|
|
Term
| MAN (Metropolitan Area Network) |
|
Definition
| Network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). |
|
|
Term
| MIMO (Multiple Input-Multiple Output) |
|
Definition
| Antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). |
|
|
Term
| MPLS (Multi Protocol Label Switching) |
|
Definition
| Standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. |

|
Term
| MSC (Mobile Switching Center) |
|
Definition
| Switch used for call control and processing. The MSC also serves as a point-of-access to the Public Switched Telephone Network (PSTN - the fixed network). |
|
|
Term
| OFDM (Orthogonal Frequency Division Multiplexing) |
|
Definition
| Method of digital modulation in which a signal is split into several narrowband channels at different frequencies. |
|
|
Term
| PPTP (Point-to-Point Tunneling Protocol) |
|
Definition

|
Term
| SSL (Secure Socket Layer) |
|
Definition

|
|
Term
| VPN (Virtual Private Network) |
|
Definition
| Network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network. A virtual private network can be contrasted with an expensive system of owned or leased lines that can only be used by one organization. The goal of a VPN is to provide the organization with the same capabilities, but at a much lower cost. |
|
|
Term
| WiMAX (Worldwide Interoperability for Microwave Access) |
|
Definition
