Abstract
Wireless-wireline convergence and cellular wireless deployment can economically accelerate through partial transmission of wireless 4G, 5G (generally 3GPP-standards-compliant), and/or Wi-Fi 6 baseband signals on the billions of copper phone, Ethernet, coaxial cable, and other wireline connections. This article poses such a Cellular Subscriber Lines (CSL) re-use architecture and investigates large bandwidth-efficiency gains, as well as the consequent cost-efficiency improvement that accrues for CSL’s deployment infrastructure. In-home wireless signals’ seamless distribution partially over copper links can achieve good data-rate-versus-distance profile. Results here also expand to Wi-Fi (possibly with MIMO use) on Ethernet multi-pair cables, finding very large gains over existing enterprise mesh (ad-hoc or otherwise) approaches.

C ELLULAR wireless standards’ advance1 through the last 15 years’ 3GPP releases to current (5G) releases has leveraged well the multicarrier modulation methods deployed in earlier DSL networks
If the downlink group delay estimate is longer than the half-round-trip delay, this buffer control subtracts this amount from the Δ value for the T counter; correspondingly, if the delay is shorter, the controller adds this amount to Δ
The Cellular Subscriber Lines (CSL) system might even perform better on the wireline link than the DSL system would have
Summary
C ELLULAR wireless standards’ advance through the last 15 years’ 3GPP releases to current (5G) releases has leveraged well the multicarrier modulation methods deployed in earlier DSL networks. Several different situations that bond multiple wireless/wireline paths become possible in Section III’s proposed architectures; these circumvent the creative switching concepts of [6] through exploitation of the current wireless MU-MIMO and/or MIMO capabilities, introducing a higher-performing CSL-RF+ that uses different (and this article argues optimal) mid-MIMO precoders, as an alternative to those discussed in [10] Some of these new methods readily allow large performance. This dashed-line connection may occur if there is a separate wireless link between the existing cell-tower position and the north end of the twisted-pair cables.
