NBC 255-W and 265-W Wireless Connection GuideObjective: This wireless connection guide is designed to assist with establishing wireless connectivity between typical commercially available wireless routers and Bosch NBC 255-W / NBC 265-W cameras.Minimum prerequisites prior to starting:• The NBC Camera should be assembled as per the directions of the quick installation guide provided with the camera o Wireless antenna is attachedo SD card is installedo Power adapter is connected to the camera• Bosch Video Client and Configuration Manager software should be installed on your PC • A physical Ethernet connection to the camera established • Access to an 802.11 B, G, or backwards compatible N wireless router o NOTE: If using an 802.11N router, review the manufacturer’s specifications for compatibility with 802.11G products. Ifthe router is not backwards compatible it will not communicate with the camera .Step 1: Assigning an IP address to the NBC CameraThe first step in establishing wireless communications is toassign a static IP address to the NBC camera. Open theConfiguration Manager application on your PC.• Once the program is opened you should see the NBC camera appear in the “Network” column asshown. By default all Bosch encoders and networkcameras come with a factory default IP address of192.168.0.1.•Manual Assignment: You can assign an IP address manually or by using the Configuration Wizard. Wewill cover the manual method first. Simply right -clickthe camera in the “Network” column and the select“Device Network Settings…” as shown.• Once the “Network settings” menu is open enter valid IP address information for the desired network andselect “OK”. After selecting “OK: the camera will reboot.o NOTE: Most off-the-shelf home wirelessrouters come preconfigured in a 192.168.1.xaddress range (Private C Class Address).For this guide we will use an address of192.168.1.200.• Using the Configuration Wizard: To assign an IPaddress using the wizard, select the “Tools” menu and “Configuration Wizard…” from the drop downmenu as shown.•Once the “Wizard” opens follow the prompts until you come to the “Network” menu. From this menu select“Use the following IP address settings” and entervalid IP addressing for the network in which thedevice will operate.o Follow the “Wizard” prompts until you havethe reached the “Summary” page. Select“Finish”.Step 2: Establishing wireless communication• Once you have assigned a valid IP address to your NBC camera navigate to the “Network” menu and the“WLAN” submenu as shown.• From the “WLAN” submenu select “Auto” in the “Activate” drop down menu as shown here. This turnson the camera’s radio.•Next select the proper region from the “Region code” dropdown menu as shown. In this guide we will use “USA (FCC)”• Select the “Scan” button. Once the wireless network scan is complete you will see a list of availablewireless networks with which to establishcommunications. Select the wireless access point towhich you wish to connect. This will auto-fill the SSIDmenu with the Service Set Identifier of the router youselected.o NOTE: NBC-W cameras will communicateto 802.11 B and G routers using WPA andWPA2 encryption.oIf there are multiple routers detected, bestpractices dictate that the routers should beat least 6 channel numbers apart to preventinterference in communication.o If the wireless router you are working with isin hidden mode you can manually enter theSSID and PSK.• Enter the “pass key” to access the wireless router in the PSK menu as shown.o NOTE: The wireless router you areconnecting to must have security enabledfor the NBC camera to connect.•Select the “Save” button and immediately disconnect the Ethernet cable from the camera!Once you select “Save” the camera will reboot andthe network changes will take effect. The camera willnot function in wireless mode while an Ethernetcable is attached. If the camera does not reboot, youmust cycle power.Step 3: Validating wireless communication• Disconnect your physical network connection and ensure your PC is connected to the desired wireless network. Close theConfiguration Manager application and re-open it. This will ensure that the application’s detection beacon is using the wireless network and not the wired network.• Right-click the camera’s icon in the “Network” or “Devices” tab and select “Show in Web Browser”. This should open the camera’s web page.• From the Web Browser you can mouse over the “WLAN” menu in the top right hand corner. This will display the current signal strength of your wireless network to the camera.。

WiFi技术的原理及未来发展趋势时间：2021.03.12 创作：欧阳文文章出处：作者：张春飞WiFi——Wireless Fidelity，无线保真技术与蓝牙技术一样，同属于在办公室和家庭中使用的短距离无线技术。

