DSL Broadband tips

What is Broadband?

Broadband is another communication technique in which large amount of data for example audio and video, is transmitted over long distances simultaneously. In broadband transmission, FDM (Frequency Division Multiplexing) technique is used, in which multiple signals can be transmitted simultaneously. Broadband is the bandwidth used for direct communication between very high speed in mainframe computer. This bandwidth includes satellites, fiber optics media.

What is DSL Broadband?

DSL Broadband basically a high bandwidth internet connection that can transmit and download large amounts of date or information with high speed. You can transmit data 10 times faster than a dial-up connection. We can transmit data in broadband with 512 Kbps to 10 Mbps speed and more. There are many broadband Internet connection providers are available for users but the main competitor of DSL broadband is the cable internet broadband. If the both services are available in your area then always go for DSL broadband due to its reliability and dedicated internet connection as compare to cable broadband.

Advantages and Disadvantages of DSL Broadband Internet Connection

DSL Broadband Internet data transmission speed start from 128 Kbps up to 10 Mbps.
DSL is dedicated connection not shared with other internet user.
DSL monthly rates are between 50$ to 100$.
Your internet speed will depends upon the distance between your home to DSL provider.
Advantages and Disadvantages of Cable Broadband Internet Connection

Cable Broadband Internet Connection data transmission speed is start from 64 Kbps to 30Mbps.
Cable internet is not a dedicated connection but shared with other internet user.
Cable monthly rates are between 30$ to 60$.
No distance matter with Cable connection between your home to Cable provider.

General Packet Radio Service (GPRS)

GPRS protocol is a packet-switch protocol; define for web applications in GSM network. In other words Internet on GSM network is standardized as GPRS network. GPRS has digital structure and this structure based on Time Division Multiple Access (TDMA) technique. One TDMA frame has 8 time slots (TSs). These TSs can be allocated to users, and single TS can be shared by several active users for uplink and downlink purposes. Different coding schemes are used to enhance data rate from 9Kbps to 150 Kbps per user, and it takes 0.5 to 1 second. Security features in GPRS is provided by GSM network.

GPRS Architecture
Global System for Mobile Communication (GSM) circuit-switch architecture does not support the GPRS packet-switch architecture. Thus, GPRS requires its own network architecture. Several networks and databases e.g. Mobile Station (MS), Base Station Subsystem (BSS), Home Location Register (HLR), Visitor Location Register (VLR) in existing GSM network are modified in GPRS network.

GPRS architecture introduces the following network nodes to GSM architecture.

Serving GPRS Support Node (SGSN)

Gateway GPRS Support Node (GGSN)

Mobile Station (MS)

Base Station System (BSS)

Home Location Register (HLR)

Visitor Location Register (VLR)



1.Serving GPRS Support Node (SGSN): In GPRS network SGSN is equivalent to MSC. Packets of data between MSC and Public Switch Data Network (PSDN) are transferred and received by SGSN.

2.Gateway GPRS Support Node (GGSN): GSM databases e.g. HLR and VLR are supported by GGSN. It also interacts with external packet-switch networks.

3.Mobile Station (MS): In GPRS network MS consists of Mobile Terminal (MT) and Terminal Equipment (TE). A computer attached to MT is called a ME. Through air, MT communicates with the BSS.

4.Base Station System (BSS): In BSS, Base Transceiver Station (BTS) and Base Station Controller (BSC) are modified to support GPRS channel coding schemes BTS is modified while to forward calls to Mobile Switching Centre (MSC) and data to SGSN through Packet Control Unit (PCU), is supported by BSC. One SGSN is served by one BSC.

5.Home Location Register (HLR): In GPRS, HLR contains information about routing. To map an MS to one or more GGSNs, update the SGSN and to store the Internet Protocol (IP) address, this information is accessed by both SGSN and GGSN.

6.Visitor Location Register (VLR): In GPRS. VLR contains the SGSN number and this number indicates the MS currently served by the SGSN.

WiMAX Wireless Broadband Info

WiMAX stands for World Interoperability for Microwave Access that enables the actual broadband wireless network with high speed. WiMAX operate same like WiFi but WiFi operate with some limitation like it is base band technology and cover only 100 feet radius with slow speed. WiMAX covers a radius of 50 Km and work with the speed of 70 Mbps. WiMAX is the replacement of the wired broadband. In wired broadband connection, we can transmit data with 512 Kbps to 10 Mbps speed and more, for example DSL broadband and cable broadband. In future all new desktop and notebook computers will be incorporated with WiMAX technology. With this technology you will be connected to the internet even you are driving your car with the speed of 120 Km.

Tips about DSL ISPs

There are many DSL service providers are working in market and offering DSL connection with different rates. Some are providing high speed connection with many extra benefits like first one month free, free modem and may be some free software (popup blocker, antivirus) download option. Mostly DSL provider offering traffic allowed up to 1 GB with basic 128 Kbps internet connection. But if you want to play online games, downloading audio or video files and uploading data, then the traffic allowed(1 GB) in one month from DSL provider will be the main issue for you. May be some DSL provider offering you up to 2 GB or more with the same rates. Always consider their customer support and modem warranty strategy whether they are offering free or paid service in case any problem after getting connection. Some DSL providers offer more benefits for you with DSL connection to compete with others services provider like first one month free, free modem and some antivirus software. Meanwhile some ISP offers you discount package if you will pay them 6 to 8 months advance internet monthly payments. At the end I recommend you, always choose your nearest DSL service provider for good internet speed with minimum problem because distance also matter in DSL.
