Add your answer
Q2. How will you get the tilt in the base station antenna?
Ans. 
The tilt in the base station antenna can be adjusted by physically changing the angle of the antenna.
• Tilt can be adjusted by loosening the bolts on the antenna mount and manually changing the angle of the antenna

• Specialized tools like tilt meters can be used to ensure the correct angle is achieved

• Remote electrical tilt (RET) systems can also be used to adjust the tilt of the antenna electronically

Q1. What is HO? and its type? Events in HO
Ans. 
HO stands for Handover. It is a process of transferring an ongoing call or data session from one cell to another.
• There are two types of HO: Intra-cell HO and Inter-cell HO

• Intra-cell HO occurs when a mobile device moves from one channel to another within the same cell

• Inter-cell HO occurs when a mobile device moves from one cell to another

• Events in HO include HO Request, HO Access, HO Required, HO Command, and HO Complet

Q2. Whats is MCR ?How we can improve MCR? What is the reason of MCR?
Ans. 
MCR stands for Maximum Cell Rate. It is the maximum rate at which cells can be transmitted through a network.
• MCR is an important parameter in ATM (Asynchronous Transfer Mode) networks.

• It is used to ensure that the network does not become congested.

• MCR is determined by the network operator and is based on the capacity of the network.

• Improving MCR can be done by increasing the capacity of the network or by optimizing the...read more

Q4. Whats is Volte call flow?
Ans. 
Volte call flow is the process of establishing and maintaining a voice call over a 4G LTE network.
• The call is initiated by the user and sent to the LTE network

• The network sends a SIP invite message to the called party

• The called party responds with a SIP 180 ringing message

• Once the call is answered, the network sends a SIP 200 OK message

• The voice call is established and maintained over the LTE network

Q5. Whats is difference between cell throughput and user throughput?
Ans. 
Cell throughput refers to the amount of data transmitted by a cell, while user throughput is the amount of data received by a user.
• Cell throughput is the total amount of data transmitted by a cell, including data sent to all users within the cell.

• User throughput is the amount of data received by a single user within the cell.

• Cell throughput is affected by factors such as the number of users, signal strength, and availa...read more
