Difference Between Fiber Internet VS Wireless Internet

In the world of the internet, the term fiber optic and wireless may be familiar to your ears. Both are technologies used to access the internet, but each has its advantages and disadvantages.

Before discussing further, there are not many reviews about fiber optic and wireless to remind you of these two matters.

Fiber Optic is a technology that utilizes glass or plastic thread to deliver data. Glass or plastic fibers can transmit messages modulated into light waves.

Fiber optics is considered to have less profit than traditional communication lines that still use metal. One of them, fiber optic cable has far more bandwidth than metal cables.

This means that fiber optic cables can carry fewer data while wireless is a technology that uses electromagnetic waves (radio and infrared) as a substitute for cable media (physical facilities). At least, three matters separate wireless internet and internet fiber.

Here are 3 differences in fiber optic and wireless internet explanation:

1. Installation and maintenance costs.

Because wireless does not have a few physical facilities such as fiber optics, the cost of installing and maintaining wireless will be cheaper.

Wireless only requires the cost of installing stations and equipment lent to users. Wireless also does not need individual costs for maintenance because there is no physical infrastructure.

While in fiber optics, the costs for installation and maintenance will be much more expensive.

Apart from having to prepare a path between two points, fiber optics must install cables and transmission equipment. Also, Fiber optics is also more susceptible to problems because this type uses physical wires.

2. Repair

Wireless repair is equivalent to the process of expediting information from one point to another using the microwave radio spectrum. The information is then transmitted from one central place to the receiving antenna.

One problem that is often an issue is because the process requires a line-of-sight connection, but the problem in this matter is relatively small and wants to be installed more easily. That said, the repair process is 50% faster than fiber optic.

When negotiating fiber optics, the speed of data sent is not as fast as the speed of light, not even at all. Remote light moves much faster than information transmitted through metal wires.

Also, the times needed to receive a command and send an answer (latency) to the optical fiber are higher than wireless. In comparison, microwave signals on wireless have latencies of 5.4 microseconds, while light on fiber optics moves at 8.01 microseconds per mile.

3. Security

Despite losing two points in terms of costs of installation and maintenance and repairs, fiber optics is superior in security matters. Fiber security is more tested because the network signal is not sent through the air, making it avoid the threat of tapping or illegal connections.

Choosing between fiber or wireless internet is indeed not easy, after all when we know that each has advantages and disadvantages.

But actually, knowing the strengths and weaknesses of each can help you choose which one is most suitable for your company’s situation and needs.

A variety of common network problems

Computer network problems can cause network software problems and disruptions to business continuity. The scale of this disturbance can vary depending on the source of the disturbance and the consequences it has on your infrastructure network. Network problems can cause downtime (how come the language …?) And this downtime can vary depending on how well you plan planning contingencies. Good management of your network system files can help you minimize downtime and make it easier for you to troubleshoot your network problems.

Various types of network problems

There are not a few types of network problems that can cause disruption to a computer, disruption of local networks, to disruptions to the global network of business connections in your corporate.

Network problems due to network cable failure

This is a common network problem that you encounter with the impact of network cable breakdowns that can affect the performance of a computer on the network because of the breakup of your patch cable because it was bitten by a mouse; dominant network problems in one building block because the cable breaks between switches (uplink cable); or even dominant in the majority of computers in your LAN network due to failure of backbone cable.

Impact of network collapse

The dominant network problem on a computer may not be a big problem except that of the general’s computer or your director. But the dominant network problems in your LAN network in bulk or even globally dominant in your corporate business can create a cold sweat. In a large-scale network infrastructure system, a redundancy system must be implemented. So that if a failure occurs in one network path it will not result in network failure in long periods.

Enable STP switch

In a residential multi switch network, the Spanning Tree Protocol (STP) must be enabled and tuned manually. STP is a service that allows the switch-2 network and bridge-2 of your LAN to be connected to each other in a redundant manner with a mechanism that can prevent bridging loops. The bridging loop is a data packet that is circling in the network looking for addresses to exhaustion and the end of koid. This bridging loop can cause your network traffic to crash or be called broadcast storm.

Network problems due to network device failure

The scale of the disruption of the impact of network device failures can also vary, from merely a computer because of the failure of the NIC – LAN card; number of computers due to switch failure; or even wide-scale causes of failure on central switches that connect server networks. For lan card failures between computers it can be replaced with your backup network card.

Link redundancy

So what if the network failure impacts damage to the switch? Your design regarding network redundancy will be very helpful in securing your network failure. The need for load balancing and redundancy must be assessed for every need according to the use of redundancy links; router device; switches and multi-homed hosts that have critical properties. The purpose of this redundancy system is to ensure the availability of services where there is no single point of failure.

Let’s look at the picture above regarding the system of redundancy.

Switch redundancy; If a problem occurs due to a failure on switch A, Switch B can still be useful for supplying links to the server and also to the two channel switches and links to the WAN. This type of network problem will not affect the server down system.

Router redundancy will create a WAN link backup when problems occur between routers. For example, between routers that connect your frame relay network to other offices, there are still backup links on the other router.

Link redundancy – will backup the link if there is a network problem with the link being disconnected to the server or to the switch.

We can apply this redundancy system to the previous scenario model that connects both the Mining and HR offices with unique two underground Cat5e UTP cables as redundancy links. Make sure that both of these redundancy cables are not connected to the same switch, because if there is a failure on the switch it will be useless.

For internet link redundancy, the router is actually already in the market a little with two or more WAN ports to the point that it doesn’t need two routers. This type of router is often for small medium offices where two WAN ports can failover – failback. So if the main link fails, it will failover to the backup link. Or you can also create two links load balancing, let’s say FVS336G Dual Wan Gigabit SSL VPN Firewall.

Network problems due to system failure

Although system failure is not the impact of network infrastructure failure, your users will still call you with the following questions: “Hello Agus … is there a network problem? I can’t access my email … or something like this “I can’t access the internet … or even a question from a radio operator” Hello Agus … how come I can’t access the folder President Director … why is that? ”

System failure can be caused by a problem with your DHCP server so that clients do not accept an IP address. Or it could be because there is a problem with your Directory Services system so that clients cannot log on to the network. Or it could be because there is a problem with registering names in your DNS system.

Network problems due to the spread of the virus

This type is also a network problem that is not due to physical network infrastructure failure, but your network system will be flooded with traffic from the influence of viruses that attack the system server and infect all computers in your network. The performance of your network system will be the slowest even to say collapsed. What you can do with this virus attack is to implement best practice security policy, your system defense must be very immune.

All kinds of network problems, you as a network and system administrator must be able to solve the problem. It doesn’t matter whether the problem is the failure of your network device; or your computer system problems; or an intruder that attacks your system infrastructure system. A good redundancy network design and a good management system is an obligation on a network scale that has a broad and complex nature.
