Planning a digital signage system.
How to plan a digital signage project.
Considering the many available digital signage solutions might seem like an overwhelming task. But taking some time to research and understand your options will... more/see it nowbe well worth the investment for your institution. Follow these key steps:
1. You need to understand and articulate the objective at the start. Clearly define the goals and determine how you will measure and analyze against the goals.
Determine what information you want to communicate and for what purpose. You may want it to give you one or more of the following:
• Sales uplift.
• Brand messaging.
• Entertainment for waiting customers.
• Better internal communications.
• Public messaging.
• Third-party advertising.
It is not only imperative to understand what you want the signage to accomplish but also how it will be evaluated. In short, “How will the success or failure of the system be judged and by whom?” What metrics of judgment will be used: ROI, ROO, or other qualifiers?
2. Clearly define the content: The success of any digital signage system starts, of course, with the content. It must look fresh, exciting, and professional. Who will create it and how will it be presented? Do you have internal resources and expertise, or will you need to outsource content creation? A good source of creative and editorial help can be found in aspiring graphic designers culled from the student ranks, in addition to your school’s art department, yearbook and newspaper staffs, and TV studio (if you have one).
3. Invest the time to understand your options: Once you’ve decided on content, you need to consider the infrastructure that will deliver it and study your display options: LCD vs. plasma? RSS feeds? Live video? Remote management? Playback verification? The options will seem limitless, so taking time to sort through them is imperative.
4. Involve all the appropriate stakeholders: The communications/information department should be involved at the start, considering that your digital signage will likely be used for external community relations. If it‘s a K–12 application, you’ll need to include not only your district’s superintendent, principals, purchasing personnel, and IT staff, but also quite possibly instructional technology and AV staff, as well as maintenance, curriculum, athletic, and cafeteria directors.
5. Figure out how you’re going to pay for it: Digital signage is often viewed by some as a luxury item? —? particularly in the face of shrinking school budgets. But because it can also be used as a tool for emergency communications and notification, administrators can easily make the case that digital signage is a must-have component of any crisis plan — especially in this day and age when school violence incidents capture news headlines. Consider government sources of funding for your digital notification system (federal funds are available from the U.S. Department of Homeland Security for pre-disaster mitigation and preparedness, as well as the U.S. Department of Justice, for instance). Whether it’s earmarked entirely as an IT expenditure or apportioned across multiple departments in your budget, you need a spending roadmap in addition to a developmental one. The hardest part with this may be determining the total cost of ownership over the life of the system, including any nickling-and-diming with ongoing licenses and upgrades. College administrators, however, can easily make the case from a cost-savings perspective. Having to constantly update traditional signage across a campus can be quite costly. Paper signage is expensive to print and replace regularly. With digital signage, no printed material is necessary, so both time and cost savings can be made, and the environmental impact is minimized.
6. Decide how to implement the solution: Based on your deployment size and scope, decide if you can implement it in-house or if you need the help of a professional integrator. A number of “out-of-the box” systems can be set up with relative ease. But the more dynamic and complex the system, the more complicated the implementation and ongoing management? — ?and the more likely you’ll need outside help.

Black Box Explains...Wireless Ethernet standards.
The precursor to 802.11b, IEEE 802.11 was introduced in 1997. It was a beginning, but 802.11 only supported speeds up to 2 Mbps. And it supported two entirely different... more/see it nowmethods of encodingFrequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS). This led to confusion and incompatibility between different vendors equipment.
802.11b is comfortably established as the most popular wireless standard. With the IEEE 802.11b Ethernet standard, wireless is fast, easy, and affordable. Wireless devices from all vendors work together seamlessly. 802.11b is a perfect example of a technology that has become both sophisticated and standardized enough to really make life simpler for its users.
The 802.11b extension of the original 802.11 standard boosts wireless throughput from 2 Mbps all the way up to 11 Mbps. 802.11b can transmit up to 200 feet under good conditions, although this distance may be reduced considerably by the presence of obstacles such as walls.
This standard uses DSSS. With DSSS, each bit transmitted is encoded and the encoded bits are sent in parallel across an entire range of frequencies. The code used in a transmission is known only to the sending and receiving stations. By transmitting identical signals across the entire range of frequencies, DSSS helps to reduce interference and makes it possible to recover lost data without retransmission.
The 802.11a wireless Ethernet standard is new on the scene. It uses a different band than 802.11b—the 5.8-GHz band called U-NII (Unlicensed National Information Infrastructure) in the United States. Because the U-NII band has a higher frequency and a larger bandwidth allotment than the 2.4-GHz band, the 802.11a standard achieves speeds of up to 54 Mbps. However, its more limited in range than 802.11b. It uses an orthogonal frequency-division multiplexing (OFDM) encoding scheme rather than FHSS or DSSS.
802.11g is an extension of 802.11b and operates in the same 2.4-GHz band as 802.11b. It brings data rates up to 54 Mbps using OFDM technology.
Because it's actually an extension of 802.11b, 802.11g is backward-compatible with 802.11b—an 802.11b device can interface directly with an 802.11g access point. However, because 802.11g also runs on the same three channels as 802.11b, it can crowd already busy frequencies.
Super G® is a subset of 802.11g and is a proprietary extension of the 802.11g standard that doubles throughput to 108 Mbps. Super G is not an IEEE approved standard. If you use it, you should use devices from one vendor to ensure compatibility. Super G is generally backwards compatible with 802.11g.
80211n improves upon 802.11g significantly with an increase in the data rate to 600 Mbps. Channels operate at 40 MHz doubling the channel width from 20 MHz. 802.11n operates on both the 2.4 GHz and the 5 GHz bands. 802.11n also added multiple-input multiple-output antennas (MIMO).
Multiple-Input/Multiple-Output (MIMO) is a part of the new IEEE 802.11n wireless standard. It’s a technique that uses multiple signals to increase the speed, reliability, and coverage of wireless networks. It transmits multiple datastreams simultaneously, increasing wireless capacity to up to 100 or even 250 Mbps.
This wireless transmission method takes advantage of a radio transmission characteristic called multipath, which means that radio waves bouncing off surfaces such as walls and ceilings will arrive at the antenna at fractionally different times. This characteristic has long been considered to be a nuisance that impairs wireless transmission, but MIMO technology actually exploits it to enhance wireless performance.
MIMO sends a high-speed data stream across multiple antennas by breaking it into several lower-speed streams and sending them simultaneously. Each signal travels multiple routes for redundancy.
To pick up these multipath signals, MIMO uses multiple antennas and compares signals many times a second to select the best one. A MIMO receiver makes sense of these signals by using a mathematical algorithm to reconstruct the signals. Because it has multiple signals to choose from, MIMO achieves higher speeds at greater ranges than conventional wireless hardware does. collapse
