These terms define the working frequencies of GSM cellular phones on particular networks. There are 3 working frequencies - 900/1800/1900. GSM phones that work on 2 frequencies are called dual band while those that work on 3 frequencies are called tri-band. This facility allows the user to use his/her cell on different networks, and beneficial for international roaming.

A tri-band phone operates at three supported frequencies, such as 900/1800/1900 MHz or 850/1800/1900 MHz. A dual-band phone operates at two frequencies, such as 850/1900 MHz or 900/1800 MHz. See similar questions...

Dual band phones tend to work in the UK and Europe and most of the world (GSM 1800 and GSM 900), whilst in America you need a phone that can take GSM 1900 so most often a Tri band or Quad band phone is the best option. See similar questions...

You can get a dual band antenna that will cover all 3 modes (analog, digital cellular and digital pcs) or, as mentioned above, focus on where you're having reception problems. First find out what network your phone is actually using in your city by calling your service provider. Just ask if you're in a 800MHz range area or 1900MHz range area. See similar questions...

Tri band refers to the physical frequencies which your mobile phone can operate on. The three international frequencies ranges or bands reserved for GSM are 900MHz, 1800MHz and 1900MHz. In Australia, as at the time of publication, most GSM networks still use only the 900MHz frequency band. Soon, GSM carriers will be upgrading their networks to support the 1800MHz band also.

Real-time activities are "live" and immediate. In the context of an online course, a real-time session is one in which all participants are logged on at the same time and interacting at more or less the same pace as one would in a face-to-face setting. A familiar example of real-time communication on the Internet is live chat. Asynchronous activities, on the other hand, are those in which participation is not concurrent or live.

Dual band refers to cellular telephones that are able to operate on two different frequency bands, such as GSM 900 and GSM 1900. If a phone has dual band capability, it automatically scans for the strongest signal and switches Networks - even during a call within the same operator's Network. See similar questions...

A Tri-band GSM phone operates on the three internationally designated GSM frequencies- 900, 1800 and 1900 MHz. The capability to seamlessly handover between the three bands offers operators major capacity gains. See similar questions...

This refers to Mirage’s deployment model: not physically in-line. Despite this out-of-band connection, its behavioral algorithms allow Mirage NAC to function as effectively as in-line threat mitigation devices. By deploying out-of-band, Mirage NAC installs and configures easily without complicated network reconfigurations and without introducing a risk of latency or failure in the network.
