[技术课程] ROM这些事_参数详解(一)
在/system下的文件里,我们常看见以下语句。
ry = 10
ry = 6
= 2
nd=1
cant_scan_interval=45
ze=24m
= 2
这几行主要是设置网络数据、定位、语音、内存等方面的优化。
======================================================
根据上面的参数代码,下面列出不同数值对应代表的意义
ry :
1 = 1.2 Mbit/s
2 = 1.2 Mbit/s
3 = 1.8 Mbit/s
4 = 1.8 Mbit/s
5 = 3.6 Mbit/s
6 = 3.6 Mbit/s
7 = 7.2 Mbit/s
8 = 7.2 Mbit/s
9 = 10.1 Mbit/s
10 = 14.0 Mbit/s
11 = 0.9 Mbit/s
12 = 1.8 Mbit/s
13 = 17.6 Mbit/s
14 = 21.1 Mbit/s
15 = 23.4 Mbit/s
16 = 27.9 Mbit/s
19 = 35.3 Mbit/s
20 = 42.2 Mbit/s
21 = 23.4 Mbit/s
22 = 27.9 Mbit/s
23 = 35.3 Mbit/s
24 = 42.2 Mbit/s
25 = 46.8 Mbit/s
26 = 55.9 Mbit/s
27 = 70.6 Mbit/s
28 = 84.4 Mbit/s
HSDPA(High Speed Downlink Packet Access):高速下行分组接入
ry :
1 = 0.73 Mbit/s
2 = 1.46 Mbit/s
3 = 1.46 Mbit/s
4 = 2.93 Mbit/s
5 = 2.00 Mbit/s
6 = 5.76 Mbit/s
7 = 11.5 Mbit/s
HSUPA (high speed uplink packet access):高速上行链路分组接入
: 3G数据标准选择
0 – UMTS r99
1 – HSDPA
2 – HSDPA/HSUPA
nd:
0 – 关闭对AMR wideband /HD Audio的支持
1 – 打开对AMR wideband /HD Audio的支持
AMR WideBand,语音带宽范围,全称为“Adaptive Multi-rate - Wideband”,即“自适应多速率宽带编码”,
采样频率为16kHz,是一种同时被国际标准化组织 ITU-T和3GPP采用的宽带语音编码标准,也称 为G722.2标准。
AMR-WB提供语音带宽范围达到50~7000Hz,用户可主观感受到话音比以前更加自 然、舒适和易于分辨。
AMR-WB应用于EDGE、3G可充分体现其优势。足够的传输带宽保证AMR-WB可采用从6.6kb/s到23.85kb/s共九种编码,语音质量超越PSTN固定电话 。
PS:这里需要注意的是有些版本的Radio不支持AMR wideband,那样就算设置为1也支持不了这功能。
cant_scan_interval:
wifi无线局域网扫描间隔时间,单位为秒。
调大这个值可节约耗电。
ze=24m:
虚拟内存大小,单位为Mb,调大这个可以略微提高性能,对于某些FC问题确实有用。
在hdpi下,不设置成24m以上,就会导致系统无法启动。
:AGPS模式选择
0 – 关闭AGPS服务支持。可以节约耗电和网络流量,不过会延长GPS定位时间。
1 –
2 – 打开AGPS服务支持

[技术课程] ROM这些事_参数详解(二)
是Android系统中的一个重要的属性文件,它记录了Android系统的一些重要的设置信息,改变它能够取得一些意想不到的效果,但是也正是因为.prop的重要性,如果不
明白具体的含义的话,绝对不要随便动它。
今天,我们来看看如何对文件进行修改,以达成省电和加快上网速度的效果。
注意:修改前请先备份好文件!
第一步:打开你的R.E,并改成读/写模式
第二步:进入system目录,找到
第三步:右击(长按这个文件),会弹出菜单
第四步:找到“以文本编辑器打开”
第五步:加入下面的行,并最后保存。
第六步:重启两次
调整文件以取得更好的信号和数据传输速度:
=2
ass=10
=1
=1
ry=10
.a53=1
=1
k=4294967295
kw1=14449
ry=5
X最大测试到10,超过硬件限制,数据在高速下更稳定? 估计是WCDMA才有用??
