A recommended solution for Karaaka is fiber optic connection. Fiber optic networks operate at high speeds of up to gigabits thereby providing considerably high data rates. In addition, fiber optics has the advantage of transmitting signals over long distances unaffected.
Analogue systems provide a host of challenges in transmission and distribution. In analogue implementation, the logical and physical connections are one and the same implying that most connections are point-to-point with each cable representing individual channels. Analogue audio for instance requires copper cables for signals, but these systems offer little flexibility to accommodate system changes. Moving or adding equipment in a location will present significant additional costs. Digital media distribution significantly reduces the implementation by separating the logical and physical connection attributes of AV system. Thus digital networks provide significant cost savings in terms of time and money, while providing better performance than analog distribution (Forouzan).
Digital audio distribution for instance eliminates masses of bulky, heavy, expensive, and inflexible copper wires. Installation is simplified using digital networking, a single light weight; inexpensive CAT5 cable can carry all the required inputs and outputs as digital audio data.
IP over Ethernet is the most deployed approach for networking and presents the best available founding technology for media networking. CAT5 cables, switches, routers and other components used to build such networks are available readily in the market. The following benefits are derived from digital networks:
- Cost savings
- Separate logical and physical connections
- Large bandwidth over a single cable
- Improved video and audio quality- no hum, ground loops and degradation
- Leverage of IT equipment to take advantage of industry developments in functionality, reliability, availability and cost savings
Multiplexing, carrier systems and transmissions
Multiplexing is a phenomenon permitting the transmission of multiple signals across a single data link. In a multiplexed system, n lines share the same bandwidth of one link. This is done because today’s technologies including high-bandwidth media such as optical fiber and terrestrial and satellite microwaves has a bandwidth far in excess of that needed for the average transmission signal. Given that the bandwidth of the link is greater than the bandwidth of the device needs connected to it, a lot of bandwidth is wasted and in order to minimize wastage multiplexed systems are used (Kularatna).
Multiplexing techniques are three in number, frequency division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
FDM is an analog technique applied when the cumulative bandwidth of the signals to be transmitted is less than the bandwidth of the link. FDM is implemented easily in radio and television broadcasting. In cellular telephone systems, a base station needs to assign a carrier frequency to the telephone user.
In wavelength-division multiplexing, a high-data-rate capability of fiber optics is used. WDM is similar to FDM except that the optical signals are transmitted through fiber-optic channels. Finally, Time-Division Multiplexing is a digital process allowing several connections to share the high bandwidth of a link. Instead of sharing the portion of the link as in FDM , time is shared. Time is shared rather than frequency (Forouzan).
Wireless technology implemented
In the context of Karaaka, a Wi-Fi wireless connection is advised. Wi-Fi is a wireless technology under the IEEE 802.11 standard. It is by far the most widespread wireless technology. It is familiar in wireless devices, as well as in TV sets, video accessories and home devices. It is also suitable for deployment in many industrial applications. The technology has been around since 1990s and offers improved data speeds of up to 11-Mbps in the 2.4GHz band while the new 802.11g and 802.11n standards using OFDM have increased data speeds of up to 54 and 300 Mbps simultaneously.
Satellite based service
Satellite connectivity uses two methods of connections; single-way satellite and two-way satellite systems. Compression mechanism is ineffective because it sends data in a two-way technique thereby impacting on the IP multicasting technology. Some satellite technologies uses dial-up modems for uploading. This signifies that unlimited speeds anticipated for business operations are limited. Likewise, signal strength is affected by environmental factors such as rain, terrain and winds. Satellite based services as compared to other communication techniques are limited in terms of latency. This is because; the signal is traversing between the satellite and the communicating media. This it is not a top performer in terms of latency for mission critical business processes such as video conferencing.
Impacts of cellular service to business development
Cellular devices communicate through wireless communication. Because of their mobility, they require a communication medium which is flexible and available to keep them connected. In the business spectrum cellular devices have improved the way business processes are executed. Internet connectivity has enabled employees to work from home from the comfort of their couch or while in transit. A remote user no longer needs to travel to the office in order to present his business report. Through cellular devices such as Smartphone’s’ and tablets and via wireless communication, they can submit reports wherever they are located.
Through cellular devices and wireless communication, interaction between business and their clients is enhanced. Business transactions such as booking and reservation, advertising, file transfer among others can be done remotely and with ease.
Finally, wireless communication has enabled collaborative techniques. A business does not have to call for physical boardroom meetings. Members can just connect to them virtually through mobile devices. This saves times and eliminates additional costs cost of setting up meetings.
