NanoStation M2 for large files: transfer speed or waiting time?
The catalog image of NSM2. configuration and the composition of the proposed delivery are confirmed separately.
Request NSM2The buyer of inter-platform communication often needs a specific result: transfer the archive in five minutes or unload the work files before the shift begins. For the NanoStation M2, it is more useful to start with the amount of data and the allowable time than to compare advertising megabits of radio parts with the speed of a wired network.
One file goes all the way.
File exchange depends on disks, applications, local area network, wired ports, and radio connections. The official Ubiquiti guide for NSM2 lists two 10/100 Ethernet ports. For a single stream passing through one such port, the radio part count does not turn that portion into gigabit Ethernet.
PHY numbers, total radiolink score, and useful copy speed describe different things. Service exchanges, retransmissions, other users, and endpoints affect the outcome. Therefore, the number “150+” in the previous materials of the model is not a promise of the speed of one file on the customer’s computer.
Training calculation: 10 GB in five minutes
Take the decimals. 10 GB: 10 billion bytes, or 80 billion bits. If this data needs to be transmitted in full, without compression, deduplication and omission of existing parts, 300 It takes about a second. 267 Mbps of usable speed. One port 100 This requirement does not close, even before discussing the radio line.
With perfect. 100 Mbit/s transfer of the same volume would arithmetically take 800 seconds 13 minute 20 Seconds, without protocol costs and pauses. This is the lower calculation boundary for the selected example, not the measured result. NSM2. The actual time is agreed upon under the terms and conditions of the required exchange.
When the deadline is milder, the choice changes.
If half an hour is allowed, for the same 10 GB, the estimated need is about 44.4 Mbps of useful data. This is not a guarantee that a particular plant will provide such a flow: now you need to evaluate the radio line and the rest of the network. But the requirement is already formulated so that the quotation can be compared by the result.
For periodic uploading of documents or photo archives, not only the size of one file is important. Indicate how many transmissions go through at the same time and whether there is constant background traffic. They can not be quietly excluded from the task, and then explain the long transmission by the fact that “the radio bridge works.”
Two ports: not automatically speeding up a copy
Having two NSM2 ports does not mean adding up their speeds for a single wired session. At the same time, this is not a reason to claim that the sum of any streams through all device interfaces is always limited to one number of 100 Mbit / s. To order, you need a specific data route and load on its sections.
In our NSM2 card, it is listed for RUB 20,000 per device. The number of machines, power supply, mountings, cables and work are agreed on the project: the price of one item is not the price of the mounted bridge. In the request, name the amount of the archive, the desired period, the number of parallel tasks and the city of delivery - we will select the quotation for the requirement.
| Fully transmitted volume | Desirable term/calculation |
|---|---|
| 10 GB in 5 minutes | About 267 Mbps of useful data; one 100 Mbps port is not suitable |
| 10 GB at an ideal 100 Mbps | 800 seconds without overhead; no measurement of the device |
| 10 GB in 30 minutes | Approximately 44.4 Mbps; achievability requires an entire path evaluation |

Questions before buying
Two 10/100 ports give one file 200 Mbps?
The presence of two ports does not give this result. The route of a particular stream and the possibilities of all its sections are considered.
13 minutes and 20 seconds – the promised NSM2 time?
Nope. This is an ideal calculation for transferring a decimal 10 GB through 100 Mbps without compression and overhead. There is no real measurement in the article.
Does the price of 20,000 RUB include a ready bridge between the platforms?
Nope. This is the price of the device on our card. Appliances, power supply, accessories and work are agreed as part of a specific quotation.

Delivery to Russia and Kazakhstan. Indicate the city and the composition of the order - agree on the cost and delivery time. Availability, condition and configuration are confirmed before ordering.
Request NSM2Primary source of interfaces: Ubiquiti NanoStationM/locoM. NSM2 with two ports is considered here, not locoM2. Calculation of time is a conditional example of the editorial board.
File exchange between workspaces
For two units in Krasnoyarsk, write down the archive volume, the allowable transfer time and the simultaneous load. If another line connects the sites in Divnogorsk, prepare a separate scheme of computers, wired sections and radio connections. A single order for the NanoStation M2 does not confirm the same copy time for different sites. In the application, specify the program and the work operation for which the result is evaluated; an agreed check is carried out throughout the line. Equipment location and installation address help describe the project, but do not replace flow and end device data.
