This document provides tips on troubleshooting Wi-Fi interference in 3 steps: identifying potential sources of interference; optimizing the location and settings of the Wi-Fi modem; and testing wireless performance to identify the best channel. It recommends placing the modem high and centralized, avoiding crowded wireless channels, and using the modem's graphic user interface to change settings like the radio channel. Performance should be tested after making changes to determine if connection speed and reliability improve.

When choosing a new Wi-Fi router, you should consider the Wi-Fi standard, range, and features that affect throughput. Newer standards like 802.11ax (Wi-Fi 6) provide faster speeds. Built-in technologies such as MU-MIMO, Beamforming, and OFDMA can increase speeds by allowing simultaneous connections from multiple devices. Gigabit Ethernet ports and dual-band 2.4GHz and 5GHz Wi-Fi bands ensure maximum performance for a variety of devices and tasks. Evaluating these factors will help you select a router suited to your needs and environment.
Types of Internet Connections - R.D.sivakumar
This document discusses various types of internet connections including dial-up, ADSL, cable, leased lines, Wi-Fi, WiMAX, satellite, mobile phones, power line communications, and fiber optics. It provides details on how each type of connection works and its key characteristics.
Internet connection
The document discusses different types of internet connections including wireless, Wi-Fi, satellite, cable, dial-up, and DSL. Wireless internet uses radio frequencies to provide an always-on connection anywhere within range, typically in metropolitan areas. Wi-Fi allows devices to connect to wireless networks within 100 meters. Satellite internet connects to orbiting satellites and averages 492-512 Kbps speeds. Cable internet operates over existing cable TV lines and ranges from 512 Kbps to 20 Mbps with more range than other options. Dial-up uses telephone lines and is slow while blocking calls. DSL is always on and ranges from 128kbps to 8 mbps.

Types of internet connections
The document discusses various types of internet connections including analogue/dial-up, cable, satellite, DSL, and Internet2. Analogue/dial-up is the slowest and uses a modem to connect via phone lines. Cable uses coaxial cables for faster transmission than phone lines. Satellite provides connectivity anywhere but is slower than broadband due to distance. DSL uses phone lines for an always-on connection and comes in varieties like ADSL. Internet2 has extremely high speeds up to 100Gbps but is uncommon.
Wi max
WiMAX (Worldwide Interoperability for Microwave Access) is a wireless technology that can provide broadband connections over long distances. It uses frequencies between 2-11 GHz and 10-66 GHz to transmit data at speeds up to 70 megabits per second for distances of up to 30 miles. WiMAX has advantages over traditional broadband including broader coverage, higher speeds, lower costs, and the ability to access the internet remotely without cables. However, it also has disadvantages like being impacted by power outages, weather conditions, and potential interference from other wireless devices. WiMAX can support applications like video streaming, VoIP calls, video conferencing, and e-learning by providing a fast, wireless alternative to cable broadband networks.
Different broadband options available to the stillorgan area
The document discusses broadband internet options available in the Stillorgan area, including WiMax, Digiweb, UPC, Eircom, and Vodafone.

What is Wi-Fi?
Wi-Fi (Wireless Fidelity) is a generic term that refers to the IEEE 802.11 communications standard for Wireless Local Area Networks (WLANs).
Wireless Technology is an alternative to Wired Technology, which is commonly used, for connecting devices in wireless using radio waves.
Allows you to access the Internet while on the move ; you can remain online while moving from one area to another, without a disconnection or loss in coverage
IEEE 802.11 Standard
In 1997, the Institute of Electrical and Electronic Engineers (IEEE) drafted the 802.11 standard for wireless local area networking.
In 1999, networking hardware companies accepted the standard and began manufacturing products using the 802.11b protocol which operated in the 2.4 GHz range and was capable of transmitting at speeds of 11 Mbps.
The 802.11a protocol was also released in 1999, operating at 5 GHz with transmissions speeds of 54 Mbps, but its cost was high.
What is a Hotspot ?
A Hotspot is any location where Wi-Fi network access is made publicly available.
Hotspots are equipped with a Broadband Internet connection, and one or more Access Points that allow users to access the Internet wirelessly.
Hotspots can be setup in any public location that can support an Internet connection.
How a Wi-Fi network works?
A Wi-Fi connection works
through a transmitting antenna,
which is usually connected to a
DSL or cable Internet connection.
The antenna on the router will
then beam radio signals through
a specific range. Another antenna,
which is on the laptop or personal
computer, receives the signal.
Internet connectivity
This document discusses various types of internet connectivity options. It describes gateway access, dial-up connections, leased connections, DSL, cable modem connections, VSAT, and wireless/satellite internet connections. For each type, it provides details on the technology, speeds, advantages, and disadvantages. The main points are that there are different levels of access from limited gateway access to dedicated leased lines, and that connection speeds and capabilities have increased significantly over the past 10-20 years with technology improvements like DSL, cable, and wireless/satellite options now available.

It also covers applications of Wi-Fi in homes, businesses, and for travelers, as well as limitations like interference and advantages such as mobility and flexibility.
EnGenius Europe - Sales presentation ESR-series
The document discusses EnGenius wireless routers for small businesses and homes. It provides details on 5 router models - ESR300, ESR350, ESR600, ESR900, and ESR1750. The routers offer wireless speeds from 300Mbps up to 1300+450Mbps, have 1-3 internal antennas, and include features like storage sharing, parental controls, and guest networks. They are targeted towards providing fast and secure wireless connectivity for homes, SOHOs, and small offices.
What is Broadband Antenna Tracking?
Broadband Antenna Tracking allows antennas to auto-align as ships or vehicles move, maintaining a wireless broadband connection between moving objects like oil rigs and support ships, ferries and land, or land vehicles and control bases. Distances and speeds supported are similar to stationary point-to-point and multipoint wireless, with tracking emulating a stationary connection during movement over distances up to 50km at speeds up to 2Gbps for point-to-point, and up to 5km at 100Mbps per sector for point-to-multipoint wireless.
Wimax
WiMAX is a wireless technology that provides broadband connections over long distances. It can provide internet access to homes and businesses in a radius of up to 30 miles from the base station. WiMAX connections operate at speeds up to 70 megabits per second without needing direct line-of-sight to the base station. It uses frequencies between 2-11 GHz and 10-66 GHz and defines both MAC and PHY layers. WiMAX can be used for last mile broadband access, wireless backup connections, and providing mobile internet access across wide areas. While it has a high data rate and long range, WiMAX speeds are reduced at maximum range similar to other wireless technologies.
