Via LTE Evolution technology, WTTx can provide fiber-like speed broadband access service. Using CPE as a smart home router, wireless operators can not only offer MBB service, but also provide broadband access to smartphone, laptop, fixed phone, TV and so on. Compared to FTTx, there is no need to spend lots of time for engineering deployment, just take CPE and SIM card home, you can start WTTx service in 1 minute. Moreover, there is no need for last mile rental fee, WTTx can help broadband operators to reduce 2 years ROI time. Due to its wireless access method, WTTx can not only provide services in urban, but also for rural, desert, islands and such places that it is not easy for fix network.
WTTx means fast deployment broadband for last-mile, without digging trenches and installing cables underground, this significantly features can shortening the TTM
WTTx can reuses resources of existing GSM & UMTS networks and can be used to identify potential broadband users to prevent investment risks for operators
FTTx networks are complex and take a long time to deploy and launch. WTTx and FTTx mixed construction can speeds up broadband deployment and shorten ROI 3 years
Suburban / rural need broadband service and old urban where DSL experience is poor need acceleration, huge market makes double-digit growth
WTTx UEs are stationary. Idle capacity of the existing MBB network is used to develop WTTx services and then on-demand capacity expansion is performed. Global insights show that 60% of broadband users are served by only 30% of sites. In densely populated areas, capacity expansion can be performed in a single attempt for any given spectrums at any given large-capacity massive MIMO site to improve its capacity by ten fold. This facilitates network development over the next three to five years.
The SPID-based UE priority solution defined in 3GPP specifications can easily guarantee user experience. Based on the features of FWA, Huawei uses different SPIDs to define scheduling priorities for MBB and WTTx UEs. This helps to control the PRBs used by WTTx UEs depending on UE scheduling priorities or dynamically during peak hours to ensure that MBB experience is not affected.
Level 1: Service provisioning management and control using the WTTx Suite enables operators to fully manage and control capacity and experience to ensure that all provisioned services meet the product quality requirements (package speeds). Services are not provided to low-signal-quality UEs. This is because the spectral efficiency of 5% of low-signal-quality UEs is only about 1/10 of the average. If services are not provided to such UEs, the average spectral efficiency improves by more than 50%. Low-quality CPEs can be quickly identified and are not deployed. This is because the performance of these knockoff CPEs (powered by knockoff chipsets) is poor, lowering capacity by more than 30%.
FWA terminal-pipe coordination: The capacity of massive MIMO and outdoor CPEs is ten times that of a traditional 2T2R system. For given spectrums, the effective capacity in a traditional 20 MHz LTE TDD cell is only about 34 Mbit/s, while massive MIMO, high-performance 4R/8R CPEs, FWA optimization, and service provisioning management and control can achieve 350 Mbit/s or higher, improving cell capacity by over ten times.
A differentiated business model divides users into premium, normal, and entry-level categories. The speeds of premium users are guaranteed and a basic guarantee is provided to normal users, while the speeds of entry-level users are not guaranteed. This model facilitates experience monetization. Entry-level prepaid users can make full use of network resources during off-peak hours to maximize the value of the network.
An E2E speed guarantee solution ensures user experience based on the SLA service level during peak hours. Service provisioning management and control of the WTTx Suite recommends guaranteed speed packages. High-performance 4R or 8R CPEs are recommended for these users based on the signal quality and capacity. Normal postpaid users: Service provisioning management and control of the WTTx Suite recommends the maximum package speeds. Basic experience of these users is guaranteed during peak hours. Indoor or outdoor CPEs are recommended for these users based on the signal quality and capacity. Entry-level prepaid users: Service provisioning for these users is not controlled. Overbooking does not guarantee the experience of these users. The speeds of these users are restricted during peak hours. Entry-level indoor CPEs or MiFi is recommended.
