The second generation mobile communication system GSM mainly uses the time Division/Frequency Division multiple access wireless accessing way, its wireless network plan generally can divide into two steps. The first step is to forecast the loss of wireless path in order to ensure the wireless coverage of the required business area. The second step is to determine the capacity of the system by frequency planning based on estimates of the fields busines

In the past few days, we have been testing telit's 3G module uc864 and encountered the following problems. Fortunately, we finally solved the problems through our own tests. Problem 1: When querying the network registration type, the result value is always 4-indicates an Unknown network or an unregistered network. Solution: When you enter at # psnt? When querying the network registration type, the system needs to obtain the current network results and execute the command response for a longe

Wireless Internet access can be achieved in a variety of ways, such as surfing on the wireless network. Next, we will give a brief introduction to EDGE wireless Internet access, and make a rough comparison with the appropriate user groups based on the characteristics of each method. Hope to help you. What is EDGE? EDGE is short for Enhanced Data Rate for GSM Evolution, that is, Enhanced Data Rate GSM Evolut

Speaking of wireless, everyone will think of mobile. However, there is also a device that has been used as a wireless fixed-line phone. I believe it is not a stranger to everyone. As the name suggests, wireless fixed-line Alarms can also be imagined as functions and functions. The following is a brief introduction. Wireless fixed-line telephone, commonly known as "wireless" or "Mobile landline", is the appearance of ordinary telephones. Its core technology uses mobile communication systems, and

At present, Huawei P7 Unicom 4G version and mobile 4G version has got the network license, their models are p7-l00 and P7-L05 respectively. The former supports the TD-LTE/WCDMA/GSM network, and has dual SIM card function, while the latter supports the TD-LTE/TD-SCDMA/GSM network, but does not have dual-sim double function. Huawei P7 is the flagship of Huawei this year after Mate7, similar to the relationsh

Business travelers can go through a public network remotely, connect to a network within the enterprise through a virtual encrypted channel, and users on the public network cannot access the enterprise's internal network through virtual channels. At present, China Mobile has opened GPRS (General Packet Exchange

This reduces the load on the macro base station, so that the macro base station capacity mainly serves outdoor and sports users. On the other hand, it aims to cope with the competition between emerging wireless operators and mobile virtual network operators (MVNO. Because nearl
