Types of Bluetooth Speakers

Bluetooth speakers, also known as parlantes Bluetooth in Spanish, usually come in two different types. Passive speakers are powered completely by an external amplifier and are most often used in larger venues. Active speakers feature an on-board amplifier and power supply, making them portable, but also capable of providing custom, tailored sound settings and audio processing features.

Depending on your listening needs and environment, one of the two types can best suit your indoor or outdoor demands. Both varieties offer optimal sound quality within their recommended signal range, but if you’re looking to extend that further during larger events or open-air locations, then you’ll want to consider additional equipment such as Bluetooth extenders (commonly called repeaters) to effectively extend signal range without sacrificing audio quality.

Factors Affecting Bluetooth Range

When it comes to extending the range, it’s important to know the different factors that can affect the reach of your signal. Knowing these factors and taking steps to address them can help you avoid audio breaks and drop-outs as well as improve sound quality.

Distance

Distance can have a major impact on the range and this is largely determined by the type of Bluetooth device you are using. Class-1 Bluetooth devices have a maximum specified range of 100 meters while class-2 typically reach a maximum of 10 meters. The antennas inside each device will also have an influence when it comes to distance, as well as any obstacles such as walls, furniture and even people that stand between you and your speaker/headset.

Bandwidth

The type of bandwidth allocated for each packet being sent between two devices also has an impact on how far these packets reach before they start degrading with increased distance. For audio, high bitrate codecs (i.e., SBC codec with 128 kbps or even 48 kbps) require higher ranges compared with narrow band codecs (i.e., narrow or lower bitrate such as 11 kbps).

Frequency Hopping Spread Spectrum (FHSS)

FHSS is a technology used in some wireless basebands which makes it possible for transmitters to move (hop) their signal across multiple frequency points in a band instead of sending all signals at one frequency point only. This helps avoid interference caused by many wireless signals operating at the same frequency within range, thus improving communication reliability in wireless networks including Bluetooth headsets/speakers over extended distances or with obstacles blocking its path.

Simple Tips to Boost Bluetooth Signal Range

Bluetooth is a great technology for wirelessly connecting devices. The signal can be improved by making simple tweaks to the environment without changing your speakers. By following a few basic tips, you can increase the range of them and enjoy the highest quality sound possible.

– Move Devices Closer: One of the simplest things you can do to improve range is place the device sending and receiving signals closer together. Placing devices within five feet of each other will guarantee maximum signal strength and optimal performance.

– Use Accessories: If physically moving your devices closer is not an option, there are accessories that can help boost signal strength. A coaxial coupler works like an amplifier and extends up to 100 meters in length, allowing you to move farther away from the source device while still receiving clear audio signals.

– Create a Clear Line of Sight: Make sure that there are no objects in between your speaker and receiver unit – Walls, furniture, even people act as blockages for signals so it’s important that they are eliminated when possible. Many speakers come with built-in stands, so take advantage of them if available!

– Setup Stationary Connections: Avoid attempting to move the speaker or receiver while connected as this can degrade signal strength due to long distances traveled or large physical barriers encountered along the way. Instead opt for stationary setups where both devices remain in one location at all times during use – this ensures consistent performance regardless of location changes later on down the road!

Advanced Tips to Boost Bluetooth Signal Range

Most of this type of signal ranges are limited to about 33 feet (10 meters). This range can, however, be extended or boosted with a few advanced tips and tricks.

One way is to use a dedicated antenna or extender. These are usually powered products, such as a small USB dongle that is inserted into the base of the speaker’s Bluetooth unit and placed in an area with clear line-of-sight of your other devices. The dongle will then amplify the signal, extending its reach to up to 100+ feet.

You can also connect two devices together via Bluetooth and have them “handshake” or send audio through each other, thus amplifying the signal strength. The primary device (such as your laptop) should be set up as the “master” and connected to a secondary device (such as an amplifier or speaker) which will then receive music from it instead of directly from your mobile device.

Another tip is to move around your home while streaming music from your wireless device in order to determine which locations provide optimal signal strength for your speaker.

Avoid placing any barriers between your speakers and streaming devices and opt for wireless mesh networks over wireless networks when available; this helps reduce signal interference from other wireless signals in your area. Additionally, making sure all antennas are pointing as directly towards each other as possible can help boost their connection strength beyond normal levels.

Conclusion

In conclusion, there are a variety of ways to boost or extend your Bluetooth speaker signal range. These methods will help you get more out of your existing speaker system and enjoy music without interruptions. When selecting a range extender, always consider the distance you want to improve and the strength of the signal it needs to transmit.

A stronger signal will require more power and can be an expensive solution. You should also take into consideration the quality of the range extender itself. After considering these points, look for an affordable and quality range extender that can meet your needs best. You may also want to consider using a wireless adapter connected to your computer in order to get better streaming performance from certain applications such as Netflix or Hulu Plus. With these solutions, you’re sure to find improved audio performance with only minimal investment!

In this post we will show you, how you can change the default SSH port from the world known 22 to something else.

Note: Having your SSH running on port 22 does not mean that you are running a insecure system, this tip only makes it a bit harder to guess on which port SSH is accessible from.

To change your default SSH port from 22 to something else you will need to have root access (you can read our earlier article on disabling direct root access and claiming it for any user) before you make any of the changes.

Once you have root access open the file /etc/ssh/sshd_config and search for Port, it should show 22 as the default value. Change 22 to any port you want that is not already being used on the system.

Once you have made the change to use a different port, save the file and issue the command /etc/init.d/ssh reload. That’s it your default SSH port should be disabled now, you will need to setup your SSH clients to reflect the changes, or else you may see Permission Deniederrors.

While logging in from another server, instead of typing ssh servernametype in ssh p portnumber servername, replace the portnumber with the port number you setup in the earlier steps.

If you are using putty just change the default port from 22 to your new port and save the settings.

Installation

Before we get to how to use it, here is how to install Deja Dup in Ubuntu. Deja Dup is in the Ubuntu main repository. So to install it, open the Terminal and execute the command,

$ sudo apt-get install deja-dup

After the installation, you can find Deja Dup using the Dash in Ubuntu 11.04. If you are using an earlier version of Ubuntu or the Classic Desktop in Ubuntu 11.04, you will find Deja Dup under Applications > System Tools.

Backing up files

Before you start using Deja Dup, you need to set it up first. Run the application Deja Dup Backup Preferences. Under the tab, Storage, you have to specify the backup location. Deja Dup supports backup to local folder, Amazon S3, Rackspace Cloud, FTP, SSH, WebDAV and Windows Share. Pick the backup location – most of the users will backup to local folder. For added security, it is recommended that you check the box next to Encrypt backup files.

If you pick Local Folder, select the folder where you want to store the backups. It is recommended that you select a folder on a different hard disk from the one you are taking the the backup. Also note that the backup files might require a large memory. So, make sure there is enough space available in the backup folder.

Now that we have set up the backup location, we need to select the folders we want to back up of. To do that, click on the next tab, Files. There are two fields – Include files in folders and Except files in folder. In the first field, you can select the folders of which you want to take back up of. Deja Dup will take backups of all the files inside the folder and those in the sub folders. The second field can be used to exclude sub-folders inside the folders included in the first field from being backed up.

The next step is to decide if you want to do either a manual backup or an automatic backup. Choosing automatic backup means that you have to schedule the backup and select how long Deja Dup holds on to the backup files. For those details and how to restore the files, read the second part of this coming up soon.
