network management system. The base station and the client are composed of an outdoor unit (a microwave transceiver and an antenna) and an indoor unit (modem), which is connected by an air interface. LMDS is operated in a bit multiple access mode, similar to a microwave, but unlike a traditional microwave, lmds can form a cellular network operation.The LMDS working band has 24GHz, 28GHz, 31GHz, 38GHz and 40GHz. In the United States, LMDs uses a band

transmit wireless signals to the desired places. 2.4Ghz or 5Ghz We can hardly find that many wireless routers are in the 5G band. So what is the wall-crossing Effect of vrouters with 5g frequencies? In fact, 2g is better at penetration than 5g. The advantage of 5g is that the transmission distance is far from 2G and m

Scenario Description: My host is Windows 7, virtual machine is wmware, which is installed in the linux-ubuntu10.04 version. The disk partition of the virtual machine is not enough and you want to resize it. 1) First, go to Linux in the VM and run sudo fdisk-L to list the disks.

Topics: There are 10G integers in a file, which are ordered in random order to find the median. The memory limit is 2G. Just write the idea (memory limit of 2G means that you can use 2G of space to run the program, regardless of the memory of other software on this machine).About median: The data is sorted, the position is in the middle of the number. The data is divided into two parts, part of which is larger than the value, and part is less than that. Median Position: median = (n+1)/2 when the

June 11, 360 security routes held a new product launch in Beijing. A total of three new products, including the price of 59 yuan only 360 safe Route Mini, the official price of 139 yuan and the signal transmission distance increased 42% of the 360 secure Route 5G, and by the 360 security route P1 derived from the colorful series (a total of seven colors).650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/6E/60/wKioL1V6nFmCYQ3RAAHeVtdVMMQ132.jp

flexibility and easy expansion and other advantages, LMDS system broadband and Low-cost also meet the current user demand for broadband services. Xi ' An mobile communications branch has carried out a series of planning and testing, the goal is to build XI ' an public network exchange platform and a variety of local information platform, the first phase of the project using four LMDS base stations covering the entire XI ' an, the backbone of the network using LMDS high-speed switching technolog

The system is currently the world's most mature lmds system, mainly for users to provide multi-channel television programs, the price is lower than their competitors 30%, by the end of 1997 has a user of 12

In 2000 more manufacturers launched the 800nm-band Broadband Wireless Infrared optical access system, become a veritable "wireless fiber."Generally s

Dual-frequency WiFi refers to the simultaneous transmission of 2.4g/5g band of dual-frequency terminal equipment. Double frequency. Maybe the users are still foggy about WiFi dual-band WiFi, and we're going to take you today to see what a dual-band WiFi is. Let's start with a history of WiFi, the 1999 802.11a defines a physical layer with a data transfer rate of up to 54mbit/s on the 5GHz ISM band, 802.11B defines one on the 2.4GHz ISM ba
