Anritsu's MT8821C communications tester

LTE-Advanced: Anritsu’s MT8821C communications tester supports Carrier Aggregation testing

  • Anritsu announces the rollout of two new software upgrades that enable testing of RF Transceiver (TRx) characteristics for 6CC CA using the MT8821C tester.
  • The upgrade enables mobile terminal, chipset manufacturers and communications operators to test technologies that support faster LTE-Advanced/LTE-Advanced Pro network speeds.
  • New software extends support for testing Carrier Aggregation (CA) technology which aggregates multiple component carriers (CC).
  • Carrier Aggregation (CA) enables higher speeds on LTE-Advanced/LTE-Advanced Pro networks.

The MT8821C is an all-in-one tester with built-in LTE-Advanced/LTE-Advanced Pro terminal RF TRx test functions as well as base-station simulation functions. The upgraded support for RF and PHY layer measurements extend the existing capabilities from DL CA 4CCs 4×4 MIMO and DL CA 5CCs 2x2MIMO to 6CA SISO and 6CA 2×2 MIMO. The new software also supports 6CA linked with Licensed Assisted Access *3 (LAA*3).

According to Anritsu, operators worldwide are deploying the LTE-Advanced/LTE-Advanced Pro standard to cope with the explosive growth in services using large data volumes, such as mobile video streaming. In addition, to facilitate a smooth transition to next-generation 5G communications systems targeted for service deployment in 2019, there are plans to introduce LTE-Advanced/LTE-Advanced Pro offering gigabit-class speeds by using even more component carriers (CC).

With the new software, the MT8821C supports all cellular technologies compliant with 3GPP/3GPP2 UE RF TRX tests including LTE/LTE-Advanced, Cat-M1/NB-IoT, W-CDMA/HSPA, GSM/EGPRS, TD-SCDMA/HSPA and CDMA2000 1X/1xEV-DO. The MT8821C also supports LTE-Advanced/LTE-Advanced Pro Downlink Carrier Aggregation, LTE-U/LAA and VoLTE voice/video echoback tests, at frequencies up to 6 GHz with a bandwidth of 160 MHz (both Tx and Rx).
