Comparison Of 802.11 Technologies And Router Recommendations

802.11 Technologies

1. Which ones use MIMO?   And what is MIMO anyway?   Write a paragraph explaining each one, and finally provide a summary table that will aid in comparison between them.

2. Write a report giving a recommendation for each budget, and justifying your recommendations by comparing them with other options within the price limit.  You should also include a summary table highlighting the differences between the three different options that you have recommended. 

3.  Explaining how you would position multiple instances of that router in the warehouse, and what channels you would have each instance operate on, to ensure complete coverage, appropriately low interference, and minimal total cost.

It defines the protocol that permits the reception & transmission of information at upto 54 Mbps at a shorter range. It follows the OFDM (Orthogonal frequency-division multiplexing) architecture. The most prominent advantage of the deemed protocol is its high carrier frequency which also reduces its overall range citing disadvantage.

802.11b: It data allows transmission & reception at upto 11 Mbps and follows the CKK (complementary code keying), DSSS (Direct sequence spread spectrum) channel architecture. It is a low frequency carrier which has witnessed a mass adoption due to its benefits and at a low cost. However, it experiences high interference.

802.11g: Following the OFDM based channel architecture the protocol is capable of offering transmission & reception of data at a rate of upto 54 Mbps and also offers double range in comparison to its predecessors (802.11a, 802.11b). It is also one of the most adopted protocols because of high data rate and long range.

802.11n: The deemed technology has adopted MIMO (multiple input multiple output antennas). It is capable of offering at or over 600 Mbps data transmission & reception rate. Since, 2007, the discussed technology has emerged as one of the most prominent choice for the organisations because of the high data transmission rate.

802.11ac: The deemed protocol is the path pavers for the future protocols that offers wider channel options (80 or 160 MHz). it also offers a high data transmission rate of upto 6Gbps and it supports an advanced format of MU MIMO (Multi user multiple input multiple output). Vendors are calling it “Wave 2” devices that supports four spatial streams & 160 MHz channels.

802.11ad: The deemed protocol, defines the most disruptive physical layer of 802.11 network and the operation takes place under the 60 GHz mm (millimetre) wave spectrum. The architecture of the channel followed by the discussed protocol is OFDM and the most prominent challenge offered by the discussed protocol is its range that is limited to upto 10 m only. The transmit power off the technology is very low in comparison to other counterparts.

Recommendations for Routers under $100

802.11af: The deemed protocol is known by multiple other names such as the “Super Wi-Fi” & “White-Fi” and follows a frequency band that can extend from 54 MHz to 790 MHz. The channel architecture for the discussed protocol is based over SC OFDM and capable of offering data transmission range of upto 26.7 Mbps and transmission range of 1 Km.

802.11ah: One of the most widely adopted wifi protocol is the discussed protocol. It is operational in a frequency band of upto 900 MHz and the transmission rate of upto 40 Mbps. The channel architecture is SC OFDM and the range can extend upto 1 Km. It adopted due to extended range and the power consumption of the technology is also very low.

802.11ax: It can be considered as the successor of the 802.11ac and has enhanced the capabilities of the latter. Like its predecessor it works on the OFDM and offers a range of upto 1000 ft. Of all the discussed technology it is the most disruptive of them and the full potential of the protocol is still to be measured in the commercial market.

MIMO: Multiple input multiple output is the technology associated with the antennas in the wireless technological frameworks that uses multiple antennas at the source end & the receiver end as well. It minimises the errors and the data speed as well.

The following table has summarised the nature of the 802.11 technologies and presented it in it:

The router recommended to the for around $100 is the TP-Link Wireless Router AC1900 Smart WiFi Dual-Band Gigabit (Archer C9). The router is very efficient within a small complex and would support more than 12 devices in the network and the speed provided for the network is around 1750 mbps. The router consists of advanced feature that helps in obtaining the free application of the individuals working on the router. The system requirement to support the router in the network are Microsoft Windows 7, 8, 10, Vista, XP, 2000, Mac OS, UNIX, or Linux, Microsoft Internet Explorer 5.0, Firefox 2.0, Safari 1.4, or Google Chrome 11.0 browsers or higher. The router is to be placed on the lower level of the warehouse. This would provide the networking access to the staffs form all the corner of the warehouse. The warehouse also need additional access hence; it is recommended that switches are used with the router that would help in spreading the network to the whole warehouse. The switch that is to be used is a 24 port switch. The recommended switch for the network is the Cisco 24 port Gigabit Switch (10/100/1000). This help the network is providing access to all the nodes within the warehouse. The switch provides 24 ports that provides 10, 100 and 1000 mbps speeds for the network and also the Weighted Round Robin (WRR) queuing which helps the network during congestions. Additionally, the standard provided for the router are IEEE 802.3, IEEE 802.3u, IEEE 802.3z, IEEE 802.3ab, IEEE 802.1p, IEEE 802.3x, IEEE 802.3az. Each switch port independently sets itself for the optimal speed and determines whether to run in half- or full-duplex mode automatically. The switch supports the network speeds of around 10 mbps, 100 mbps and 1 Gbps. Hence there would be no confusion within the warehouse that would be taking place in between the staffs that so anyone can connect to any cable they want to. The switches would be able to deliver the performance that the organization wants to perform very efficiently. It supports up Gigabit Ethernet speeds, unlocking a new level of capacity and performance in your business network and letting you transfer large files in seconds. Along with the router the NETGEAR CM500-1AZNAS (16x4) DOCSIS 3.0 Cable Modem, Max download speeds of 686Mbps, certified for Xfinity from Comcast, Spectrum, Cox, Cablevision & more product should also be used. The DOVCSIS 3.0 of the device provided up to 680 mbps of speed and the alternate version of DOVCSIS 3.0 of the device provided up to 960 mbps of speed. This would help the internet connection into the network. The product Support Cable Internet Service plans up to 200 Mbps. Separate router required for Wi-Fi. 16x4 channel bonding. The dev ice would also help in making the firewall configurations in the router. The firewall configurations for the router are very important and the organization has already mentioned that the employees in the network should not be able perform tasks other than the official tasks that are required. The setting in the router are to be set to use Opendns, if the internet service provider does not provide a strong enough / limited control. Additionally, the internet service provider can be also be asked to provide the network with the firewall facilities and this would help the access control in the network however the this would be very unconvincing for the staffs within the warehouse. The process is very easy. The user has to make a free account with opendns & use their parental control customise the options It should also be ensured that the web stats / logging are enabled. Thus to monitor what sites are being viewed. The standard accounts are created for the employees and the administrator account would be created for the admin. So the employees Can’t change settings or add programs that may be malicious and also they can’t change the DNS settings on the computer / laptop & thus side step the router DNS settings. The admin should also periodically login in to opendns online & check web usage to spot any patterns of activity, whether the employees are trying to access restricted sites and then have a general chat about the web and avoiding detrimental habits.
