Ericsson Interview Questions, Process, and Tips

Types of antennas include dipole, Yagi, parabolic, patch, and helical antennas.

• Dipole antenna: simple and commonly used for radio and TV broadcasting

• Yagi antenna: directional antenna with multiple elements for increased gain

• Parabolic antenna: dish-shaped antenna used for satellite communication

• Patch antenna: flat, compact antenna often used in wireless communication

• Helical antenna: spiral-shaped antenna used for circul

There are two main versions of IP addresses: IPv4 and IPv6.

• IPv4 addresses are 32-bit numerical addresses, expressed in four octets separated by periods (e.g. 192.168.1.1).

• IPv6 addresses are 128-bit hexadecimal addresses, expressed in eight groups of four hexadecimal digits separated by colons (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

NR Technology stands for New Radio Technology, which is the global standard for a unified, more capable 5G wireless air interface.

• NR Technology is the foundation of 5G wireless communication systems.

• It provides higher data rates, lower latency, and increased reliability compared to previous generations.

• NR Technology operates in both sub-6 GHz and mmWave frequency bands.

• It enables new use cases such as IoT, smart cities

A coupler is a device used to split or combine RF signals, while a tapper is used to attenuate a portion of the signal.

• Coupler splits or combines RF signals, while tapper attenuates a portion of the signal

• Coupler has multiple ports for signal input/output, tapper typically has one input and two outputs

• Coupler has a fixed coupling ratio, tapper allows for adjustable attenuation levels
