The Base Station Subsystem (BSS) (part of the 2G network) consists of 2 components; the Base Transceiver System (BTS) and the Base Station Controller (BSC). The role of the BSS is to take the wireless communications from the mobile station and convert it into a suitable state to be move on through the fixed line network; and the reverse
The BTS is the mast, which receives the data wirelessly from the mobile station and passes this, onto the the BSC. This is actually the only part of the mobile phone system that deals with the wireless communications.The wireless signals are decoded by the BTS and the data passed onto the controlling BSC
The frequency available is given to the mobile network operators is in 25MHz blocks. This is split into 124 carrier frequencies pf 200KHz; using frequency division multiple access. Each of the carrier waves is again split into 8 timeslots via Time Division Multiple Access. The data is modulated onto the carrier frequency using Gausian Minimum Shift Keying (GMSK). The 900MHz 2G frequency is split into an uplick (935-960MHz) and a downlink (890-915MHz).
The Base Station Controller will control one or more BTS within an area. It provides the intelligence behind the BSS. It manages the interface between the BTS and the MSC (Mobile Switching Centre). It has a significant role in the setup of a call and the management of the radio frequency. A major task in the management of the radio frequency is the management of the handover between cells when a mobile station moves from one location to another.
mobilephonetechnology.co.uk is a collection of terms used in mobile phone technology. The aim is to inform the user regarding mobile phone technology. It is our belief that users who have at least some understanding of the technology behind their phone can make informed choices regarding network use, device or app choice thus getting a better service from the phone and phone company.
An informed user can more confidently understand what is being said about the phone or network in the press or retail outlet and can make better decisions. The aim of this site is to provide some information about mobile phone technology to aid the informing of the mobile phone user
2016 was crossover year where over 50% of Internet traffic was driven by mobiles rather than laptops or desktops. The (smart)phone in your pocket is a very powerfull computer with fact connectivity.
The first mobile appeared in 1990 with the aim of providing mobile phone calls. Since then SMS messages were added as a secondary communication medium. The Internet was added in 2001 with the advent of WAP technology. Since then the phones and communications have developed to the modern ubiquitous smartphones of today.
Fast access to the Internet is key to the contemporary mobile phone user. It is needed to support many mobile apps, to deliver fast social media apps and information via the billions of Internet sites. What next? Your guess is as good as mine, but most observers believe that "artificial intelligence" will grow over the next few years.
