About Broadband Network
WiMax
WiMAX (Worldwide Interoperability for Microwave Access) is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations while Wi-Fi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).
WiMAX extends the benefits of wireless broadband beyond Wi-Fi hotspots, enabling superior connectivity in both urban and rural environments. With its faster download speeds and higher bandwidth, WiMAX also opens up an exciting new wave of rich voice, data, and multimedia applications for a wide variety of business, communication, entertainment, and educational applications.
Based on the IEEE 802.16e standard, WiMAX combines superior data rates with greater scalability, lower costs, and reduced network complexity, making it easier and more cost-effective to deploy and operate than current mobile wireless data solutions.
As a result, it provides an extremely compelling solution not just for traditional carriers but also for innovative new wireless broadband deployments and business models in rural areas, emerging markets, and even “closed” networks in university and school campuses.

E-Learning
With the proliferation of state-of-the-art wireless broadband technologies, the emergence of the newest, low-cost personal computing devices such as netbooks, and the development of innovative new online educational applications, new markets in e-Learning are rapidly opening up as countries throughout the world look to improve educational standards and increase competitiveness in the global economy.
Market:
By 2010, the size of this market is projected to swell to $52.5 billion worldwide, according to Global Industry Analysts, Inc., a research company based in San Jose, California, and is expected to continue to grow rapidly in the years ahead.
Developments in internet and multimedia technologies are the basic enabler of e-learning, with content, technologies and services being identified as the three key sectors of the e-Learning industry.
Benefits:
e-Learning can provide major benefits for the organizations and individuals involved.
- Affordable quality education: The fact that instructors of the highest caliber can share their knowledge across borders allows students to attend courses across physical, political, and economic boundaries. Recognized experts have the opportunity of making information available internationally, to anyone interested at minimum costs. This can drastically reduce the costs of higher education, making it much more affordable and accessible to the masses. An internet connection, a computer, and a projector would allow an entire classroom in a third world university to benefit from the knowledge of an opinion leader.
- Convenience: in many contexts, eLearning is self-paced and the learning sessions are available 24x7. Learners are not bound to a specific day/time to physically attend classes. They can also pause learning sessions at their convenience.
- Environment friendly: e-Learning allows people to avoid travel, thus reducing the overall carbon output. The fact that it takes place in a virtual environment also allows some reduction of paper usage. With virtual notes instead of paper notes and online assessments instead of paper assessments, eLearning is a more environmentally friendly solution.

Digital Signage
Digital signage is a form of electronic display that shows information, advertising and other messages.
Taking the form of LCD, LED or plasma display, Digital signage is rapidly growing with a variety of indoor and outdoor applications.
Applications:
Some of the most common applications of digital signage are as follows:
- Public information – news, weather and local information, such as fire exits and traveler information
- Internal information - corporate messages, health & safety, news, etc.
- Advertising – either related to the location the signage is in or for general advertising
- Brand building – in-store digital signage to promote the brand and build a brand identity
- Influencing customer behavior – directing customers to different areas, increasing the dwell time on the store premises
- Enhancing customer experience – such as reduction of perceived wait time in restaurants, banks, etc.
Content for digital signage:
Content can be anything designed and displayed on the screens. It can be text, images, animations, video, audio, and interactivity. In many digital signage applications, content must be regularly updated to ensure that the correct and up to date messages are being displayed. This can either be done manually, or through a scheduling system, or by linking in with an outside feed through local or broadband networks.
NDT’s digital signage solutions are designed to deliver the content through WiMAX broadband networks to its displays that range from small TVs to stadium-size LED screens.
