Delivering Gigabit tier service with wireless using 60 Ghz or 6 Ghz band

In the recent order regarding the RDOF auction the FCC said “While an applicant will be permitted to select the Gigabit performance tier in its application if it intends to use fixed wireless or DSL technologies for meeting its Auction 904 public interest obligations, such applicants face a high burden to persuade Commission staff that they are reasonably capable of meeting the public interest obligations in rural areas and thus qualified to bid for the Gigabit performance tier.

This paper from 竞博jbo官网登录 is designed to assist prospective bidders to persuade the Commission staff that the Gigabit tier is most certainly capable and that many of our customers are qualified and currently delivering a Gigabit service.

60 GHz毫米波

 (V-Band) fixed wireless technology that makes it easy to meet the surging demand for bandwidth in urban locations. Service providers now have access to multi-gigabit speeds in multiple configurations, including business and residential last mile access and backhaul for wireless MicroPoP access. 获得脸谱网 Terragraph网格技术认证, these 60 GHz solutions make it easy to provide efficient multi-gigabit speeds in the heart of any city.

6 GHz

The recently available 6GHz of spectrum in standard power mode has opened up the possibility to offer Gigabit speeds via fixed outdoor wireless broadband equipment and in fact to some extent in the current 5GHz spectrum. 竞博jbo官网登录 is currently developing both a 5GHz and 6GHz range of fixed wireless broadband equipment capable of offering greater than 1Gbps service to customers throughout the fixed wireless community. This new technology leveraging the 6GHz spectrum is based on chipsets and capabilities derived from the 802.11 ax技术.

在信道宽度为160MHz的情况下执行的能力, achieving maximum modulations of 1024QAM or 4096 QAM allows the fixed wireless equipment to confidently offer gigabit speeds to a wide swath of rural customers. Based on Cambium Network’s tests and analysis the following performance numbers can be achieved confidently via the use of 160MHz spectrum in the 6GHz spectrum in conjunction with the hardware based on AX technology.

Following an EIRP of 36dBm at the AP and SM antenna of 25dBi in low interference scenarios, 操作员可以提供

1.6个千兆比特每秒 DL速度水平1024 QAM调制在距离1.3英里.

In the same distance, uplink of approximately 500Mbps can be achieved. 此外, assuming rural deployment and very low interference that do not necessarily require synchronization and a fixed DL/UL ratio, DL和UL性能可以同时为1.6个千兆比特每秒.

竞博jbo官网登录 is also planning to offer a platform that can achieve 4096 QAM. 随着本平台的使用,在低干扰环境下,在 .6 mile distances, DL speeds of 2Mbps can be achieved and uplink speeds of 576Mbps.

Below chart offers a visual on distances that can be achieved against interference levels.

The table below highlights the key technology attributes that allows for the 802.11ax based solutions to achieve Gbps performance in fixed wireless deployments.

Additionally, the below table for 6 GHz rates highlights the various configurations under 802.11ax based solutions for fixed wireless where greater than 1Gbps DL and 500Mbps UL performance can be offered.

在上表中-
MCS -表示“调制和编码方案”
R -编码速率
Nbpscs -每个载波的编码位数
Nsd -数据子载波数
Ncbps -每个OFDM符号的编码位数
Ndbps -每个OFDM符号的数据位数

Note: For UL TDD, the estimations here are based on a pure GPS sync’d TDD frame structure. 对于不需要GPS同步的情况,例如低干扰, 低密度部署, 一个灵活的调度器可以在DL和UL中实现~2Mbps.

总之, the 6GHz spectrum combined with 竞博jbo官网登录 solution leveraging operation in contiguous 160MHz spectrum, 支持1024/4096QAM, OFDMA效率11AX标准, operators can confidently offer greater than 1Gbps service in the DL and 500Mbps of service in the uplink.
