Today's mobile broadband services use networks primarily designed for making phone calls (often referred to as 3G or Third Generation). However, XOHM plans to build the first nationwide network using WiMAX (a Fourth Generation, 4G technology).

Our WiMAX network is being developed from the ground up specifically for internet data rather than just voice to deliver a better online experience for email, web browsing, videos or music downloads.

Comparisons and confusion between WiMAX and Wi-Fi are frequent, possibly because both begin with the same two letters, are based upon IEEE standards beginning with "802.", and are related to wireless connectivity and Internet access. However, the two standards are aimed at different applications.

• WiMAX is a long-range system, covering many miles/kilometers that typically uses licensed spectrum (although it is possible to use unlicensed spectrum) to deliver a point-to-point connection to the Internet from an ISP to an end user. Different 802.16 standards provide different types of access, from mobile (similar to a cell phone) to fixed (an alternative to wired access, where the end user's wireless termination point is fixed in location.)
• Wi-Fi is generally a shorter range system, typically tens of yards/meters, though its range can be extended to over a kilometer using directional antennas[10]. Wi-Fi uses unlicensed spectrum to provide access to a network. Typically Wi-Fi is used by an end user to access his/her own network, which may or may not be connected to the Internet. If WiMAX provides services analogous to a cell phone, Wi-Fi is similar to a cordless phone.
• WiMAX and Wi-Fi have quite different Quality of Service (QoS) mechanisms. WiMAX uses a mechanism based on connections between the Base Station and the user device. Each connection is based on specific scheduling algorithms, which means that QoS parameters can be guaranteed for each flow. Wi-Fi has introduced a QoS mechanism similar to fixed Ethernet, where packets can receive different priorities based on their tags. This means that QoS is relative between packets/flows, as opposed to guaranteed. # WiMAX is highly scalable from what are called "femto"-scale remote stations to multi-sector 'maxi' scale base that handle complex tasks of management and mobile handoff functions and include MIMO-AAS smart antenna subsystems.

Due to the ease and low cost with which Wi-Fi can be deployed, it is sometimes used to provide Internet access to third parties within a single room or building available to the provider, often informally, and sometimes as part of a business relationship. For example, many coffee shops, hotels, and transportation hubs contain Wi-Fi access points providing access to the Internet for customers.

The XOHM WiMAX network combines the best of broadband and mobility. Now, you get the same broadband internet experience you get at home anywhere in the XOHM coverage area... even On-the-go. Think of it as the mobile version of basic DSL or Cable internet service.
