2. Introduction
A base transceiver station or cell site (BTS) is a piece of equipment that facilitates
wireless communication between user equipment (UE) and a network. UEs are devices
like mobile phones (handsets), WLL phones, computers with wireless internet
connectivity, Wi-Fi and WiMAX gadgets etc. The network can be that of any of the
wireless communication technologies like GSM, CDMA, WLL, WAN, Wi-Fi, WiMAX etc.
BTS is also referred to as the radio base station (RBS), node B (in 3G Networks) or,
simply, the base station (BS). For discussion of the LTE standard the abbreviation eNB
for enhanced node B is widely used. So, to understand BTS we have to go through the
basics of GSM system because BTS is a part of a GSM system. The Base Transceiver
Station (BTS) is a network element maintaining the Air interface. It takes care of Air
interface signaling, Air interface ciphering and speech processing. In this context,
speech processing refers to all the functions the BTS performs in order to guarantee an
error-free connection between the MS and the BTS. The Transcoder (TC) is a BSS
element taking care of speech transcoding, i.e. it is capable of converting speech from
one digital coding format to another and vice versa. The BTS, BSC and TC together form
the Base Station Subsystem (BSS) which is a part of the GSM network taking care of the
following major functions.
Cellular communications systems have become integral to the modern world, enabling
businesses to interact with customers, clients and colleagues in unprecedented ways.
They have also helped to shape society and culture, with trends formed by SMS
messages and now social networking via mobile phones enabling information, comment
and news to be shared more easily than ever before. There are number of different
systems that deserve attention and here we will examine the major standards. Cellular
phone is one of the fastest growing and most demanding telecommunications
applications. For this both GSM and CDMA technologies are widely used in all over the
world. Global System for Mobile Communication (GSM) is perhaps the best-known
cellular communications standard in the world. This is the case because it has become
the most popular format used by network providers on a global scale. 3G refers to the
third generation of cellular communications technology to emerge and it is part of a
family of wireless standards. Nowadays 3G mobile has also been deployed in most

3. countries. In this situation, in our country yet GSM technology is prominent. During this
internship extensive work have been done on GP SWAP under the sub-contractor
company, Ring Tech (BD) Ltd, installation of all equipment’s of GSM technology at
GRAMEEN PHONE Limited (GP) Project. In this internship at first site survey and radio
planning have been made. Then BTS installations have been made by Huawei
equipment. After all of these installments the integrity of the whole system has been
tested. By all these processes the efficiency of the GSM network has been extended.
