Glossary

Wireless router is a network device that allows internet users to connect with several other computers without cables and use instead wireless access points or WLAN. It can also be a cable modem using wireless access point to communicate with local PCs and other devices. For this reason, any user of wireless routers, whether newbie or professional must be familiar with the terms and technologies that apply to this device.

802.11:

This is a set of standards that implements the wireless local area network (WLAN) computer communication using 2.4, 3.6 and GHz frequency bands. This version provides wireless communication in homes, offices and commercial establishments.

  • 802.11a is an amendment of its predecessor that adds higher data rates of Mbit/s using the 5 GHz band.
  • 802.11 b has a maximum rate data of 11 Mbit/s using the same CSMA/CA media access method as the original standard.
  • 802.11g is an amendment of 802.11 that extends as high as 54 Mbit/s but with the same 2.4 GHz band 802.11b. This specification is under the marketing name of Wi-Fi used worldwide.

Dual Band

Dual Band is wireless router that has more than one band, or frequency connected to the wireless router. It allows you to connect through the 5 GHz band your laptop and your Wi-Fi enabled TV. Today’s technology, double frequencies to connect with have become extremely useful.

Encryption

Encryption is a way of protecting the confidentiality of date. Examples are the use of:

  • RC4 acronym of Rivest Cipher 4 which is a symmetric cryptography algorithm and one mostly used in encryption algorithm for its simplicity and speed.
  • TKIP means Temporary Key Integrity Protocol which is a security protocol used in wireless networking standard.
  • WEP is also called Wired Equivalent Privacy which is a weak security algorithm for 802.11 networks.
  • WPA™ or Wi-Fi Protected Access is an improved security stand used in wireless network to give strong data protection and control network access.
  • WPA2™ or Wi-Fi Protected Access 2 is a better security method adopted by WPA for wireless networks of enterprises and Wi-Fi users with a high level of certainty that only authorized users can access the wireless network.

Firewall

Firewall is a software or hardware between two networks which hinders access of unauthorized users. It makes the network appear invisible to avoid unwanted users from using files and systems on PCs.

Hotspot

Hotspot is a location for users using Wi-Fi laptops and other enabled devices to gain access to Internet. Often located in airport lounges, coffee shops, hotels, trains stations etc., it may charge fees or offer free service.

LAN

LAN means local area network connecting PC’s and other devices together within the same area. The connection is faster and good for internet connections, printer files and drives. These devices are joined as a wired configuration known as wireless local area network (WLAN).

MAC address

MAC stands for Media Access Control address. This is a unique hardware ID number that identifies each network device; either a computer, printer, router, wireless adaptor, etc.

MIMO

MIMO is Multiple-Input-Multiple-Output. Used as an advanced signal processing technology, it uses multiple receivers and transmitter with both clients and access points to get data throughput speeds up to 100 Mbps.

Port Speed

Port speed is data transmission rate of an input/output channel. Ports are found at the back of wireless routers where connections are made with many devices as laptops, smartphones and table computers. Port speeds are either in the 100 Mbps or the 1000 Mbps variety. The best buy in port speed has 1 Gbps port.

Repeater

Wireless repeater is a device that extends the coverage of an existing wireless router by relaying its signal. Unlike wireless bridges and routers, it does not do intelligent routing..

Router

A router is a device that connects two or more data lines from different networks.

  • G router is a wireless router that uses 802.11 g wireless Ethernet standard and has a maximum speed of 54 mbps.
  • N router carried data 2-4 times as fast as the fastest previous “G” standard. It runs at 50 t0 144 Mbps determined by its enhanced features enabled and the measurement between wireless sender and receiver.
  • Wireless n router is an N router which has two antenna’s: one for transmitting and another for receiving.

SSID

SSID is an extraordinary 32-character name of a network or identifier that differentiates one wireless LAN from another. When you name your wireless network give a unique name for security reasons. An SSID consists of alphabets and numbers with a maximum of 32 characters.

Speeds

Speeds used in connection with wireless routers which are listed as:

  • Mbps – small b means megabits per second while B denotes
  • MBps – big B means megabytes per second. The difference is that 8 bits = 1 byte.
  • KBps – kilobytes per second which expresses the uploading and downloading speeds.

USB Slots

USB Slots are like typical Ethernet ports. It is used to hook up an external hard drive to a wireless router. It also connects a printer or all-in-one printer to a wireless router. This allows everyone on the network to print without going to a computer to print.
