WiMAX uses OFDM and smart antennas to improve performance. It provides QoS and improved security. The architecture includes mobile stations, base stations, an access service network gateway for traffic aggregation, and a connectivity service network for internet/network access. WiMAX antennas can be omnidirectional, sectoral, or panel designs. The protocol layers include the control, management, and data planes. OFDMA dynamically allocates bandwidth across frequency channels. While HSPA focuses on cellular mobility and data/voice, WiMAX provides broadband data through a new infrastructure.
Recently Qualcomm announced its 5G (the fifth generation mobile communications) vision. 3GPP is going to finalize the 5G standard by 2018. 5G is scheduled to launch in around early 2020s. Even if it is not determined yet regarding the standard technology details, many researchers expect that 5G will transfer 1000 times more data, and thus, can connect billions of IoT (Internet of Things) devices at the same time. Key candidate technologies that enable 5G to support IoT devices connection are millimeter wave/MIMO (multiple input and multiple output) technology, cloud RAN/network function virtualization (NFV)/ software defined network (SDN), ultra dense network (UDN), low latency network and RSMA (Reservation multiple access)/FDR (full-duplex relaying). Following Qualcomm patents illustrate some examples of the 5G standard technology R&D of Qualcomm.
WiMax offers some advantages over WiFi.WiMax is the real wireless architecture by which the wireless access range can extended to 49.6Kms compared with Wi-Fi 91mts and Bluetooth’s 9mts. WiMax used to provide connectivity to entire cities, and may be incorporated into laptops to give users an added measure of mobility.

WIMAX stands for Worldwide Interoperability for Microwave Access.WiMAX refers to broadband wireless networks that are based on the IEEE 802.16 standard, which ensures compatibility and interoperability between broadband wireless access equipment.
The High Altitude Long Operation (HALO) network is a broadband wireless Metropolitan Area Network (MAN) consisting of HALO aircraft operating at high altitude and carrying an airborne communications network hub, with network elements on the ground.. It will provide broadband services to businesses and to small offices home offices in an area containing a typical large city and its neighboring towns. To each end user, it will offer an unobstructed line of sight and a free-space like channel with short propagation delay, and it will allow the use of low power low-cost user terminals.

EMERGING BROADBAND WIRELESS TECHNOLOGIES: WIFI AND WIMAXcscpconf
Now-a-days there is high demand for broadband mobile services. Traditional high-speed
broadband solutions depend on wired technologies namely digital subscriber line (DSL). Wifi
and Wimax are useful in providing any type of connectivity such as the fixed or portable or
nomadic connectivity without the requirement of LoS (Line of Sight) of the base station. Mobile
Broadband Wireless Network (MBWN) is a flexible and economical solution for remote areas
where wired technology and also terminal mobility cannot be provided. The IEEE Wi-Fi and
Wi-Max/802.16 are the most promising technologies for broadband wireless metropolitan area networks (WMANs) and these are capable of providing high throughput even on long distances with varied QoS. These technologies ensure a wireless network that enables high speed Internet access to residential, small and medium business customers, as well as Internet access for WiFi hot spots and cellular base stations. These offer support to both point-to-multipoint (P2MP) and multipoint-to-multipoint (mesh) nodes and offers high speed data (voice, video) service to the customers. In this paper, we study the issues related to, benefits and deployment of these technologies.

3. IP Based WiMAX Architecture MS- Mobile Stations BS- Base Station (Provides air interface to MS) ASNGW- Layer 2 traffic aggregation point within an ASN CSN- provides connectivity to the Internet, ASP, other public networks, and corporate networks. Wireless Networks Wimax Presentation 3/7/2011
4. WiMAX ANTENNAS Omnidirectional used for point-to-multipoint configurations and main drawback to an omni directional antenna is that its energy is greatly diffused in broad-casting 360 degrees. Sector focuses the beam in a more focused area and offers greater range and throughput with less energy. Panel Panel antennas are usually a flat panel of about one foot square. They can also be a configuration where potentially the WiMAX radio is contained in the square antenna enclosure with a power source of PoE Wireless Networks Wimax Presentation 3/7/2011
5. WiMAX LAYERS The CPS provides functions related to duplexing and channelization, channel access, PDU framing, network entry and initialization Control Plane for admission control, resource control, congestion and load balancing Management Plane for traffic engineering, monitoring Data Plane For Transport of Information. Wireless Networks Wimax Presentation 3/7/2011
6. OFDMA/Dynamic Bandwidth Allocation OFDM divides up the spectrum into Channels and uses an appropriate data rate for the conditions on that Channel. Mobile Wimax(802.16e) uses OFDMA technique that allowsmultiplexing in both time and frequencywherebychannels are divided into groups and users are allocatedslots in time for one or more of thesegroups of channels. Wireless Networks Wimax Presentation 3/7/2011
7. WiMAX and HSPA HSDPA is about mobility and data and voice from a cellular platform, whereas WiMAXis about broadband data to the enterprise and coverage infill. HSDPA does not require any new infrastructure as it only requires a software upgrade. WiMAX, on the other hand needs a whole new infrastructure to be built which will be time consuming and very expensive. Wireless Networks Wimax Presentation 3/7/2011
