What is Bluetooth®?
Bluetooth® is a license-free short range radio technology in the 2.4 GHz band (radio frequency). It was originally developed for medical and industrial purposes. Besides hands-free speaking systems and PC synchronization, Bluetooth® today is also used for content transmission. The reach of mobile phones is usually 10 meters - the transmission range of the Hiwave Bluetooth® Hotspots can be adjusted from just a few meters to up to about 30 meters.

 

 

How many mobile phones are equipped with Bluetooth?
More than 80% of all mobile end devices circulating the German market have Bluetooth®.

 

 

What are the most frequently sold devices?
Manufacturers hardly ever publish figures containing such information. The following lists compiled by the specialist portals inside-handy.de and connect.de show an overview of the mobile phones currently in highest demand.

 

 

How do the contents get into my mobile phone?
Just turn Bluetooth® on, set to visible and allow the reception of content. Depending on the configuration of the hotspot, the mobile phone may have to be held close (<30cm) to a download point prior to reception. Blackberry users must type a PIN (usually 0000) to receive content.

 

 

On which mobile phones Bluetooth downloads do not work?
With Apple iPhone, and Nokia 6310/6310i you can not receive files via Bluetooth. With Samsung devices, sounds und videos can be received, but neither games nor other applications can be installed.

 

 

I don't want to receive anything via Bluetooth. What do I have to do?
Just deactivate Bluetooth® or set it to "invisible". Headsets can then still be connected to the mobile phone if Bluetooth® is set to "invisible". When closing, the headset has to be paired, after which Bluetooth® can be set to "invisible".

 

 

How fast is file transfer via Bluetooth on my mobile phone?
Bluetooth® (versions 1.x) is about as fast as DSL 1000, i.e. up to 90kb/sec. transfer rate. The actual speed depends on the file size but also the environment (obstacles, other radio sources) and the distance to the transmitter. Under realistic conditions, transmission of a file under 100 kb max. 3 seconds; a file up to 500 kb up to 20 seconds; up to 1 MB up to 40 seconds; 2.5 MB over 1 minute. Transmission is three times as fast with Bluetooth® 2.0+EDR. The following versions will achieve much higher data rates (Ultra Wideband, between 30 and 160 times quicker than Bluetooth 2.0).

 

 

Where does my end device store the content?
That depends on the type of content and the manufacturer. Simple content is usually stored in the incoming mailbox (new messages) or under "Pictures". Text and HTML files, depending on manufacturer, are usually saved in the folder "websites" or "miscellaneous".

 

 

Isn't Bluetooth® insecure?
Quite the contrary. Bluetooth® data circuits have security relevant data through a secure 128 bit encryption, further a frequency hopping procedure with 1,600 frequency hops per second is used. Although some reports from the media may have given the impression that the transmission route Bluetooth® is insecure, it was actually due to the Bluetooth® implementation of individual, often older devices that have led to security gaps.
Even Bluetooth security specialist such as the trifinite group state that Bluetooth® is "per se a secure standard". The trade press reports: "Up to now, warnings concerning viruses on mobile devices have exclusively come from software manufacturers [of anti-virus software]; no user has ever complained of such attacks" (quoted from ComputerPartner d.d 23.1.2006). The Spiegel writes (12.2.2006): "Even with an activated Bluetooth® connection, infection has previously only been possible with the aid of the mobile phone owner. (...) The user of the target phone must agree before a file can be loaded. Then the virus attempts to install itself on the mobile phone, which can only be done once the user confirms this. Viruses MMS [via GSM mobile network] however can enter the mobile phone without any assistance by the user. (...) The precautionary approach practically rules out a virus infection on a mobile phone device.
The Federal Security Office for Information Technology writes: "These attacks do not originate from any weaknesses in the Bluetooth Standard but through faulty implementation of the standard on the part of the device manufacturer." The trade publication c't recommends switching Bluetooth off if one is not certain from whom a request is coming.
In this context, Hiwave offers various pull-download variants to provide the user with additional security.
