In GSM (Global System for Mobile Communications), BCC stands for “Base Station Color Code.” The Base Station Color Code is a parameter used to differentiate and identify neighboring cells or base stations in a GSM network. BCC helps mobile devices and the network to distinguish between adjacent cells that use the same frequencies, preventing interference … Read more
In GSM (Global System for Mobile Communications), BCCH and TCH are two types of logical channels used for communication between the mobile device and the base station. These channels play distinct roles in the GSM network, serving different purposes in the exchange of control and traffic information. BCCH (Broadcast Control Channel): Purpose: BCCH is a … Read more
ILEC, or Incumbent Local Exchange Carrier, refers to a telecommunications company that originally provided local telephone services in a specific geographic area before the entry of competitive local exchange carriers (CLECs). The term “ILEC” is often used in the context of telecommunications regulation and competition. Key Characteristics of ILEC: Incumbent Position: ILECs were historically the … Read more
Antenna receiver diversity is a technique used in wireless communication systems to improve the reliability and quality of signal reception by employing multiple antennas at the receiver. The primary goal of antenna receiver diversity is to mitigate the effects of fading, signal attenuation, and other propagation challenges in radio frequency (RF) environments. This technique enhances … Read more
