Cisco Cisco Wireless 9178I (CW9178I) vs Cisco Catalyst 9178i: Specs & Price Comparison

Cisco Cisco Wireless 9178I (CW9178I)

★ 3.4 Value Score

Wi-Fi Standard: Wi-Fi 7 (802.11be, also supports 802.11ax/ac/a/b/g/n); tri-band 2.4/5/6 GHz; 6 GHz up to 320 MHz channels
Spatial Streams (MIMO): 4x4:4SS per client-serving radio; 12 SS total in default tri-radio mode, 16 SS total in quad-radio mode
Aggregate Throughput: Up to 24 Gbps aggregate PHY rate (reseller figure; not stated in Cisco's datasheet, and not measured throughput)
Radios (bands): Default tri-radio: 2.4 GHz (20 MHz), 5 GHz (20/40/80/160 MHz), 6 GHz (20/40/80/160/320 MHz). Quad-radio mode adds a second 5 GHz radio (20/40/80/160 MHz). Plus a dedicated scanning radio and a dedicated 2.4 GHz IoT radio
Uplink Port Speed: Two 10 Gig mGig ports (mGig0, mGig1) plus console; 10 Gbps needs CAT6 (up to 50 m) or CAT6a (up to 100 m); LAG caps aggregate at 10 Gbps
Max Clients: 1,200 total (400 per radio); 16 SSIDs per band
PoE Requirement: 802.3bt (PoE++, Class 6) for full performance with both 10G ports and 16 SS; 802.3at reduces radios to 8 SS (quad-radio uses 2.5G ports, tri-radio uses 1G); 802.3af runs a single 1G port with most radios disabled and no MLO. Power budget in watts not stated
Antenna: Integrated omnidirectional; 4 dBi (2.4 GHz), 5 dBi (5 GHz), 6 dBi (6 GHz); built-in GPS/GNSS with external antenna option
Dimensions / Weight: 9.9 x 9.9 x 2.0 in; 4.1 lb (1.87 kg)
Operating Temperature: 0 to 50 C (32 to 122 F)
Pricing Notes: No official Cisco list price found; resellers cite MSRP $3,009.98; observed street prices roughly $1,300 to $2,360 (RTG and CFG SKUs differ)

✔ Pros: Wi-Fi 7 tri-band (2.4/5/6 GHz) with 320 MHz channels on 6 GHz; 4x4 per serving radio gives up to 16 spatial streams in quad-radio mode; Dedicated scanning and IoT radios for security and BLE/IoT workloads; Dual 10G mGig uplinks for high-throughput backhaul; High client capacity (1,200 clients, 400 per radio); Built-in GNSS for location services; Optional quad-radio mode adds a second 5 GHz radio for capacity
✘ Cons: Full performance requires 802.3bt (Class 6) PoE, which many switches don't provide; 802.3at or 802.3af significantly reduce radio and port capability; Premium price compared with typical Wi-Fi 6/6E APs; Official datasheet does not state a PoE wattage budget or aggregate throughput; Pricing and SKU variants (RTG vs CFG) vary widely across resellers; Cisco's own deployment guide has a typo ('803.2bt') in the PoE section, so verify requirements before purchase
Est. Price: $1,442 - $2,360

Cisco Catalyst 9178i

★ 4.3 Value Score

Wi-Fi Standard: Wi-Fi 7 (802.11be)
Spatial Streams (MIMO): 4x4 MU-MIMO per client-serving radio (4 spatial streams per radio)
Aggregate Throughput: 24 Gbps aggregate (concurrent 2.4 GHz, 5 GHz and 6 GHz radios)
Radios (bands): 4 client-serving radios: tri-band 2.4 GHz / 5 GHz / 6 GHz with a 4th radio (quad-radio design)
Uplink Port Speed: 2x 10 Gbps mGig ports (multi-gigabit Ethernet)
Max Clients: 1200 (400 per radio)
PoE Requirement: 802.3bt (PoE++) required for full operation; 802.3at/af supports reduced functionality; draws approx. 30-52 W

✔ Pros: Wi-Fi 7 with tri-band 2.4/5/6 GHz and 4x4 MU-MIMO on every radio; 24 Gbps aggregate throughput for high-density environments; dual 10 Gbps mGig uplinks avoid a 1 Gbps bottleneck; rated for up to 1200 clients; supports 802.3bt PoE on the mGig ports with at/af fallback; manageable from Catalyst 9800 WLC/Catalyst Center or Meraki cloud depending on SKU
✘ Cons: Requires 802.3bt PoE for full functionality, which raises switch and injector cost; needs Catalyst 9800 controller running IOS XE 17.15.2 or later for the Catalyst SKU; Wi-Fi 7 benefits need Wi-Fi 7 clients to be realized; list pricing varies widely by reseller and SKU (CFG vs Global vs RTG), and reseller spec figures differ in places; cloud-managed (Meraki) deployment requires separate licensing; premium cost compared with Wi-Fi 6E alternatives
Est. Price: $1,681 - $2,996
