The Promise: Offer reliable, affordable broadband in geographic areas around the world where terrestrial communications are unavailable, inefficient or just too expensive. Share the satellite bandwidth amongst retail locations and consumers by establishing your own Wi-Fi Hotspot. Imagine end customers conveniently checking their email, contacting their office, clients, conducting business, chatting with friends and family, checking the traffic, weather and reading their local newspaper online from the comfort of their table.

The Need: In many countries, few homes or business in rural areas (or metropolitan area in some cases) have access to broadband internet connections. Neither DSL nor cable is readily available outside major cities, and as a result, most homes and businesses still rely on slow dialup access.

The Applications: Several successful applications are developed to take advantage of the new technology. Schools and colleges, for example, can provide high-speed access to rich multimedia web sites to their students. They are also benefiting from the same e-mail facilities as students in major cities.

The tourism industry in particular can benefit from broadband access, including independent hotels and other tourist destinations. For example, they are able to provide full details on their products or services, such as pictures of holiday cottages available for rent, and distribute them anywhere.

Livestock farming also often makes up a large part of a local rural economy, and this industry will notice measurable gains as a result of the new technology. For example, it is possible to keep databases on the movement of cattle throughout the region, noting when all animals were born, bred, and sold.

Perhaps most importantly, pricing for these broadband services is extremely competitive. Advantech Satellite Networks' DVB-RCS system is capable of supporting tens of users behind a single high bit rate terminal, thereby supporting an entire community via Wi-Fi or Wimax access. SatNet's customers are benefiting from local wireless loop solutions optimized for use with our DVB-RCS system.

Advantech Satellite Networks' solution integrates our DVB-RCS satellite network with radio access networks using optimized wireless edge router technology.

The distribution of media content over a two-way satellite system is often required in today's market. Advantech Satellite Networks' DVB-RCS satellite network is used to satisfy the requirements of applications such as distance learning systems, satellite news gathering, corporate presentations, or publicity/digital signage. The solution implemented is based on locating a media stream server at the gateway. This media stream server distributes media content to sites located behind terminals via multicast streams or unicast streams. The distributed media content can be archived media files or a live stream. The media source can be located at the gateway or behind a terminal. A media distribution network architecture includes three major components:

• The media producer is the component responsible for taking a source of media content (files, DVD, microphone, video camera), combining media types, encoding it and producing a media stream. This media stream can be sent live to the media stream server or stored locally for future distribution.
• The media stream server located at the gateway distributes the media content to the media players via multicast or unicast streams. This media content can be locally stored or it can be received from a media producer via a unicast stream.
• The media player is the client application that plays the received media streams from the server.

The advanced bandwidth management and quality of service (QoS) features of SatNet's DVB-RCS system allow the user to throttle the delivery of the required media content when it's needed and across the network of end users where it's needed.

IP allows a unified delivery of multiple services beyond traditional video services. It allows the delivery of services to business using a single, dynamic network infrastructure. When it comes to service differentiation, IPTV opens satellite service providers to next-generation services, including push video-on-demand, an alternative to network video-on-demand. IPTV is not only coming on fast, but also is arriving at a time when the customer knows that he can exercise absolute control over the content.

Satellite faces a few big challenges as the IPTV race gets underway, such as the lack of a ubiquitous, two-way network. To effectively and efficiently handle the growth of IPTV, satellite service providers must deal with transmission, target customers and service differentiation methods. They will need to embrace DVB-S2 and MPEG4/AVC to save bandwidth; satellite service providers that deliver content to regional wired or wireless operators must customize their programming line-up for local customers. Alternatively, operators can also use satellite VSAT-based technology for "last mile" delivery, but will need to focus on the right edge solutions, to multiplex, encode and transcode content to deliver a more personalized content. Advantech Satellite Networks' DVB-RCS technology can be married effectively to the right edge solutions; our highly flexible and dynamic bandwidth management capability constitutes a perfect match for triple-play and video-on-demand requirements seen together with IPTV applications, in addition to video streaming.

Now that satellite communication is becoming more cost effective, with equipment more portable and versatile, it is proving to be a feasible alternative to terrestrial communication. By using satellite communications, “utilities” can substantially expand communications in the field, as well as lay the groundwork for interoperability with SCADA systems over time. Utilities can expect to see some significant improvements both in terms of ease of access and cost savings, which will impact more than just a field technician's ability to phone home.

With an Advantech Satellite Networks' DVB-RCS system, utilities can leverage communications capabilities to integrate their SCADA systems online to perform remote monitoring and control, trigger paging alarms, and other automated functions. Many sites require communications over the air, the Internet or PSTN (public switched telephone network) for ultimate connection with the home office. Field personnel can access monitoring and control equipment from virtually any location. Low power and out-door modem solutions are available from SatNet.

Solar Powered Implementation: The power to run the terminal comes from a bank of deep cycle batteries, a low wattage solar panel, an inverter and the sun. The inverter provides 120/220VAC power for the terminal and end user devices such as computers, (pay) phones and even nighttime lighting. The inverter is connected to the deep cycle batteries. The power from the solar panel is fed to via a solar charge regulator, which maintains the batteries at their optimum charge state. To conserve power, the outdoor RF amplifier of the terminal can be turned off when the terminal is not transmitting any traffic.

The Internet has become a mission-critical application for small and medium size businesses in today's global economy. Loss of internet connectivity can result in lost direct sales opportunities from online purchases and sever external data communications with teleworkers, branch offices, partners and suppliers. The loss of access to real-time information on sales, inventory, and connectivity to other applications and services further adds to losses by decreasing efficiency and worker productivity. Serious businesses require around-the-clock network reliability and availability. Because no network, however robust, is 100% fail-proof, any business-class service must include some form of redundancy.

A redundant network and/or link to the internet ensures a business against downtime and the consequent loss of revenues and employee productivity. Until now, backup was only available on traditional leased line services. With the availability of backup solutions over satellite, businesses now have an affordable alternative allowing them to connect to the internet bypassing any surrounding terrestrial infrastructure and to remain connected to the main office and branches, offices or stores. Using an intelligent customer premise router, internet access failures can be detected and switched quickly in order to maintain connectivity.