该技术使用的是2.4GHz附近的频段。

其目前可使用的标准有两个，分别是IEEE802.11a和IEEE802.11b。

该技术由于有着自身的优点，因此受到厂商的青睐。

什么是WiFi？WiFi全称Wireless Fidelity，又称802.11b标准，它的最大优点就是传输速度较高，可以达到11Mbps，另外它的有效距离也很长，同时也与已有的各种802.11 DSSS设备兼容。

IEEE 802.11b无线网络规范是IEEE 802.11网络规范的变种，最高带宽为11Mbps，在信号较弱或有干扰的情况下，带宽可调整为5.5Mbps、2Mbps和1Mbps，带宽的自动调整，有效地保障了网络的稳定性和可靠性。

其主要特性为：速度快、可靠性高。

在开放性区域，通讯距离可达305米；在封闭性区域，通讯距离为76米到122米，方便与现有的有线以太网络整合，组网的成本更低。

WiFi——Wireless Fidelity，无线保真技术与蓝牙技术一样，同属于在办公室和家庭中使用的短距离无线技术。

该技术使用的是2.4GHz附近的频段。

其目前可使用的标准有两个，分别是IEEE802.11a和IEEE802.11b。

该技术由于有着自身的优点，因此受到厂商的青睐。

WiFi技术突出的优势其一，无线电波的覆盖范围广，基于蓝牙技术的电波覆盖范围非常小，半径大约只有50英尺左右，约合15米，而WiFi的半径则可达300英尺左右，约合100米，办公室自不用说，就是在整栋大楼中也可使用。

据悉，由Vivato 公司推出的一款新型交换机。

该款产品能够把WiFi无线网络300英尺接近100米的通信距离扩大到4英里约6.5公里。

其二，虽然由WiFi技术传输的无线通信质量不是很好，数据安全性能比蓝牙差一些，传输质量也有待改进，但传输速度非常快，可以达到11Mbps，符合个人和社会信息化的需求。

双频wifi是什么意思有什么功能宽带路由器在一个紧凑的箱子中集成了路由器、防火墙、带宽控制和管理等功能，具备快速转发能力，宽带路由器灵活的网络管理和丰富的网络状态等特点。

这篇文章主要介绍了双频wifi是什么意思?双频wifi技术介绍,双频WiFi指得是一台无线设备(无线路由器、无线AP 等)同时提供了2.4GHz和5GHz两个频段的无线WiFi信号,其属于第五代Wi-Fi传输技术,需要的朋友可以参考下方法帮助双频WiFi值得是一台无线设备(无线路由器、无线AP等)同时提供了2.4GHz和5GHz两个频段的无线WiFi信号，可支持包含802.11a/b/g/n 完整无线网络，其属于第五代Wi-Fi传输技术(5G Wi-Fi)。

首先大家要知道，无线路由器发射的无线WiFi信号都是有一个无线频段的，之前的无线路由器使用的都是2.4GHz频段的无线信号，随着802.11 ac技术的成熟，5GHz频段的无线信号也被用在了无线路由器上，同时该技术向下兼容2.4GHz频段的无线WiFi信号，所有就有了我们所说的双频WiFi。

目前市面上已经有一些无线路由器开始支持双频WiFi信号了，例如TP-Link、华为、水星、腾达、小米等厂商生产都已经推出了自己的11ac 千兆无线路由器。

这里要说明一下，腾达是最先在国内推出5GHz无线路由器的厂商，早在2012年11月的时候，推出了国内首款5G WiFi 千兆无线路由器W1800R，5G频段无线速率最高达1300Mbps，无线并发速率高达1750Mbps。

双频WiFi无线设备的优点在于无线WiFi信号的传输速度更快速、信号更加的稳定、并且可以让无线设备更加的省电，5G WiFi的入门级速度是433M，这至少是现在Wi-Fi速率的三倍，一些高性能的5G Wi-Fi还能达到1G以上，可以满足未来高清以及大数据传输的需求;同时对于提升智能手机电池的使用时间也有一定的帮助，因为我们的智能手机大多数时候都是连接无线路由器的WiFi来上网的。
