For service providers, the benefits of WiMAX are self-evident if there are users. However, some guidelines are needed to win users. After all, most people just have some simple understanding of WiFi if they just use broadband to access the Internet. Therefore, being able to ask questions and focus on WiMAX has become the key to their successful deployment.
service qualityQoS is the ultimate determinant of today's high-speed bandwidth service technologies, such as VoIP and IP video services, as well as other collaborative-efficient applications. In order to provide QoS, WiMAX providers must ensure low latency.
The simple fact is that WiMAX services have almost no delay through their wireless connections—the process from the base station tower to the receiver is less than 10 milliseconds. Any major delays occur between the forward receiver and the server and end users. Therefore, like all bandwidth services, Qos is responsible for ensuring that these services are handled by the right devices of the enterprise's network devices, and that service providers are required to provide the appropriate technology for residential users – as it does today.
SafetyRecently, Network Security has received sufficient attention, especially for Wifi deployments that lack effective security measures. In addition, WiMAX has been designed to provide effective security to avoid network intrusions and access violations.
As described in the WiMAX standard, WiMAX security is defined in the Privacy sublayer in the MAC layer. Fixed WiMAX (802.16-2004) typically uses X.509 authentication certificates and 56-bit digital encryption systems (DES), while mobile WiMAX (802.16e-2005) uses authentication encryption and Advanced Encryption System (AES) EAP. They all use a private key management mechanism (PKM) to authenticate data transmission between the base station and the user terminal.
reliabilityThe "five nines" of network uptime have become the dominant standard for network providers to describe their network availability and network operation. However, in fact, although cable network providers may have the ability to guarantee such reliability. - This is equivalent to five minutes of downtime in a year. Other factors can lead to significant service relays. In particular, fixed-line services rely on home or business lines, which means a single point of failure - limiting access to multiple lines, which is an expensive proposition. Because it provides a wireless connection to the user's location, WiMAX eliminates potential failures caused by fiber and cable. Technically, these potential threats are not caused by the failure of the provider network. Conversely, by deploying redundant transmitters to cover an area, WiMAX providers can provide network redundancy while expanding their service range with the same device.
In addition, by using only licensed spectrum, service providers can rest assured that they do not compete with other operators' network resources. Moreover, since WiMAX RF is expected to have a lifetime of more than 40 years, WiMAX technology can be sold as an effective disaster recovery solution.
interferenceThis is no secret. Wireless signals are very susceptible to interference. This is the nature of nature. Since the advent of the first wireless device, this has become a feature that wireless service providers must consider. Even now, the old 2.4Hz cordless phones and other home appliances may disrupt wireless signals.
Vendors can use anti-jamming devices, which often need to be managed. Its true meaning is to understand the root causes of interference in the electromagnetic spectrum and to adopt engineering solutions to solve these problems.
