Streamline of information system

Benefits
Streamline Dispatch Center Information with HyperionMIS
The InterAct Management Information System is equipped with easy record keeping and rapid report generation to provide dispatch centers with the tools necessary to perform at the highest level of efficiency. With HyperionMIS, call centers have the ability to achieve exceptional professionalism and work to provide their community with an extremely advanced public safety system.
Easy setup provides quick and easy access to all the necessary components of the inner workings of HyperionMIS. Any changes, upgrades, or modifications in programming are far easier to manage than ever before.
Simple Integration makes it possible for HyperionMIS to interoperate with multiple9-1-1 Controllers from different manufacturers at the same time.
Flexible design of HyperionMIS allows for many different configurations to suit the particular needs of the dispatch center, including Stand-Alone, Enterprise, and Enterprise with Data Collection only.
Instant reporting allows users to select and print a variety of prepared reports on demand or schedule them for automatic printing at a later date
Information management monitors and records data, providing the dispatch call center with the necessary resources to ensure maximum productivity and evaluate staff members accordingly.
ACD Statistic data collection monitors and records data specific to automatic call distribution for call centers (where used)
Sophisticated security prevents records and reports from being accessed by anyone other than approved individuals. Data also cannot be modified or altered, ensuring consistency and accuracy for the dispatch center.
Wireless and VOIP call statistics provides statistical call data for incoming wireless calls and Voice over IP (VOIP) calls.

Wi-Fi




What Is WiFi?

A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens:

A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.


A wireless router receives the signal and decodes it. It sends the information to the Internet using a physical, wired Ethernet connection.

The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.
The radios used for WiFi communication are very similar to the radios used for walkie-talkies, cell phones and other devices. They can transmit and receive radio waves, and they can convert 1s and 0s into radio waves and convert the radio waves back into 1s and 0s. But WiFi radios have a few notable differences from other radios:


They transmit at frequencies of 2.4 GHz or 5GHz. This frequency is considerably higher than the frequencies used for cell phones, walkie-talkies and televisions. The higher frequency allows the signal to carry more data.

They use 802.11 networking standards, which come in several flavors:


802.11a transmits at 5GHz and can move up to 54 megabits of data per second. It also uses orthogonal frequency-division multiplexing (OFDM), a more efficient coding technique that splits that radio signal into several sub-signals before they reach a receiver. This greatly reduces interference.


802.11b is the slowest and least expensive standard. For a while, its cost made it popular, but now it's becoming less common as faster standards become less expensive. 802.11b transmits in the 2.4 GHz frequency band of the radio spectrum. It can handle up to 11 megabits of data per second, and it uses complimentary code keying (CCK) coding.


802.11g transmits at 2.4 GHz like 802.11b, but it's a lot faster -- it can handle up to 54 megabits of data per second. 802.11g is faster because it uses the same OFDM coding as 802.11a.
802.11n is the newest standard that is widely available. This standard significantly improves speed and range. For instance, although 802.11g theoretically moves 54 megabits of data per second, it only achieves real-world speeds of about 24 megabits of data per second because of network congestion. 802.11n, however, reportedly can achieve speeds as high as 140 megabits per second.

WiFi radios can transmit on any of three frequency bands. Or, they can "frequency hop" rapidly between the different bands. Frequency hopping helps reduce interference and lets multiple devices use the same wireless connection simultaneously.


WiFi Hotspots

If you want to take advantage of public WiFi hotspots or start a wireless network in your home, the first thing you'll need to do is make sure your computer has the right wireless gear. Most new laptops and many new desktop computers come with built-in wireless transmitters. If your laptop doesn't, you can buy a wireless adapter that plugs into the PC card slot or USB port. Desktop computers can use USB adapters, or you can buy an adapter that plugs into the PCI slot inside the computer's case. Many of these adapters can use more than one 802.11 standard.

Once you've installed your wireless adapter and the drivers that allow it to operate, your computer should be able to automatically discover existing networks. This means that when you turn your computer on in a WiFi hotspot, the computer will inform you that the network exists and ask whether you want to connect to it. If you have an older computer, you may need to use a software program to detect and connect to a wireless network.
Being able to connect to the Internet in public hotspots is extremely convenient. Wireless home networks are convenient as well. They allow you to easily connect multiple computers and to move them from place to place without disconnecting and reconnecting wires. In the next section, we'll look at how to create a wireless network in your home.
