Overview |
Computer and telephone networks need “connectivity” to communicate within and among each other.
At present, there are 2 methods of accomplishing this: |
- wired or "fixed"
- wireless
|
Which to use? When wires don't reach, or the cost of cabling is excessive, wireless may be the option. Whether it’s wired or wireless, CompuTel can do the job!
The following is an overview of each.
Wired networks - generally referred to as Ethernet networks, have structured cabling systems of CAT 5, CAT 5E, or CAT 6 cables built into the ceilings, walls and floors. Alternatively, especially for cable runs longer than 300 feet, fiber optic cables are used. Fiber to the user location is not generally cost effective yet. |

| Advantages of wired networks include: |
- Speed – generally faster than wireless networks. Speed can depend on the Network Interface Card (NIC) used, the speed of the hub or switch (10/100 or 1000 Mbps), and the type of cable used
- Reliability – generally not prone to interference and fluctuations in available bandwidth speed as wireless networks can be
- Security – wired networks are very secure. Due to the physical cables carrying the traffic, no one can monitor your traffic or use your network unless they are physically connected to it. Routers with integrated firewalls prevent intruders from accessing your network.
|
| Wireless networks – generally used to reduce initial costs or where cables can’t be utilized effectively or efficiently and to provide flexibility of movement throughout the facility. |
| |
| Advantages of wireless networks include: |
- Flexibility – provide users freedom to work anywhere within the location without the need to “plug-in” to a network cable outlet
- Cost – wired networks (structure Ethernet cabling) is clearly more expensive. Setting up a wireless network can cost significantly less as the only items to purchase are the wireless “antennas” themselves
- Appearance & safety – wired locations can detract from the appearance of an office or home, especially if the cables can’t be placed in walls or ceilings and need to be exposed or placed in raceways or power poles. Additionally, exposed or unsightly cables from wall or floor outlets to the device needing connectivity can create unsafe conditions.
- Security – correctly setup, wireless networks using the numerous security protocols available with wireless networking devices can be quit secure. They can be password protected and limited to designated devices using MAC addresses. Firewalls in routers or connected devices can further enhance security, BUT WIRELESS NETWORKS ARE INHERENTLY LESS SECURE THAN WIRED NETWORKS.
