Mobile Data Networks Understanding 2.5G vs 3G vs 4G

文章目录 : 其他

Real 4G comes? Let’s understand what real 4g and fake 4g.

Some people call HSPA+ as 4G, actually there is a real definition of 4G networks.

Ever since Some carriers launched their HSPA+ 4G data services in some countries a lot of people have been saying “it’s not ‘real’ 4G”. But what is ‘real’ 4G anyway? Who decides what 4G ‘is’? Let’s look at the mobile networks that have been deployed, from GPRS 2G to 4G HSPA+.

Just to answer the question of who controls the classification “4G” – the International Telecommunications Union (ITU), a body created under the United Nations regulates the global telecommunications industry. One of the core mandates of the ITU is to establish worldwide telecommunications standards, and they determine the official classification (2G/3G/4G) of mobile data networks such as GPRS, EDGE, HSPA+, WiMAX, etc.

Does your application require 4G LTE or can you get by with 3G or 4G HSPA+?

Depending on your application you may or may not need to have a device that supports 4G LTE. For example, take most Kiosk, ATM and POS applications, most transactions or data transmissions with be in KB, not MB’s so LTE isn’t as crucial. However, if you’ll be using these for occasional remote surveillance or digital signage applications the additional speed LTE offers could be a big factor to consider upgrading to 3G/4G LTE supported hardware. When you answer this question it will help you narrow down which equipment you should focus on.

Seven Steps Connecting to a VPN server or router in win7

Seven Steps Connecting to a VPN server or router in win7

Step 1. In the Network and Sharing Centre (under Control Panel, Network and Internet), there is an option to “Set up a new connection or network.” The next step is to click on “Connect to a Workplace” in order to start the connection wizard, and then select “Use my Internet connection (VPN)” option to begin the process. If you have a 3G card installed, first of all you may see a prompt to use the 3G card instead of creating a “new” connection. In this case, you want the “new” connection so that you can use your existing Internet connection (yes, it’s a little confusing).

A far easier way to get to this point is to click on the Start button and type “VPN” in the search box. It will jump straight to the “Set up a virtual private network (VPN) connection” window in the wizard.

Step 2. In the Internet address field, enter the IP address of the VPN server or the network’s domain name. This information will usually be provided by the network administrator. If you are connecting to the home router, then you would put in the IP address of that router.

The destination name field displays the name users would see. If you aren’t going to connect right away, tick the “Don’t connect now; just set it up so I can connect later” box.

Leaving it unchecked means the client will try to make a connection at the end of the wizard. If there are multiple users on the Windows 7 box, you can either tick ”Allow other people to use this connection” to make the VPN connection available to others, or leave it unchecked to ensure no one else has the option.

Step 3. The next screen asks for a username and password. If you leave it blank, you will be prompted to enter the information when making the actual connection.

Step 4. The final window, if you selected “Don’t connect now,” will display a “Connect now” option. You can close the window now, or connect.

When you are ready to connect, just click on the network icon in the system tray (the icon could be for the wireless network or for the wired one) and the connection that was created earlier will show up in the list under “Dial-up and VPN.” You can also get here by clicking on “Connect to a network” under the Network and Sharing Centre.

Step 5. In the VPN connection box, enter the username and password to the VPN network, if it isn’t already pre-populated, along with the domain provided by the administrator. This connection should work for a majority of VPN networks.

Step 6. If the connection fails, click on Properties. The most common issue pertains to the server configuration. Select the “Security” tab in the Properties window. The “Type of VPN” should be set to Automatic. Check with the administrator if it should be set to PPTP, L2TP/IpSec, SSTP, or IKEv2. If it still doesn’t work, it’s possible you should uncheck “Include Windows logon domain” under the Options tab.

Step 7. After saving the properties, select Connect to launch the connection. You are now connected to a VPN server and your connection is safe.

Try A New DNS Server With A Fast Internet Connection

When you type an address such as into your browser, your computers uses DNS to look up and translate that name into a computer-friendly IP address. Sometimes, though, the servers your computer uses to look up that information can have issues, or go down entirely. Check out our guide to finding the fastest DNS servers for more information. If your default DNS servers aren’t having problems, then you probably won’t find too much of an improvement with an alternative server — but it might speed up your browsing by a few milliseconds, at least. One reminder: if your provider offers unmetered browsing for services such as iView, be cautious when changing DNS details, since this can mean those services are metered and will count against your download allowance.
