When using RFID radio Frequency Identification What is an Arpt active reader passive tag )?

An Active Reader Passive Tag (ARPT) system has an active reader, which transmits interrogator signals and also receives authentication replies from passive tags. An Active Reader Active Tag (ARAT) system uses active tags awoken with an interrogator signal from the active reader.

How far can RFID be read?

Generally speaking RFID tag maximum read distances are as follows: 125 kHz.and 134.3 kHz. Low Frequency (LF) Passive RFID Tags -read distance of 30 cm (1 foot) or less – usually 10 cm (4 inches) unless you are using a very large tag which can have a read distance of up to 2 meters when attached to metal.

Why should wireless networks not use any frequency or channel?

The reason that certain channels aren’t the best choice to use is because they have interference. There are a couple different ways this interference is caused: Co-Channel interference results when there are numerous devices all competing for time to talk on the same channel.

What is the purpose of a probe response?

If they have compatible data rates, a probe response is sent advertising the SSID (wireless network name), supported data rates, encryption types if required, and other 802.11 capabilities of the AP. A mobile station chooses compatible networks from the probe responses it receives.

What are the two most important information contained in the beacon frames?

Each beacon frame (or probe response) contains a lot of information about the specific SSID being offered. While not a complete list, the really important items are as follows: SSID Name: 1-32 character name of the network. BSSID: Unique Layer 2 MAC address of the SSID.

Which fiber implementation is often referred to as FTTP?

Point-to-multipoint FTTP technology is commonly referred to as passive optical network (PON) technology. … There are various types, including broadband PON (BPON), gigabit PON (GPON) and Ethernet PON (EPON).

What is QoS data frame?

Data frames with a value of 1 in the QoS subfield of the Subtype field (Bit7) are collectively referred to as QoS data frames. Each of these data subtypes contains QoS in their names, and this frame format is distinguished by the presence of a QoS Control field in the MAC header.

Which device has most network ports?

Hub is commonly used to connect segments of a LAN (Local Area Network). A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network.

Which protocol is a path vector routing protocol?

Border Gateway Protocol (BGP) Border Gateway Protocol (BGP) is an example of a path vector protocol. In BGP, the autonomous system boundary routers (ASBR) send path-vector messages to advertise the reachability of networks. Each router that receives a path vector message must verify the advertised path according to its policy.

Is OSPF a distance vector protocol?

OSPF is not a distance-vector protocol like RIP, but a link-state protocol with a set of metrics that can be used to reflect much more about a network than just the number of routers encountered between source and destination. In OSPF, a router attempts to route based on the state of the links.

What is path state routing?

Link state routing is a technique in which each router shares the knowledge of its neighborhood with every other router in the internetwork. Every router that receives the packet sends the copies to all its neighbors. … Finally, each and every router receives a copy of the same information.
