Introduction
 According to Cisco (2014), Wi-Fi (a wireless technology) will surpass wired
connection in 2018. This outcome will be facilitated by the enormous benefits the
technology offers.
 When one considers wireless technologies in general, the conveniences of time and
location come to mind.
 In essence, wireless technology will represent any method/technique that is used to
transfer power or information using free space medium i.e. no physical mediums or
connection are used.
 Technologies such as WLAN (wireless Local area network), Bluetooth and satellite
are at the forefront of communication today which necessitates their advancement.
 Now, this presentation tries to highlight these advancements by outlining the recent
advances in the field of wireless technology.
 Moreover, the document also specifies their strengths and weaknesses based on
their applications.

WiMAX (Worldwide Interoperability for
Microwave Access)
 An advancement in the field of broadband wireless connections, which promises to deliver
services to both commercial and residential customers using economical techniques.
 Technically, WiMAX is a wireless equivalent of the Ethernet industrial standard, that will be
an alternative to wired technologies such as Modems, DSL and leased lines.
 In terms of operation, it is set to offer capacities of around 40 Mbps, which is enough to
support operations requiring T-1 speed connections.
Strengths:
• It can provide high bandwidth solutions (>10Mbps) while using the existing infrastructure.
• Secondly, it has a wider coverage as compared to other wireless connections.
• It also can satisfy a wide range of access needs, from Wi-Fi to DSL and cellular connections.
Weaknesses
• Like any other wireless technology, it’s limited in remote areas (far from transmission).
• Multiple connection degrades its signal quality (Mitchell, 2017)

Bluetooth smart
 Also known as Bluetooth 4.0, Bluetooth smart represents the next generation of the Bluetooth
technology where low power will be used to enable connectivity.
 Bluetooth 4.0, will still operate within the 79 channels of the 2.45 GHz range. However, as
compared to other versions, it’s designed to minimise power consumption.
 This outcome will be satisfied using bit connections where data will be sent as smaller
segments eliminating the need for constant connection (pairing).
 Therefore, the connection between two devices will remain dormant unless data is being
transferred, an intelligent technology that will reduce battery drain and the constant
connection requirement.
Strength
• Minimal power consumption.
• Improved authentication protocols.
• Minimal connection establishment requests.
Weakness
• Bluetooth 4.0 will still be limited to the 30 –feet range (Butler, 2012).

WiGig
 To meet the demands of the customers, Wi-Fi connections will require better protocols to
increase their range and speeds. These requirements might be met by WiGig.
 WiGig is the latest Wi-Fi standard whose theoretical speeds are estimated to be 10 Gbps
at a 60GHz operating range.
 This standard, technically known as 802.11ad, will replace the existing highest standard
that can only deliver connections speeds of 1Gbps at a 40GHz band.
 This outcome will increase the access speeds and distance, which will improve data
communication including the transmission of high definition video.
Strengths
• Improved speeds and distance of operation.
• High data rates.
• Improved communication standards.
Weaknesses
• Its operation band (60GHz) is unable to overcome obstacles such as walls (Badman,
2016).
