– The rate at which people make use of the 802.11AC routers is really massive but I will like to let you know that before the Wireless the AC routers came, the wireless N routers have been in existence. It’s not even about the longevity in the router scene; it’s about what the N routers can offer.
Nobody will dispute the fact that the new wireless AC routers are fast, but a major setback is that the routers hardware could become obsolete due to change (that probably won’t happen).But if you want to get a wireless router that has been in place for years for your work, then the N routers can be your option.
The Wireless N router is a wireless device that was created before IEEE’s certification. The N router is a proposed amendment to the wireless network in order to improve system performance.
I am sure most of us will feel there is no importance reading on the Wireless N router since the Wireless AC and Wireless AD routers are performing well, but I will like to inform you that there are lots of differences between the routers; each has its own edge over another.
I promise after reading this article, you will have a sound knowledge about the N routers, how they work, their features and some other important information.
To start with, the Wireless N router is a round-up of the N900 model i.e the N routers gives room for three 150 megabits per seconds (Mbps) spatial stream on the 2.4GHz frequency band and also supports three 150 megabits per seconds spatial stream on the 5GHz frequency band. This implies that the N router support 45ombps spatial stream for each band. If the 450 is multiplied by 2 (450 for 2.4GHz and 5 GHz) we will have 900Mbps which is the data throughput of the model.
Then 2.4GHz and 5GHz band are further divided into 11 channels each. Each channel is 20MHz wide, but of the 11 channels, only 3 don’t overlap each other. In order to reach 45oMbps, the router must have a bond of two of the 11 channels to give a band that is 40MHz wide. To avoid situations where one router will consume all the bandwidth in its environment, there is a policy that governs that. The policy is called the good neighbor policy.
The good neighbor policy is a designed law that does not allow bonding two of the non-overlapping channels; the policy also promotes channel bonding if only you find out that there are no routers operating in the same spectrum as yours.
The bottom line; Due to the issue explained above, it’s almost impossible to make use of this routers in a city environment because so many device will be operating at the same spectrum. The 5GHz has edge because of the more channels are available but it has a problem of less range delivery.
I know at this point you will start wondering why the wireless N has this problem since the wireless AC also operates on the 5GHz band. The reason behind that is because the AC router uses channels with more bandwidth. Unlike the Wireless N that has the channel width of 40MHz, the AC routers have channel width of 80MHz. Another reason is because the AC routers have higher density signal modulation scheme.
Without wasting much time let’s see the features of the wireless N routers.
The wireless 802.11n supports the Orthogonal Frequency Division Multiplexing (OFDM) implementation which increases the highest raw data rate to 248Mbps.
The router allows guest network. The guest network makes it possible to create a separate wireless network that can be useful for guests. The guest network gives visitors the avenue to access the internet but will impede them from accessing other PCs or storage device that is being operated on your network. The guest network can be a courtesy that can be offered from small business owners to their customers, individuals or families can also offer this to their visitors.
The 802.11n router also supports Multiple Input Multiple Output (MIMO) which uses a multi-path radio phenomenon called the space division multiplexing which makes it possible for the WLAN to split each data streams into multiple spatial streams and transmits each streams through different antennas. The MIMO helps increase the Wi-Fi performance.
The N router has backward compatibility; the N router has an extended coexistence management for the G routers, B routers and A routers.
The Wireless N routers also provide media server access. Music and videos can be streamed to client devices.
Parents also have control over the router, this shield their kids from accessing sites that have been restricted by their parents.
The N routers will definitely come with a USB port that can be used to share printers and other storage.
