 Technology Corner: OFDM - Tubocharge Your Wireless Networks
In today's world of ever increasing wireless license free usage, what has considered long range performance are now short range due to the increasing interference challenges of  shared spectrum, or license free fair usage.  Along with the general challenges of signal-to-noise ratio, the main types of problems are inferior RF hardware design causing self-interference and fading owing to multipath effects, which occur when the same signal arrives at a receiver via different paths.  OFDM (orthogonal frequency division multiplexing) is a technique for increasing, i.e., tubocharge, the amount of information that can be carried over a wireless network, and it meets these challenges and has dealt with the unruly ways in which radio signals misbehaves in the real world.
OFDM is a wireless signal modulation technique which utilizes multiple subcarrier waves.  Compared to wider single carrier modulation to transport data information, smaller multiple carrier waves are divided to carry only a slice of the whole data information.  When wireless transmission is interrupted or corrupted, only the slice of the transmission is affected compared to the whole providing higher performance throughout the transmission process.  When all the mathematical language and formulation is not considered, OFDM is a method for chopping a large frequency channel into a number of subchannels.  The subchannels are then used in parallel for higher throughput.  
The IEEE 802.11a and IEEE 802.11g standards are designed based on OFDM.  OFDM is not a new technique.  Most of the fundamental work was done in the late 1960s, and U.S. patent number 3,488,445 was issued in January 1970.  Inscape Data outdoor wireless radios offer OFDM modulation and proprietary range extension algorithm for robust high-bandwidth capabilities offering immediate advantage over competing proprietary wireless technologies.
The widespread interests of OFDM become clear from a glance at OFDM characteristics. In 802.11a, OFDM provides raw data rates up to 54 Mbits/s in a 20-MHz channel. In addition to supporting high data capacity and resisting degradation from various types of radio effects, OFDM makes highly efficient use of the available spectrum. The latter characteristic will become crucial in coming years as wireless networks are built out. 
OFDM Simple Architecture Overcomes 
  • Noise
  • Signal to Noise Ratio Challenges
  • Multipath Fading
  • Adjacent Channel Interference
  • Non-Adjacent Channel Interference
OFDM is currently used in digital cable, DSL, digital TV, European Telecommunications' HiperLan, power-line networking products, and many more.  Table I list technology using OFDM as the robust and reliable modulation technique.  Cellular carriers are also considering migrating from CDMA or TDMA into OFDM for use in 4G cellular systems.  4G cellular systems consist of video, voice, and data.  Currently 3G networks cannot cost-effectively provide the whole Internet experience to the mobile user.  Because OFDM can overcome signaling transmission barriers and increase transmissions speeds, while dealing with unpredictable changes of the radio frequency environment.

Help Desk 1 of 2 : How to use the NVM1000 to playback and search recorded IP video 
To playback video using the NVM1000 software, make sure the program is running and simply click on the 'playback' button located in the upper right hand corner. This button has a picture of a camcorder. Once clicked, a screen with 'playback' written at the top will launch (See Fig.1). There will also be a calendar to the right. Select the appropriate disk where the recorder files reside and then select the required file which will be dated. You will notice that the recorded footage is color coded. The legend can be found below. The turquoise color represents manual recordings, the yellow color represents a scheduled recording, the purple color represents recorded footage triggered by motion detection, and finally, the pink color represents recorded footage triggered by an external sensor. Once a specific date in the calendar is selected, the corresponding files associated will be displayed below. To play a file, simply check the box and then click the 'play' button located at the very bottom. The software will then proceed to play the recorded footage. In addition, there are 3 boxes labeled 'all', 'multiple', and 'original'.  If 'all' is checked, all files in the box below will be checked.  If 'multiple' is checked, then this will enable playback of multiple channels. If 'original' is checked, it playback the file in its original size it was recorded in.


 Fig. 1 Shows the Playback Screen Where Playback of Recorded File Takes Place
If you notice in Fig.1 there are 3 drop-down menus labeled 'all page', 'all channel', and 'all data'. This is an available filter to help locate a specific file you are searching for. In the 'all page' drop-down menu, you will find, numbers 1 through 4 corresponding to pages 1, 2, or all.  The 'all page' drop-down menu is no longer used so it is best to leave this on 'all page'. To select a specific page between 1, 2, 3, or 4, fill in the appropriate bubble above the three drop-down menus.  In the 'all channel' menu you will find channels 1 through 16 and 'all'.  This is used to narrow your search down to a specific channel or camera's recorded footage.  The 'all data' menu is used to select the type of data you are searching for which includes data, IP address, time, and description.  If you select time, there will be a time filter which will allow you to select a time range. If you select IP address, you can manually type the IP address into the box and click search. If you select description, you can type any part of a file name into the search box and the results will be displayed.
Finally, toward the bottom, there is a box called 'select record folder type'.  There are four boxes here labeled manual, motion, schedule, and sensor.  You can select one or more to display the appropriate file type you would like displayed.

Help Desk 2 of 2: How to Use NVM1000's E-Map Feature 
Now we will look at the E-Map features and explore what exactly they do. E-Map is a tool that allows the user to select either, their own picture, their own map, or the default map of the world included in the NVM1000 software. You will be able to simply drag and drop the IP cameras onto the E-Map. 
Once you have the NVM1000 software open, click on the world map icon located to the left of the relay on/off switch. This will launch the E-Map feature. You can now use the default map or upload any other map you may have from your hard drive. The file must be a .BMP file in order to use this feature.  To add your own .bmp file, go to 'File' and then select 'New'. Simply browse to the location of your .bmp file and select it. Now you will see the 'Map list navigation' in the upper left hand corner.  Click on the 'needle' to the right and you get a drop-down list of all available .bmp images to select from. Simply click on one of the .bmp files and it will be shown in the map area.
Once the map has been selected, you can begin to place your IP cameras onto the map by dragging and dropping them. To view your available cameras, go to 'view' and select 'camera list view. This will show all available cameras. Click on a camera's IP address to see an icon of a camera appear underneath it. Now you can drag the camera icon onto your image shown in green in "Figure 1" below. To lock or unlock the drag feature, simply go to the 'option' menu, click either the 'drag lock' or 'drag unlock' icon. Another way to achieve this is to click the 'unlock' or 'lock' icon located right below the menu.  If you double-click any of the green points which correspond to cameras on the map, you will see the live feed of that camera (fig.2).

In addition, if an IP camera is streaming live, the green dot will be bright green in color. If it is not streaming live, then the green dot will be darker in color. This is shown below in Figure 1.  Whenever an IP camera is streaming live, it will be logged in the 'event log'. To view, simply go to the 'event log view'. This can be seen in the table shown in Figure 1.
