QoS The Quality of Service (QoS) feature is based on the 802.16 standard and

defines the classes, service flows, and packet identification rules for

specific types of traffic. The main priority of QoS is to guarantee a reliable

and adequate transmission quality for all types of traffic under conditions

of high congestion and bandwidth over-subscription.

RADIUS Server Remote Authentication Dial In User Service (RADIUS) is a client/server

networking protocol that runs in the application layer, by using UDP as

transport and provides centralized Authentication, Authorization, and

Accounting (AAA) management for computers to connect and use a

network service. The RADIUS server is a background process that serves

the following three functions:

• To authenticate users or devices before granting them access to a

network

• To authorize those users or devices for certain network services

• To account the users for usage of the provided services.

Rogue Devices Rogue devices include Rogue 802.11n AP devices and Rogue wireless

devices (AP/STA/WDS/ADHOC), that are not authorized and secure.

RTS Frame A node wishing to send data initiates the process by sending a

Request-to-Send (RTS) frame.

RIP Routing Information Protocol (RIP) is used between routers to update

routing information so that a router automatically ‘knows’ which port to

use for a certain destination IP address.

Router Routers forward packets from one network to another based on routing

information. A router uses a dynamic routing protocol like RIP or static

routes to base its forwarding decision on.

ScanTool A computer program that can be used to retrieve or set the IP address of a

locally connected unit.

Simple Network Management

Protocol (SNMP)

A protocol used for the communication between a network management

application and the devices it is managing. The network management

application is called the SNMP manager and the devices it manages will

have SNMP agents. Not only the unit but also almost every network device

contains a SNMP agent. The manageable objects of a device are arranged

in a Management Information Base, also called MIB. The Simple Network

Management Protocol (SNMP) allows managers and agents to

communicate for accessing these objects.

Single-Band Single-band refers to a device's ability to function only on one frequency

band.
