How to Boost Wireless Signal – Part 3: Non-Router Network Components

 

Part 1 (free/inexpensive) and Part 2 (other solutions) of “How to Boost Wireless Signal focused on issues associated with the Router.

The third part in this series covers other network components that can improve the strength and range of the wireless signal. This includes the following:

 

Signal Booster (Wi-Fi Amplifier/External Antenna)

  • A Signal Booster attaches to the antenna connector of wireless devices e.g Router, Access Point, Wi-Fi Client/Wireless Adapter and as the name implies, they increase signal strength.
  • These plug and play units are easy to install, increase wireless distance and boost the performance of wireless networks. For example, the Hawking HiGain Signal Booster which has a peak output power around 500 mW (compared to a standard device of around 70 mW) and increases the output power of a wireless signal up to 600%.
  • Although units range in complexity, in general, they function by making the signal flatter i.e. decrease vertical (Elevation) signal but increase the signal horizontally (Azimuth). This results in a stronger signal for users on the same level as the booster, but other users on different floors of the building may experience a weaker signal.

Examples of quality Signal Boosters currently on sale on Amazon are shown below:

GSI Quality High-Powered Secure 1000mW, 2.4GHz, 802.11 b/g/n

As the signal travels farther from the Router it weakens and will eventually lose integrity (Attenuation). Therefore, once the signal strength approaches 25-50%, adding a Wireless Access Point or a Wireless Repeater will be necessary to extend the connection range whilst maintaining signal quality.

Wireless Access Point (AP/WAP/’Hotspot’)

  • A Wireless Access Point will require a power supply and an Ethernet Cat 5 connection to the Router.
  • A major advantage of using an Access Point rather than a Wireless Repeater is that an Access Point does not cut the available bandwidth in half. A Wireless Repeater does this since it has to flip back and forth between transmit/receive with a single signal.

Examples of  boost wireless signal Access Points are shown below:

TP-Link TL-WA801ND 300 Mbps Wireless N Access Point
with 2x 4dBi Antennas

 

Wireless Repeater (Range Expander/Range Extender/Wireless Relay)

  • A Wireless Repeater will pick up the existing signal, rebuild it and retransmit/rebroadcast it at full strength.
  • Its major advantage compared to an Access Point, is that once configured, a Wireless Repeater will only require a power supply and will function as a standalone device that does not require an Ethernet Cat 5 connection to the Router.

Smart Repeater Pro (HAW2R1)

 

Secondary Router as an Access Point or Repeater

Many people choose to use a secondary wireless Router configured to act as an Access Point or a Repeater. The secondary Router connects to the primary Router, and the primary Router connects to the internet Modem.

  • Most newer Routers can operate in Access or Repeater Mode with a simple 1 click operation. For example:
ASUS RT-N12 Wireless-N Router, Access Point, and Repeater

 

  • If the Router is older, then the following procedure can usually be applied:
    • 1- Assign the same SSID and security information from the primary Router to the secondary Router.
    • 2- Turn the secondary Routers DHCP OFF.
    • 3- Connect secondary Routers LAN port to primary Routers Lan port.
    • 4- Assign the same addressing information from the primary Router to the secondary Router. For example:
      primary Router      IP=192.168.2.1  Netmask  255.255.255.0
      secondary Router IP=192.168.2.2  Netmask  255.255.255.0

Wireless Adapter

  • A Wireless Adapter contains an transmitter/receiver that supports certain IEEE 802.11 standards (depending on make/model of Adapter) and allows the device to join a wireless network.
  • Wireless communication is a two-way process e.g. between laptop and the wireless Router, and it is possible for a defective or poor quality Wireless Adapter to cause connectivity issues.
  • Wireless Adapters come in various forms:
    • Most modern Netbooks, Notebooks and Laptops have inbuilt/onboard networking capabilities with a Wireless Adapter ‘equivalent’  built right in to the motherboard. Therefore, they do not require a separate Wireless Adapter and their wireless capabilities are usually of a high standard.
    • USB Wireless Adapter. These provide an easy means to upgrade the networking capabilities of a computer to Wireless-N technology or circumvent a defective onboard network chip in a laptop etc. They are easy to setup (connect to a computers USB port) and can come with an external antenna.
    • PCMCIA/PC Card that slides into a dedicated port on the computer.
    • Desktop computers with PCI bus can have an internal PCI Wireless Adapter.

How to Boost Wireless Signal – Part 2: Other Router Solutions

 

 

Having checked out the free or inexpensive Wi-Fi Router fixes noted in Part 1 of “How to Boost Wireless Signal, it is now time to consider the following options:

 

 

Router Upgrade

Upgrading your Router can bring many advantages and the latest standard is Wireless-N technology (802.11n).

