Bluetooth Nedir?

WEBVTT 00:00:00.406 --> 00:00:02.708 Was ist Bluetooth und wie wird es verwendet? 00:00:06.589 --> 00:00:13.791 Mit Bluetooth meinen wir ein System, das es Geräten ermöglicht, miteinander zu kommunizieren. 00:00:14.351 --> 00:00:24.174 Der Unterschied zum drahtlosen lokalen Netzwerk besteht darin, dass Bluetooth-Geräte ohne Internet miteinander kommunizieren können. 00:00:26.196 --> 00:00:32.018 Ich möchte Ihnen einige spezifische Informationen über die technischen Kapazitäten und Hintergründe von Bluetooth geben. 00:00:32.138 --> 00:00:36.500 Bluetooth ist eine drahtlose Technik für die Datenübertragung auf kurze Distanz. 00:00:37.500 --> 00:00:40.601 Es ermöglicht mehreren Geräten, ein Netzwerk zu bilden. 00:00:41.001 --> 00:00:46.103 Dadurch können Computer, Zusatzgeräte und Mobiltelefone drahtlos miteinander verbunden werden. 00:00:48.052 --> 00:00:58.298 Mit einigen Gerätetypen ist eine drahtlose Datenübertragung von bis zu 100 Metern möglich, aber die meisten von uns haben Bluetooth-Systeme, die ungefähr 10 Meter erreichen können. 00:00:58.919 --> 00:01:00.080 Funktioniert immer noch. 00:01:03.180 --> 00:01:06.562 Wir haben gesagt, dass die Reichweite bei gängigen Mobiltelefonen 10 Meter beträgt. 00:01:06.622 --> 00:01:09.965 Daher ist der während der Übertragung verwendete Strom recht gering. 00:01:10.605 --> 00:01:19.131 Wenn wir von einem Strom von 100 Metern sprechen, verteilt dieser natürlich eine bestimmte Signalstärke im Raum, und es gibt Untersuchungen, die darauf hinweisen, dass dies ungesund ist. 00:01:19.491 --> 00:01:30.885 Deshalb ist die technische Kapazität von Bluetooth sowohl in Bezug auf den Preis vorteilhaft, sodass es von jedem genutzt werden kann, als auch in Bezug auf die Optimierung einer bestimmten Signallast. 00:01:30.885 --> 00:01:34.208 ist heute auf eine Reichweite von 10 Metern begrenzt. 00:01:37.630 --> 00:01:44.892 Und um Bluetooth zu verwenden, wird natürlich ein kleiner Mikrochip an das Gehäuse eines Geräts angebracht. 00:01:45.133 --> 00:01:47.053 Der Mikrochip hat einen Sender und Empfänger. 00:01:47.113 --> 00:01:49.554 Er kann sowohl Signale senden als auch empfangen. 00:01:50.294 --> 00:01:54.355 Außerdem muss die erforderliche Software zur Verwaltung des Datentransfers auf den Geräten vorhanden sein. 00:01:54.395 --> 00:01:56.075 Sie können es sich wie ein Telefon vorstellen. 00:01:56.115 --> 00:01:58.116 Es kommt Ton rein und unser Ton geht raus. 00:01:59.536 --> 00:02:08.779 Damit Bluetooth-Geräte einander erkennen und andere drahtlose Verbindungen nicht stören, hat jedes Gerät eine eigene 48-Bit-Seriennummer. 00:02:08.999 --> 00:02:18.580 Diese Seriennummer ist eine spezielle Nummer wie unsere Personalausweisnummer und in einem anderen Gerät gibt es keine ähnliche Nummer. 00:02:19.661 --> 00:02:25.282 Die erste Version von Bluetooth konnte maximal 723 kbps Datenübertragung bieten. 00:02:25.322 --> 00:02:26.723 Kilobyte pro Sekunde. 00:02:26.883 --> 00:02:30.124 Diese Geschwindigkeit war ausreichend für kleine Datenübertragungen zwischen wenigen Geräten. 00:02:31.843 --> 00:02:43.038 Aber mit der heutigen Bluetooth-Version 5.2 kann die Datenrate bis zu 2 MB pro Sekunde erreichen und Datenübertragungen können in einem Radius von 400 Metern schneller durchgeführt werden.

