Each wireless transmitter possesses a range limit beyond which a wireless signal gets unable to receive. To overcome such issue, you can use wireless repeaters also known as wireless extension point. However, you can use more wireless access point for a large network, but it becomes messy to use such access points. It is a better choice to use wireless repeater instead. As you know, wireless networking signals are just radio signals. A wireless repeater receives all the radio signals at a frequency of 2.4 GHz (wireless communication frequency) and amplifies and then re-broadcast them. A wireless repeater provides connectivity between laptops or computers, which are at some distance.