Most Wireless-N Routers advertise Max. Data Rate=300 Mbit/sec which equates to a Net Throughput of approximately 60 MBit/sec

Advantages of Wireless-N Technology

Wireless-N (802.11n) has the following advantages compared to earlier standards:
  • Significantly faster.
  • Better range.
  • More reliable.
  • Less interference issues. Can operate at both 2.4 Ghz and the less frequently used 5 Ghz range.
  • When buying 802.11n equipment you are ‘future proofing’ you purchase.
  • It is backward compatible with the other standards.
  • Secure.
In addition:
  • The stronger coverage (link range) and performance (data throughput) compared with the previous standards comes without requiring additional transmit power.
  • A significantly improved bandwidth is achieved through the use of MIMO technology (Multiple Input, Multiple Output) that allows multiple antennas and signals (up to 4 streams) to be employed. There is a linear relationship with each antenna at each end and throughput, such that:
    • 2 antennas/2 streams  doubles throughput .
    • 3 antennas/ 3 streams  triples throughput.
    • 4 antennas/4 streams  quadruples throughput.
  • Channel Bonding, which allows 2 distinct non-overlapping channels to simultaneously transmit data, produces a significant increase in possible data transmission.

The following lists some examples of quality Wireless-N (802.11n) Routers which are cheapest online through Amazon with the links below:

Gigabit Broadband Router

Cisco-Linksys E4200 Maximum Performance Simultaneous
Dual-Band Wireless-N Router

Belkin N600 Wireless Dual-Band N+ Router (Latest Generation)

 

It should be remembered that in order to get the full benefits of Wireless-N technology, the units within the wireless network need to support the 802.11n standard.

Fortunately, due to the technology being backward compatible, if you were to upgrade and future proof your purchase by buying a Wireless-N unit (e.g. the Router), this unit would communicate perfectly fine with any others in the system that used an older standard (such an 802.11g laptop). In such a case (and given that most people can only afford to upgrade one piece of equipment at a time) the laptop would still be able to operate on the network and access the Internet but would be limited to 802.11g specifications(even though the Router had the ability to operate at 802.11n).

Replace Antenna

Some Routers allow for their antenna to be removed and an upgrade can bring advantages of a stronger signal, greater range and reliability of connection. There are various types of antenna and these include:
  • Omni Directional
    These emit a constant field horizontally but have a vertical directional pattern. Therefore, they work well if situated in the middle of a room but are wasteful when placed in the corner or against a wall. Not only are they needlessly transmitting against/into the wall but possible security issues arise, given that a high percentage of the signal will be transmitted outside of the building.
  • Isoptropic Antenna
    These produce a constant field in both the horizontal and vertical plane.
  • Direction or High Gain
    These focus in one direction, meaning that the signal will be ‘tighter’ and located mostly within the building. This results in a better reception but also reduces security issues associated with a strong signal being broadcast outside of the building. To achieve more gain, a larger/longer antenna and electrical capture area (Aperture) is required. This produces a narrower and more focused beamwidth; such as employed with a Horn Antenna.
  • Multiple Antenna Model (MIMO Technology)
    Wireless-N technology can have up to 4 antennas for superior performance.

Boost Wireless Signal

BoostWirelessSignal.com provides free information, unbiased product reviews, advice, tips and tweaks regarding ways to improve your wireless connection.

Boost Wireless Signal is dedicated to helping you overcome the misery and frustration of having an unreliable wireless connection. This can include having a poor throughput, limited range, dropped connections or even no connections at all!

Wireless technology is commonly termed Wi-Fi. Wi-Fi (Wireless Fidelity) refers to wireless equipment that is used to connect to various devices and the Internet. It is a trademark of the Wi-Fi Alliance and describes a set of standards based on IEEE 802.11.

Although the maximum bandwidth and speed is determined by the package you subscribe to with your broadband provider, one should still aim to get the most out of what you are paying for. Unfortunately, a huge number of people put up grudgingly with an inferior connection and simply blame their provider for a poor service. Although this can be the case, more often than not, an unreliable wireless connection is the result of a poorly set up home network.

Boost Wireless Signal

Boost Wireless Signal

Therefore, the aim is to achieve an optimal wireless signal. What does this mean? Put simply:

  • Boost Wireless Signal strength.
  • Minimize noise by correcting weak, unreliable signals and interference.

“How do I get a stronger wireless signal?” and “How do I increase the wireless range?” are two of the most common networking questions. In order to answer then adequately, it is important to realize that a number of factors may contribute to Wi-Fi problems. The factors and tackling them in a sensible and logical way will greatly increase the chance of achieving a successful outcome. These issues and much more will be covered in various articles on BoostWirelessSignal.com
