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.

publication Tougher punishment more strict punishment Here's a quick review of the issue: What is net neutrality all about? The principle generally means that content isn' t prioritized above others, so that a user can go where he wants and do what he wants on the Internet without the interference of his broadband provider. supporters of net neutrality protections say that without the rules, Internet service providers like Comcast and Time Warner wil

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.

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

IPv6 adoption: Challenges and Choices, and ipv6 adoption challenges Today, many enterprises have begun to adopt IPv6 (Internet Protocol version 6th), and more countries are preparing to increase IPv6 traffic globally. As more and more devices connect to the Internet (such as smart cars, smart homes, and even smart cities), and the available IPv4 address pools quickly run out, today's network space has become more important than ever before. However, using NAT (Network Address Translation) as th
