LTE has 20 MHz bandwidth divided into 100 resource blocks. Each resource block has 12 subcarriers and 7 symbols.

• LTE has 20 MHz bandwidth

• Divided into 100 resource blocks

• Each resource block has 12 subcarriers and 7 symbols

KPIs (Key Performance Indicators) of LTE include throughput, latency, coverage, and call setup success rate.

• Throughput measures the amount of data that can be transmitted over the network in a given time period.

• Latency measures the time it takes for data to travel from the source to the destination.

• Coverage measures the area where the network signal is available.

• Call setup success rate measures the percentage of succes...read more

CSFB stands for Circuit Switched Fallback, a technology that allows LTE devices to fallback to 2G or 3G networks for voice calls.

• CSFB is used when a LTE device is unable to make a voice call over the LTE network.

• It allows the device to switch to a 2G or 3G network for voice calls.

• CSFB is a temporary solution until VoLTE (Voice over LTE) becomes more widely available.

• CSFB can cause call setup delays and impact the user

OFDMA is used in LTE to improve spectral efficiency and support multiple users simultaneously.

• OFDMA allows for multiple users to share the same frequency band by dividing it into smaller subcarriers.

• It also enables dynamic allocation of subcarriers to users based on their bandwidth requirements.

• This results in better spectral efficiency and higher data rates.

• OFDMA is also resistant to interference and fading, making it...read more

FDD and TDD are two different duplexing techniques used in wireless communication.

• FDD stands for Frequency Division Duplexing and TDD stands for Time Division Duplexing.

• In FDD, separate frequency bands are used for uplink and downlink communication, while in TDD, the same frequency band is used for both uplink and downlink communication.

• FDD is used in technologies like 2G, 3G, and 4G LTE, while TDD is used in technolog...read more

Massive MIMO stands for Massive Multiple Input Multiple Output. It is a wireless communication technology that uses a large number of antennas at the base station to improve network performance.

• Massive MIMO uses a large number of antennas at the base station to improve network performance.

• It can significantly increase the capacity and coverage of wireless networks.

Handover is the process of transferring an ongoing call or data session from one cell to another.

• There are two types of handover: Hard Handover and Soft Handover.

• Hard Handover involves breaking the connection with the current cell before establishing a connection with the new cell.

• Soft Handover involves establishing a connection with the new cell before breaking the connection with the current cell.

• The handover process...read more

Pointers are variables that store memory addresses of other variables. They allow direct manipulation of memory.

• Pointers are declared using the * symbol.

• They can be used to pass values by reference.

• Pointers can be used to dynamically allocate memory.

• Example: int *ptr; ptr = # *ptr = 10;

• Example: void swap(int *a, int *b) { int temp = *a; *a = *b; *b = temp; }

Different types of pointers include null pointers, void pointers, function pointers, and array pointers.

• Null pointers: pointers that do not point to any memory location.

• Void pointers: pointers that can point to any data type.

• Function pointers: pointers that point to functions.

• Array pointers: pointers that point to the first element of an array.

Iterate through array using pointers

• Declare a pointer variable to point to the first element of the array

• Use a loop to iterate through the array by incrementing the pointer

• Stop the loop when the pointer reaches the end of the array

Min's angle from 5 to 5:40 is 120 degrees.

• The minute hand moves 360 degrees in 60 minutes.

• From 5 to 6, the minute hand moves 30 degrees per 5 minutes.

• From 5 to 5:40, the minute hand moves 30 degrees per 8 minutes.

• Therefore, the angle made by the minute hand is 30 degrees x 8 = 240 degrees.

• However, the angle between 5 and 5:40 is only 240 degrees - 120 degrees = 120 degrees.
