LTE Band 32 1500Mhz Introduction

Band 32 (1500 L-band) is an LTE operating frequency Band. LTE is designed to work across a number of frequency bands – E-UTRA operating bands- currently ranging from 450 MHz up to 3.8GHz. The available bandwidths are also flexible starting with 1.4 MHz up to 20 MHz with Carrier Aggregation allowing use of wider multiples.

LTE Band 32: Downlink-only!
The 1500 MHz range (L band) is, as far as I know, provided by the BNetzA as a pure downlink spectrum (Supplemental Downlink, SDL), as an uplink is thus missing, so it must be combined with FDD or TDD in another band in order to have an uplink.
Band 32 is an FDD LTE band, purely theoretically, the frequency range could, of course, also be specified as a TDD band, so that downlink and uplink in the same range would have been possible. For use in Germany and / or Europe, the use as a downlink supplement with FDD LTE appears to be just right, as the operators almost always rely on FDD LTE.

Operators Use LTE Band 32 (1500Mhz)
The band 32 is now used for German network operators. In 2015 Vodafone and Deutsche Telekom acquired an auction of the Federal Network Agency in the area around 1500 MHz. Shortly thereafter, the 3GPP officially specified the spectrum as spectrum 32. This makes it possible for providers to offer mobile services over this frequency range, for example over 4G / LTE or later also over 5G.

LTE Band 32 is defined as for use as follows:
Frequency Range: 1452 – 1492MHz
Width of Band: 40MHz
Channel Plan FDD/TDD (Time Division Duplex)

LTE 1500 at Vodafone and Telekom
As we now know, band 32 is intended exclusively to supplement the downlink. Both the Telekom and Vodafone have won four blocks of 5 MHz each in the range of 1.5 GHz in 2015, in total, the operators are therefore each 20 MHz radio spectrum available in volume 32. Depending on the modulation and the antenna configuration, at least 150 MBit / s can be reached in the downlink (64QAM, 2 × 2 MIMO). When using 256QAM, 200 MBit / s is possible and 4 × 4 MIMO is also used MBit / s available. Of course in addition to the “main band”, which is already absolutely necessary on the basis of the uplink.
