Enterprise networking for Chrome devices
When deploying Chrome devices in a business or school, you can set up a wireless network much the same way you would set up an office or classroom full of laptops or tablets. You want to make sure that you have the following:
- Good wireless coverage
- Sufficient Internet bandwidth
- Wireless access points that can handle the number of devices you want to connect.
Recommended networking configuration
|Wi-Fi||802.11n 5 GHz. Use non-DFS channels when possible. See 5 GHz channels for a table of non-DFS channels in your country. In the USA, those are channels 36-48 and 149-165.|
|Bandwidth||At least .2-.5 Mbps per user in a typical deployment. Latency should be less than 100ms when pinging Google's public DNS server at 220.127.116.11. For HD video streaming and HD Hangouts, at least 1 Mbps, preferably 2-5 Mbps or greater per user.|
|Access points||30 devices per access point. Enterprise-grade access points can handle more. Please refer to the product’s documentation.|
|Policy Refresh Rate||You can specify between 30 to 1440 minutes as the interval for the Chrome device(s) to sync new policies from the Admin console.|
See below for more information about the items in the table.
The access point should support Wi-Fi 802.11a/g/n. Google recommends 5 GHz 802.11n connections with WPA2-PSK encryption.
- For small deployments of under 30 devices, consumer-grade networking equipment is sufficient.
- For deployments greater than 30 devices or involving multiple rooms, enterprise-grade, centrally managed networking equipment is recommended.
Because of the high density of laptops in a classroom or workplace, network design is important. If you use multiple Wi-Fi access points in a small space, avoid using overlapping Wi-Fi channels to prevent interference. You can test your Wi-Fi strength and coverage using the Wi-Fi Analyzer Android app.
The amount of network bandwidth you need depends on how the Chrome devices will be used. For general web browsing and editing Google Drive documents, 0.2-0.5 Mbps per concurrent session at a minimum should provide satisfactory performance.
If your employees or students will be streaming video or using Google+ Hangouts, at least 1 Mbps per concurrent user session is needed and >4 Mbps is required for HD video streaming.
Latency may be a greater indicator of user perception of performance than bandwidth for interactive web-based applications. Generally, <100 ms ping is needed for a good experience.
For large Chrome device deployments, consider conducting a wireless infrastructure and topology survey of all the buildings to make sure that you will have adequate wireless coverage. You can contract with a firm that specializes in the following:
- Site Survey: First analyze both your existing Wi-Fi network along with surrounding interference from devices/other Wi-Fi networks.
- Deploy: Deploy/reposition access points with proper security and channel.
Note: See Set up SSL inspection on Chrome devices for information on how to set up networks with SSL content filters.
What are the maximum number of HTTP connections I can make with a Chrome device or browser?
- The maximum number of connections per proxy is 32 connections. For more details, see the Chromium site.
- Maximum per Host: 6 connections
- Total HTTP pooled connections per browser: 256 connections
- You can also verify what the limits are by going to chrome://net-internals/#sockets. You'll see a column titled Max Per Group which indicates the connection per host limit.
