As the quality of VoIP calls can improve

In these days when you're just starting a home or small office, the chances that you also consider VoIP providers, rather than proposing a different phone line, but the analog VoIP call quality and reliability depends on a number of factors off. Here are some suggestions for improving the quality of VoIP calls.

There is a glossary at the end of this article.

Choose the right combination

If you use an IP phone or analog telephone adapter, make sure you choose a with proven experience. There are so many manufacturers and new entrants to the market each month can be a difficult task to remove the bullet. Many manufacturers ship their new handsets with pre-release firmware, can give rise to within a range of topics, ranging from the difficulties in configuration, to, and calls sound choppy. A Web site is for the monitoring of good advice for users of mobile phones and ATA's community site provides a wealth of information about VoIP in general.

Select the codec

A codec (short for encoder / decoder) is the software algorithm is used to convert analog audio to a speech (usually compressed) in digital form. There are a number of codecs for VoIP. Most ATA devices and at least two.

In general, the compromise in the choice of a codec between the bandwidth and CPU utilization. The codec is the bandwidth costs usually requires little CPU power. Select the codec that is used depends on you, especially if you are) to a telephone system to connect your local network (usually the case in large offices, or, as so often come with a small office or home, in touch to a virtual PBX provider or Internet telephony, broadband services. If you are connected to the network bandwidth limitations, so you must choose a full-rate codec such as G711. When you connect to the Internet, but you obviously need to have some compression. In this case, a codec such as G729 or iLBC give good results.

Since the Internet is an open network uncontrolled, travel information about them is often a path deviations disorderly increases. Data packets do not often come in order, and with various delays (VoIP jargon jitter). Some much better than other codecs with jitter, for example, G729 is particularly resistant to jitter. In some cases, the packets are lost. Virtually all VoIP codecs react badly to the loss of packets.

If you have a large compression codec, which necessarily requires more CPU power, it is important to ensure that they are) installed on a robust phone with the latest firmware to see (note above regarding the choice of connection. Badly written firmware often causes disturbed audio compression with a high level because the CPU is not easy to cope with the requirements of the algorithm.

Prioritization of Internet traffic

Select a good unit and the codec is the most appropriate of no use when VoIP calls are to compete with other Internet traffic on your broadband connection. It could be a perfect crystal with a customer when they suddenly interrupted by all sorts of distortions and dropouts, because the computer is busy downloading several megabytes of e-mail.

Most SOHO routers have a modern system of priorities for different types of traffic competing for the use of the connection. The simplest form of giving more importance, the visitors destined to a specific IP address and port number or range. You need the IP address and UDP port to define the field for your audio VoIP providers (they will be able to) make this information available. Another simple form of hierarchy and internal IP address - but this requires that your phone a static IP address (rather than automatically assigned to a library) of your router.

Some modern routers are intelligent enough to recognize VoIP traffic and prioritize that traffic than others. In fact, some manufacturers are now made with cheap equipment between the router and broadband modem connection to connect. These devices require no installation and commissioning automatically prioritize voice traffic.

However, other routers offer, which is such as QoS (Quality of Service) known. These are special tags that the IP packets to read from some ISP routers and are used in order to prioritize the traffic within the ISP network to be assigned (even left a broadband modem). Most ISPs also provide broadband telephony services are a kind of QoS support. It is best to consult the technical service for ISPs exactly how. While valuable, QoS will not help if you have already paid for the priority of the internal data traffic with the methods described above.

What You Need To Know About The Wireless Router For Laptops?

So how can you set up your internet connection so it has a wireless router for laptops to connect to?

First, in case you don't know, a wireless router is the piece of equipment that makes wireless technology possible.

When you attach your cable or dsl modem to a router, it allows any computer with a wireless network card to connect to the internet.

What should I look for when purchasing a router?

First, you want a router that has at least 802.11g technology.

If you look at the description and it doesn't say anything about having 802.11g then don't purchase it. Do not get a router that is just 802.11a or 802.11b.

Caveat There is new router technology that will be out soon called 802.11n. If you want to connect at incredibly fast speeds then purchase this instead.

What Else Should You Consider?

Think about how many people will be using your wireless connection at one time.

Routers vary on how many computers they allow to be connected at one time. If you expect several people to be connected at once, purchase a router that will be able to handle many laptop computers at the same time.

Also, consider who will be using the internet through your router. If you live in a congested area, it is very likely someone will try to get internet access through your router.

Be extremely aware of this!

Endless possibilities can happen when the wrong person is using your internet access. So do the best thing and prevent it from happening.


Try to find a router that offers quality security. And more importantly, a router that lets you have your connection password protected.

It is strongly encouraged that you set it up to where you have to enter a password to connect.

Even if you aren't worried about security, having many unknown users using your internet will make your internet connection painfully slow.

How to increase your wireless router signal

There are many ways that can increase your wireless router signal. Here is recommended methods to increase wireless router signal effectively.

