Is Satellite Internet for You?
Is Satellite Internet for You?
- Do you have access to a telephone line or a cable TV line? For those that aren’t plugged into these networks, satellite internet is the way to go. Satellite internet delivers internet access through over-the-air satellite waves, and therefore aren’t limited by the physical infrastructure the same way DSL, Cable, and even Fiber Optics broadband services are. That means, for those in remote parts of the world, or those that are in a mobile set-up (e.g. mobile home), satellite internet makes plenty of sense.
- Do you have space for a satellite dish? Sounds obvious, but it’s necessary to have space to install an outdoor dish with a clear line-of-sight to the southern sky. If unsure, it might be worth it to consult with a provider’s technician on whether your set-up is optimal for satellite service before signing any agreement, especially for multi-story apartment or condominium units.
- Do you live somewhere with inclement weather? On the flipside, the fact that satellite internet is not tied to a physical infrastructure means its subject to connectivity problems with moisture and precipitation in the atmosphere. Heavy storms may even cause prolonged periods of signal outages. It’s, therefore, important to take into consideration the normal weather patterns in and around your area.
WiMAX Wireless Broadband Info
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.
Objective of WiMAX
- Superior Performance
- Flexibility
- Advanced IP-Based Architecture
- Attractive Economics
IEEE 802.16 Specifications
- Range 30 mile radius from the base station for LOS (line-of-sight).
- Range 4-6 miles radius from the base station for NLOS (Non-line-of-sight)
- Maximum data speed supported as 70 Mbps.
- Licensed frequency band: 2- 11 GHz
- Un-licensed frequency band: 10- 66 GHz
- Line of sight is not needed between user and the base station unless very high date rates are required at the user premises.
How to improve your Wireless internet and network connection?
How to improve your Wireless internet and network connection?
Microsoft Windows gives you a notification whenever your wireless network has a weak signal. This is a sign that you should improve your wireless network. When you get this notification, it means that the wireless connection is not as reliable or high-speed as it's supposed to be. In fact, the wireless connection signal may be completely lost in certain areas of the house. If you would like to improve your wireless network signal, you should carry out a few of these tips. These tips will extend the wireless range. They will also improve the overall performance as well as reliability of the wireless network.
Re-position the wireless router (or wireless access point) to the centre of the house.
Place the router away from walls.
Place the router off the floor.
Place the router away from metal objects.
Instead of using a standard antenna which you get with the router, use a hi-gain one. If the standard router is placed by an outer wall, part of the wireless signals will be directed outside the house. This will also waste the power of the router. Hi-gain antennas send the wireless signals in a single specific direction which you are able to aim on the path where you need them a large amount.
Add a wireless repeater to extend the signal range.
Change the wireless router's channel to increase the strength of its signal. You can do that through the configuration page of the router. The computer will detect the new channel itself.
Update your firmware updates for your router through the manufacturer's website. Update your network adapter driver through the Windows Update feature of Windows 7 and Vista or visit the website www.update.microsoft.com for Windows XP.
Upgrade 802.11b devices to 802.11g or buy a new 802.11 g equipment. It is five times faster than an 802.11b device.
System software
System software is computer software designed to operate the computer hardware and to provide a platform for running application software.[1][2]
The most basic types of system software are:
Computer purchasers seldom buy a computer primarily because of its system software (But purchasers of devices like mobile phones because of there system software, as is the case with the iPhone, as the system software of such devices is difficult for the end-user to modify). Rather, system software serves as a useful (even necessary) level of infrastructure code, generally built-in or pre-installed.
In contrast to system software, software that allows users to do things like create text documents, play games, listen to music, or surf the web is called application software.[4]
Specific kinds of system software include:
The most basic types of system software are:
- The computer BIOS and device firmware, which provide basic functionality to operate and control the hardware connected to or built into the computer.
- The operating system (prominent examples being Microsoft Windows, Mac OS X and Linux), which allows the parts of a computer to work together by performing tasks like transferring data between memory and disks or rendering output onto a display device. It also provides a platform to run high-level system software and application software.
- Utility software, which helps to analyze, configure, optimize and maintain the computer.

[edit] Types of system software programs
System software helps use the operating system and computer system. It includes diagnostic tools, compilers, servers, windowing systems, utilities, language translator, data communication programs, database systems and more. The purpose of system software is to insulate the applications programmer as much as possible from the complexity and specific details of the particular computer being used, especially memory and other hardware features, and such accessory devices as communications, printers, readers, displays, keyboards, etc.Specific kinds of system software include:
- Loaders
- Linkers
- Utility software
- Desktop environment / Graphical user interface
- Shells
- BIOS
- Hypervisors
- Boot loaders
- Database Management Systems(SQL, NoSQL)
