何謂 Android OTA (13-08-20更新文章)
想必很多人都聽過OTA但也許有些人並不是真的很了解這是什麼
OTA其實就是指 使用手機網路/手機WiFi 更新Android系統的服務
當Android有新的版本的時候不需要連接電腦就可以更新了(但手機必需要是連上網路的狀態!)
所以我的Android手機如果系統有新的版本的時候就可以OTA更新了嗎?
答案是不一定
要看你是那一支手機
有一些手機硬體場商不提供OTA服務
OTA來源也會因為手機硬體場商的不同而有所不同
如果你是用Google手機的話你的OTA來源一定是Google
所以如果你的OTA來源是Google更新一定是最快取得最新版本的
也就是說如果今天Android有了新的版本4.1時
你可以很快的就更新上去但別人的手機可能都還在等4.0的更新
因為除了Google手機外的手機OTA來源都是該手機的硬體場商
這就是使用Google手機的優點
新版本取得速度快
系統是原生的效能也最優速度也快
那其他手機場商的OTA為什麼這麼慢才能得到更新呢?
為何Google自已的手機都可以這麼快就更新上去但其他的就不能呢?
因為手機場商怎麼可能只出一支Android手機
一定是很多支
但偏偏每支手機的規格又不同
規格不同對系統核心的調整就不同
所以每支手機如果都需要OTA更新的話
手機場商必需要對每支手機都做新版本的測試和調整
之後才能OTA更新
也就變成通常很低階的手機都是不能OTA更新
又或是可以但從來沒有更新
不過這樣的手機通常都沒有鎖機可以讓你自行的刷機
這樣聽起來其實也沒有那一種選擇是最好的
完全是看個人的使用偏好
我本身是偏好我希望有新的Android版本出來的時候我就可以速速使用到
不需要等太久
所以我只用Google自已的手機
但如果我不是這樣的一個新版本偏好的使用者
我只希望我的手機能達到我的使用目的
那我就只需要去選擇一支適合我的手機
再者就是如果我是一個超愛刷機
喜歡試試不同的ROM的使用者
那當然就買支便宜硬體不差的無鎖手機拿來刷來玩就可以了!!
(大部分高規格手機都是鎖ROM版本 不隨意讓您刷機的)
OTA?!不會這麼奇怪或是不解了吧!?
目前來源是Google的OTA手機只有以下幾支
Nexus One(HTC代工) 目前已經達到硬體無法支援的狀態不會再更新到新的Android版本了!!
Nexus S(Samsung代工)
Galaxy Nexus (Samsung代工)
Nexus 7 (ASUS代工)
Nexus 7二代 (ASUS代工)
Nexus 4 (LG代工)
Nexus 10 (Samsung代工)
HTC NewOne 原生版 (Google Play上才買得到)
Samsung S4 原生版 (Google Play上才買得到)
Galaxy Nexus台灣版早期有更新比Google自售美版慢得問題
現在已經沒有了
Nexus 7也沒有這個問題了
現在可以確定的是Nexus系列的產品都是Google自己維護更新
http://en.wikipedia.org/wiki/Over-the-air_programming
Over-the-air programming (OTA) refers to various methods of distributing new software updates, configuration settings, and even updating encryption keys to devices like cellphones, set-top boxes or secure voice communication Equipment (Encrypted 2-Way Radios). One important feature of OTA is that one central location can send an Update to all the Users; who are unable to refuse, defeat, or alter that Update, and it applies immediately to everyone on the Channel. A User could "refuse" OTA but the "Channel Manager" could also kick them off the Channel (automatically).
In the context of the mobile content world these include Over-the-air service provisioning (OTASP), Over-the-air provisioning (OTAP) or Over-the-air parameter administration (OTAPA), or provisioning handsets with the necessary settings with which to access services such as WAP or MMS. On modern mobile devices such as smartphones, an Over-the-air update may refer simply to a software update that is distributed over Wi-Fi or mobile broadband using a function built into the operating system, with the "Over-the-air" aspect referring to its use of wireless internet instead of requiring the user to connect the device to a computer via USB to perform the update.
As mobile phones accumulate new applications and become more advanced, OTA configuration has become increasingly important as new updates and services come on stream. OTA via SMS optimises the configuration data updates in SIM cards and handsets and enables the distribution of new software updates to mobile phones or provisioning handsets with the necessary settings with which to access services such as WAP or MMS. OTA messaging provides remote control of mobile phones for service and subscription activation, personalization and programming of a new service for mobile operators and telco third parties.[1]
Various standardization bodies were established to help develop, oversee, and manage OTA. One of them is the Open Mobile Alliance (OMA).
More recently, with the new concepts of Wireless Sensor Networks and the Internet of Things, where the networks consist of hundreds or thousands of nodes, OTA is taken to a new direction: for the first time OTA is applied using unlicensed frequency bands (2.4 GHz, 868 MHz, 900 MHz) and with low consumption and low data rate transmission using protocols such as 802.15.4 and ZigBee.[2]
Motes are often located in places that are either remote or difficult to access. As an example, Libelium has implemented a smart and easy-to-use OTA programming system for ZigBee WSN devices. This system enables firmware upgrades without the need of physical access, saving time and money if the nodes must be re-programmed.[3]
