Brand: Dell
Product: Dell Networking W Series 228 Wireless Access Point
Specifications
• 2.4GHz (600Mbps max) and 5GHz (1.3Gbps max) radios, each with complete 3x3 MIMO radio paths (combined and diplexed) with three separate external antenna connectors (total of 6 RPSMA connectors)
Wireless radio specifications
• AP type: Indoor, dual radio, 5GHz 802.11ac and 2.4GHz 802.11n
- In addition to 802.11n data rates, the 2.4GHz radio supports 802.11ac data rates using 256-QAM modulation. This gives TurboQAM-enabled clients a 33% boost above the maximum supported data rate.
• Software-configurable dual radio supports 5GHz and 2.4GHz
• 3x3 MIMO with three spatial streams and up to 1.3Gbps wireless data rate
• Supported frequency bands (country-specific restrictions apply):
- 2.4000 to 2.4835GHz
- 5.150GHz to 5.250GHz
- 5.250GHz to 5.350GHz
- 5.470GHz to 5.725GHz
- 5.725GHz to 5.850GHz
• Available channels: Dependent upon configured regulatory domain
• Dynamic frequency selection (DFS) optimizes the use of available RF spectrum
• Supported radio technologies:
- 802.11b: Direct-sequence spread-spectrum (DSSS)
- 802.11a/g/n/ac: Orthogonal frequency-division multiplexing (OFDM)
- 802.11n/ac: 3x3 MIMO with up to three spatial streams
• Supported modulation types:
- 802.11b: BPSK, QPSK, CCK
- 802.11a/g/n: BPSK, QPSK, 16-QAM, 64-QAM
- 802.11ac: BPSK, QPSK, 16-QAM, 64-QAM, 256-QAM
• Transmit power: Configurable in increments of 0.5 dBm
• Maximum (aggregate, conducted total) transmit power (limited by local regulatory requirements):
- 2.4GHz band: +23 dBm (23 dBm per chain)
- 5GHz bands: +23 dBm (23 dBm per chain)
• Advanced cellular coexistence (ACC) feature to effectively deal with interference from cellular systems
• Maximum ratio combining (MRC) for improved receiver performance
• Cyclic delay diversity (CDD) for improved downlink RF
Performance
• Short guard interval for 20, 40 and 80MHz channels
• Space-time block coding (STBC) for increased range and improved reception
• Low-density parity check (LDPC) for high-efficiency error correction and increased throughput
• Transmit beam-forming (TxBF) for increased reliability in signal delivery
- Supported data rates (Mbps):
- 802.11b: 1, 2, 5.5, 11
- 802.11a/g: 6, 9, 12, 18, 24, 36, 48, 54
- 802.11n: 6.5 to 450 (MCS0 to MCS23)
- 802.11ac: 6.5 to 1,300 (MCS0 to MCS9, NSS = 1 to 3)
- 802.11n high-throughput (HT) support: HT 20/40
- 802.11ac very high throughput (VHT) support: VHT 20/40/80
- 802.11n/ac packet aggregation: A-MPDU, A-MSDU
