2010 Honda Accord Adds New Features on Select Models

Upgrades include expanded application of Bluetooth and available new rear seat vents

Available as a sedan or a coupe, the Accord is designed to impress with a quality feel, engaging performance and accommodating technology.

The 2010 Honda Accord lineup receives new features on certain models with an expanded application of Bluetooth® HandsFreeLink® to vehicles equipped with leather seating surfaces (previously exclusive to navigation-equipped models) and new rear seat ventilation ducts on Accord Sedan EX and EX-L models for more-direct rear passenger airflow. Subtle modifications include graphically optimized climate control buttons and the addition of a trunk roof lining on Accord EX models.
'The Honda Accord offers something for a diverse range of people seeking anything from a comfortable family car to an aggressive coupe with looks and power,' said Erik Berkman, vice president of American Honda Motor Co., Inc. 'The feature changes to the 2010 Honda Accord elevates its appeal and supports a legendary reputation as a class leader for quality and customer satisfaction.'
The Accord Sedan's exterior expresses an upscale and powerful presence with a distinctive 6-sided grille, flared fenders and inset character lines sculpted into the sides of the body. Building on the sedan's design character, the Accord Coupe's unique muscular stance is highlighted by a longer hood, projector beam headlights and a sleek, lower-profile roofline.

What is GSM Technology?

What is GSM Technology?

Global System for Mobile Communications (GSM)



GSM network is designed by using digital wireless technology. It offers compatible wireless services to all mobile users in all over the world. The basic requirements for GSM are following:

* Services
* Quality of services and security
* Radio frequency utilization
* Network

Services: The services, which are provided by the system, should be potable to all Mobile Stations or Mobile Phones so that it can b used in all over the world.

Quality of services and security: The quality of both voice and data services of GSM should be good. The voice data is encoded in digital form by using a modulation technique i.e.Gussian Minimum Shift Keying (GMSK).The security features should be provided by the system to protect the network against unauthorized users.

Radio frequency utilization: The system should use the available band of frequencies (For uplink: 890-915MHz & For downlink: 935-960MHz) efficiently.

Network: Network designers manage the identification and numbering plans while switching and mobility management based upon signaling system i.e. Signaling System Number 7(SS7).
GSM Architecture

The main component groups of GSM architecture are:

* Mobile Stations (MSs)
* Base Station System (BSS)
* Network and Switching Subsystem (NSS)

Mobile Stations (MSs):

The Mobile Station (MS) consist of two operational parts.

1. Mobile Equipment (ME)
2. Subscriber Identity Module (SIM)

Mobile Equipment (ME): This is the hard ware used by the subscriber to access the network and it has a unique identity number known as International Mobile Equipment Identity (IMEI).

Subscriber Identity Module (SIM): This is a type of electronic card that is plugs into ME and contains detailed information about the mobile subscriber.

Base Station System (BSS):

BSS is central equipment, which is located at the cell site. It provides the link between MS and NSS. The BSS consists of two operational parts.

Base Transceiver Station (BTS): BTS consists of transmitting and receiving antennas and signaling equipment that provide air interface for a cell to route the call. BTS communicates with the MS.A single BTS can support one or more cells.

Base Station Controller (BSC): All switching functions, which are performed in MSC, are controlled by BSC. It also supports handoff strategies and allocate or release temporary channels for those users whose needed handoff. Several BTSs can be controlled by a single BSC and one MSC can serve many BSCs

Network Switching Subsystem (NSS)

It is the main switching center of GSM network. NSS includes the following:

Mobile Switching Center (MSC): It is the basic unit of NSS, which supports call-switching or routing functions. Its purpose is the same as that of telephone exchange but due to advanced wireless technology, its working is much better than that of exchange. Each MSC provides coverage to a defined geographic area only.

Home Location Register (HLR): For subscriber its a reference data base. Current location of MS, identification numbers and various addresses are maintained in it.

Visitor Location Register (VLR): It’s also a type of database. When an MS moves from home location to a visited location then its location is registered as a visitor in the VLR of visited system and this information is also updated in HLR of MS, by the VLR.

Equipment Identity Register (EIR): Its again a type of database, which contains information about MS equipment and check and identify its international validity of hardware and software to work properly.

Authentication center (AUC): Its a processing center and is normally worked together with HLR.Like HLR its also require to continuously access or update subscribers data. Its main purpose is to provide data security features to authenticate the subscriber.
