Wireless Wide Area Networks (WWAN Technologies)

WWAN Technologies

WWAN Technologies : Wide Area Network (WAN) is the connection of networks to allow more comprehensive file-sharing Connectivity. Within organizations, this includes linking multiple internal websites (usually geographic), while outdoors, the most common use is to enable a connection via an Internet Service Provider (ISP) to the Internet.

Why wireless (WWAN Technologies)?

As technologies, wireless solutions complement and compete with traditional wired solutions. However, there are situations when wireless is the only option and others when it is most profitable, others where it is most convenient, and other cases where it is cheapest inappropriate. Therefore, the following points should consider when planning a wireless Network.

Connectivity models in WWAN Technologies

Wireless Connectivity can be installs in one of two models: where the receiver mounts in position or when the recipient is mobile. There are different solutions within these models and the options that can be applied. For example, a radio link uses for wireless WAN connections provision of data and through technical variations in different speeds, ranges, and frequencies.

Some solutions require a license, and some do not. For example, in the UK, the radio frequency is licensing and licensing is by the Radiocommunication Agency (RA).

Fixed WiFi

Fixed wireless links are set antennas that use different parts of the radio spectrum. Provide data services. Devices of this type require and can have a solid or near line of sight in the 2.4 GHz frequency band with ranges of approx. 50 km. According to the required data rate, the higher the required bandwidth, the lower the capacity. Equipment Operation on different frequency bands can offer different bandwidths and ranges Combinations. The range can also influence the choice of antenna optimized for “Spread” to cover a large area or “Distance” to cover a more extensive coverage.

The equipment itself operates either point to point or point to point. The issue to Point Solutions, the wireless connection only exists between two locations, whereas with point-to-multipoint. As a result, the dot can manage wireless connections from different places, then concentrate connections for additional Connectivity.

Cellular

Mobile wireless connections can cover various scenarios where receiving equipment is not repaired in position. In other cases, the receiving unit must still match its Location, but in other cases, it uses the same as a wireless LAN to move freely within the detection area of ​​the system.

The two critical solutions are the Use of satellite and cellular technology. The technology is portable but requires a configuration item in each Location to reference the satellite antenna. Wireless satellite links often only work downstream from the satellite towards the receiver and not downstream and upstream. In some cases, it’s upstream. The connection establishes through a standard telephone line or cellular connection.

Mobile telephony presently suffers from bandwidth problems, and only essential services offer data speeds of 9.6 kbps. However, there are improvements to make the technology acceptable for personal computers. Still, in reality, only new generation cellular networks provide sufficient capacity to connect from one network to another – e.g., B. Internet.

Planning problems

If you are considering a wireless implementation or a telecommunications solution, It is essential. Solutions that initially appear cheap or practicable can become expensive or problematic after doing physical and radiological exams. So it is better to approach Situations from a functional rather than a technological perspective, determine what you want to reach, then choose the appropriate technology. So it sees in the WLAN planning.

Where essential issues like “line of sight” need to be addressed at an early stage. Rural Regions can benefit from wireless solutions as an alternative to lengthy and expensive cables or fiber Installation where there is no cable.

Self-implemented solutions

Fixed-line solutions that you have implemented yourself or “Build and Manage Your Own” are attractive due to the cost structure. Most wireless developers have their own devices with a high initial capital purchase, but the ongoing costs are low. Essential considerations for this approach include support and maintenance, licensing, and device lifetime Replacement planning.

Leased solutions

As an alternative to the wired price model, wireless fixed network solutions offer Digital Subscriber Line (DSL), where a monthly fee is paid for a service. The only difference Between these wireless and conventional wired solutions lies in the technology. Data delivers to a wireless receiver rather than a junction box.

Mobile solutions offer location flexibility via telecommunications companies, so predictable annual expenses are standard and common supplemented by call or download charges. These solutions can raise awareness projects in which IT is taken out of the community and not the community that comes into the community HE. In addition, cellular solutions work without reconfiguration, and without portable satellite, devices can be configures correctly in minutes instead of hours.

The wired solutions are leases to a telecommunications company that owns the cable. Devices and offers service with support. However, this brings consistency and predictability, often expensive annual costs.

Capacity issues

Most fixed wireless connectivity options, such as some wired solutions like DSL, suffer Reduced capacity with increased range. Therefore, the ability of the specified solutions to perform functions Requirements are another critical reason to conduct an early-stage investigation. More bandwidth Fixed wireless solutions are generally the same for upload and download.

Mobile services may vary. Mobile-based solutions work the same as fixed-line solutions because they efficiently create circuits with guaranteed capacity. Satellite services are often provided only as a download, which means that the data is received. The key is used, but an alternative must be found to send data or requests to the network.

One solution is to use a regular modem on an upstream telephone line. Even though it is slower, it can be effective because most web uses are further downstream than Upstream traffic. Upstream via satellite uplink is possible but often requires a larger dish and is an expensive service.

Wireless technologies work with a specific overload. For example, on a point-to-point connection at 2.4 GHz with a theoretical 11 Mbit / s, the expected Ethernet equivalent data rate should be approximately 8.5 Mbps.

Radio spectrum problems

All wireless solutions send signals in a specific frequency band called Spectrum. In Great Britain, the Radiocommunication Agency regulates spectrum usage and ensures that the resources available are uses appropriately. As a result, a particular product works on a specific range, but the technologies are often similar—for example, WLAN access via the 2.4 GHz and the 5 GHz band.

Frequency bands are regulated in different ways; some are open to the public without a License, others require a license, or entire tapes are given exclusively and for a limited time.

In some cases, the unlicensed Use of frequencies should still be allowed, depending on the type of service. Unlicensed Spectrum can be challenging to use if too many people are using it at the same time. As a result, there can be bottlenecks and all users suffer from limited services.

There are also concerns about new Bluetooth systems that could interfere with signals. Again, it is because it uses the 2.4 GHz band. These problems relate to fixed wireless solutions as mobile Connectivity rolled into one defined Spectrum that the telecommunications provider manages.

Security concerns

Most research on wireless communications security has focused on Use of cell phones. However, the research results were inconclusive, mainly due to the lack of Proof.

Although there are some similarities between the technologies used in mobile phones and Wireless networks (wwan technologies) on this scale, the main difference in power output, wireless Network devices produce much less power than cell phones and channels.

Some vendors offer guidelines on using the equipment to minimize potential risks. Research in these areas is ongoing. The National Radiological provides current government exposure guidelines Protection Committee.

Conclusion

Wireless networks (wwan technologies) are an evolving technology with a place in the education market with the flexibility and financial models it supports. However, the importance of Planning and measuring before implementation cannot be overstated. With many technologies, it’s best to think of it as part of a complete solution rather than part of a solution.
