Abstract
The utility model discloses a WIFI conversion device capable of converting 5.8G frequency into 2.4G frequency. The WIFI conversion device is characterized by being composed of a body (1), a CPU (2) arranged in the body (1), an RF chip (3) which is connected with the CPU (2), and a 5G double-directional amplifying circuit (4) which is connected with an uplink port of the RF chip (3). The WIFI conversion device can maintain the uplink and downlink signal balance between a hot spot AP and the WIFI conversion device to the fullest extent, thus effectively reducing the external interference and effectively inhibiting the system noise rise and the system capacity decrease.
Description
Technical field
The utility model belongs to communication field, specifically is meant a kind of WIFI conversion equipment of 5.8GHz frequency commentaries on classics 2.4GHz frequency.
Background technology
At present; Commmunication company has all arranged the WIFI focus AP of 2.4GHz and 5GHz in a lot of sub-districts and public place, though these focuses AP signal is very strong in launch point intensity, and stopping and disturb along with wall, glass and other buildings; When these focuses AP signal arrives the community resident user; Its signal intensity attenuation is just very big, actual signal very a little less than, thereby the computer that causes a lot of familys to be used can't connect this focus AP through WIFI.
In order to address this problem, realize comprehensive covering of focus AP signal, just must adorn a relay (being amplifier) at resident's family, amplify this focus AP signal.But,, be 2.4GHz also therefore with regard to requiring the last signal frequency that discharges of these relays because the operating frequency of most PCs all is 2.4GHz.In real work; If people adopt the relay (be 2.4GHz frequency advance the 2.4GHz frequency go out) of 2.4GHz-2.4GHz type; Not only its cost is higher; But also bring very big interference can for focus AP, and can cause system noise to rise and power system capacity decline, be unfavorable for promotion and application.
The utility model content
The purpose of the utility model be to overcome present focus AP signal adopt in during stage arrangement its cost higher, disturb bigger; And can cause the defective that system noise rises and power system capacity descends, provide a kind of 5.8GHz frequency to change the WIFI conversion equipment of 2.4GHz frequency.
The utility model is realized through following technical scheme: a kind of 5.8GHz frequency is changeed the WIFI conversion equipment of 2.4GHz frequency; Main by body, be arranged on the CPU of this body interior, the RF chip that is connected with this CPU, and the two-way amplifying circuit formation of the 5G that is connected with the uplink port of this RF chip.
Further, on said CPU, also be provided with SPI FLASH interface; On said CPU, also be provided with synchronous DRAM.
In order to realize the utility model preferably, the two-way amplifying circuit of said 5G is the two-way amplifying circuit of 20dBm; The model of described CPU (2) is 8192DR.
Simultaneously, this body is the router that has the RJ45 joint, supports the POE power supply.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model overall structure is very simple, and cost of manufacture is comparatively cheap.
(2) the utility model can keep to greatest extent and focus AP between the uplink and downlink signals balance, effectively reduce external interference, effectively suppress the rising of system noise and the decline of power system capacity.
(3) the utility model adopts the WAN/LAN1 mouth to support PASSIVE POE power supply, thereby guarantees that the utility model can support that netting twine zooms out, and makes things convenient for workmen's site operation of operator.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Wherein, the Reference numeral name in the above accompanying drawing is called:
The 1-body, 2-CPU, 3-RF chip, the two-way amplifying circuit of 4-5G, 5-SPI FLASH interface, 6-synchronous DRAM.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the execution mode of the utility model is not limited thereto.
Embodiment
As shown in Figure 1, the body 1 of the utility model is for having the RJ45 interface, but can realize that PASSIVEPOE power supply and netting twine zoom out the WAN/LAN1 type router of function, and corresponding, it provides the DC POWER module of power supply at promising its all circuit structures of set inside.
Simultaneously, also be provided with the CPU 2 of the 8196C/400MMIPS type that is used to control all data-signals in the inside of body 1, be used for that radiofrequency signal receives and 3 of the RF chips of conversion are connected with this CPU 2.In order to ensure result of use, it is the 8192DR type that this RF chip 3 adopts model.This RF chip 3 is 2*2, the WIFI radio frequency chip of 2.4G/5G double frequency, and he can be the 2.4G of 2*2, or the 5G of 2*2, can also be the 5G of the 2.4G+1*1 of 1*1.
The utility model utilizes the 1*15G part of 8192DR chip to be upstream cell, removes to insert focus AP with the CLIENT pattern; Utilize the 1*12.4G part of 8192DR chip to be downstream units simultaneously, remove to provide the WIFI equipment of service to family with ap mode.Existing other 5G in market change the product of 2.4G; All adopted the design of two network interface cards; Cost just rises like this, and the utility model is exactly to have made full use of the characteristics of supporting 1*12.4G/5G dual concurrent in the very ripe at present 8196C+8192DR router design.
Also be provided with the two-way amplifying circuit 4 of 5G in body 1 inside, the two-way amplifying circuit 4 preferential very two-way amplifying circuits of ripe 20dBm of technology that adopt of this 5G.During connection, the two-way amplifying circuit 4 of this this 5G is connected with the 5G port of RF chip 3, to guarantee the 5G conversion of signals that receive being become the 2.4G wireless signal through this RF chip 3.
In order to ensure result of use, the utility model also is provided with SPI FLASH interface 5 and synchronous DRAM 6 on CPU2.
WLAN sends signal in the base station; When home terminal received signal: the 5G part upstream cell of the utility model adopted CLIENT pattern and wireless base station (the focus AP of China Mobile) to connect; The data that receive are handled the back through CPU 2 and are transmitted to Ethernet interface or 2.4G downstream units; Home terminal is through the wireless client pattern of 2.4G or wired DHCP, and wired mouthful of repeater or 2.4G downstream units in the connection are to obtain the data that the WLAN base station issues.
Otherwise; When the WLAN base station received signal; When home terminal sent signal: 2.4G downstream units of the utility model or Ethernet interface were received the data that home terminal sends, and handled to the 5G upstream cell through CPU8196C and transmitted, and the 5G upstream cell is given the WLAN base station data penetration transmission.
As stated, just can realize the utility model preferably.
