. Adjacent 2ndThe leakage power of the channel is less than-20dbm, and the leakage power of the adjacent 3rd channels and above is less than-40dbm. (7) modulation characteristics The initial status is the same as (3 ),EUT operates at low, medium, and high frequencies. The tester sends a Net Load of 11110000 to the maximum supported group length, and calculates the peak value and average value of the frequency offset for the EUT return group,Marked as df1maxAnd df1avg. The tester sends a Net Load

How to make mobile downloads fly together with LTE and Wi-Fi With the rapid popularization of 4G terminals, LTE seems to be the fastest-transmitting mobile network technology. However, with the gradual rise of 4 k hd videos, how can we further break through the transmission speed in mobile networks? Based on the current network resource configuration in Beijing, the theoretical peak rate of the downlink network is about 80 Mbps, And the uplink peak rate is about 20 Mbps, but limited by the ter

The 7th chapter deals with serial line and Frame Relay connection failuresI. Handling serial LINE faults1. HDLC EncapsulationHigh-level Data Link Control (HDLC) is a encapsulation method for a serial link, and HDLC is the default encapsulation method for the Cisco router serial interface.The first step in dealing with a serial link failure is to look at both ends of the link to use the same package type.Show interface serial 1; viewing interface informationClear counters serial number; Reset int

complex requirements on devices, but has high communication quality. 　　 Data bit: when data is transmitted through the modem online, each group of data transmitted must contain corresponding control data, including starting to send data and ending data, the most important part of this set of data is the data bit. In different communication environments, the number of data bit and second bit is generally specified. 　　 Traffic control: used to control the data flow between the modem and the com

1. Challenges faced by MacRF Link Quality802.11 adopt a positive confirmation mechanism. All transmitted frames must be responded to, as long as any one link fails, the frame is considered a loss. -------Atomic operationproblems with hidden nodesWireless transceivers typically have a half-duplex operation, which means they cannot send and receive data at the same time. Use RTS and CTS signals to clear the transfer area. RTS frames have two purposes: to reserve the right to use the wireless link,
