What about rural wireless network coverage?
A three-phase alternating current commutator motor is a three-phase alternating current motor with armature winding with a commutator (see DC motor) on the rotor. Also called three-phase asynchronous commutator motor or AC rectifier small motor. It is a constant torque AC speed regulating motor.The rotor winding with a sliding ring through the motor air gap magnetic field of the three-phase alternating current, its relative rotation of the rotor synchronous speed are s. If the rotor speed are to reverse rotation, the magnetic field is relative to the stator winding branches and commutator speed are the slip speed (DP s-, EMF and DP) stator windings and the commutator winding induced for slip frequency. It varies with slip rate (see asynchronous motor). However, the magnetic field has the relative speed fixed on the rotor (synchronous speed are s), so the commutator winding electromotive force and slip. The three-phase parallel commutator motor is equivalent to an asynchronous motor in which the external electromotive force (i.e., the electromotive force of the commutator winding) is fed into the secondary side winding (i.e., stator a, B and C windings). The difference is that the former is placed on the rotor and the secondary side on the stator.

Rural households are scattered and their density is not high. Wireline construction projects involve large quantities and cost-effectiveness. At the same time, there are problems with the management and maintenance of basic equipment. The general feature of rural areas is that buildings have a simple structure and a relatively low height, which is very suitable for wireless network applications. Providing broadband network access to rural areas through wireless coverage can greatly reduce the construction complexity and save network comprehensive costs. Industrial-grade wireless network equipment can operate stably under long-term unattended conditions, and it is convenient for free wireless networks. Let users enjoy the fun of advanced technology more freely and freely.
According to the inherent characteristics of rural areas, outdoor APs can be used to build wireless networks. The outdoor AP has features such as waterproof, lightning protection, and sun protection. It has the advantages of high speed, safety, simple installation, and easy use, and is more suitable for large-scale rural wireless coverage.
Rural wireless coverage has many advantages:
1. Easy to install, easy to expand, extremely high mobility and flexibility, easy to maintain, low maintenance cost 2. Compared to rural areas, sparse and complicated environment, wireless is easier to construct than wired and saves a lot It is cumbersome to pull wires and wires (in some places in rural areas, it is impossible to construct, wire, etc.), and a basic base station equipment can cover a wide range of areas;
3, wifi wireless Internet access is a standard for many handheld mobile terminals, such as: smart phones, PDAs, tablet computers, etc., to achieve remote scheduling, information transmission, sharing, management to provide convenient wireless transmission services anytime, anywhere;
4. The wireless network expansion is convenient and the maintenance cost is low. Compared with twisted-pair cables and optical fiber cables, the wireless network has a wide coverage area and can basically realize mobile Internet.
Compared with mobile, operators such as China Unicom's 3G Internet access package services, wifi wireless transmission coverage has a one-time investment, can be long-term operation, zero late investment, just renew the telecommunications broadband access service; and have high bandwidth, Access users, data stability, signal coverage and other characteristics, and 3G Internet services are generally in accordance with data traffic / monthly package package, tariffs are relatively high; and the majority of rural areas, 3G signal coverage is not very good, in some places there is no 3G Signal coverage, so compared to WIFI wireless coverage coverage is a good choice for broadband access.
Based on mature wireless products and technologies, Feng Runda provides complete and comprehensive wireless network solutions, and provides stable wireless links within the scope of manageable, scalable, technical resources and advantages of wireless networks. The use of advanced wireless network equipment to achieve wireless transmission from townships to villages requires rural users to be able to achieve wireless Internet access.
plan description:
The coverage equipment uses outdoor APRD-W360AP to build a 360-degree coverage group and adopts 802.11n MIMO wireless technology to provide 300Mbps wireless transmission rate, with stronger signals and wider coverage. Suitable for rural outdoor wireless network coverage, outdoor wireless coverage of the community, wireless coverage of the factory outside.
The RD-W360AP supports point-to-multipoint wireless connectivity, supports 802.11b/g/n standards, and wireless transmission rates up to 300Mbps. Compared with traditional 54Mbps 11G products and 108M products, it has higher wireless bandwidth, which makes data transmission in the LAN more efficient, can effectively reduce network delay, and makes voice video, online games, and online on-demand more smooth. The shell adopts industrial standard design, rainproof and dustproof. Built-in 14dbi directional antenna, and PoE power supply, easy to install. With wireless AP, WDS, a variety of client operating modes, a multi-purpose machine, a large limit to protect the user's investment.