(我們的MB860 要用10的哈哈---ry="X"
CAT Speeds
Cat 1 = 1.2 Mbit/s
Cat 2 = 1.2 Mbit/s
Cat 3 = 1.8 Mbit/s
Cat 4 = 1.8 Mbit/s
Cat 5 = 3.6 Mbit/s
Cat 6 = 3.6 Mbit/s
Cat 7 = 7.2 Mbit/s
Cat 8 = 7.2 Mbit/s
Cat 9 = 10.1 Mbit/s
Cat 10 = 14.0 Mbit/s
*Note*
You can play with the "=2" & "ass=10" values depending on your
location. The hsxpa Values range from 0-2 and the gprsclass is either 10,11 or 12. IF YOU
GET WORSE SPEEDS..JUST CHANGE THE "GPRSCLASS" TO 12
To save power while phone is asleep
//在手机休眠时更省电
se=1
To make the phone ring faster when
//使电话拨出时更快接通
_=1000
To make UI more responsive
//使界面反应更快
_events_per_sec=150
To save battery by decreasing the amount of time Wifi looks for an access point
//使WIFI在查找接入点时更省电
cant_scan_interval=150
**Now wifi will scan once every 1.5 minutes when not around a known location instead of
once every minute which will save battery.**
//现在wifi将每隔1.5分钟查找一次接入点而不是每分钟查一次。当你在一个没有已知接入点的地方。(估计是,如果你开WIFI了,如果没有连接到接入点,查找接入点的时间间隔改成了一分半钟)
Change the Dalvik VM heap size
(??? heapsize是栈的大小,是不是影响速度??)
ze=32m
**If on CM7 then you can just go into CM setting/Proformace to change this.**
To enable the hard key lights to stay on while the screen is on and not timeout
(保持屏幕常亮。。。。汗。。)
t=0
**Try disabling BLN if your having trouble getting this to work**
To make the phone come off of the "black screen" in the middle of, or the end of phone
calls when you pull the phone away from your face
(在通话中或通话结束时,当电话离开脸时,隔多久??重新亮屏?)
=150
***May kill the dialer***
To disable usb debugging popup
(禁止USB调试提示)
=0
**Some devs already have this disabled, or have an app to disable it.**
To give your phone an HD effect fitting a little more on the screen, look for this in you
current and change the
(给你的电话一个宽屏感觉??)
_density=X (225 or 230)
。。。。。。这样修改后,手机可能启动用时会长一点。。。。。
**Phone will take a little more time booting when changing this value**
To enable Stagefright..Helps stream Video/Music Faster but may not let you watch
(使能stagefrigh,视频和音乐会更快?但可能不能看你自己录的视频了。。)
(Press the enter key after every line typed)
-player=true
-meta=true
-scan=true
-http=true
To enable hardware acceleration where the GPU controls the UI instead of the CPU, giving
u a much better
(使能硬件加速,用GPU而不是CPU,给你一个更好的体验)
=1
。。。你可能会也可能不会注意到性能上有改变,因为vibrant有一个很好的cpu,哈哈
**You may or may not notice a difference because the Vibrant has a very good processor
thats capable of handling the UI very well**
To turn off the bootanimation speeding up the
animation=1
To enable the menu button too unlock
_menu_unlockscreen=true
To stop the phone from waking up when pressing the
ure_wakeupkey=0
小知识:什么是?
/system/ 是一个属性文件,在Android系统中.prop文件很重要,记录了系统的设置和改变,类似於/etc中的文件。这个文件是如何生成的呢?
build/tools/ 脚本就是专门用于生成文件
build/core/Makefile中使用build/tools/ 脚本生成文件,
并把系统默认的以及定制的中的设定追加到文件中
后面还有一些设备相关的配置追加到