WEBVTT 00:00:00.406 --> 00:00:02.708 What is Bluetooth and how is it used? 00:00:06.589 --> 00:00:13.791 Bluetooth is a system that enables devices to communicate with each other. 00:00:14.351 --> 00:00:24.174 The difference from a wireless local area network is that Bluetooth allows devices to communicate with each other without the need for the internet. 00:00:26.196 --> 00:00:32.018 I want to provide you with some specific information about the technical capacity and background of Bluetooth. 00:00:32.138 --> 00:00:36.500 Bluetooth is a wireless technology for short-range data transfer at its core. 00:00:37.500 --> 00:00:40.601 It enables multiple devices to form a network. 00:00:41.001 --> 00:00:46.103 Thus, computers, peripherals, and mobile phones can connect to each other wirelessly. 00:00:48.052 --> 00:00:58.298 With some device types, wireless data transfer is possible up to 100 meters, but for most of us, the Bluetooth system in our hands can still function at around 10 meters. 00:00:58.919 --> 00:01:00.080 We mentioned a distance of 10 meters for commonly used mobile phones. 00:01:03.180 --> 00:01:06.562 Thus, the current used during transfer is minimal. 00:01:06.622 --> 00:01:09.965 If we are talking about a 100-meter current, of course, this current distributes a certain signal power throughout the room, and there are certain studies indicating that this is unhealthy. 00:01:19.491 --> 00:01:30.885 Therefore, Bluetooth's technical capacity is advantageous in terms of price, making it accessible to everyone, and optimizing a certain signal load. 00:01:30.885 --> 00:01:34.208 limited to 10 meters. 00:01:37.630 --> 00:01:44.892 And of course, to use Bluetooth, a small microchip is added to the body of a device. 00:01:45.133 --> 00:01:47.053 The microchip has a transmitter and a receiver. 00:01:47.113 --> 00:01:49.554 It can both send and receive signals. 00:01:50.294 --> 00:01:54.355 Also, the necessary software to manage data transfer must be present in the devices. 00:01:54.395 --> 00:01:56.075 You can think of this as a walkie-talkie. 00:01:56.115 --> 00:01:58.116 Both receiving and transmitting sound. 00:01:59.536 --> 00:02:08.779 For Bluetooth devices to recognize each other and not interfere with other wireless connections, each device has its own 48-bit unique serial number. 00:02:08.999 --> 00:02:18.580 This serial number is a special number like our ID card number, and no similar number exists in another device. 00:02:19.661 --> 00:02:25.282 The first version of Bluetooth could provide a maximum data transfer rate of 723 kbps. 00:02:25.322 --> 00:02:26.723 Kilobyte per second. 00:02:26.883 --> 00:02:30.124 This speed was sufficient for small data transfers between a limited number of devices. 00:02:31.843 --> 00:02:43.038 However, with Bluetooth version 5.2 today, the data rate can reach up to 2 MB per second and data transfers can be done more quickly within a 400-meter range.

WEBVTT 00:00:00.406 --> 00:00:02.708 Bluetooth nedir ve nasıl kullanılır? 00:00:06.589 --> 00:00:13.791 Bluetooth'tan kastettiğimiz şey cihazların birbiriyle haberleşebilmesini sağlayan bir sistemdir. 00:00:14.351 --> 00:00:24.174 Kablosuz yerel alan ağına olan farkı bunun internet olmaksızın Bluetooth cihazların birbiriyle iletişim halinde kalabilmesini sağlar. 00:00:26.196 --> 00:00:32.018 Bluetooth'un teknik kapasitesi ve arka plana hakkında size belirli bilgileri aktarmak istiyorum. 00:00:32.138 --> 00:00:36.500 Bluetooth kısa mesafede veri transferi için kablosuz bir tekniktir temelinde. 00:00:37.500 --> 00:00:40.601 Birkaç cihazın birbirleriyle ağ oluşturmasını sağlar. 00:00:41.001 --> 00:00:46.103 Böylece bilgisayarlar, ek aygıtlar ve cep telefonları kablosuz bir şekilde birbirlerine bağlanabilir. 00:00:48.052 --> 00:00:58.298 Bazı cihaz tipleriyle bu kablosuz veri transferi 100 metreye kadar mümkündür fakat çoğumuzun elindeki bluetooth sistemi aşağı yukarı 10 metre civarında 00:00:58.919 --> 00:01:00.080 fonksiyonunu hala devam ettirebilir. 00:01:03.180 --> 00:01:06.562 Yaygın olarak kullanılan cep telefonlarına mesafe 10 metre demiştik. 00:01:06.622 --> 00:01:09.965 Böylece transfer sırasında kullanılan akım az bir miktarda olur. 00:01:10.605 --> 00:01:19.131 Eğer ki 100 metrelik bir akımdan bahsediyorsak bu akım tabi ki belirli bir sinyal gücünü odaya dağıtır ve bunun sağlıksız olduğuna dair belirli araştırmalar vardır. 00:01:19.491 --> 00:01:30.885 Bu sebeple Bluetooth'un teknik kapasitesi hem fiyat anlamında avantajlı olması yani herkesin kullanabilmesi hem de belirli bir sinyal yükünü optimize etmesi 00:01:30.885 --> 00:01:34.208 için 10 metre ile sınırlı olarak günümüzde kullanılmaktadır. 00:01:37.630 --> 00:01:44.892 Ve bluetooth kullanmak için tabi ki bir cihazın kasasına Küçük bir mikro çip eklenir. 00:01:45.133 --> 00:01:47.053 Mikro çip verici ve alıcıya sahiptir. 00:01:47.113 --> 00:01:49.554 Hem sinyal gönderebilir hem sinyal alabilir. 00:01:50.294 --> 00:01:54.355 Ayrıca cihazlarda veri transferini yöneten gerekli yazılımın da bulunması gerekir. 00:01:54.395 --> 00:01:56.075 Bunu bir telsize benzetebilirsiniz. 00:01:56.115 --> 00:01:58.116 Hem ses geliyor hem sesimiz gidiyor gibi. 00:01:59.536 --> 00:02:08.779 Bluetooth cihazlarının birbirini tanıyabilmesi ve diğer kablosuz bağlantıları bozmamaları için her cihazın kendine ait 48 bit uzunluğunda bir seri numarası vardır. 00:02:08.999 --> 00:02:18.580 Bu seri numarası Nüfus cüzdanı numaramız gibi özel bir numaradır ve başka bir cihazda benzer bir numara bulunmaz. 00:02:19.661 --> 00:02:25.282 Bluetooth'un ilk versiyona en fazla 723 kbps veri transferi sağlayabiliyordu. 00:02:25.322 --> 00:02:26.723 Kilobyte per second. 00:02:26.883 --> 00:02:30.124 Bu hız az sayıda cihaz arasının küçük veri transferi için yeterliydi. 00:02:31.843 --> 00:02:43.038 Ancak günümüzde Bluetooth versiyon 5.2 ile veri oranı 2 MB per seconda kadar ulaşabilmekte ve veri transferleri 400 metre çapta daha çabuk yapılabilmektedir.
