The History Of The Mobile Broadband Technology

Published Date: 02 Nov 2017

Mobile broadband technology is rapidly becoming a tangible. Today's internet generation has used to a technologically-driven world that wherever they go will be offers wireless broadband access. Three wireless broadband platforms wirelessly deliver information to the technically-minded individuals. WiFi, WiMax, and WiBro offer organization and individuals the ability to unplug from the work and grid anytime at anywhere.

WiFi Broadband

WiFi is reasonably easy and inexpensive to implement that allows fast wireless-networking. WiFi allows consumers wireless internet access within an effective distance of 10 to 50 meters.

WiFi uses wireless routers or stationary wireless hotspots to access the internet. These wireless routers and hotspots depend on a hard-wire connection to the internet. Hotspots are a key component to WiFi and if without access to a hotspot, the internet connection cannot be established. In order to utilize specific hotspot’s internet access, a WiFi user must be in range of a particular hotspots; however, user must join the new hotspot or access the new WiFi signal by entering the security codes if any when he/she moves from one hotspot to another.

There are two security standards in WiFi which is WPA and WEP, which allow data to be securely transmitted; however, data is transmitted with low-level security protection.

Encrypted data will still be able to decipher although WiFi utilizes WPA and WPA2 security protocol.

Individuals and businesses of all sizes use WiFi networks due to Internet Access and low cost wireless LANs. The cost-saving advantage of WiFi makes it very cost effective; however, all users must connect to the hotspot in order to share the connection, hence it’s limited. Thus, connectivity speeds are dependent to the data transmission of each user and number of users.

WiFi does not allow the user to be mobile and WiFi access distance is quite low, moving at extremely low speeds. WiFi is just simply plug-n-play, hence it’s does not require an extensive amount of training. Most people possess some knowledge about maintaining and setting up a WiFi device. Instruction manual will be provide to purchaser of a WiFi device at the time of purchase. A majority of the companies distributing WiFi devices offer free technical support if there is necessary. The utilization of WiFi for larger firms will involve a department or consultant who maintains and establishes a WiFi broadband system.

WiMax

WiMax stands for Worldwide Interoperability for Microwave Access. WiMax known as the Air Interface for Fixed Broadband Wireless Access Systems is a popular term for IEEE Standard 802.16. WiMax can have a wireless range of up to 31 miles and it’s allows for wireless access in areas where broadband wireless access does not exist. WiMax allows direct access to the broadband access or internet through inter-connected access points, which create a large scale network.

WiMax’s objective is to buildings, interconnect houses or even hot spots to relay communication between them and with the remainder of the networks which is a metropolitan technology. In order to obtain WiMax wireless broadband service, a user must establish an account with a WiMax service provider. WiMax is unlike WiFi, it wills automatic change when a WiMax user leaves the range of one antenna and enters the range of a new antenna.

WiMax utilizes the 802.16 specification, which provides quality of service features and robust security that support video and voice. It utilizes RAS and triple-DES security protocol to protect data transmissions. This high-level security protocol provides an extremely high level of data protection and encryption.

WiMax is designed to optimal performance in all kinds of propagation environments and to even provide robust performances in transmissions, difficult cases and to reduce multipath effects result from the reflections. WiMax has a range of up to 30 miles, but is heavily dependent upon special antennae, which allow the transmission and reception of data. The advantage of WiMax technology is mobility. WiMax cannot maintain a broadband connection while moving at medium to high speeds while maintaining an internet signal.

WiMax requires organizations and individuals to become familiar with the emerging

technology. The necessary training cannot be determined at this time; although, with each new technology comes a learning curve. Knowledge about WiMax technology, for the most part, will depend on the device. Laptop and handheld device will be plug-n play. It will require greater expertise while setting a WiMax radio antenna for a large organization.

WiBro

WiBro is commonly known as the South Korean cousin of WiMax. WiBro is a high-speed technology that is comparable with WiMax. WiBro gets users online wirelessly even in vehicles moving at speeds of up to 75 mpg. WiBro has the ability to provide city-wide service. In South Korea, WiBro is the wireless broadband standard.

The WiBro technology operates in a similar fashion to WiMax, with a range of up to 0.5 miles. WiBro technology can work with devices such as handhelds and laptops, which are traveling up to 35 mph. WiBro is quite mobile and can be accessed while the user travels from one location to another. WiBro allows multiple users to connect to each signal-transmitting tower. The user must have the integrated systems architecture to communicate on the WiBro bandwidth to connect to WiBro tower. When a WiBro user leaves the transmission range of one WiBro antenna for another WiBro antenna, the change is unnoticeable and automatic.

WiBro utilizes hyper-encryption technology that allows the mobile device to share k-specific information with the WiBro radio access station. This type of data encryption provides a random encryption string to the recipient and the broadcaster, which creates a one-time communication environment, which provides high level communication protocol security.

Mobility is the greatest asset of WiBro. WiBro provides accessibility at anytime and anywhere. Users can free from the confounds of wired broadband technology with using WiBro broadband technology. WiBro has the ability to stream data, voice, and video to any WiBro-enables device within the WiBro network. WiBro does not have the provide the same performance as hard-wired connectivity and WiBro has a very limited data transmission range.

WiBro technology requires an organizations and individuals to acquire little technical knowledge. WiBro is also plug-n-play technology. Many WiBro devices work right out of the box and do not require any advance technological knowledge. WiBro merely offers mobility, but WiBro speeds compare with fast WiFi. Large WiBro networks are require expertise and complicated.

DDNS known as Dynamic Domain Name System is a method of updating, in real time, a DNS known as Domain Name System to point to a changing IP address on the Internet. This is used to provide a persistent domain name for a resource that may change location on the network.

Users are able to host their own websites, IRC / chat servers and other such services, even mail servers with using Dynamic DNS because users that do not have statically assigned IP addresses. Unfortunately hosting DNS with a dynamic IP address is not possible and having Dynamic DNS services to your IP address still cannot help with that as DNS servers are accessible not via an FQDN and via their IP address .

Users with static IP addresses are always better off not using DynamicDNS, instead they should configure direct DNS services to point to their address. Dynamic DNS requires a low threshold of DNS cache expiry and a large amount of polling in order to recover from changes to the underlying IP address.

Microsoft's development of the Active Directory integrated (ADI) primary DNS zone has some incredible benefits such as built-in performance, recovery and scalability. The Active Directory-integrated zones are replicated and stored on any new domain controllers automatically when Active Directory and DNS are integrated. Synchronization takes place automatically when new domain controllers are deployed. In an ADI primary zone, rather than keeping the old zone file on a disk, the DNS records are stored in the AD, and Active Directory replication is used rather than the old problematic zone transfer. If all DNS servers were to die or become inaccessible, you could simply install DNS on any DC known as domain controller in the domain. The records would be automatically populated and your DNS server would be up without the messy import/export tasks of standard DNS zone files.
