Ofcom has put Everything Everywhere's (EE) 4G plans on a slight delay by extending the deadline for responses.

The firm originally announced its proposal to allow EE to use its existing 1800MHz spectrum for a 4G network this year earlier this month. The original date for responses was 17 April but has been pushed back to 8 May.

Ofcom said in a statement yesterday, "Ofcom today extended the period for responding to Ofcom's "Notice of proposed variation of Everything Everywhere's 1800MHz spectrum licences to allow use of LTE and WiMAX technologies" from 17 April 2012 until 8 May 2012. We have decided to extend this period following requests from stakeholders for more time to respond."

This means that EE, a business collaboration between Orange and T-Mobile, will have to wait longer for the final decision on the proposal. Ofcom's statement says that the move will not hurt competition between EE' rivals.

Both Vodafone and O2 have publically express their anger and concern over the issues recently with Three expected to join in today. Vodafone accused Ofcom of "taking leave of its senses" saying that the move would give EE an unfair advantage.

O2 said that the proposal contradicts Ofcom's aim to deliver and competitive market and "could expose the process to further risk of delay."
