fa'amatu'u galuega , lea e atiina ae ai se faaputuga tatala mo le faʻapipiʻiina o vaega o fesoʻotaʻiga telefoni feaveaʻi LTE / 4G e aunoa ma ni meafaigaluega faʻapitoa, e faʻaaoga ai na o transceivers programmable lautele, o le faʻailoga faʻailoga ma le faʻaogaina o loʻo faʻatulagaina e polokalama (SDR, Leitio Faʻatonuina Polokalame). Poloketi code laiseneina i lalo ole AGPLv3.
SrsLTE fa'atinoina o le LTE UE (Meafaigaluega Fa'aoga, vaega o tagata o tausia mo le fa'afeso'ota'i o se tagata fai saofaga i le feso'ota'iga LTE), nofoaga fa'avae LTE (eNodeB, E-UTRAN Node B), fa'apea fo'i ma elemene o le feso'ota'iga autu LTE (MME - Mobility Management Entity mo fegalegaleaiga faʻatasi ai ma nofoaga autu, HSS - Home Subscriber Server mo le teuina o se faʻamaumauga a le au fai saofaga ma faʻamatalaga e uiga i auaunaga e fesoʻotaʻi ma le au fai saofaga, SGW - Serving Gateway mo le faʻaogaina ma le taʻavaleina o pusa mo nofoaga autu, PGW - Packet Data Network Gateway mo le faʻafesoʻotaʻi o se tagata fai saofaga i fesoʻotaiga i fafo.
I le lomiga fou:
- Uluai fa'atekonolosi feso'ota'iga lagolago mo le LTE MAC, RLC ma le PDCP layers (Leitio Fou), fausia mo 5G fesoʻotaʻiga feaveaʻi;
- Ia faatino le tulaga masani (Narrowband Internet of Things), faʻaaogaina e faʻafesoʻotaʻi ai masini Initaneti o Mea i se fesoʻotaiga feaveaʻi, ua faʻaopoopoina le code synchronization;
- Faʻaopoopoina le lagolago mo faʻataʻitaʻiga algorithms , fa'avae ile ZUC stream cipher;
- srsENB (fa'atinoina nofoaga autu) ua lagolagoina nei le tekinolosi (Circuit Switched FallBack), lea e mafai ai ona e toe foʻi i le 3G pe a fai se leo leo pe afai o le fesoʻotaʻiga LTE e naʻo le lagolagoina o le faʻaogaina o faʻamatalaga;
- Ua fa'aopoopoina se laulau e fa'atino ai su'ega TTCN-3 e fa'amaonia ai le tausisia o le tulaga o vaega o lo'o fa'aogaina e fa'afeso'ota'i ai le tagata fai saofaga i le feso'ota'iga LTE;
- O se faʻataʻitaʻiga fou mo le faʻataʻitaʻiina o fesoʻotaʻiga i nofoaafi televave ua faʻaopoopoina i le simulator channel;
- O le RRC ma le NAS layers e sa'oloto mai le polokaina o faiga fa'aoga.
O mea taua:
- E mafai ona galulue le faiga ma so'o se transceivers e mafai ona fa'apolokalameina e lagolagoina e le Ettus UHD (Universal Hardware Driver) ma le bladeRF aveta'avale ma mafai ona fa'agaoioi ile 30.72 MHz bandwidth. srsLTE gaioiga ua faʻataʻitaʻiina i USRP B210, USRP B205mini, USRP X300, limeSDR ma bladeRF laupapa;
- Decoder fa'alelei maualuga-saosaoa fa'aaoga Intel SSE4.1/AVX2 fa'atonuga e ausia ai le 100 Mbps fa'atinoga i mea fa'atau oloa. Fa'atinoga masani o le decoder i le gagana C, tu'uina atu fa'atinoga i le tulaga o le 25 Mbit/s;
- Fegalegaleaiga atoatoa ma le version 8 o le LTE standard ma se vaega lagolago mo nisi vaega mai le version 9;
- Avanoa o le faʻatulagaina mo le faʻagaioiga i le vaeluaga o le vaeluaga o taimi (FDD) mode;
- Fa'ata'ita'iina bandwidths: 1.4, 3, 5, 10, 15 ma le 20 MHz;
- Lagolagoina auala fa'asalalau 1 (antenna ta'itasi), 2 (transmit diversity), 3 (CCD) ma le 4 (closed-loop spatial multiplexing);
- Equalizer faʻatasi ai ma le lagolago mo le faʻasologa o taimi ZF ma MMSE;
- Lagolago mo le fatuina o auaunaga mo le tuʻuina atu o faʻasalalauga faʻasalalauga i faʻasalalauga ma faʻasalalauga faʻasalalauga;
- Malosiaga e fa'atumauina fa'amaumauga au'ili'ili e fa'atatau i tulaga ma fa'aleaga otaota;
- MAC tulaga fa'apipi'i pusa faiga, fetaui ma Wireshark su'ega feso'otaiga;
- Avanoa o metrics fa'atasi ai ma fa'amaumauga fa'amau i le laina fa'atonu;
- Fa'amatalaga fa'atonu faila;
- Faʻatinoga o LTE MAC, RLC, PDCP, RRC, NAS, S1AP ma GW layers.
