Yes, I have knowledge related to optic fiber.

• I have experience working with optic fiber cables in previous projects.

• I am familiar with the technology used in optic fiber communication.

• I understand the advantages of using optic fiber for high-speed data transmission.

MME helps in handover by ensuring seamless transfer of user context and session information.

• MME (Mobility Management Entity) ensures that the user's context and session information is transferred to the target eNodeB (Evolved Node B) during handover.

• This helps in maintaining the continuity of the user's ongoing session without any interruption.

• MME also coordinates with the source eNodeB to release the resources allocated to the user before the handover.

• This helps in efficient...read more

Copy constructor creates a new object by copying an existing object.

• Copy constructor is a special constructor that takes an object of the same class as a parameter.

• It creates a new object with the same values as the parameter object.

• It is used to initialize an object with another object's data.

• Example: class Person { public: Person(const Person& p) { name = p.name; age = p.age; } }

• Example: Person p1("John", 25); Person p2 = p1; // copy constructor called

LTE layers and QoS play a crucial role in managing large traffic.

• LTE has three main layers: the physical layer, the data link layer, and the network layer.

• QoS ensures that the network can handle the traffic demands of different applications and users.

• During large traffic, QoS prioritizes traffic based on its importance and allocates resources accordingly.

• For example, video streaming may be given higher priority than email traffic.

• LTE also uses techniques like carrier aggregat...read more
