Market Context

| Max Download Speed | 2 Gbps (fiber) / 1 Gbps (cable) | up to 940 Mbps fiber |
| Technology | Cable (DOCSIS 3.1) + Fiber | Fiber and dsl |
| Data Cap | 1.25 TB (cable) / None (fiber) | None |
| Contract Required | No | No |
| Equipment Fee | $14/mo (free first 24 mo) | $15/mo (or BYOD) |
| Promo Rate Lock | 24 months | Price for Life (no increases) |
Cox’s advantage in Arizona is its widespread cable coverage and competitive 24-month promotional pricing.
