This paper considers the problem of providing gbps/user data-rate in indoor environments. The technology that we study uses the 60 GHz spectrum whose special propagation properties make it ideal when combined with antenna array technology. We present two algorithms. The first algorithm is SINR threshold based which uses dynamic spectrum allocation and adaptive modulation. We show data rates of 2 Gbps per user even when 10 users are present in a small room. The second algorithm dynamically assigns users to channels without using a fixed SINR threshold. The results show that it can achieve up to 4 Gbps/user for the 10 users case. We obtain a bandwidth efficiency of up to 12 b/s/hz.
