The UI Signal display on the android interface is implemented by sending AT commands to the communication module through RIL. For example, at + CSQ, we can obtain real-time RIL information through logcat-B radio.
So how long does the signal display refresh on the interface?

Android system transplantation and debugging -------) how to modify the number of 4G signal strength grids displayed on Android phones
Before modifying the displayed signal strength, let's take a look at what is dB and what is dBm?
1. dBDB is a value that represents relative values. A pure ratio represents only the rel
In wireless coverage engineering, it is often necessary to test the wireless signal strength of the field to determine if the wireless signal is in place and whether the wireless signal strength meets the requirements. Wireless WiFi and sound, the
Recently to be in the running to find a job, inevitably in the interview process encountered such a problem, remember the most clearly in the interview process was asked, when the mobile phone in a weak network state, how to deal with, how to monitor the network signal intensity changes. But it was so, the answer was messy, the idea was not clear at all. Today's small knitting here to lead you to understand the mobile phone
power size value. In dB and DBM computing, pay attention to the basic concepts,
When one DBM is used to subtract another dBm, the result is dB, for example, 30dbm-0dbm = 30db.
3. Cell phone signal strength Representation
Okay, soMobile phoneThe unit of the number shown on is dBm. When you look at it carefully, you will find that the value is negative. That is to say, the phone will display-67 (DBM),
Android phones get signal strength informationThis document describes how to use the Android system to get mobile phone signal strength and other information
Android phones get signal strength information
With the development of wireless networks in China, many families have begun to use wireless routers, but it is a headache for users with weak signals. I will give you an analysis here. Wireless signal strength is a concern of the majority of users, who want their own Wireless Router network signal to cover every corner of the room, especially where wireless Inte
Application background
Different area of the environment, the router signal emission intensity requirements are different. Under the condition that the signal quality is guaranteed, the larger the area (obstacle) is, the higher the signal strength is required. In a small environment, the

Wireless signal strength is a concern of the majority of users. Everyone wants their wireless network signal to cover every corner of the room, especially where wireless Internet access is needed, otherwise, it cannot be truly wireless. However, many of my friends are very frustrated after buying a wireless router. Most of them are abandoning wireless application
Label: cc1101Before reading this article, read the data manual carefully and read the two articles I have reproduced, CCA (1) and CCA (2), for literacy.I have been using the CC1101 wireless chip recently. I have successfully debugged the CCA function today. I 'd like to share it with you. My idea is to enable the CC1101 to be the CCA function. The GDO2 pin is configured as the output carrier sensing level and the sensing level threshold is set. Currently, the carrier

WiFi Wi-Fi has become almost an essential element in modern life, and your smartphone, tablet, computer and even TV all need to surf the web. When it comes to improving the "speed", basically need to consider from two aspects, one is to promote broadband bandwidth, the second is to strengthen wireless signal. Because wireless signals are generated by a wireless router, and the routers are different because of brand or performance, the
First, Application Introduction
Different areas of the environment, the wireless transmitter power requirements for routers are different. The signal quality is guaranteed under the premise of the larger area (barrier) in the environment, the higher the wireless power requirements. In a small environment, the wireless power of the router is adjusted to a lesser size, which can save energy, reduce the possibility of rubbing the net and reduce radiat
