Why different rates of uplink and downlink?
It is because a mobile is operated on a battery with low power and therefore it sends signals on low(uplink) frequencies whereas a base station is driven by high power and can easily send signals on high(downlink) frequencies. This can be verified by Friis equation which says Transmitted power and Transmitted frequency are directly proportional.
What are the means through which data is transmitted and received?
Transmission Media
What is the port number for browsing?
General HTTP requests are transmitted and received on port 80. Secure data is transmitted on port 8080.
What are the maximum capabilities of an RF Cable?
An RF cable is an electrical connector designed to work at radio frequencies in the multi-megahertz range. Breakdown is a function of maximum voltage. Maximum capabilities is dependent on frequency since the typical value of VSWR is proportional to the increase in frequency.
The electrical data roadways through which bits are transmitted are called?
bus
Is data is transmitted in the form of digital or analog?
both but for analog usually a frequency Carrier is required
What is the maximum speed at which data can be transmitted between two nodes on a network.?
Data transfer rate (also called bandwidth)
How many maximum bits get corrupted if noise occurs for 1-on transmitted data at 48000 bps?
1
In AM transmission the frequency which is not transmitted is?
audio frequency
How many maximum bits get corrupted if noise occurs for 1-ms on transmitted data at 48000 bps?
1
What is binary data transmitted on?
Binary Data is transmitted on Data Buses.
Why high frequency carrier is required for a communication system?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver .
Factors that determine how data can be transmitted?
According to experts, a few factor s to determine how data can be transmitted is choosing the correct wire line media such as copper wire and radio frequency. In addition, cost factor and ease of installing and maintaining the cable line must be considered also.
Is digital signal frequency 0 Hz?
No, a digital signal does not have a specific frequency like an analog signal. Digital signals are represented by discrete values at specific time intervals and are typically transmitted using square waves with a fundamental frequency determined by the data rate.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
What is the frequency deviation for frequency modulation?
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
How do you use RF carrier waves to transmet large amounts of data?
RF carrier waves are modulated with the data to be transmitted, typically using techniques like amplitude modulation, frequency modulation, or phase modulation. These modulated signals are then transmitted through the RF channel. To transmit large amounts of data, techniques like increasing the carrier frequency bandwidth, using more advanced modulation schemes, and implementing error correction coding can be employed to achieve higher data transmission rates over the RF carrier waves.
