How Does a Wireless Router Antenna Work?

The Antenna Transmits Radio Waves

• Though a wireless router or access point is capable of converting computer and networking data into radio waves, it is not necessarily skilled at accurately transmitting those waves. With no antenna, the wireless access point might be able to transmit the waves only a few feet, while an antenna enables transmission over a much greater distance. This transmission capability is achieved by sending electronic signals to the antenna, causing its internal electrons to oscillate. These oscillations are broadcast by the antenna, and the length of the antenna helps focus the broadcast in the 2.4GHz to 5GHz frequency range commonly used by Wi-Fi networks

The Antenna Receives Radio Waves

• Just as the antenna's electrons oscillate while transmitting data, incoming radio waves cause a second set of electrons (usually located in the second antenna of a wireless router, or a secondary set in a single antenna configuration) to oscillate. The movement of these receiving electrons generates an electronic impulse that can be picked up by the wireless access point's processing system

The Wireless Router Antenna Works in All Directions

• Some types of antennas, like satellite transmitters and surveillance equipment, only transmit or receive in one direction. Other antenna configurations, such as those found on television and Wi-Fi equipment, transmit and receive in all directions to provide the maximum possible coverage. In addition, the length of the antenna attached to a wireless router is significant, as the antenna is designed to be only slightly longer than the wavelength of the transmissions it sends and receives. Radio engineers have determined this length to be optimal for Wi-Fi usage, while longer antennas may be better suited for citizens band (CB) or amateur radio usage

About Wireless Router Antennas:

• A wireless router is a device that transfers data packets between networks. In the simplest term, a wireless router helps individuals access the Internet without the use of wires. We are living in the wireless technology age and consumers are looking for flexibility and convenience along with security. Wireless routers offer this, plus so much more.

Connection

• A wireless network can either connect a LAN (Local Area Network) or a WAN (Wide Area Network). A LAN is the type of network that can be found in your home or a small office, while a WAN is used on a much larger scale. The router plays the role of a bridge between a modem or computer and the network. Using an Ethernet cable, the router connects to the main computer or server. Built-in functionality for access points allows the router to send and receive data packets to other computers connected to the network without the use of wires

Why Wireless Routers

• Wireless routers have the same benefits as wired ones in terms of connection speeds and reliability. Wireless routers also terminate the clutter associated with connecting multiple computers with cables and wires. There is also the added benefit of not being tied down by wires and the ability to move freely around the home. Another benefit is IP address sharing. Every computer on the network can share the same IP address and cut out the need to have separate ISP (internet service provider) accounts with each computer. The increase in network performance, manageability and security are just some more great reasons to use a wireless router

Security

• Wireless routers can make a network more secure or it can leave it wide open for attackers. The security problems mainly come from user error and their failure to assign a WEP (wired equivalent privacy) key to the wireless account. WEP provides encryption to the network so that outside forces don't have access to files being transferred over a wireless router. Without the WEP being enabled, anyone within distance of the wireless connection area can access any computer on the network using any type of Wi-Fi device.
• Many critics think that WEP is not as secure as it should be and is easily compromised. New developers and manufacturers of wireless router technology are constantly looking into ways to make the devices more secure

Protocols

• The two protocols implemented by wireless routers are NAT (Network Address Translation) and DHCP (Dynamic Host Configuration Protocol). The NAT protocol is responsible for enabling multiple devices on the network to share the same IP address. The DHCP allows for new devices to be added to the network with very little or no additional configuration needed to be made by the user or network administrator

Cable vs. DSL

• The type of wireless router that you require depends on the type of service you currently have. Most service providers equip their customers with a wireless router for additional costs. The big debate comes from what service is better to have. DSL service is offered by the phone company and receives a connection generally through the phone lines. A cable router is used for Internet service provided by a cable or satellite company. Cable is generally known for faster speeds than DSL, but is less reliable. DSL is more consistent with its speed, offering the same upload and download speeds on a daily basis. Both types offer the same in security and popularity, yet some customers seem to be more satisfied with the DSL service than they are with cable
