: Then, in that terminal window which should now be logged in to your testbed consolelog on to the receiver node: If you are using WITest: Configure your Shiny window as follows: Click on the "hamburger" icon in the top left corner to open the menu, if it isn't already open.
