Broadband wireless access technology is worth learning a lot. Here we mainly introduce the DOCSIS-based broadband wireless access technology, from the DOCSIS Protocol release to the current development trend, many related equipment manufacturers use DOCSIS Protocol in their 3.5 GHz MMDS products because DOCSIS uses man

Viewing a DOCSIS configuration file requires a specialized tool. Tool installation Under Windows, you can use the tool vultureware DOCSIS Config Editor.Under Ubuntu (native version 12.04), you can use the Open source project Docsis Project 's docsis Tools ( home page here ).Its code was previously in Http

In order to improve the spectrum utilization of the gold GHz band and expand the system capacity, the macro-cell adopts sector segmentation (optional sector angle), band refinement, and same-frequency multiplexing. Dynamic Power Control, antenna polarization, and frequency planning are used to overcome interference between different base stations and sectors. Optional values: 7 MHz, 3.5 MHz, and 1.75MHz. Optional values: 3.2 MHz, 1.6 MHz, 800 KHz, 400 KHz, and KHz. The broadb

+ C-DOCSIS: national standard technology, for China Radio and Television Network, compatible with the original CMTS system. • FTTH: it is still pilot and the CATV access method is unclear. In the FTTH solution, CATV access is divided into three types: Single-fiber three-wave, dual-Fiber Three-wave, and fiber-optic Coaxial Dual-household. Because a single-fiber three-wave adds one WDM module per household, the network construction cost is high, single

Cable TV Cable (Cable) mode broadband access to the Internet is the standard docsis (Data over Cable Service Interface specification), Recently this standard has been upgraded to 2.0, and Imedia announced in April the DOCSIS2.0 chip IM6030 and a reference design that can be mass-produced immediately. This means that the new cable cat and head-end equipment will be on the market time greatly accelerated, the cost can guarantee a lower level, which is c

The data transmission on the downlink channel is completed by different independent templates, and its proportional relationship can be flexibly and arbitrarily configured. Multifunctional Both one-way cable transmission (telco-return) and two-way cable transmission can be implemented in one rack without additional remote dial-up devices. Standard sex. Follow the DOCSIS 1.0 specification and can be upgraded t

17%. DSL and cable enterprises have developed new technologies, such as adsl2 + and DOCSIS 3.0, to improve network speed. In contrast, fiber development lacks new capabilities. The reason is that optical fiber has advantages, so it is not worried about threats from ADSL and cable. However, the disadvantage of optical fiber is that the deployment cost is too high. Hybrid methods have become a method for enterprises to build networks. British Virgin Me

Specification entity (entityspecification) defines a certain type of entity; Characteristicspecification defines attributes of one or more types of entities; Characteristicspecvalue defines the possible values of feature types; You can define attributes for productspecification, product, and customer. So how can we apply Sid's "Specification mode" and "feature mode?2. Introduction of specification mode and feature Mode The following uses the most common product display page of an e-commerce

carrier which is suitable for transmission through the modulation technology, the device that completes this task is called the cable modem (Cablemodem, abbreviated cm). Cable modulation and demodulation technology combined with amplitude and phase modulation can get high data load density, common QAM256, QAM64, QAM16 and QPSK. CATV system has rich broadband resources, and its use has been stipulated accordingly. In the PAL format, as shown in the following figure, the 5mhz-65mhz is the uplink

Two Computers in the family share the Internet and email broadband wireless connection. A layer-1 computer is connected to the STB/AP in 802.11g wireless mode. The location of the Second-layer computer may not receive the wireless signal generated by STB, so the remote antenna is connected to the antenna through a coaxial cable) to co

We strongly recommend that you use anti-virus software on the broadband access network, such as Norton, McAfee, TrendMicro, CA, rising, Kingsoft drug overlord, and beixin source VRV. ◆ Encryption: for particularly sensitive communication, you must consider encrypting the communication on the PC. A firewall with VPN protection can protect sensitive
