LTE Development Overview

Development posibility from technical view

1. LTE issue:

Forum Licensing getting documentation standarization

Chipset base station availability

2. 3GPP documentation availability:

Document bisa di download Cuma2 di:

http://www.3gpp.org/ftp

ftp://www.3gpp.org/

Informasi yang tersedia bersifat global, perlu dipelajari lebih dalam apakah dokumen tersebut mendetail dan menunjang untuk development dari level komponen.

Keanggotaan

http://www.3gpp.org/membership

Diluar keangotaan 3GPP menanggap sebagai observer yang potensial menjadi rekanan.

3. Chipset availability:

Sequans -> sqn3010 -> cpe modem only no base station made

LG -> LD100 -> cpe modem only no base station made

Conclusion:

Development kit availability:

Development kit yang tersedia adalah evaluation kit dari chipset FPGA yang di gunakan, tidak spesifik untuk LTE system.

Devlopment menggunakan chipset altera tidak recommended, mengingat banyak komponen lain yang di butuhkan.

3.3 Xilinx – Wintegra

Xilinx

Xilinx bekerja sama dengan wintegra dalam mebangun LTE system.

Design xilinx-wintegra:

Development kit yang tersedia:

LTE Baseband TDP Downlink Tx Reference Design v1 (Implements all downlink layer1 channels specified by the 3GPP-LTE specifications. PPC440 based EDK project targeting V5FX70T / ML507. Source code design instantiating the following LogiCOREs: LTE Turbo Encoder v2, LTE MIMO Encoder v1 and FFT v5. Documented in XAPP1115). Reference design Xilinx, Inc. LTE Baseband TDP Downlink Rx Reference Design v1(Simple UE emulator, PPC440 based EDK project targeting V5FX70T / ML507. source code instantiates the following LogiCOREs: LTE Turbo Decoder v1, FFT v5. Documented in XAPP1116). Reference design Xilinx, Inc. LTE Baseband TDP System Reference Design v1 (PPC440 based EDK project targeting V5FX70T / ML507. Source code integrates LTE Baseband TDP Downlink Tx and Downlink Rx Reference Designs listed above. Documented in XAPP1120)

Wintegra

Wintegra yang digunakan pada LTE dengan xilinx menggunakan winpath2/ winpath3

Source: http://www.wintegra.com/assets/public_product_briefs/PB-WDS2-0607.pdf

Software yang di gunanakan: WindRiver VxWorks or Linux BSPs available

Conclusion:

Xilinx menawarkan solusi lengkap, namun sifatnya partial untuk chipset yang di gunakan dan system software yang di gunakan.

Development posibility: kemungkinan bisa di aplikasikan, namun tingkat kesulitan cukup tinggi karena system yang di gunakan lebih dari satu chipset dan beberapa software yang harus di gabungkan.

System xiinx-wintegra bisa menggunakan radio unit yang lain selain berbasis xilinx, kompabilitas denga product berbasis OBSAI/CPRI seperti product axis network (www.axisnt.com) dan radiocomp (www.radiocomp.com)

Software enodeB yang di gunakan produk aricent (www.aricent.com).

Tersedia dalam modul dengan standard AMC backplane dan OBSAI/CPRI dari interphase: http://www.iphase.com/products/product.cfm/AMC/458

T4000/T4020 menawarkan solusi lengkap (system on chip) t anpa RF Unit.

Radio unit yang di butuhkan telah diuji dan kompatible dengan product berbasis OBSAI/CPRI seperti product axis network (www.axisnt.com) dan radiocomp (www.radiocomp.com).

Software enodeB yang di gunakan produk aricent (www.aricent.com).

Tersedia development kit modul tipe: EVM-M84000-001 dari mindspeed

Tersedia modu jadi dengan standard AMC backplane dan OBSAI/CPRI dari interphase: http://www.iphase.com/products/product.cfm/AMC/459

3.5 Pichochip

Design LTE dari pico chip

picoChip’s femtocell reference designs include

associated “sniffer” functionality to reduce OA&M costs

source: http://www.picochip.com/page/31/LTE

conclusion:

Picochip seri PC202 yang digunakan masih sebatas demo LTE belum operasional sepenuhnya.

3.6 Interphase

Interphase memproduksi modul dengan koneksi backplane standrad AMC card dengan output ke radio unit standard OBSAI dan CPRI.

4.2 Radiocomp

url: http://www.radiocomp.com/Radio-Heads/3GPP-LTE-Remote-Radio-Heads.aspx

deskripsi produk:

The Radiocomp RRH platform is a technology-agnostic remote radio head subsystem that can be adapted to comply with various bearer technologies.

The fourth generation 3GPP LTE radio access standard specifies throughput performance in excess of 300 Mbps for every 20 MHz of spectrum (downlink) and very low latency, and the first commercial launches are expected in 2008.

Radiocomp RRH technology - including the most advanced implementation of SDR design concepts on the market today - will allow a highly cost efficient and high-performance implementation of the 3GPP LTE radio interface.

Fully functional OBSAI and CPRI components for fast-track design & development of 3GPP LTE distributed base station subsystems are available today from Radiocomp. For more information see the subsystems section.

The complete RRH solution will be made available in UMTS /LTE versions supporting OBSAI and CPRI optical interfaces in 2009-2010.

notes:

Klaim telah interoperability dengan interphase product i36701 dan i36702

5. EnodeB

Salah satu developer utama software EnodeB adalah Aricent

url: http://www.aricent.com/Products/LTE_eNodeb_Solution.aspx

Aricent telah bekerja sama dengan interphase dalam pembuatan module i36701 dan i36702.

Jika menggunakan product dari interphase atau menggunakan xilinx-wintegra dan mindspeed, software enobeB dari aricent telah include di dalam hanya tinggal masalah licensi dari software tsb. Sementara Freesacle tidak menyebutkan secara spesifik enodeB software yang di gunakan.