- Install an Amplifier

Install wireless amplifier or booster to your router can help to boost . A booster can be more affordable than a repeater as they only increase the strength of your existing signal, rather than the range . Use a bi directional amplifier to increase outbound & inbound speed.

- Change to different signal channel

Routers can broadcast on many channels from 1 to 11. Change to a channel that will allow your router a better signal between other wireless devices.

- Check for interference

Move devices in your home that can interfere with network traffic on the 2.4GHz frequency range. These devices include many cordless phones, microwave ovens, and the like.
Check your signal strength with these devices on and off to determine if they are the cause of your signal problems.

- Raise your transmit power

Some wireless router has configuration utility for the ability to change the Xmit power of your router: the amount of power it uses to transmit the signal. generally you can boost this number by up to 50mW. Beware of risk overheating or damaging your router.

- Replace the Antenna

Unscrew and replace the broadcast antenna on your router with a model that delivers more power. Not all routers allow for new antenna to be attached, but many do.

- Install a Repeater

A repeater is a network device that acts like a wireless network extender. The repeater takes the signal from your router and boosts it to increase the range. Wireless repeaters are increasingly common and affordable and will probably be available in your local computer store, or on the Internet.

- Reposition your Router

Lift up your wireless router as far as possible to increase the effective broadcast range. Place near the center of your house or apartment for wider coverage. Move closer to the receivers, if possible. Move away from any metal including metal shelving, filing cabinets and similar common objects. Move away from cordless phones and microwaves, which operate on the same 2.4-Ghz frequency. Move away as far as possible from your neighbor's Wi-Fi router (which, of course, you should also make sure you're using a different channel)



Combine all method to the most effective to increase your wireless router signal.

Common Security Setup for Wireless Router Guide

Security setup for wireless router is very important because wireless signal is emitted in public that anyone near your wireless router that have wireless device can sense your wireless signal. When manufacturers ship wireless routers, all security is disabled. If you do not process to setup security for your router, people that you're invited to network will be access your network openly.

It is very easy to setup security for your wireless router. Below is the common process for setup your wireless network security.

- Change the default SSID

The SSID is the name that Identify wireless device. All wireless devices on a WLAN use SSIDs to communicate with each other devices. Routers ship with standard default SSIDs. There is default SSID for each routers, such as EDUP, LINKSYS, DLINK, etc. If you don’t change the default SSID of your router a hacker will attacked known type router by common SSIDs from major manufacturers easier.


- Password protection

Commonly open internet browser and enter URL to access setup. The URL will be specified in the router manual. The URL (http://xxxxx) for access routers are http://192.168.0.1 or http://192.168.1.1.

- Disable SSID broadcasting

Wireless enabled computers use network discovery software to automatically search for nearby SSIDs. Some of the more advanced software will query the SSIDs of nearby networks and even display their names. Therefore
changing the network name only helps partially to secure your network. To prevent your network name from being discovered
you must disable SSID broadcast. After that , you will have to configure your computers to connect to your wireless network using the new name.

- Restrict devices that can connect to the router by filtering out MAC addresses

- Use Encryption connection such as WEP and WPA

The most of home uses the WEP/WPA encryption is enough security.

How to choose new router?

A modern wireless router specifications for present is 802.11n, 4 Ethernet ports, Hi-speed Boardband WAN port. It cost around 50$. Even low cost router supports 802.11n, although they don't have as many features and doesn't have a built-in modem, so you'll have to use it with a modem that has an Ethernet port. Also available at this price are 150 Mb per sec routers. These have fewer antennas, but are often as fast as 802.11n devices. You can expect a transfer speed of around 30 Mb per sec at 10m from any modern 802.11n router.

If you have ADSL, you should get a wireless router with a built in modem. It will cost more than the equivalent cable router, but it lets you connect your router directly to your broadband connection without a separate modem. ADSL 2 plus modems support broadband connections up to 24 Mb per sec with an ISP.

Many routers have built in USB ports that allow you to connect a USB drive and use the router as a basic network storage device. If you want to share a USB printer on your network, look for a wireless router with a built in print server. Alternatively, you can add a dedicated wireless print server later. Finally, if you're interested in making voice calls over the internet, look for a router with built in Voice Over IP support as this can save you money.

Most 802.11n wireless routers use the 2.4GHz frequency. This has good range but can be prone to interference if it's near a lot of other 2.4GHz devices, such as other routers and baby monitors. If you have trouble getting a consistent wireless signal or you want faster transfer speeds for wireless video streaming, it's worth buying a dual-band router, which can use both the 2.4GHz and 5GHz bands. Alternatively, a hi-gain antenna can boost signals and improve ranges and throughputs to the whole house. You can also add a hi-gain antenna to a PC's network adaptor. If wired network speeds are a priority, look for a router with Gigabit Ethernet.
