, namely 1.4mhz,3mhz,5mhz,10mhz,15mhz,20mhz. The lower bandwidth of 1.4MHz and 3MHz allows for easy CDMA2000 use of the spectrum to be migrated to LTE while helping to facilitate the migration of GSM and TD-SCDMA to LTE. The purpose of a variety of bandwidth is to adapt to different frequency of the use of the scene, such as the frequency of the available bandwidth of less than 10MHz, then the LTE system can be configured to 5MHz use.not all channel bandwidth can be used as a resource for transm

IntroductionEthernet is the most successful LAN (local area Networking) technology in the last 30 years. 1. First widely used LAN technology (a widely used LAN technology) 2. Kept up and speed race:10 mbps–100 Gbps 3. connectionless: No handshaking between sending and receiving NICs (network Interface card, network card) No connection is established. 4. unreliable: receiving NIC doesn ' t send ACKs or nacks to sending NIC Not reliable. Ack:acknowledgement, that is, the confirmation character, in

, and the station site should be determined for a lot of new stations; compared with GSM, WCDMA network capacity is more sensitive to the regularity of honeycomb structure, more stringent to station site and antenna height, and requires large-scale redesign of network. Scheme two: A large number of micro-cellular, deployment of layered Network (HCS), the macro-honeycomb and micro-cellular settings to different levels, the use of specific cell re-election or switching algorithms, will be in the

For the public and most military fans, the famous military generals during the Second World War were nothing more than those of Eisenhower, nimiz, Montgomery, longmmel, and Zhukov. But one of them is little known. This guy is neither a marshal nor a marshalThe fifth star was a low profile and even refused to show off the limelight. However, his path exists among the stars of World War II. He is the "general in the general" sprunns (Raymond Ames Spruance) Admiral.During the attack on Pearl Harbor

CDMA was proposed by Qualcomm in the early 90, and IS-95 is the first standard to be released in the Cdmaone series, and the first CDMA standard that is really widely used globally is is-95a, on the basis of is-95a, Also published separately to support the 13K Voice Encoder TSB74 Standard, support 1.9GHz CDMA PCs system STD-008 standard, support 64kbit/s data service is-95b. When the ITU solicited the third generation mobile communication wireless candidate technology, IS-95 due to commercial s

). Step Two: Add the carrier file. The carrier can be MP3, MP4, PDF, JPG, smoke to exe file can be used to store secret files. Click the Add button at the bottom left of the interface to select multiple carrier files to open. Openpuff will be based on the hidden file size, automatically choose the number of the rumor to the

line, and exclusive bandwidth. Circuit Switching Mode: the connection between user devices is established on demand. When the user needs to send data, the carrier switch connects a physical data transmission path between the caller and the called end. When the user does not send data, the carrier switch disconnects the transmission path. Group switch: This is an exchange method based on the carrier's group
